I have a Sony laptop and a girl spilled BEER on my keyboard and no the letter f runs across the screen and I can not get it to to stop sometimes. I have to use a second keyboard and I was wondering if anyone knows how to lock the main keyboard so that it is disabled but so that I can use my wireless one. Any help would be apprectiated thanksWireless will produce the worst results in this situation...grab a PS2 keyboard and see if this helps
On some laptops it is relatively easy to remove the keyboard...at any rate it NEEDS to be dried out thoroughly.
Warm NOT HOT blown air from a hair dryer works pretty well but you have to be patient.it has been dried out for a week. the girl didnt tell me about it so i actually have a usb keyboard plugged in but i just wanna disable the laptop keyboardThis is why i suggested a PS2 keyboard...it happens automatically.If you want to physically isolate the keyboard, remove it from the laptop and and you should be able to disconnect the ribbon cable attached to the underside. If you are not sure how to remove the keyboard - some laptop keyboards are very non-intuitive - see if you can download the service manual from the maker's website. But you may yet be able to save the keyboard.

The problem with any kind of spill is that although it may dry out, it leaves a residue which may be corrosive and may also re-absorb moisture when the air turns a bit humid, causing a return of the problem. To fix this, remove the keyboard from the laptop COMPLETELY and wash it - yes, I mean wash it - in distilled (demineralised) water, which you can buy from the supermarket. FOLLOW up with a good rinse in methylated spirits. Together these treatments will wash away any kind of residue. Drain the keyboard and let it dry thoroughly in a warm environment for at least several days.

If you remove the keyboard take care not to dislodge any of the keys; they can be extremely difficult to fit BACK again.Don't spend any more time with that girl.
If the laptop is under warranty, have Sony send out a new keyboard to you. Just don't tell them how the problem occurred.
