I accidently dripped a drop of water onto my keyboard. Over a period of 3 months 4 keys on my keyboard would initially work but as the laptop got upto 90 deg celsius they would fail. I changed the keyboard, the problem was not rectified, 2 months later the keys now permanently do not work. I have since used measures to reduce heat to the cpu & motherboard and got it down to 60-70 celsius but to no avail.
Could it be the motherboard damaged? any hints or help would be great, the laptop is only 14 months old.
