guys,
I just upgrade to .15 and since then, there is no device charging via the wall charger.
I tried to restart it 10 times, tried to plug the power while the device is off and on....nothing.
I read other people have the same issues, but how's the hell I'm solving it?
How do I restore to ver .13 manually?
Please help...its urgent... my keyboard battery almost off, and my tablet battery is on 85%...
Thanks,
Tomer
Did you try to plug it in the tablet and in the keyboard?
Both don't work?
Also I saw this in another thread :
"ANSWER - Simples, reset with a paper clip using the small hole by the SD card in the Tab. Ten seconds. Restart.
Tablet and Dock start to recharge instantly. No problems since. No setting seem to be lost, all Skype contacts, Wireless passwords intact.
Don't panic and don't send it back. Hope this helps."
If what Anthony recommends does not work, try a Hard Reset:
1) Turn off your Prime (while not plugged in)
2) Hold the VOLUME DOWN and POWER button (this takes a number of seconds!) until you get text in the upper left of your screen, then let go (you should see 2 icons in the middle of your screen
3) Just wait at this point until your Prime reboots (you will see a message about Linux Cold Boot, or something like that)
Then try to charge your Prime...
(No data is lost on a Hard Reset)
I would think that the reset button on the side or the factory reset would fix it. Are you rooted?
what does the reset button on the side do? does it completely reset the tablet?

It's the same as a simple restart (reboot), as far as I know, but it can work even when the power button is non-responsive for whatever reason.
Might be the wall plug itself. Mine crapped out for a bit... No idea why, I just had to leave it unplugged for a while, tried it again and it worked. I left mine unplugged for like 12 hours. Not saying that's like the minimum for it or anything, just how long I gave mine before trying it. There's a thread on here somewhere about peoples chargers crapping out temporarily. Some put theirs in the freezer for a while and such lol. I'd recommend looking that up and giving it a read, it might help you before you end up wiping your tablet clean or sending it to Asus or something.

He can prove its not the charger itself if:
When he plugs in his dock to his tablet, the Dock shows X% of battery left.
Then plugs in the dock to the charger for a while, then plugs it back in the tablet.
If the dock has a battery % greater than what it did initially, then the charger is working.. Otherwise either BOTH the tablet and dock stopped charging coincidentally, or the charger is broke
the rest hole next to the MicroSD solve the issue.
Thanks guys.
appreciated!

Well I updated this morning and mine is not charging. Tablet charged fine last night overnight. Here is what I have tried so maybe someone can add any other tests that I may have missed. (no dock)
Tests and results:
- I have tried multiple outlets in my house. No charging
- I can charge a nook tablet with the Asus brick and that charges fine
- I can transfer data back and forth with the data connected to my laptop
- With the Prime off and cable connected to the brick or laptop and then connected to Prime, Prime starts up, so it looks like it senses the connection.
- Did a full data wipe and all tests done with Prime at default mode; nothing. Also did a hard reboot; no luck.
- Tablet seems to charge very slowly (although no indication that it is charging) when it's plugged into the Asus brick or Nook brick and then shutdown.
I just put the Prime charger in the freezer for 30 min to see if that helps. I had to do this before with my TF101 when I had it. I can't see it being the cable because I just left it overnight last night to charge plus I don't a spare one to test with.
The Nook brick doesn't charge the Prime when on (will test this out when the Prime starts charging correctly; would make a great alternative charger)
Even though it looks like is can charge will completely off, that is a major inconvenience and an RMA should fix that.
I'm having a problem. At first I thought I was just closing the "lid" too quickly and not watching it fully shut down like in windows sometimes things will crash and if you don't click on shut down again it'll just sit there waiting for you to ok the force close. But then I started to make sure it was fully off before closing the lid. Friday I shut it down dock and tablet fully charged. Today I open the lid and the thing has been on for a long time. The dock has been fully depleted and tablet at 52% meaning it turned back on not much longer after I shut it down.
Is anyone else having this problem? I don't have it to wake with keyboard thing. I can't figure out what's wrong. I'm not accidentally turning it back on either b/c that power button takes quite a lot of depressing to turn the unit on. The power button is also facing toward the top of my briefcase. My briefcase has no closing flap either.
Sorry for posting it in general. I was browsing both the QA forum and this one to see if anyone posted.. apparently hit the make new thread button in general instead of QA. If a mod can move it instead of deleting I would appreciate it!!
I think this answers your question.

