Hello!
I purchased this device some time ago and did not modify it in anyway (no rooting/flashing etc), just a stock device. After leaving it just laying around for about a month I tried to turn it on again and nothing happened. Connecting it to USB or wall charger just makes the power button red led blink intermediately.
Ive tried:
Reset button
Hard reset (vol up+vol down+power button)
Leaving it to charge overnight from the wall charger
Leaving it to charge overnight from USB
Singing to it
Specifics:
Stock firmware
Viewsonic VPAD7
Model#: VS13761
Any help would be appreciated (even as mundane as saying "its hardware is fried") etc, just want some clarify on what happened if their is no way to fix it.
Thank you in advance
Same problem
Even My Vpad 7 is having the same problem.
Can anyone shed light to the above problem?

Let's start with here -

Can you hold the "Volumn" Down button while pressing the Power button to get into FTM mode (diagnostic screen) - make a note of the basic information it displayed.
To exit/reset - you might need to use a small pin to press the Reset button at the lower bottom (left) of the device to get it to reboot.
If it does not reboot, power down or shut-off, does it stay on with only the RED LED flashing.
Probably the battery is dead or dying..
i am in a similar situation.. i can only see a Red flashing LED. the tab wont reboot, go into diagnostics or respond to any plethora of button press combinations..
For those of you reporting problems with your Vpad7 - apparently not responding & only flashing red LED, can you access/read/verify your device's FTM status? Does it show any sort of boot-up sequence at all (the 3 birds being the common one for official Viewsonic Vpad 7's?
Please re-check your mSD card - you have one inserted right? properly formatted and not corrupted, readable as a USB drive when taken out & connected to a PC? Try removing any Sim card or vice versa, insert one and try to boot it up? Has the battery being charged to 100% (using the stock 2.0A charger - typically take 4 to 8 hours)?
Since it's NOT rooted and has no custom recovery installed (right !) - even a successful effort to boot into Recovery Mode won't help at all, but, it will help if you can get into bootloader mode.
Still following ... if everything checked out up to now, it's very likely that your ROM was corrupted/damaged and you need to reflash the "correct" factory ROM (RUU or *.nb0 file) using the factory utility - as discussed in the referenced link .
If you think you know what you are doing and dare to try a DIY rescue by flashing it all over (got nothing to lose anyway, it's a brick - paperweight at this point) - see if you can access the viewsonic website and download the files directly ... if you cannot download/access the files, please post here or PM for possible alternatives from my private collection now in cloud storage (it's geared mostly for newer/ITE devices, however, but not all of it) Please be specfic with your model's firmware/build & other info as shown under FTM or see your factory carton's box for the technical info.
If it's under warranty, by all means, contact support & get RMA to return it for repair/exchange - in 2 to 3 weeks (4 ?) you will have it back in working order, good as new - no fuzz, no worries & the "brick" can fly in android again.
If none of these apply, another possibility for the advanced users daring to play in a "what do I get to lose at this point situation" - to try to connect it to PC and run ADB using terminal emulator, to try to bring it back to life or at least restart/reboot it. http://forum.xda-developers.com/showthread.php?t=1229804
Good luck & I will check back soon ...
Unfortunately, mine will respond to none of these. nothing shows up on the computer when i plug it in.. not a sound, nothing. i may try booting up my old linux partition and see what /var/log/messages has to say when i plug it in..
i have an inkling that the battery has completely died though.. its a smart battery so has a PCB attached to it. if this has gone then i doubt the tab will power up.. unfortunately, replacement batterys arent easy to source..
i will let you know how i get on with it later on tonight when the GF and Kid have gone to sleep so i have some peace to potter around the house..
cheers for all your help my friend!
Today I plugged it in to my computer.
There was a white flash on the screen then same thing happened again.
The red light will blink sometimes or it will stay on as if it is charging but nothing is showing up on the screen.
Does anyone know how to open up the viewpad 7 or a manual on how to change the battery?

