Hi,

I've had my TF700 since it came out and I love it. It was running CROMBi-kk for the last month or so, and my experience has never been better. However, it would die before the battery reached anywhere close to 0%. I didn't care about that until last night, when it died at more than 50%. I was surprised that the battery would not calibrate itself over time.

Anyway, I drained the battery some more, until it could no longer boot, and left it on the charger overnight. It will not boot at all now. I held the power button down for more than a minute, on and off the charger, on and off the keyboard. It's completely dead. The only reaction I get from it is the green LED on the top of the tablet when I plug the charger in. It never starts booting up, never vibrates, nothing. The ROM has been stable until now, making me think that it's hardware. If it matters, it's been like this for 12 hours, and the tablet has been in room temperature.

Is there anything I can do to turn it on or verify? I don't care about data loss. Any and all ideas are welcome.

Thanks,
- Bocete

Connect it to your PC via USB, make sure the computer doesn't go into sleep mode and let it trickle charge for 8 hours or so. The LED will not come on, but it should charge very slowly. This has helped some people to recalibrate the battery too, so hopefully it'll breathe some life into it.
BTW, it's never a good idea to totally drain the battery and let the tablet die for lack of juice.

I'll do just that.

Yeah, I had no idea. The idea came from the (good?) old format-the-battery days.

Still dead. Leaving it on USB overnight didn't help.

Darn! Sorry man...
Did you have fsync off? If you have sudden reboots (and yours seems to have died multiple times from lack of power) you should not run it with fsync off..
I know, that doesn't help anymore - just thinking somebody else may benefit from reading this.

Leave it alone a couple of days and try again. Sometimes things magically do work themselves out...

fsync off cannot cause this kind of problems - in the worst case your data partition needs to be reformatted, but the ROM will boot. In the very unlikely case that you remounted the system partition writable and you crash while writing to it, you may have to reflash the ROM too. But it can never break the bootloader or the recovery.

Nah, this rom was running with fsync and without data2sd.

I think it's time to start looking for a new one ;( Not the expense I needed, but did I use it daily.

Several people who were in a similar situation have reported that their tablet "magically" healed itself after a few days, so there is hope.

Still nothing. I think it's dead.

The upcoming TF303 looks decent. Can you anticipate how vibrant the modding community will be considering the Intel Atom? The modding community, along with your kernel work, made my TF700 usable, and I am really thankful for that. I would like to have custom options in case the stock kernel/rom do not deliver.

If Intel Atom is in any way problematic, I may try to get a new TF700. They're still being sold, and presumably not for long. The modding community for the TF701 seems basically nonexistant, which is a problem for me.

I had that just happen to me. What I had to do was open the TF700 up using the steps from iFixit and after opened up I turned the power switch slider on the main board to off for about a minute and then back on. Once I did that it powered back up again. One thing though if you're not comfortable with opening up you're Tab I would not suggest doing it because the plastic tabs that hold it together can be easily broken I got lucky and didn't end up breaking any of them. Still not sure why the Tab did this in the first place. In any case I hope this helps.
