Hi guys,
it seems my tablet finally died. It does not want to charge up (light is on when charging) and battery definetly went below 5%. It does not even show battery screen/3 led blinks when trying to turn it on.
It also has damaged screen so what I would like to do it, is to open the tablet up, change battery (could be bigger) and the screen and make something like mini-pc? I know the hardware's good, battery has been acting up for the longest time.
So, could any of you recommend me a good battery (and tools to open the tablet up) for this tablet and a bigger touch screen so I could reassemble this device into a mini-tv? Maybe a new charge port/charger could be good too so I could keep it powered on all the time. Any ideas are welcome, It is just a thing that came up to my mind what I could do with this device instead of throwing it away.

The first time I've allowed my battery to get very low since installing CM7 on my HTC Merge and I'm now having all sorts of problems.
Firstly my screen won't light up. It's just completely black. The phone is on and the 4 buttons at the bottom light up but that's all. The phone is still responding to my touch as I can load apps and hear noises if I happen to touch the correct parts of the screen. It's almost as if the brightness has been turned way down, but I'm unable to see the controls to try turning it up again. I have tried booting to recovery mode but that doesn't display either.
Secondly the battery won't charge. Since the battery is drained I can only get the phone on when it is plugged in, but the orange "charging" led at the top of the phone never lights up. It just casually flashes like it ordinarily would have done when it was running from the battery. I have two batteries and they're both doing this.
I can't be 100% sure that these problems are due to the installation of CM7 but I've never experienced it before so i'm guessing they're connected.
Does anybody have any suggestions on how I can get my phone working again.
It's also worth mentioning that it is also no longer recognised by my computer
Sounds like a hardware fault, if you have the same issues in recovery as you do in your os then its very unlikely its ROM/software related
I don't your device nor have I taken it apart so its only guesses I could give you on which component needs to be replaced, LCD or flex cable are best guesses

Want to update on this as I've just had another look at it after a while.
With the battery having completely drained, I connected the phone to charge via my PC and the orange charge light lit up and the phone went into recovery mode without any assistance from me. After about 2 seconds the screen went off again.
When the battery has charged sufficiently, I am once again able to turn the phone on and it boots up... but the screen remains blank.
If I discharge the battery and then plug it into my PC, I am able to repeat the appearance of the recovery screen, but it always vanishes before I am able to do anything.
The screen must be surely be functional or how would I get those 2 seconds of display ?
Does anybody have any ideas of what I can do to get the phone working again?
I acquired a new battery and after fitting it the phone immediately worked again. The battery was completely without charge but the phone charged it up without any problems. However, as soon as the power ran low the same thing happened; the screen has stopped working and the battery doesn't seem to charge anymore.
I have a HTC Evo 3D, which has a 1730 MAh Lithium-ion battery. I got it on 12/26/11. I've never had a problem like this persist for more than a minute. I was on Twitter doing regular stuff when my screen shuts off. I went to see if it was a screen timeout but it shut the phone down (which was weird because it had a regular battery charge). So the phone turned on and off again (because I thought it was a screen timeout). So I didn't really care at the time so I went on my computer. I just went to turn it on, forgetting the battery was drained, and it started and turned off again. So I went to charge it 5 minutes later, and the red light didn't come up. I pressed the power button and it didn't turn on. I tried with the volume button down, I took the battery out and put it back in, but nothing seemed to work. This sucks. It's not rooted. I will say it's usual problems, in the case someone out there can connect the problems.
It overheats constantly: in my pocket and it gets stuck between my mattress and a pillow or blanket sometimes at night; and it flashes red and green lights and it feels like the core is hot enough to melt.
Each day the battery life gets worse.
Sometimes it will shut off like it did with 40% battery; but I usually plug it in and it will return to 40% when I turn it on.
Sometimes it doesn't charge at first but I'll try it later and it works (tried it this time).
Sometimes the phone won't charge while it's on because the phone gets a pop-up saying it's using too much power versus what it's taking in.
It can be utterly retarded. It seems like it doesn't even know how much the battery is charged.
I've gotten pop-ups online saying my "Android's battery is drained" "Android system is corrupted" "Android battery/system is damaged". WT*?
I love my phone: it has problems but I love the 3D, the photos it takes, and how fast it is. I hate the screen because it doesn't work in spots. And sometimes if you press in certain spots red or blue will show up instead of the screen's current picture. Overall; a replacement would make the phone astounding again. But, it's been two years, and that means it has no warranty and I have my upgrade (the phone was $300, [got it on a sale for $100]), so it would probably knock off quite a bit of cost on my next phone. It would be a WASTE to get the same phone. I refuse to get iPhone. I want Android. I like my Android. I don't want new Android. I don't want to waste money. Situation complex: advice needed.
sorry to say but it is indeed a hardware problem.. you need to physically repair it!