Sorry it doesn't. I mentioned that I made sure it was shut down before I closed the lid I watch it shut down, vibrate, leave the lid open while I pack the rest of my stuff up. Then I tap on the keyboard/swipe my finger across the touchpad and it's still not responding then I close the lid. I've even tried pressing the power button quickly enough that if it were on it would immediately light back up but nothing happens. I don't press it long enough to make it boot back up. I watch it for a few seconds after that too before storing it. I really thought I solved it too last week when I would try all that and watch it turn off but I was so surprised to open the lid on Sunday and see its been draining all weekend.
It works for me if I wait at least 10 sec after it vibrates.

Nothing special. I had the same question as you. I applied as suggested and it worked. Nothing more I can say.

Since this happens when you have the dock connected, did you try changing this setting:
Settings > Asus customized settings > Battery Saving > "Disable wake-up function on keyboard when the tablet is asleep to save more power."
Check this box and then turn your tablet off and see if it restarts itself. There might be a stuck key on the keyboard that is registering as a key press which could be turning your tablet back on.

I talked about how to do when disconnected. Would you give a try ?
About when it is connected, I don't understand the point. Who cares if it is really turne off or not ? It charges anyway. No ?

If the tablet is connected to the dock and is left on and unused, it will still drain the battery on the tablet and the dock. The longer it is left on and unused the more battery will be drained. If you completely deplete your batteries in such a manner and leave them depleted long enough you will destroy the cells and they won't be able to hold a charge.
Also, the tablet should complete the shutdown process even if you close the lid before it finishes shutting off. That is the way that it works on my tablet. Even with the lid closed, my Prime completes the shut down process, vibrates once and then it is off. When I open it back up later, I have to press the on-button for the device to restart. There shouldn't be any waiting period necessary.

If it doesn't work you might wanna do a hard reset on your tablet. This sounds like a software issue and hard resets are usually pretty good at resolving small software issues like this one.
Just back up your date first.
Mine works fine. Cut it off, waited a few seconds, and closed it for half an hour. Had to cut it back on when I opened it up.
I still have the issue on some boots where it'll never enter Deep Sleep, so my dock will get eaten before I notice it, but nothing like this.
I'm having the same issue, turns back on
Not the same as the OP but I've noticed that if I power off my Prime and then plug it into the wall charger it turns on and boots back into ICS. At first I thought that I had hit the power button with the hand that I was holding the tablet with when I plugged in the cord to the socket on the bottom of the tablet but I was careful doing it subsequent times and it happens every time.

Mine does that too but I think its supposed to depending on the manufacturer? My bf's galaxy nexus phone and his old Droid did that too. My evo stays off though. It makes me feel like I'm saving the battery from discharge recharging as much if I can keep it off. But at least it will turn off if you leave it plugged in when you shut down. The Droid didn't seem to let you do.. kept wanting to be on anytime it was plugged in.
Thanks almighty! I'll try the reset... Time to back it up!
My Nexus S phone, if powered off first, stays off when plugged into AC. The Prime is my first Android device that exhibited this behavior... Had a Motorola phone before the Nexus S that would stay off when charging as well. Seemed weird to me when it first happened...

OK, straight off the bat, this is my nans phone so I don't know all the specifics.
Basically she was using the phone (playing a card game let's say) and the phone just went flat, it had a reasonable amount of battery, but it just turned off (instantly). When she tried to turn it back on, no response, it wouldn't do anything, she plugged it in to charge and still nothing.
Now a day later I plugged it in and it started to charge so I turned it on, all was normal in the phone... has anyone experienced this before? Should I take it back to the shop or keep using it and hope it doesn't happen again.
Thank you for any help.
I have attached a screenshot of the battery screen
waooh , strange thing
i never had this , it seems like micro shorcut .
maybe battery isnt correctly connected ?
If it were me I think I'd take it back and get it replaced.

Anything that you can get things replaced with SONY doing it right away.
You paid premium price and should have a premium experience not a cheap knockoff experience.

