s,d,g,h,m keys not working Help

I have a Old Acer Travelmate 604TER laptop and I updated it and Put on Windows XP , however now some keys are not working , would this be a keyboard Driver problem or something else , the computer says I have a
Standard 101/102-key or microsoft Natural PS/2 keyboard ( if need new driver where can I get one )
any suggestions would be great
thanks Mark

Its probably that you’re keys aren’t making full contact to send the signal. Try taking the keys off cleaning it.

Thanks mate , do you know how to remove Laptop Keys
Thanks Mark

Try: Google Search

with most (or all) keyboards you can lever out a single key with a small screwdriver (but take a photo of where each key goes, or make a note of the location) then to replace them just push them back into place (you’ll here a click when you’ve pushed enough)
