My laptop battery won't charge anymore, sits at 0%, and the laptop only operates if plugged to the AC adapter (it detects the power cord, but charge remains at 0%) The battery is already 2.5 years old, saw extensive use (at least daily recharge). so I wouldn't be surprised if it is damaged/beyond repair, but could it just be a software issue? I'm running Arch Linux.

1Can the bios report any info re the battery? Number of cycles , original capacity, current capacity, whether connected and recognised...– Solar MikeCommented Oct 17, 2017 at 22:26

In Mac, I know you can generate battery reports using the ioreg command. ArchLinux probably has a similar command.– MountainManCommented Oct 17, 2017 at 22:46

It's likely dead, but a common reason for this is that the charging of cells in series has become imbalanced. I've split the case for a 3-cell battery and found that one of the type-18650 cells was discharged, but two others were fully charged. Putting the discharged cell in a one-cell charger fixed the issue. Caveat: a mistake here could cause fire or explosion.– DrMoishe PippikCommented Oct 17, 2017 at 23:25

This sounds like a dead battery. If you are charging the device round the clock, it's highly likely that the battery will go out the window 2 years in.