I've seen similar issue with my Arc, but that after I've taken off the battery and put it back.
I assume that this could be more of a calibration issue of 75% and 25% of hardware issue.
Hey I seem to be having some trouble with my Nook Tablet. I've got the 16gb version, bought it within the first month or so of the tablets getting released. It's been running fine, i have it rooted, ran cm7 for the longest time on it, switched to cm10.1 more than a few months ago and everything was pretty great, then crap started going downhill.
I noticed that when my battery would get down between 20-30% it would just shut down. The low battery screen would come on for a split second before the "tablet is shutting down" screen would pop up in front of that and it would shut down.
Now, since then it's been happening more and more. When it's at anything lower than 96ish% it'll happen. But it's got some weird symptoms.
- The screen freaks out. Like there's 100 fingers on it pushing a ton of crap at once, when I'm not touching it at all. it's sensing a bunch of false touches that usually ends on the Google Now screen before getting the same old low battery, then tablet shutting down notifications.
- It only happens when it's running on the battery. It's never ever happened while it's plugged in.
- It only seems to happen when the wifi is on. If the wifi is off and i'm at home just reading a book or something, it'll drain all the way down to 15 or whatever before telling me the battery is low, I plug it in, all is fine. If the wifi is turned on the freak out happens.
- If it starts freaking out and I plug it in while it's happening, 1 of 2 things, It either completely stops and everything works fine, or it just turns off dead right there, not shutting down, just turning off.
- I HAVE had it drain pretty low (around 23ish) with the wifi on, but it did do the same freak out thing once it got there. It just seems to be so random when it happens, any time the battery is between 15 and 96%.
- If I turn it back on after a freak out without plugging it in first, it will restart fine, then last about a minute or 2, freak out again and shut off. If I turn it on again after that it'll do the exact same thing. And if i turn it on again after that it'll get to the CM10 boot screen, just about to where it's going to go to the lock screen, then boom, makes the beedoop battery sound and shuts off without ever actually showing the lock screen. THAT happens everytime just like that. If I plug it in first and then turn it on, it runs fine.
I've tried factory reset and reinstalling and all that stuff, nothing seems to be working. I even started from scratch not letting google or titanium backup restore my apps, completely formatted and wiped the sd card when reinstalling, nothing seems to be fixing it.
Basically this thing is useless without being plugged in. Ive even lost a 32gb sd card because of it's constant just turning off screwing it up (i'm guessing) since it's not being properly dismounted or whatever before being shut off. That card cant seem to read/write anymore. I now have a 16gb in there I'm hoping wont get screwed up because of the same thing (although I'm sure it will eventually if this isnt fixed)
Is this a battery issue? A hardware issue? User Issue? Can anyone help? I can provide any information you might need.
I've been searching for months trying to find an answer, but the symptoms are so weird I cant find anyone having the same problem as me..
Also, my fiancee also has the same Nook tablet, bought them the same day, rooted and hacked them the same way that day, and put CM10.1 on both of ours the same way the same day, hers is fine, mine is acting a fool. (I also use mine about 1000x more than her though, I use mine for EVERYTHING, EVERYDAY, she reads Sandra Brown books and watches YouTube movies once every month and a half)
Help? =[
the finger touch thing at random on your screen without touching it is your charger cable , its a crap cable , i had this happen to me too , B&N will swap the cable and charger for free, i highly suggest you do that and get a new one swapped , mine still has issues , when its plugged in and charging , i sometimes cant use the touch screen , its the charger , they are like 1 in 3 garbage and cheaply made ,
take it to the store they will swap the charger for free, if they hassle you ***** up a storm , they are supposed to just swap them , its well known fact the cables are cheap garbage and not easy to get new ones that are not garbage, i use micro usb's it takes longer to charge but i get quality cables from amazon cheap as piss 2.49$ if you want the link ill find it , again takes longer to charge , but i no longer have touch screen issues and can use tablet while its charging ill re read the rest of your post and make an edit if i can help on anything else
spyder
how long are you charging it for at any one time ? i do believe if my memory serves me right , theres a problem with the battery level on both cm 10 and 7 , seven is way worse, the battery level is not reported correctly , its being worked on by better minds than ours , im sure one of em will chip in here shortly ,
if i were you you have cynoboot installed to emmc ? i would turn the thing off completly , and charge the **** out of it , with a good cable , id use your girls cable it sounds like she got a good cable. like leave it over night charging on hers while you sleep , then in the morning boot it check the batt level in cynoboot and then in cm10.1 , im keeping mine juiced up , last time it died it ended in a boot loop that i had to unplug the battery to fix , most people dont want to crack a case even though its easy peasy ,
again , try her charger , if your powered up check how long it takes to charge fully it should be 6-8 hours on the nook 2.1 amp factory charger , i think you need a new charger though , i would try to swap cables until i found a good one , then look at ipad travel charger they are 30$ , but they output 2.1 amp and apple crap is quality which is why its 30$ , or look for a samsung galaxy tab charger USB output 2.1 amp ,
Ahhhh.. see. The battery level being reported wrong makes sense for why it happens so randomly. Another interesting thing you said was it should take 6-8 hours to charge with the stock charger, mine was reporting 100% battery after 2.5 - 3 hours charge time. This could be the problem.
I did what you said, let it charge overnight, and it did the same thing, but, not until it got down to 32%. Which is better than 82% shutdown.
When I get home tonight ill plug it in immediately and not touch it until tomorrow morning, well see what happens. Thanks for the response.

