Toshiba Keys Not Working

Hello,

A few of my keys have stopped working on the keyboard of my toshiba laptop after a dreaded water spill. When i spilled the water the laptop was off, and i immediately turned the laptop over and left it to dry. When I turned it back on, initially the A key didn't work and probably a lot of others but the A was the only key I noticed as my password has an A in it. A few days later when i turned it on the A key must have dried out more and it had started to work, allowing me to log on. However, it has been 5 days since i spilled the (small amount of) water on the keyboard and these keys do not work [Q, X, WIN, Fn, Ctrl]

The X key works if i hold the key down for a long while, but the others do not seem to do this. Obviously the kb is not trashed as it still works for most keys and the A key started working again. Does anyone have any advice on how i can take apart and clean or make sure it is dry? Or what has caused the keys to not work after they are dry, i have taken a few caps off and the toshiba laptop looks pretty water proof (lots of rubber caps, and nothing looking rustable/corrosive-able) I could post pictures if needed or has anyone had experience with Tosh keyboards who could help me. Replacing is a last resort as i priced up a new keyboard online at £50~. That doesn't seem worth it

Any help appreciated.

unfortunately the only answer I know of is to replace it.

With a desktop keyboard you can remove the circuit board and just run the keyboard through the dishwasher (no soap, dont dry). If you can get the circuit board off the laptop keyboard this may work, though I dont know if that is possible.

Shame .

Is £50 the going rate for a keyboard then, do you know? As a student, i have a passion against spending money, and for 2 missing letter keys, i'd rather struggle with the on screen keyboard
