I've recently encountered an issue with our laptop freezing up when we touch any of the keys on the keyboard. I can hook up an external keyboard and it works fine, but the internal keyboard locks up the mouse and will not type. How do I troubleshoot something like this?

Has the laptop ever had anything spilled on it? About the only way to troubleshoot is to replace the keyboard and see what happens, but you could try uninstalling it in device manager and rebooting.

No one is owning up to any spillage. If I uninstall the laptops keyboard, how do I re-install it after booting up? I've done a check of the keyboards properties and it says it's functioning properly.

As with all troubleshooting, start at the physical layer and work your way up. Honestly, what it sounds like to me is either a problem with the ribbon that connects your keyboard to the motherboard, or else a bad port on the motherboard itself. The reason why the computer works fine when you plug in a secondary input device is because you're utilizing the device through a different port (likely one of your USB ports).

It is unlikely that the actual keyboard is the culprit. Furthermore, if it was an issue of spillage, it is logical to assume you would have many tertiary problems with the laptop beyond just input problems. The liquid would have seeped onto the motherboard and worked over some of the other copper points on the board itself.

It will reinstall itself, Windows has no ability to tell if the hardware is functioning properly, all it knows is if drivers are installed/functioning correctly

It might be what NHDave suggested or what Xanax suggested, both logical possibilities. If it is indeed a dirty, sticky keyboard then properly removing it from the laptop housing and letting it stay submerged overnight in a bucket filled with mild liquid soap/dish washer detergent and lukewarm water is what I would try.
Of course afterward, you would have to rinse it and then let it completely dry.

I believe it must have been the result of some sort of spill, it's working again, with no issues. If only all the other things that break in my life would mysteriously return to their working state given time.

Hi,

I am having the same issue. My kids spilled some tide detergent powder (can you believe it!) on the laptop keyboard. I cleaned up as much as possible after that. Now, the laptop works for a few minutes and randomly freezes. Both the keys and the mouse pad stops working. I have to reboot and it works fine for a few minutes and its back to freezing again.

What do I do? Pls help.

Thanks,