I may have figured this out. I switched my rom to aokp 4.2.2 and then flashed the showtime kernel, set cpu tuner to no more than 999mhz and all seems to be running fine. Bbs says 14hrs on battery, deep sleep for 9 of them, and I'm at 69% battery now. (Bbs started collecting at 91% for some reason instead of 100%)
I flashed the rom yesterday around 6pm, let the battery go all the way down to the first time it randomly died, then just charged it back to 100% and I've had it off the charger since then, 14 hours now according to bbs. Ill report back if it freaks out or something later.
Edit: turns out this didn't work.

I might have a solution for the battery problem. Do you have any microUSB chargers lying around? maybe for an old cellphone? If you do, use that to charge your Nook Tablet. It works, but it's slow, takes 8-9 hours for a full charge (5% to 100%) @ 500mA current. My old Motorola flip phone's charger supplies 5V @ 550mA. I'm pretty sure you have one of those lying around in the attic or garage. Anyways, let the NT charge to 100% using a microUSB charger (not the Nook Tablet's stock one, the cable is faulty and I am sure of it).
Once it's charged to 100%, go on YouTube and watch a few videos. If the battery goes down steadily, that's good. If it goes from 100% to 80% or less suddenly, there might be a problem with the battery calibration or the battery's going dead.
I bought a Nook Color off eBay that the seller listed as broken, except it wasn't. The battery was simply dead beyond the capability of the Nook's stock charger to revive it. I used the old Motorola charger. It took 10+ hours, but finally my Nook Color booted up, although with 18% battery life only. No matter what, it would stay at 18% until it shutdown without a warning. The solution to this was to delete a file called max####.bin in the /rom partition, then reboot.
Steps to recalibrate the battery (ONLY try this method if you're sure the battery needs to be calibrated):
Open the terminal (once you are 100% charged. You'll know this if the power adapter isn't warm anymore)
Type in "su", allow root access for once
Type in "cd /rom"
Type in "ls" (that's a lowercase L and S)
Type in "rm max#####.bin" (where ### are the numbers there)
Type in "exit"
Type in "exit" again
Hold down the power button and reboot. Once it reboots, it might show question marks on the battery meter before going away shortly. Hopefully, your battery will be successfully recalibrated.
Hope that helps.
Thanks a lot for the reply. I definitely have a charger lying around so ill try this tonight when I get home.

Just got done testing it out. I charged it for about 16 hours, pulled it off and powered it up, my battery status said charged, then 100, 99 etc. Once it got down to 87 it freaked and died.
The battery did drop way fast though. Like 100 to 87 in under 15 mins. Not instantly though.
If you search "nexus 7 phantom touch" on youtube, you'll see exactly what my nook is doing, only difference being the nook dies after about 10-15 seconds of the screen freaking out. And it ONLY happens when not plugged in.
If my battery calibration is off, would that mean maybe it could actually be around 15-20%, even though its reported as 100%, and not letting it charge passed that? Or is my understanding a bit off?

Right. My Nook Color was showing 18% charge no matter how charged or discharged it was (until I deleted the max#####.bin file).
Try what I said, delete the max#####.bin file and reboot. That will recalibrate your battery. If after that it still shows the battery draining way too fast, that means your battery is going dead.
Ok, so I reset the battery stats and now I'm seeing this.. this doesn't seem right at all..
I let it hang out for a while and it did the usual freakout/shutdown when bbs said it was at -22%, android showed 69%.
I think ordering a replacement battery or finally just getting a nexus 7 is the fix at this point?

