What the symptoms may tell you
One sticky key, a whole row failing and all keys failing point to different causes. Spills can cause delayed corrosion even if typing temporarily returns.
Safe checks to try first
- 1Restart and test in a simple text field and at the sign-in screen where possible.
- 2Check layout, accessibility settings and any external keyboard behaviour.
- 3Record which keys fail and whether there was a spill or drop.
What to avoid
Do not pour cleaner into keys or keep powering a laptop after liquid entered it.
Next step
Send the exact model and a photo or list of affected keys.
What I can help with
Keyboard replacement depends on the model; some designs require a complete top-case assembly and individual quote.
