Avoid stuck keys messing with boot

The answers to this is probably no, but I'll try anyway

So I know a fool who spilt some stuff all over their laptop keyboard and the keys can be a bit sticky, especially the F keys. Now, one time in ten, on boot, it goes crazy at the bios screen with one constant beep that will not stop until you force the power down with the on button. Simply swiping all over the keys in a random fashion usually allows it to boot next time.

Is there any way to avoid this happeneing without totally disabling the keyboard as he operates a dual boot system and need to be able to select the correct OS

Silly question, isn't it

Not silly at all...
Many laptop replacement keyboards are actually reasonably priced though and that would be my suggestion.

I didnt include that line, without replacing the keyboard :P

Thanks for the suggestion anyhow

Keys not physically removable, while powered off, to clean individually?
Can try prying one off very gently, if able clean them all and the surface under them, varies greatly.

Other than that, I'd add a wireless or USB keyboard.

Either clean or replace, no other option. External keyboard might not help much unless you disable the laptop keyboard which does not seem to be possible.

I've heard of this being done with good results. Disassemble what you have to, to remove the keyboard. Then give it a good gentle rinse in warm to hot water. Then dry it with a hair dryer or set it aside in a warm dry place for a day or two to dry out. Then once your sure its completely dry put it back in and cross your fingers.

I've taken regular desktop keyboards and rinsed them in the sink with warm water. Then let them dry out in the sun for a day or two. They were never any worse and often better as far as sticky keys go. Still I would class this as one of those use at your own risk type of adventures.