Or actually, you might find "for parts" Nook Tablets on eBay for <$30. I would use the battery in there instead of buying a cheap chinese made battery (which are always of garbage quality, not to mention dangerous). You could also use a Nook Color battery in there, but you'll trade off 3 hours of usage time. Nook Color batteries on eBay sell for $7 used, but genuine.
Before you buy anything, try doing a complete wipe and reflash of CM10. Boot to CWM > wipe battery stats, wipe data/factory reset, wipe cache, wipe dalvik cache; advanced > wipe system partition; go back > flash CM10, flash gapps, flash CWM (if not already installed).

Awesome, thanks for all your help man. One more thing, I'm running CWM recovery v. 6.0.2.7, there's no wipe battery stats option in advance (or anywhere else I can see). Is it hidden somewhere I'm not looking or not in this version? Is there a newer version I can flash I overlooked?
Btw, http://www.newpower99.com/Barnes_No...cement_Kit_p/barnes and noble nook tablet.htm this was the battery I was looking at for $40, but the used nook from ebay seems like a better idea. (Cheaper too, which I like)

The CWM I used was a bootable microSD one. It had the option to wipe battery stats. At best, it will recalibrate your battery, nothing else.
I followed Ray Waldo's instructions (he's really good at explaining things in non-technical language). Download link also posted there.
You can use any Linux distro with GParted installed to set the boot flags on the card. (I highly recommend Debian, been using it for 4+ years).
http://raywaldo.com/2012/05/root-nook-tablet-with-cwm-sdcard/
I wouldn't buy that battery off the newpower site. It's a scam. You'll get a really crappy battery (3200mAH, probably chinese made, and unreliable). I would much rather buy a used GENUINE battery for the Nook Color or Tablet than a cheaply manufactured one (selling for an unreasonably high price).
If clearing the battery stats and doing a full wipe and reinstall doesn't help, I would buy a Nook Color battery for $7 off eBay. This is the last one supposedly (doubt it) http://www.ebay.com/itm/Nook-Color-...863?pt=LH_DefaultDomain_0&hash=item27d5fc185f
^^It's genuine, has a 4000mAH capacity, compatible with both the Tablet and Color, and wont explode in your face. (You really don't want to take chances with cheaply made chinese li-ions. Look on YouTube for li-ion fires/bloat (expansion)/explosions, not pretty). Be sure you also have a Torx T5 screwdriver to open up the NT. If you don't, order a set off eBay. (P.S. Don't get the chinese made ones, they're cheap and they don't work. Get a set from Craftsman if you can, those have a lifetime warranty).
Gotcha. Will try everything you mentioned and if no luck ill hit up ebay. Thanks again for all your help (and saving me from a potentially harmful choice of battery)

Have you have made progress?
Also, let me know if the battery (if you ordered one) works well. I think my Nook Color's battery is about to kick the bucket. It takes like 15 hours to charge from 15% to 100% (compared to 8-9 hours for my Nook Tablet, using the same specced charger).
My 16gb nook tablet with CM10.1 is doing the exact same thing as yours. Random touches and sudden shutdowns. The OS does not know how charged the battery is. I am eager to hear your results.
Hi guys. Is there any fix for my P7500 tab?

Oh sorry. APX i mean. my question above is now edited. Any idea sir? or i should brought it to samsung service center?
Maybe the only thing to try at the moment would be the old battery drain technique... Usual means is to tape down the power button and wait days and days until it is dead, really dead ( shows nothing when connected to computer), then connect to wall charger and reboot and see what you get. This is really the ultimate "hard reset" but same result can be obtained far more quickly by removing the back and disconnecting the battery for a while to remove residual charge... Not as frightening or difficult as it might seem, have done it loads of times for various faults and to replace batteries in several tabs.

thank you sir. Im doing it now. But Im a doing it correctly? i just connected it to the computer for apx mode then after that i tape the power button so that it continuously on and off for apx mode then i disconnected it to the computer or I should leave it stay? i think it will charge if i connected it to the computer.
If you're trying to discharge by taping down power button just leave the tab on it's own not plugged into anything... Plugging into something that charges rather defeats the object of the exercise

Samsung Service Center
Thank you for the help. I think I need to bring it to service center. There's no battery charging icon when I charged it. I dont know if its well drain but I use a laptop cooling fan via OTG to drain it. the fan and the lights from the cooling pad is not functioning anymore so i try to plug the tab to the wall charger and nothing happens.
By the way thank you. :good:
Any luck?

