Woot gTabber here. No problems with my device; rooted, running Vegan 5.1.1, and working like a charm...until now.
I've noticed a problem when connecting the charger. When plugging it in, the gTab won't charge. The indicator light does not come on, although the green light on the charger is on. I wiggled and adjusted the jack until it connected and that worked for a few days. Now all the wiggling in the world won't make it connect. I tested my tab with a friend's charger and it didn't work either. It seems like there is a problem with the port and not the charger.
So. What are my options here? Is this something that can be repaired?
If it was a recent purchase, see if you can get it RMA'd for a replacement unit.
I had the same thing happen to my G Tab. Received an RMA and sent to Support. Received a call from Viewsonic that it was abused!! Haven't dropped, bumped or anything else. Using it with it plugged in is just begging for that dude to break inside.
I'll advise on what Support ultimately does if anything.
Edit 6/17/11: Received unit back from support. They repaired the port under warranty after about three calls accusing me of abuse. After the repir it seems to sit in tighter than before. You should be warned that support put the 4349 ROM and 1.2 bootloader on the device and cleared everything including the sdcard. I had to nvflash back to 3588 to get it reloaded with VegaN Ginger Edition and the 1.1 bootloader.
My 2nd Gtab is the 1.2 with 4349, I have had it about 3 weeks DO NOT like stock rom so I flashed it to flashback, then went to charge it as I ran the battery down, and I have the same problem! No light, no charge, sounds like it will be a fight with Viewsonic repair. It appears that the port has been pushed in. Has anyone out there tried to do their own repair? I have to flash it back to stock if I want them to repair it, can't do that unless I can charge it. Had software problems on my 1.1 and it took forever to get it back. I would rather try the fix on my own or pay for a fix in town.
Other than that I love both my Gtabs, the Flashback rom looks good but I have not had a lot of time to play
Once again thank you to all, any and all responses are welcomed

If you're down to do a bit of soldering, pop the tablet open and make sure the power connections are properly tacked on.
tried no luck
just sent back to woot for refund
it appears that it ad been opened before suspecting they sent a refurbished. The power port was totally off the board pads. Tried to resoder must not have been a good connection. It sounds as if GTAB has a problem with this, or is it just our 2?
Think of another tablet any suggestions being as woot id giving me a refund
Let me know thx Jaye
I had the exact same issue and instead of trying to repair the plugin I ordered a dock which charges the G-tab through the HDMI port. Kills several birds with one stone.
The same problem with me. CosmicVagabond, thanks for the good idea, will do it.
Can you give me the link you bought it from? By how much did you buy it?
I have that issue as well. But wiggling the cable until I get a light generally works. I even bought another charger for it and it does the exact same thing so it's the port on the tablet and not the charger. But hey what's a little wiggling to get what you want?! And no, I've never dropped this tablet.

