I got the problem with this Asus tablet. Its battery was totally discharged - when I used multimeter it showed for about 0.15 V. The tablet did not want to charge at all. After unplugging battery from motherboard and plugging it back the charging finally started and after 10 hours the tablet`s battery had 100%. But when I unplugged the charger I found that the indication of charger is still on the screen. Even when I power off the tablet (big battery indicator in the middle of the screen). I swapped battery with my Asus Nexus 7 2013 - and found that the problem is not with the battery. MeMO Pad still shows charging indication with Nexus`s battery and Nexus works correctly with MeMO Pad`s one.
Any ideas what`s the matter with memo pad? Is it micro-usb port or charging controller? Or something else?
P.S.: Sorry for my poor english, I hope I explained my problem correct.

I've read a few threads regarding battery life but none seem to address my problem. I have the Galaxy tab running stock honeycomb bone stock got it 3 days ago still got protective tape on it. But the problem I have is I charged it all night while off from 0% to 80% (8 hour period) shouldn't it charge more then that? Also while using it at work on its charging dock plugged in via wall charger (same as when its charging at night) it seems to charge SUPER slow or not at all, it actually drains some times while plugged in. Any ideas?
Try charging it using the charger you got with the tablet, not the charging dock. I don't know exactly about the charging dock, but I know that it takes longer for the tablet to charge on USB.
Hello all,
I bought a 1000ma Samsung Galaxy Wireless Charging pad and the charging dock.
Both are rated at 1000ma. I modded the pad to fit my xperia Z since last week.
What I noticed is that the battery heats up to 43.8 Celcius while charging and then the screen turns on. I could see the notification on the status bar saying "Please unplug to save energy". I believe once the battery overheats, the phone stops itself from charging. Then it takes awhile to cool off and it charges again and the cycle continues.
Is there anyway to remedy this?
HI all,
C6903 would previously charge using an official Sony dock cord. Yesterday, however, the phone started making the 'phone flat' beepjng noise (it was close to flat), so plugged into the dock to charge. The beeping continued every few seconds, the screen rotation started playing up (I do have a screen rotation lock that hasn't been a problem) and the phone won't fully charge (the charge symbol is there, just keeps dropping. The error message "the connected power source is not sufficient. The battery is draining faster than it is charging. Minimise device usage while charging" popped up. It does charge VERY slowly if the phone is off airplane mode and the screen is off (it charged approx 30% in 10 hours, this way).
No rogue apps, etc. I reset to factory settings and the problem is still there. Phone charges fine using standard micro-usb.
Here in the NL, the carrier (KPN) send your phone away for minimum 2 weeks (& will not give you a replacement), and they will likely just test with the standard USB charger, which is fine.
Anyone experienced this & any advice would be greatly appreciated. Thanks, Adam
sounds like the cable is faulty, probably only one way to find out if you know someone with a dock - or just send the dock back to were you purchased it declaring it faulty
I've had similar issues, I solved it by rebooting the phone and plugging it in using sony usb charger until the charge is over 30%, after I got mine to 30% using usb, it then was able to charge using the dock.
you could check the dock with a multimeter, but there's not really much to the dock itself, so unless it's a broken wire, the problem is with the wall charger which the docks plugged into or the phone
Thanks all. I will check if it is the dock/cable or the power plug when my wife gets home - she also has the Z1.
Thanks again, will keep updated.

Yeah, sadly the cables don't last too long - went through 2 cables up until now and many more to come.
After the latest update (WW .18) battery life seems to be improved but today something strange happened: while in the dock and on charger I was playing Ravensword 2 (Bluetooth on with MOGA Pro). When I saw both dock and tablet where fully charged I unplugged the charger and kept gaming. After 2 hours the battery's of both dock and tablet were still at 100%! Of course this wasn't correct. A reboot didn't fix it. Full power down and restart neither.
When I disconnected the tablet from the dock it immediately shut down, because the battery was depleted. Putting the charger back in the dock gave a green light, so the dock was still fully charged! Disconnected the dock from the charger and put the tablet back in the dock > orange light at the tablet stating it was charging from the dock. Right after boot it shut down again due to depleted battery so it seems it wasn't charging at all from the dock! Disconnected it from the dock and put the tablet right on the charger > tablet charges. Waited for a while to have a little juice in the tablet and put it back in the dock > finally started charging again from the dock!
Hopefully this was a one time failure and not a new issue due to the latest update!
probably the dock software froze up hence reboot device does not fix
btw is there a way to reset the dock??

Actually I'm facing the same issue. Yesterday the tablet remained unusually long on 27% (not docked) and when I tried to access it some time later it was off. So I guess Power went out. I'm not sure if I docked it to get it recharged or did put it on Charge directly, so I have to check again.
From your description it seems that if the tablet is totally empty it cannot be charged with the Dock (which is kinda ridicilous), but has to get some juice through the charger first. The Nexus 7 (2012 and 2013) show something similar: If drained completely you cannot start them until they have been charged at least a bit.
With the tf701 it's either a fault of the software not reading the battery statistics correctly or it's an hardware issue where the circuits are unable to monitor the power level accordingly. I will try as you did, draining the tablet to zero and recharge, and after that try charging by Dock again.

Didn't work, as soon as the charger was disconnected the battery level display froze. I had to return the device.
Hi All,
I recently took out my Tf701t after not using for a while because my normal laptop died. The tablet wouldn't charge and is now dead. When I plug it in, the charging LED on both the keyboard and tablet does no light up either. However, when pressing the power button, I do get the screen with depleted battery. I can also feel static electricity when I touch the laptop's metallic back.
Is it possible that the whole thing is dead? it's very strange that neither the keyboard or the tablet's charging LED come up, even if plugged in separately and it seems like too much of a coincidence that both batteries died at the same time.
Before I took it out recently, I had it out a few days before that when I was clearing stuff from my drawer and it did turn on then with some battery left.
Any help would be much appreciated.

Do you have the original charger?
The tf701 doesn't charge with 5v chargers it needs the 15v of the original one

Hi,
That worked! Silly me, I did not even know that there is any difference between chargers for mobile devices in terms of voltage.