Is it my battery? Or is something else?
Piece of cake. Although the replacement is a bit lower MhA it's a lot better than the old battery

Which replacement battery did you get?

You even get free tools and they are not junk
How to that I used ... Hard to get pass the women robot talking LOL

At first I wondered about this being a smaller battery if it would run down fast. It doesn't !!! Works very well !!!
I changed out my battery with one from the above site, but now every time I plug a USB cable in it to charge it immediately shuts off. Anyone have any ideas what could cause this? Wonder if I got a bad battery..

That could be a bad/shorted battery. Mine is still going strong! I would try and reverse everything and start over. When I did mine my vol controls didn't work. Didn't have the connector snapped down good enough
I was looking at this one (still am actually although the one you got is cheaper):

I am still trying to see if there is a setting that somehow caused my NT to freak out when the battery reaches 23%
But I have this bad feeling I will need to purchase a new battery. By the way, if the nook just shuts off watch the screen closely it usually says "battery too low" for a second before switching off. And if that is the case after plugging it in, you likely have a bad one and I would call the company to get a replacement.
I have been looking around and the only new replacement batteries I find are the two mentioned and both are 3200mh rather than 4000 of the original. How is your battery life since you changed it? Seems like it should be 1/4th what we had when new (or close to it). Or don't you really notice at this point? I have thought about ebay but then they are used batteries and you have no idea how many cycles are left, and likely hold 1/4th less anyway due to their age. *shurgs* not sure which way to go. As of now I am still having a "freak out" situation at about 23% (roughly). If it doesn't get any worse I can live with that, but from what I have read it will only get worse. :/
Anyone know of a battery app I could use to "adjust" the shut down threashold? I have one that will alert me to whatever I set so if I am not watching it will warn me so that will work if I don't have one that will actually shut it down. I know the "calibrating" apps don't do anything except delete the one file that is only usage stats from the last time it was plugged in, so I don't think there is a real way to calibrate it.
Update:
And on another note with the "spare parts" app the 'battery history' option errors with "the application spare parts ) process.com.andriod.spare_parts_ has topped unexpectedly, please try again." Is this normal? It is version 2.3.7. NT Hidden Settings app application settings/battery use works fine and shows the amount of everything that has used the battery since it was last plugged in/charged. Could this error be a sign of the problem with the phantom touches and inaccurate battery display? And if it is a sign of something broken, what and how do I fix it?
I received a replacement battery and it is doing the same thing, so somehow during the battery switch something got wonkey with my nook. It charges OK just powers off to do it. Since it's used by my kids now it's not essential to be on while charging, but I'd still like to figure this out.

Which battery did you get? And very strange it shuts off when you plug it in. Never seen or heard of that before. It should boot up if off. Or do you mean the screen goes off/goes to sleep but not full shut down when you plug it in? If it is going to sleep, that is likely a app or setting that is doing it. Not sure which but you might want to check any battery apps you have or your settings. It would also depend on which ROM you are running, stock (which I am running) or something else.
Both batteries were the one mentioned in the original post. It doesn't go to sleep when I plug it in, it completely shuts off like no power at all. It will not boot up until I unplug the USB from a power source, although it will fully charge while it is plugged in. I've never seen anything like this and I've been messing with android since my original moto droid 1.

