Have a Lenovo Thinkpad 470p running 18.04. There was a notification a few days ago about a firmware update that I'd never seen before, but even after clicking install it claimed I needed to do the firmware update so I assumed it didn't work.
Today I rebooted for updates/kernel patches and it started beeping at me that I assume was some sort of thermal warning. It wasn't responding to holding the power button down, so I pulled the battery before it caught fire or exploded or whatever.
now it just comes up to a blank screen (no display or backlight), keys unresponsive, even capslock / fnlock don't trigger lights. No sounds, no bios screen. The only indication that it's on is a green light, and a beeping sounded
Am I done with this laptop? Is there a way to reset to factory firmware?
