I have a Lenovo T430. It boots into Arch Linux without issue but when I try to enter BIOS configuration or the menu to choose a boot device, it hangs with a blank screen.
Things I have tried:
- Updating the BIOS
- Removing the hard drive and mSATA SSD
- Disconnecting the backup battery (clock was reset when I booted, so it did take)
- Booting while connected to external monitors to see if it was set to display onto them instead of the builtin display
It's currently set up to boot UEFI only (or possibly UEFI/Legacy) with SecureBoot disabled.
I don't know what the issue is. Any knowledge would be helpful.
