Summary of likely causes and practical next steps for the Toshiba Satellite A105 described by : an internal keyboard that is completely dead while an external USB keyboard works usually falls into two buckets — a hardware fault in the keyboard assembly or its connection, or a firmware/OS-level driver/keyboard state problem. correctly flagged connector/assembly faults as common; pointed toward firmware/driver checks that help narrow the fault domain.

A concise diagnostic checklist (adds steps beyond earlier replies):

  • Power/EC reset: fully power down, remove AC and battery, press and hold the power button ~30 seconds to discharge and reset the embedded controller, then reconnect and test. This often fixes keyboards that stopped responding without visible damage.
  • Out-of-OS test: boot into BIOS or a Live Linux USB to verify the keyboard outside the installed OS. If keys respond before the OS loads, the problem is software/driver related; if they do not, hardware is likely.
  • Driver/device cleanup: in Windows Device Manager uninstall internal keyboard/HID keyboard entries (leave the external device if present) and reboot to let drivers be redetected.
  • Visual inspection and reseat: look for sticky keys, debris, or liquid residue. If comfortable with basic disassembly, check the flat ribbon/ZIF connection under the keyboard bezel — reseating it carefully can restore contact. Use ESD caution and avoid forcing latches.
  • Failure pattern: a few working keys suggests matrix damage; total silence points to a connector/assembly or motherboard interface issue.

Repair and temporary options: on many A105 models the keyboard assembly is a low-cost replaceable part; local repair shops or used-part sellers can fit one quickly. Temporary workarounds include continuing with an external USB keyboard or the on-screen keyboard until a repair decision is made. Caution is warranted with signs of liquid damage — that can require board-level work beyond simple keyboard replacement.

More than likely a stuffed keyboard connector, happens all the time on laptops. See if you can find a friendly hardware outfit! grab a new keyboard and have a crack at this (if your up to it) : Most toshiba's are the same or very similar

Try going into device manager and see if you noraml keyboard is listed.

There should be two keyboards. Also see if you can use you laptop keyboard by entering BIOS at boot up - Then exit BIOS without saving.
