Hey guys, I came across a weird issue with my keyboard recently. Any suggestions?
Description: The laptop keyboard does not work when the laptop is inside a bootloader or BIOS. Only once the OS has been loaded does the keyboard work again.
System details: GRUB 2.02 Bootloader, latest BIOS, Ubuntu 16.04, Windows 10
Steps to reproduce:
- Boot the machine
- Press the arrow keys on the laptop during the GRUB menu
What should happen: Pressing the arrow keys should elicit a response from the GRUB menu
What actually happens: The menus are completely unresponsive
What's been tried:
- Restoring all factory default settings in the BIOS
- Checked for any settings regarding USB devices or keyboards (There are none)
- Checked for BIOS updates
- Unplugged external keyboard and rebooted
- Reinstalled GRUB bootloader
Other Notes:
- External keyboard works perfectly
- The laptop keyboard has worked in the past
- No recent changes come to mind that could've triggered this. Maybe a Windows update?
- BIOS menu can be entered (fn+F2) using the laptop keyboard, but it can't be used for anything else
