HP Laptop problem

[Saleen836]

Recently the 'up' arrow on my keyboard arrow keys will not work if I am attempting to scroll back on a website,some days it will work fine other days it is hit & miss along wth it not working after working a few seconds previous, evrything else works perfectly, dodgy connection or shall I get my compressor out and give it a good blast of air to clear out any debris?

Yep blast to get rid of debris under the keyboard

I bought one of these 3 or 4 years ago:

I found the cans of compressed air hardly lasted very long and I was forever having to buy another couple of them.

Got round to firing up the compressor today and gave the laptop a good blast, hasn't made any difference to the 'up' arrow button so guess I will have to live with it.
