What you’re seeing
- Nothing typed on the built-in keyboard appears at the Windows sign-in screen.
- The keyboard works in the BIOS or boot menu but goes dead once Windows loads.
- It starts working again after a restart, or after the laptop sits for a while.
- Caps Lock and Num Lock lights do not respond to key presses.
- An external USB keyboard works at the same sign-in screen.
Common causes
Every environment is different, but these are the causes our engineers find most often:
- Windows Fast Startup restores a broken driver state from the previous session instead of loading cleanly.
- A recent update replaced the keyboard or chipset driver with one that fails to initialize.
- Filter Keys or other accessibility settings are active at the sign-in screen.
- Third-party security, encryption or remote-access software interferes with keyboard input before sign-in.
- A failing keyboard connector or motherboard component only works intermittently.
- BIOS or firmware settings disable the internal keyboard under certain power states.
Why it matters
If you cannot type a password, you cannot use the laptop at all. Staff end up locked out at the start of the day or in the middle of a meeting, often far from a spare keyboard. Repeated restarts waste time and can interrupt updates or encryption, creating bigger problems. For businesses using BitLocker, a keyboard that fails at the recovery screen can make an already stressful situation much worse.

Frequently asked questions
Why does the keyboard work in the BIOS but not in Windows?
The BIOS uses its own simple keyboard support, while Windows relies on drivers. When it works in the BIOS but not in Windows, the hardware is usually fine and the problem is software.
Can I sign in without a keyboard?
Windows offers an on-screen keyboard from the accessibility menu at the sign-in screen, and a USB keyboard also works as a temporary option.
Can AskTechGurus fix this?
Yes. Once you can sign in by another means, a certified US engineer can investigate through a remote secure session. Service starts at $99 and you pay only when the built-in keyboard works at sign-in.
