Intermittent physical keyboard keys not working in some applications
Spacebar, backspace, and other physical keyboard keys were failing intermittently in some applications while On-Screen Keyboard still worked. The technician installed a pending BIOS update and reset the keyboard drivers to default, then confirmed the keys worked normally in apps.
Killed once by someone from XL.net, on 2026-06-29.

What you see
- Physical keys such as spacebar and backspace stop responding intermittently in some software.
- On-Screen Keyboard works normally.
- The problem is app-specific rather than a complete keyboard failure.
Why it happens
Suspected A pending BIOS update was present and was treated as the likely contributing issue, but the ticket does not prove a root cause.
When it shows up