Hi All,
G-table power jack broke and needed fixing. I call Viewsonic and explained the situation. The tech took my information and informed me that my unit was still under hardware warranty. I've have it since late Dec and modded it in Feb of 2010 with Vegan (currently Vegan Ginger 7.1).
Just wanted to share that Viewsonic does stand behind their hardware. Hope this helps others who may need the same service.
mine broke to...
thnx for this post, my tabs charging port is broken too.. i will give them a call soon. earlier i was thinking of getting the dock and using it for charge up ,, i forgot that i have warranty..lol.. thnx for reminder post... pls let us know about the updates of your repair
Same here. My kid dropped my GTab ands now the power port is jacked. I threw away the GTab box. Is there any way to get it warranted with out the original box? Or does anyone know where to get a dock for under $40? It's ridiculous how much they charge for those things!
Anyone have a clue how much Viewsonic charges to pix the power port? I bought mine off ebay so I'm not the original owner.
I also bought a port which worked for a few days. Now when I plug it into G-tablet the power light goes off on the port.
I have a different tablet (transformer) now, but every time I see the G-Tab, I wonder if I can revive it as a second machine.
Hello All,
All of a sudden, the plug wasnt connecting into the port like it always did and after i looked online, I seen that it happened quite a few times to others. It simply will not charge now. its been dead for a week and iv been contemplating what to do so i figured is take it here before i make the final decision. If anyone could give me some advice I greatly appreciate it.
It seems there are a few options, call viewsonic and try to get them to semd me a new one since I got it in Feb but im rooted so thats out, plus I dont want the hassle. Take it apart and try to re-soder(sp) it back on to the mother board- although I hear it is somewhat easy, but I could never do it.
SO my last possible option from what iv read online, is to buy the Malata Zpad/Gtab dock. From how I understand it, I will set my gtab in the dock and it will charge, but I have a few questions/issues with that.
1) I heard it doesnt come with a power cord. Is this true? Do i need to use the cord that my gtab came with and will it work to power this dock?
2) If this dock will indeed charge my gtab, and fully fix my issue, where is the best place to buy it/fastest shipping? The only ones Ive found are around $50 with free shipping(which im good with), are shipping from China and take up to a month to finally receive.
Again I have not been able to charge my gtab for a week, and need to find an alternative way, due to a faulty Ac port, which iv found many others online have the same issues.
please community, any would be a huge help. thank you all for taking the time.
bump
Any replies would be very helpful, thanks
The charger that comes with your gTablet works with the dock. The dock doesn't come with a charging cable. Just switch the cable to the dock and you're good to go. It'll start charging as soon as you dock it.
About two weeks ago, electroniccrap.com had them in stock. Yes, it's around $50. I actually got mine through them (ordered via Amazon). It was sent priority mail, so it arrived in less than a week.
I had the same problem and I open the tablet and soldered the AC port again back to the board. And it has been working fine for the last couple of months.
Re-soldering the connector shouldn't be a problem for an experienced person with decent tools. Ask around among your friends, neighbors, acquaintances -- surely someone can do it.
You might stop in at some local computer stores that do in-store repairs -- look for a technician with gray (or very little) hair, he'll probably be excited about the prospect of actually using his old soldering iron again, just like 'back in the day'!
Right after I got my G Tab, it fell off the desk and broke the charge socket in the unit. I figured out how to open the unit up and found the metal strap had been pulled lose and also the solder connections [I think there were four (4) had been pulled lose. The metal strap wouldn't hold the socket down on the board so I bought a tube of the new Locktie GEL Super Glue. I carefully added some drops of that to hold it to the board while I did the solder job. It has worked fine now for over a year thanks to the super gel glue.
We have tile floors in our home and shortly after fixing the socket, I again dropped it from about waist high, the thing bounced back up and I caught it in mid air. Other than a little scratch where it hit the tile the tablet has worked just fine. TRY THAT WITH AN IPAD AND SEE WHAT HAPPENS. These G Tabs are really rugged as the above demonstrates. It was also interesting to see the inside of the unit. Looks pretty simple. Hope this helps you repair yours.
Oh! another imprtant thing to remember. Before you start to pop the back off, on each corner there are little plug covers, when you pop those out there are Four (4) screws at each corner. Make that your first step to remove them first.
Hi Folks,
Received a new gold prime today,
I connected the tablet to the dock and charged for a full eight hours (was definitely keeping this one). Updated to ICS and the camera update and tehn did a factory reset to ensure nice vanilla install.
Been loading a few apps, and setting up email etc etc whilst the batteries were charging and all seemed hunky dory. I then took the prime and teh dock into another room and when I put teh prime back into the dock it did not recognise the dock (did not notice until typing did not appear on screen) Oh i thought thats odd what is happening here as It had been connecting earlier. After a bit of troubleshooting it appears that :
If the dock is not connected to the power supply there is no connection between the tablet and teh dock.
If the dock is connected to the power supply and I connect the tablet, it is recognised immediately.
If I connect the dock when the dock is not powered it does not recognise the tablet, however the second I connect the dock to the power supply the tablet immediately connects with the dock!!
One further observation is that when charging it feels as if the dock is vibrating ever so slightly, but as far as I am aware the only moving parts are the keys on the keyboard and there is not a transformer in the dock as the mains (wall) plug carries out this function !!
Any thoughts or suggestions?
My initial thought is to be seeking a replacement item straight away (bit of a bugg** as waiting on a refund from amazon for a grey prime that I returned today)
Please do not bother with sarky comments about asus as there are enough threads like that, I am really seeking to find out if anybody else has seen a similar issue.
I've not heard of anybody else with this particular problem.
As much as I hate to say it, looks like you might need to either RMA (or return) it.

Mine is similar but slightly worse !
My dock connects mebe 1 in 10 times and works ok ... i have tried connecting whilst the power cable is in etc about 500 times now and its random when it decides itll work or not.
I think its a battery fault, but i've already requested RMA and itll be picked up tomorrow.
Bad thing is that its already sold out now, so i'll end up waiting forever for another one
My gyroscope is also FUBAR ... screen rotation, glowball, riptide all do nothing (and yes i have checked screen autorotate toggle ... a million times )

Im on the same boat..C1 batch with 9.4.2.11 firmware...no root
Bad dock.
I too have very similar issues. It arrived yesterday, I got straight back on the phone after reading similar problems on here and it got collected by courier this morning. I bought mine from eBuyer UK.
I also spoke to Asus technical support, who said I could quite happily send just the dock back to them for repair, but denied to acknowledge that it is a known fault with the devices.
To save time and possible problems, I just sent the whole thing back to eBuyer for a full refund. Plan to get my next one from a store so I can exchange it same day if I get another faulty one. Should the next one be faulty, I won't be purchasing another.
Best of luck to those with the issue, it's soul destroying sending back the device you've anticipated for long, especially when the main tablet seems to work fine.

