Battery report

Gabriela,

I have very precise records of when I swap over my batteries [because I run battery reports both before & after] and the moment of opening up the computer or changing the battery does not show up in my battery reports.
- My Battery report section Usage history - History of system usage on AC and battery goes all the way back to when the computer maker finished setting the computer up [and then posted it to me]. Your corresponding records seem to show the same.
- I know of no command to reset the parameters listed in a battery report.

The Start time entry you circled in red shows the time that the computer was turned on or awakened on battery power. There is no indication of anything dishonest being done. Windows re-starts that list whenever it feels like it. There is nothing significant in that entry at all. Just for example, my Battery report Start time entries are only showing for today but the computer was in use yesterday and earlier on battery.

Acer battery won't charge

What if the battery unremoveable? Should I disassemble and remove it? also there is a switch underneath the case and around the RAM slot that prevent the laptop to turn on when the case is open and without the charger. Is that the same as removing the battery? although when turned on with charger, the laptop still see the battery. Thanks

I took the report, the design capacity was 41.440 mWh but full charge capacity is now 25.752 mWh. Is it that bad? Before this happened I believe HWMonitor also show the same number with 38% Wear Level.
Here's the report file
