Whenever you spill something on a laptop OR on anything with keys you remove the keys then clean it with a cotton swab. But since you already cleaned it let it dry for a few hours and if it still doesn't work replace it. Hope my answer helps, Good Luck!
I spilled coke on the corner of my laptop, like the arrow keys and end button. The keys aren't sticky but the down arrow won't work? I cleaned it off, what do I do now?
Well I don't think self-repair can go anywhere. I mean, coke contains sugar and other ingredients. So if it was water that messed it up, that would just be temporary, if water isn't the only cause, then I would suggest waiting for at least a day(?) for it to dry and test it first, if it still messed up, then you could go to cmputer repair shops. Of course sadly, that would come with a price.
Wait till your mum finds out! Hehe 8) oh and clean between the keyboards..! And take the keyboard our or buy a new one! XD