removing the back is rather simple.. run a credit card or any thin plastic along the edge starting at any corner.
good luck finding a replacement battery though.. i have searched high and low and cant find then for sale to the public that isn't a bulk order anywhere.
if you do find somewhere, please let me know..
Mine is an olivepad but I think the viewpad 7 and olivepad are the same hardware wise. (I may be wrong).
Maybe we can exchange the battery with another with the same voltage rating. And maybe higher mAh rating for better battery life?
It's already bricked so I don't mind experimenting a bit.
Here are some pictures I snapped.
vpad7 wont turn on

Open vpad7. Remove the only screw top near sim/micro sd. Remove Batt. connector for 15-30 seconds, put it back turn on and charge fully. (Its bcoz of fully discharged batt.)
Thanks

Viewpad 7 won't charge battery and power on
Hi
Seems like it might be enough to just parallel connect a phone battery, with 3,7v to the battery PCB for a short period, to be able to charge the battery again.
Mogens
I disconnected the battery for 30s and assembled it back again, but the red flashing continues and it can't be turned on or charged.
Battery is over discharged.
1 - Open it and disconnect battery connector on mother board and reconnect and try to charge. If the battery percentage appears on screen appears and moving means its charging. Charge for few hours then turn on.
2 - Disconnect battery connector and charge it for 5 mins by using any 5V 1A power source for any mobile. Then put back battery connector and charge using original charger. If no other 5v 1 A source available, you have to cut the wire of same original charger and use +ve and -ve.

So I wanted CM 10 on my phone and did all the reading as was following a guide. I got as far as installing CM 10 and on the initial start-up it says it can take up to five minutes.. Well, it sits there forever and goes there every time I reboot.
Now, when I hold the volume and power buttons it goes into Android system recovery <3e> I know I had to boot into bootstrap recovery to be able to load the file off my external drive - otherwise you get the failed signature and it won't load.
Can I do anything here to fix my phone? I don't don't care what I loose, I need this working.
Thanks-
Kyle
Ok - so I'm trying to fastboot VRZ_XT912_6.5.1-73_DHD-11_TA-3_1FF_02 onto my phone bia FlashME as RSD Lite will no longer work and its telling me battery low.
I've had this plugged into a Motorola branded wall charger for nearly 4 hours and it still says battery low. Im switching to the dual usb black square charger and a Motorola branded usb cable and trying again - after this I'm not sure how I'm going to be able to charge it...
holding volume and power and going to bp tools to get the battery meter to show does nothing, sits at moto screen forever... I dont want to claim this on my insurance - but I may have to. Help?

To charge the phone, you will now need the Motorola factory Charging Cable that bridges pin 4 with pin 1...anyways this will allow the phone to charge now that it is stuck in bootloop. The bridging of the pins allows the phone to think it is in the factory programming mode, allowing it to charge.
I would include a link to the post, but I am a new member...can't post links...but Google the below search term, and there is a few sites on how to make the cable, or where to buy it.
Now, I believe this will solve your charging issue. I don't know about flashing back to stock or making the ROM work, and I would look around a little more on the subject of this cable because I just stumbled across a thread about this a few days ago. A quick Google/XDA search on "Motorola Factory Charge Cable Razr" Should be sufficient.
---EDIT---
After looking through the forums again, I found a thread that may help you...it is in the middle of this forum, and it is called Low Battery charge in Ap Fastboot Fix. Take a look at that and it may help you.
Its toast - wont charge. took it all apart, hacked a cable and put the leads on the battery and gave up. put it back together - calling asurian to get a replacement. **** this thing
Hello, yesterday I got my new Redmi Note 3. After hour or so using it, installing apps, adjusting settings and such I locked it and a minute later it didn't turn on (last time I checked the battery was around 30%). I've tried a lot of things: connecting it to my PC, holding every combination of buttons (just power button, just volume down, just volume up, power+volume down, power+volume up, I haven't tried only the volume up+volume down combination). I've also left it charging over the night using my Galaxy s3 mini charger (I live in Europe so I can't charge it here with provided charger) and still nothing, literally no reaction. Then HonorBuy's suport sent me an email that says I have to remove the sticker from the battery, it wasn't until they realised that the battery is non-removable that I have to close the back cover. Then they told me that I try charging it on the computer for at least an hour. Will that help considering that I've already charged it normally the whole night? Or do you guys maybe have some other idea what might be the problem?
I forgot, that hour or so when the phone actually worked, worked perfectly.
Thank you.
did you manage to get your phone fixed? im having the same problem. phone just died randomly.

