Week ago an issue sort of crippled my notebook. All of a sudden whilst in Chrome browser, V SCR Bar would go to bottom of the page on its own. No updates etc was noted. Checked and did h/w trubleshooting etc. did not find the cause. Note this happens to any application, be it MS Word, or anyy Browsers.
Checked for stuck button, didnt find any so used a program to testkb. found out that pg dn button was simulatously being pressed on its own when doing kb test. checked and cleaned button but no luck. issue still happens. Laptop is nearly 1 yr 3 months old, and first HP laptop that I got. Hoping to fix . HELP.
