What you’re seeing
- A handful of letters, the number row or the arrow keys type nothing on the built-in keyboard.
- A USB or Bluetooth keyboard plugged into the same laptop types every key normally.
- Keys produce the wrong characters, such as numbers when typing letters on the right side of the keyboard.
- The problem started right after a Windows update, a spill or the laptop being dropped.
- Keys work intermittently, or only when pressed hard.
Common causes
Every environment is different, but these are the causes our engineers find most often:
- Num Lock or a function-key mode has been turned on, turning some letter keys into a numeric keypad.
- A Windows update installed a generic or faulty keyboard driver.
- Crumbs, dust or liquid residue under the keys are blocking the contacts.
- The keyboard ribbon cable inside the laptop has worked loose or been damaged.
- Filter Keys or another accessibility setting is ignoring brief keystrokes.
- A liquid spill corroded part of the keyboard's circuit.
Why it matters
A laptop with dead keys is barely usable for real work. Staff cannot type passwords, write emails or enter data reliably, and errors from missing characters can slip into invoices or records. Carrying an external keyboard around is a clumsy workaround, especially for people who travel. Knowing whether the issue is a setting, a driver or hardware avoids buying a new laptop or keyboard when a simple correction would do.

Frequently asked questions
Is my keyboard broken?
Not necessarily. If an external keyboard works and the problem started after an update, a driver or setting is a likely cause; spills or drops point more toward hardware.
What should I do if I spilled liquid on it?
Power the laptop off and unplug it right away, and do not keep using it while it is wet. Liquid can damage more than the keyboard if power stays on.
Can AskTechGurus help with this remotely?
Yes, if the laptop can be used with an external keyboard or mouse in the meantime. A certified US engineer connects through a remote secure session, from $99, and you pay only when it is resolved.
