Laptop keyboard works in BIOS but not in Windows

Since the keyboard works normally in BIOS and Windows Recovery, this strongly suggests the hardware itself is fine and the issue is likely caused by something that loads with Windows. I’d check whether the keyboard works in Safe Mode, then look at recently installed Windows updates, startup applications, and third-party keyboard/input utilities. If it works in Safe Mode, a clean boot can help narrow down the conflicting service or application.