Very strange indeed. The only thing I would say to do is turn the USB debugging on and off a few times, to see if that makes a difference. It shouldn't but if you tried two different brands of battery, sounds like it is the hardware on the nook. But that is one really weird bug.
Something interesting I discovered. While I did get a new battery, I decided to do some experimenting. Researching this issue a lot of people said you need to delete the "battery file". There even use to be a option in CWM to remove this file. The thing is the file is deleted every time you plug in the device. So that is not going to help.
Further digging found that some devices you need to plug them in and let them charge. Or run them down for say 20-30 minutes without sleeping then plug in and let it charge fully. For some devices this "resets" the battery management system.
What I found in my tests is the battery gets harder to charge with age. While the little n light might show green, it is likely only 80% charge sometimes 90%. And it takes awhile for it to really get to 100%. What I did was let it charge up to that full 100% which may take hours. I got a nice battery app that alerts me when it gets below 25% after that things can get crazy with phantom touches. I also have it set to give a audio alert when it reaches 100%, this way I know when it is fully charged.
I know the charge it fully (when it actually says 100% and I get a audio alert when this happens) before 50% or so has helped a lot. At one point the phantom touches started to happen at higher than 25% reaching almost 35%, last time I did a test to see when phantom touches started was 17% so it is much better. Not to the level when I bought the device, but still very useable.
I will put in the new battery sometime I am sure as it is taking longer and longer to reach the full 100% (but that is normal for lithium ion batteries.) it is certainly useable in this state and the phantom touch issue is not getting worse. I think the biggest issue was charging it until the n light went green and as the battery ages, the battery manger gets thrown off for some reason and charging to the true 100% helps recalibrate it.
Therefore I would run it for 20 minutes without letting it go to sleep, then charge until it is really full (usually leave it plugged in overnight and that should do it). Do this a few times and see if the battery is better.
Oh another thing I did. Power it off fully (hold down power button then tap shutoff) then plug it in to charge. Let the charger wake, reboot, and charge the device. This I also think helps recalibrate the system. Although I never did it when I ran it for 20 minutes then charged to full. But I am sure powering off then plugging in to charge at times made a difference as well.
I've just bought one of these batteries, hoping it'll be better than my old one.
It should be. It won't be quite as it was when it was new, as these new batteries don't have the capacity compared to the originals that B&N installed (perhaps a hour or two less runtime compared to the originals). But it will be better than a well used Nook Tablet battery that is fading fast.
I don't know if I need a new battery just yet, but I am experiencing the issue of the power being killed when plugging the Nook into the wall or USB (which means transfers over an SD card, which is a pain). I only spent $5 to get it and I can see why someone might have thought it was broken, since they probably plugged it in to charge it but it wouldn't turn on while plugged in. It does charge while off, however.
What I've noticed in my experience is that if I turn it on, I can plug it in while the Nook is on the N screen, and then it'll go to the Cynoboot screen still plugged in, but the second it goes to boot the OS it turns off.
Anyone have any ideas on why it would allow itself to be on until it tries to boot to the OS?
Hello all. It's been a long time since I've been to this section of XDA, glad to see it's still got some life left.
I'm trying to get my old i777 working so a friend of mine can borrow it. If I remember correctly, it was running an AOKP rom when I stored it well over a year ago, and it was fine. Today I went to turn it on, nothing. I started charging it, let it go for a few hours. It still won't turn on; instead it's acting a bit strange. Every few seconds the screen flashes either the gray battery charging logo, an instant dim flash of the entire screen (a slight gray, nothing bright), or the home/back/etc buttons flash for an instant. When the charge logo appears, the screen brightens just before it goes off. All buttons are unresponsive, my computer does not recognize it. I've been unsuccessful in finding any real help with Google and searching XDA. The only advice I found was to plug it in without the battery, then put the battery in. This did not help. Any feedback would be appreciated - this little phone has a lot of sentimental value to me. It's been through hell and back, it survived my ex (who managed to break a Nokia 3310 and Nokia 920). If I have to put it to rest, I guess it's earned it, but I'd like to keep it going for just a while longer.
Did you store it away with the battery in the phone? If so, in a year, the battery could be completely drained and in some cases, that can cause a problem with charging, as in will not charge. Possibilities to test, use a fully charged battery by charging the existing battery with an external charger, or by using another battery. This would be the first thing I would try.
I am also having such a problem from time to time, when my battery is complitely drained. I am using such a device to bring the battery back to life. Always helps.
I usually plug mine into a higher powered charger like my s6 one and that gets it out of the loop.
Hello guys, so, a friend of mine gave me his old RAZR xt910 after some begging, he was going to throw it away. This phone came to me with a dead battery and a shattered screen. First, the phone wasn't turning on, but would turn on and stuck on bootlogo only - with the charger (ac). I managed to hard reset it and load Android throu BP TOOLS (vol up down + charger), after taking the battery away, Running on charger only, - this was a new "gold" 3030mah aftermarket battery that was put in there by my friend one year ago. I was pretty impressed since it turned on without battery, like, wtf!. I tried to install CyanogenMod but could get to safestrap since it was asking for a battery ((?) image when on charger). Recently he brought me the old original battery - the one he tried to swap for the new one. It was all good, I put it back in and booted with 99%, but it depleted quickly. The phone refuses to charge it, wherever it is on or off, ((? Image when it's off, again)… it says OVERHEATING when it's on and then enters a cool down phase in which I can only do emergency calls, nothing else. On cpu-z it shows battery as Overheat at 80c (doesn't show variation). It also shows Overheat when without battery so I'm guessing this is preventing charge, but the energy flows well through the phone. Cyanogens turn the phone immediately off after optimizing apps on first boot (I guess it's because the wrong temperature data). I'm afraid... should i spend 15 dollars to try the luck on a new battery?, is the temperature sensor installed on the battery or the phone? Anyone booting from CHARGER ONLY, NO BATTERY INSTALLED getting "Overheat" status on cpu-z temperature readings? I would like to fix this phone to keep it... I like collecting phones.
After the battery depleted I managed to recharge it alone on a.universal charger, manually. I can't say its a comfortable way to charge it, but still the only way. Unfortunately I threw the "new battery" away so I can't say if it would say "Overheat " too to determine if it's a phones problem. Big fault
