My Keyboard Is Not Working: Step-by-Step Troubleshooting
No input at all? Walk through cables, Bluetooth pairing, USB ports, and driver resets—then confirm each key with a free online keyboard test.
Whole keyboard dark vs one dead zone
If nothing types anywhere, check power, cable, dongle, or Bluetooth pairing before diving into key-level repair. Try another USB port or a phone OTG adapter to see whether the host is the problem.
If only a zone fails—number row, arrows—the checker map usually shows a contiguous block missing, which hints at a flex cable or liquid bridge on laptops.
Layout guides (ANSI, ISO, JIS) change symbol locations more than letter rows. Match your OS language pack to the checker diagram so you do not remap a healthy board.
External USB keyboards are a cheap way to stay productive while a laptop keyboard ships for replacement. Keep working; do not delay the RMA paperwork.
Try the keyboard checker
Press any key on your physical keyboard and watch it highlight on a full layout—free in your browser, no install required. Use the layout menu if you type on UK, Turkish, Arabic, or other regional keyboards.
Open free keyboard testSoftware resets that help
Restart the machine, disable filter keys and gaming overlays, and test in a private browser window with extensions off.
Reinstall or update the keyboard driver from Device Manager on Windows; on Mac, delete Bluetooth pairings and pair again for wireless boards.
End troubleshooting with a calm typing test only when every key highlights green. Speed work on a faulty board trains bad compensation habits.

Know when repair is not worth it
Consumer desktop keyboards under a certain price point cost more to diagnose than replace. Laptop integrated boards follow the same economics: replacement assemblies are standard service items.
Document failing keys with the online test screenshot or notes before you call support—it speeds RMA approval.
If liquid was involved, wait until the board is fully dry before powering on. Testing too early can short traces and turn a recoverable spill into a full replacement.
Laptop keyboard economics favor replacement over heroic repair. Budget time for a swap rather than hunting individual scissor clips unless you enjoy micro-surgery.
