Problem

The laptop's keyboard works properly when the computer on first boots up, but if the computer enters any kind of low power state (i.e. goes to sleep, restarts, or shuts down) while still having a charged battery/power source plugged in then the keyboard stops working (even in the BIOS), except the backlight works and the brightness/accessory keys work. This problem persists in both windows and linux distros. On NixOS, the booting sequence messages a couple ACPI BIOS errors before starting and occasionally the kernel sends usb errors (error -71) which then crashes the desktop environment. When using 'showkey', some keys send very weird key presses.

What I've Tried

• multiple Operating Systems
• updating the BIOS, then flashing it back
• unplugging the keyboard from the motherboard, then replugging it