Hi Kaiser,
I had read the thread you mentioned, but at teh time I posted this Q my problem seemed to be different as teh dock would only not work when it was on battery power....It was absolutely fine when connected to the mains......however as time has progressed the dock has become even more temperamental and is now failing some of the time when it is connected to the mains.
Asus support suggested that I return to shop ( I had already submitted an RMA) and given some of teh problems that folks in countries outwith the EU are having I am suddenly feeling glad of the EU as AFAIR this legislation was EU inspired .
OT Mind you I am not very happy with teh EU commissioners signing up for the copyright treaty and hope the Elected EU parliament throws it out!! LOL
It looks like my charger has gone bad after 3 months of use. I've tried ASUS online chat and it isn't available. I tried the web form and it times out on submission. And when I call the number, I get disconnected. So, having problems getting warranty repair.
Is there another charger with a USB connection I can use with it or does it has to be the ASUS model? Just wondering...
Thanks!
Brian
Quick update...I did find a Zune Wall Charger with same specs...hooked it up...still nothing...wondering if it is the cable now...
My local Office Depot has the charger for the TF101 in stock. Despite the shorter cable, will it work with the TF201?
Thanks!

Thought my charging brick had died a few days ago. The plug part had moved ever so slightly and was not making good contact. Reset it and all is good.
Guys, I'm convinced the usb connector on my 9 month old TP is defective and gets worse each time I use it. I had bought a touchstone charger to ease the connector wear but still, I was eventually having problems with USB data connectivity using store bought cables. I even sent my TP in to fix the connector and when I got it back, still no USB connectivity. Just a completely wiped TP. So HP sent me one of their "genuine" silver dot cables and low and behold it worked fine. (My original cable was lost)
Now, months later, I'm having problems with the USB data connection again. I either get the "Not enough current message" in WebOS or no MTP USB symbol in CM9. Sometimes the PC will chime positively but with an error message (can't detect device). I received another genuine HP cable and it behaves the same as the other one. Inserting them normally, they appear to be in tight, the PC will chime but Windows will say that there's a problem, can't detect device. The only way to get it to work is to insert the microusb side at a 45 degree angle tilted downward and hold it in for 5 seconds, then (ever so slowly) release the pressure to the connector. 50% of the time I'll get a Windows message that says the USB is degraded and run slower than normal (which I think means it thinks its in USB1.1 slow xfer mode) and 50% it works fine at USB 2.0 (until I pull the cable out of the connector). I also have 2 store bought cables that won't ever successfully connect to USB with the TP but work fine with my Samsung cell in both charging and xferring music over to the phone.
So what I'm getting at here is that no standard microusb cable is the same and that there must be something special about the HP genuine one. Do these cables have a resistor on pin 4 ID tied to GND pin 5? Even so, I think what is wearing the most is pins 1 & 2 and maybe 3 (VCC and the data pins) which is why it may only work by concentrating on seating those pins first. Does it make sense that the 'can't detect device' message comes up with just the data lines and ground connected but no VCC? For that matter, why would the battery symbol in CM9 always show the lightning bolt assuming pin 1 VCC is not connected?
I'd appreciate any responses from other members here since I believe without USB the TP could be bricked in case some boot code gets corrupt and you are forced into WebOS recovery mode. This has never happened to me yet and I've installed a lot of nightlies but it COULD happen, no guarantees. What is inevitable is my connector will eventually wear out and my TP will only live until the bootloader DOES get corrupt, hopefully later than sooner. This could be the case with all TP's. Just imagine if in a couple of years everyone's TP's USB port goes bad. Sounds like the devs should figure out a way to fix a bricked TP wirelessly, if that's at all possible.
Thanks,

One of my Touchpad's had the same problem in Webos it said using wrong charger may not charge or something similar and with Android ie nightly the charging signal came up but it did not charge.
I spoke to HP and pointed out that I have 2 Tablets and that swapping leads or chargers made no difference all combinations worked on one but not the other.
They agreed to fix it and replaced the part. It is now working fine. And as with yours my computer failed to recognize the tablet properly.19 times out of 20 on the one time it did I was able to back up and remove Android before HP picked it up.
I would send it back under warranty or if that has expired state that it was preexisting. Otherwise as you said it is going to become pretty much unusable.
Don't let them fob you off.
Good luck

Thanx for your prompt responses. I bought my TP at the 2nd fire sale through BB in early Nov so I still got a few more months but I would rather wait a bit more since they did nothing the 1st time around. I think the connector is on some daughter board along with the vibrate device which is soldered to the main board. Doesn't sound like a big deal to repair it. Still, what makes the HP cable different then the others? Are there known cables I can get online that might be made better to always work and make better contact than the HP ones?

Thanks for your advice. Did they fix everything that was intended? Was turn around time no longer than 2 weeks for each repair? When was your last repair (busted speaker) done? Is your serial number the same or did you ever get a replacement (meaning a refurbished one) back?

i keep track of the serials and they always came back the same. i have more than one pad and i asked for one to be replaced completely. we will see if that happens. but they fix only what u ask for and nothing else.
it can take longer depending on Weekends. takes 2 days to get your box, then 2 days to get it to HP, then 3- 4 days to get your fixed unit. its all done thru UPS, cant send it out on the weekends or receive it

Hi all. I know this thread is really old, but I'm finding myself dealing with similar issues. And I'm obviously out of warranty. I can't get windows, linux, or Toolbox to pick up the USB. I'm actually in a worse case scenario mention here and am stuck in meboot, TWRP, and WebOS recovery, because I had wiped the rom. It must be an issue with the USB port, I've lost track of my original Hp touchpad OEM cable, and have tried every USB cable I can find. Any help would be appreciated.
