Vista - ps/2 driver issue plz help

Hi im new on the forums :P
im sittin on a zepto znote 6324w with vista home premium 64bit.
i recently spilled soda ( doh) into the laptop keyboard and the keyboard broke. only it still works but for instance when i am pressing s it presses a'æ and so on.
i plugged in an external usb keyboard and can use it easily as i am not a very mobile person nor am i having the pc located on my lab lol so no biggie. but the keyboard is randomly pushing buttons on its own, and now thats a pain in the but to have your pc constantly pressing s or page down or esc for that matter, when i press the buttons it stops, i could get it fixed at a retailer but that would cost me a months rent, and since i am studying i dont have that kind of money, so i tried first to disable the keyboard drivers without luck as the disable option is grayed out on keyboards, so i tried to remove the driver but it cant complete uninstall without reboot and it happens to reinstall on reboot as well -_- so i tried to disassemple the laptop on my own to directly pull out the plug from the motherboard, without luck, i had removed all the screws but at the end there was some screws to small for me and any screwdriver i could get my hands on, i even tried a screwdriver made for wrist watches but it was not small enough. so i tried fiddeling around with regedit on the ps/2 controller i8042prt.sys file only to meet the same impenetrable wall that is microsoft, so i started messing with system files and drivers for the keyboard with same result, the closest i got was when i got both my ps/2 and my usb disabled by deleting ( throught cmd ) i8042prt.sys and kbdclass.sys from my system32/drivers but avast, that was only a couple of minutes until windows found out what i had been doing and resurrected the files from the great beyond, :'( i'm normally on ubuntu but i am using this labtop for gaming and therefore using windows in. i find it hard to belive that the only way to do it is with either a saw or a retailer, there must be SOMEONe out there who can think of something i have not. please?

Carnal, welcome to the forums.

I would try disabling the KB itself from Device manager. This may or may not be what you tired earlier.

If it is, then Boot into BIOS, and mess with that. There might be a KB disable function.

yes that is what i tried earlier , the disable option is grayed out and the bios is no help forgot to mention that, is there a way to hack the bios? i could disable the ps/2 mouse ( touchpad ) but not the keyboard, further help would be greatly appreciated ^_^

Have you tried to remove the keyboard and wash it, then leave it to dry for a couple of days?
No I am not jokeing.
If this seems like to much hassle then take it to a repair shop for a quote, at a quess it should not cost more than £40.

its a laptop :\ and i cant get the keyboard out, and i am not going to wash the entire computer

I know it is a laptop.
Taking the keyboard out is not to hard for experianced users. This is why I said to take it to a shop if you were unsure.
The reason you are getting repeated keypresses is because the keys are stuck down by the drink being sticky. Taking apart the laptop and washing the keyboard may resolve this problem.

hmm , do you think any shop would do that apart from retailer? never thought of that

but even it was so i still find it hard to believe that there is absolutely no way what so ever to do it from windows, there must be a way!!!

Try this from an elevated CMD prompt:

SC CONFIG i8042prt START= DISABLED

Note the lack of space before the equals sign and the space just after it.

EDIT: But like Roy69 said, you might as well try a bit of distilled water on just the keyboard itself. Little to lose.

hey H2SO4 ... you... ROCK!!! thank you all for all the advice! problem solved with last entry NICE!!! i defeated Microsoft at last!! WIN WIN !!!
