Issue with battery indicator always shows "on charge", though it is not
Posted 18 January 2013 - 08:03 AM
Everything works fine on tablet, except one thing: the battery indicator always shows as if it is on charge, though it is not plugged. It is a kind of disturbing.
I tried to calibrate battery, but it didn't help; factory reset didn't solve my problem too.
Do you have any ideas?

I updated firmware, now I am using official 1219 FW (before it was stock 1115).
Tried to do factory reset, but it didn't help.

But it doesn't help (when I type a command in the terminal it shows that "no such file or directory").
I guess, I understood why it didn't help, it's because paths on different devices are different, but after this comment (link) I am not sure that it might be safe.

Of course that didn't help, because you cannot calibrate the battery, especially not by deleting Android's batterystats.bin file (which is what those "calibration" apps do).
You could try opening the tablet (only do that if you feel comfortable with the idea and don't mind potentially losing your warranty). Then unplug the battery for a while (it's not soldered as in previous tablets, so that's convenient).
Maybe that'll help.
The "echo B820 > /sys/devices/i2c-2/2-0034/axp20_reg" stuff directly accesses hardware registers of the AXP202 power management chip. The Hero 1 does not use this chip, so this won't work.

What if change paths and names, can it help?
Well, I am not afraid to lose warranty, but a little afraid to break the tablet that it will not work after I make it back.
Maybe it is the only way...

Since then I have flashed several different FWs, from the original 1219 to 0308, to Bloatfree 0308, to 1115, to CM10. I have opened the tablet and checked inside, everything looks OK, no loose connectors, no cold soldering joints, no visibly broken components. I have taken the battery connector out for a while and plug it in again.
No luck, all the above operations have not resolved the problems.
If you would advise something else to help, I would be very pleased to try it before I send the tablet back for repair.
