So it seems that the new motherboard IBM made me pay $700 for is locking up, and Linux is giving me confused ACPI errors I never had before. Furthermore, Linux no longer detects that I’ve plugged in the laptop power cable until over a minute after I plug it in. This is the exact same install as before they upgraded the motherboard. I didn’t even send them the hard drive, so I know it’s not the install. Nothing’s been upgraded, software-wise. I paid $700 for a faulty motherboard (it seems) and warped plastic.
I’m not happy.
