I have a little problem with my computer's (Samsung N145 Plus) keyboard. Recently the down-key (no PgDn) have started to act weird. On most of the pages instead of going down little by little it goes all the way down the page. I only press it once. Sometimes it also "jams" for a little while, not letting me go up with the up-key. I've tried rebooting the computer but it didn't do any good.
It doesn't feel like there's anything stuck underneath it. I really don't know what to do and it's starting to piss me off really bad.
If you have any ideas please do throw them out and do ask if there's something more I can fill you in with.