In some cases it takes more than a day, be patient... Unless you are prepared to remove the back and unplug battery... The aim of the game is to completely power down the tab and remove residual charge in components, the "hardest" reset available.... So, two ways to achieve that is drain battery or disconnect battery... If you drain battery you must be sure it's empty to achieve desired effect then you obviously cannot restart it without charging a bit as the battery is empty, so you connect charger then try to boot, but the tricky bit is being sure the battery is completely drained otherwise you are just wasting your time... That is why battery disconnect is preferable

How do you disconnect the battery to discharge. I tried the taped power button for five days and it still seen by PC in Device Manager.

Suggest you go here http://forum.xda-developers.com/showthread.php?t=2325109 download the manual - then unplug the battery for 10 mins or so to remove any residual power, reconnect and see what happens
Good luck
Edit....I got beat to the post. I would follow the advice above first.

Look for some videos on YouTube because it involves removing the back of your tab. So see seeing it done is a great help.

Many Thanks to You stinky73
I had to purchase an iFixIt repair kit to get the correct driver to remove the two screws. I disconnected the battery, waited ten minutes and when I reconnected I was SO HAPPY to see the battery charging icon. I charged for a while a fired up the tablet. Everything was the same as if nothing happened. I am so happy because Samsung said they could fix the problem and it would be a flat rate of $150 which I don't have and I would lose everything.
Many thanks

How hard was removing the back? I'm wanting to do some building for my 7510 and will be using it for testing so I'm most likely to brick it at least once or twice.

It took me longer to remove the screws then anything. I stripped them and will need to replace them. I tried a regular screwdriver before the tri-wing screw driver and paid dearly in time. Once the two screws were removed, use a plastic pry tool starting on the bottom where the screws are because once the bottom and sides are pried lose, the top will slide over the extended audio jack.
1.5 hours to remove stripped screws
10 minutes to pry open
1 minute to disconnect battery (did not remove battery or three data cables on top of battery)
10 minutes wait for discharge
3 minutes to re-connect battery cable (it slides forward and snap down)
2 minutes to replace case

Forgive the gravedigging, but I am unable to find anything regarding my situation, and the original poster has a problem that is similar to mine (my thread is http://forum.xda-developers.com/showthread.php?p=52931715 ). I hope someone is able to give me a hand here!
I am wondering, it has been over 15 minutes since I disconnected the battery completely, but connecting the P7500 to my laptop still shows an APX device being connected. Could there be some hardware issue preventing the device from being fully discharged?
Thanks in advance for any help!
Still no joy with waking the tablet up

I've got the same issue as Lightside and the original poster. Mine is a GT-P7500, which had CM10 nightly ROM with CWM recovery. I sold it on eBay, but before selling, I wiped the tablet and got it back to the Clockworkmod main screen. I turned it off completely and shipped it to the buyer, ready for it to be registered by the new user.
The buyer received the tablet and from the e-mails I received from him in the first couple of days, all was going well. Then, a couple of days later, he sent me an e-mail saying that the screen shows the android lying on its back with "Odin download" mode showing. A day later, he sends me a messaging saying that he can't turn the tablet on at all. The guy who bought it is an old man and didn't know much about fixing the issue. I asked him whether he powered the tablet off while still plugged in to the wall charger and he confirmed that he did. I asked him to return it to me and I can try and fix it, so now, I have the tablet back and it won't turn on. Here's what is happening:
1. I drained the battery using the cellotape method
2. Installed the NVflash drivers
3. Waited for the battery to drain (almost 9 days and the LED flash stopped blinking, so assumed it was completely drained)
4. Plugged it in to the PC and it immediately showed up again as a device under the USB controllers within Device Manager
5. I then unplugged the battery by opening the back of the tab, left it for 15 mins, then tried the wall charger again, but nothing. No charging icon on the screen.
When I try to press the power button, I can see the LED light up, but the screen is still blank.
Could this be a hardware issue and if so, what do you think could have caused it?
Could really do with some help here, folks! I don't want to have to give the buyer a refund because technically, he got it when it was in working condition and he probably did something to screw it up, but since he's an old man, I thought I'd try and help him, if I can.