I have the same problem.
Original Note 3, original rom. It just died and I can't get it to work. no reaction from phone.
Any ideas?
Same problem here . any idea?
Can you get into fastboot?
Power button + vol down..
Edit: Sorry, just saw that you have tried that already..
When I had a bad flash a couple a weeks ago my RN3 was totally dead like yours..
I followed this guide wich worked for me: http://en.miui.com/forum.php?mod=viewthread&tid=221115
Attention! All your data will be lost..
I'm aware that your phones was properly working, but maybe this is a solution?
Charge from PC USB.

I also got the same problem today...but i mamaged to fix it...Firstly hold vol down and power button...the device will boot into fastboot mode ...secondly after entering into fast boot mode...hold volume up + power for 10 seconds....now your phone will reboot ormally...Thats it...No big deal...
I had the same problem right after I connected the phone with an aux- it died and started heating up. I tried all the above suggestions except the reboot because I didn't want any data lost. All I did was put it in rice for 10 minutes, even though I knew rice is meant for phones when they've got wet. After 10 mins, I pressed the power button and it worked!
Hope it works for you,too.
The same problem is happening with me after I tried to restore a TWRP backup.
I can't really enter fastboot as phone is not charging.
I'm having the same issue with my Redmi Note 3 phone. Just opened it from the box, charged a bit and turned it on. Everything worked except when I turned it off again to charge it faster and later tried to turned it on.
The phone is now completely dead, no charging screen, and it's slowly heating up. Is this a manufacturing error or can I do something to fix it?

This happened to me too. I think I factory wiped in twrp and went from cm13 to miui then it stopped charging.
No amount of flashing fixed it. Fast boot, EDL nothing worked and xiaomi won't help.
I came across only few people that had this but they seemed to suggest some partition being corrupted going from CM to miui. I couldn't find details about which partition though, not very substantial claims.
I read somewhere that it could be a bug of the version of a specific TWRP, but without sure.
In my case, I flashed Xiaomi.eu with success on CM, and after that restored again CM.
CM -> Xiaomi.eu -> CM
I sent it to a (unofficial) repair center and they just flashed the ROM on my phone. Probably using pin test or something similar.

I tried all of that. I had about 80% battery when I noticed it's not charging so I had plenty of battery to flash things. I tried anything and everything that was suggested to me in the xiaomi forums but nothing worked.
Did you send it to an official xiaomi service center?
No. I just sent it to a local generic phone service center. I imported mine from China without warranty.

Well that gives me some hope. Where are you? In the UK the phone is rare so I'm worried that they won't know what to do with it.

I'm from Portugal and it is also rare her but they solve it in a few days with just a small price. Try to find a specialized smartphone repair center near you as it looks like a small issue.
I have purchase new redmi note 3 prime. Very first time when I switched it on after charge it start booting and still continue since 8 hour. Nothing happened neither switch off nor restart even hard boot is also not working. Only logo of mi is blinking on screen.
Can someone suggest me plz.
I am also having same problem. Volume down and power button also not working
I too had same issue. I held down the power button for almost 15 seconds and it booted up
So, I had my Hudl 2 for about 2 months but my mother took it abroad for about 5 weeks. It ran out of charging on the first day after which they attempted to put it on charging but it was completely flat and not working. I thought it was because we used a different charger abroad so when we returned I put it back onto its original charger but it still didn't switch on. It has now been almost a month but it isn't switch on.
Is there a way to revive it or should we try and get it repaired?
Thank You
Does anyone know how to fix it?
Is the battery is removable?

No
My suggestion is go for a service centre as I am unable to find the answer for your device, might be chances of getting battery replaced
Press and Hold Power and volume up button for 15 seconds release volume button and press power again for another 15 seconds connect mains wall charger power charging light should come on leave it charging for about 15 to 20 minutes. all done
Do you know what kind of charger was used when it stopped working? It's probably worth making sure the specs (ex: Voltage) were exactly the same as the stock one. If not, we can pretty safely assume it's a hardware problem.
If you have verified the charger is OK but the device charging light simply refuses to come on, have you considered the possibility the USB charging port is damaged?
Replacement ports are available from Amazon for a very modest outlay and replacement is demonstrated on YouTube.
Just search for "replace Hudl 2 charing port" on YouTube" using any reputable search engine. (the forum wont let me post the link.)
I managed it so it can't be that difficult. However I found it a lot easier to open up using a "Stanley Knife" than they did on the video.
Good luck.
Dug out my trusty Z3TC 16GB WiFi to browse the web and its dead and refuses to charge on 4+ different chargers. Won't respond to power+vol up or show any activity.
Software was fine when I last checked, running CM12.1 and no issues.
Anyone see a similar issue and know if the battery is likely to have failed or something more fundamental?
I'm ordering a pogo pin charger to see if that works, had a couple in the past but the connecting wires in the stand broke.

Yup, saw that thread. Looks like I'm out of luck as I certainly can't resolder any of the components.
did u try with a quick charger?
Peace to all
I've tried most chargers and I have a lot of them, including original chargers for Z3 and Z4. Even trickling on a slow charger should recharge after 24 hours but nothing.
Wish I'd remembered to keep it charged, can't even get a bootloader up.
Try this??
Press the volume up button and power button together for 10 seconds. This should cause your device to vibrate 3 times and then show the battery charging screen.
Nope, I've tried all of these already. Probably need to open it.
weird dude.as far I know,li-on batteries need to fully discharged once in 30 charges.I made it once (it closed from battery) but nothing weird happened to me.I am always on KK 4.4.4
or u can try press the tiny reset button near to usb port.here says that nothing is being erased.

Good news! Thanks to everyone here who convinced me to persevere and not sell this tablet as broken!
For 4 days I have been charging the tablet and trying power+vol button combinations a couple of times each day and finally, on day 4, I was able to first get a red led. After the led went out about 10 mins later I tried vol+power again and got the emergency battery graphic plus red led. Led went out after ten mins again and had to use vol+power. Seemed to go a bit strange at that point and charging halted. Swapped chargers and waited.
Next time was the trick, got red led, it went out and I was able to get the normal, smaller charging graphic. Let it get a couple of % for safety and hit power, resulting in a full boot. Tablet is booted at 4% and charging OK.
Thanks to everyone that helped out.
glad to hear!so can u tell us the working process so just us to know just in case?....

Exactly as per above, keep repeating the power & vol- sequence and putting on charger for a few hours. Exact brand of charger doesn't seems to matter, the one it worked on was a no-name two-socket UK plug charger from Amazon. Obviously a 2A+ charger will help. The cable used was a generic Samsung 1m (3ft) lead.
Just repeat the process and leave it on the charger in between. I'd recommend not charging a unit like this unattended in case the battery is damaged and there's a battery failure, I've seen a lipo fire and they're ugly.
Thanks dude!enjoy the best tablet! ?

Dude glad you got it working. I love mine but i have it rooted. hoping that the latest stamina battery return update is rootable
