Could anyone tell me how or where I could find info to remove my keyboard on a HP Pavilion ZD8220us Laptop? I want to clean out my heat sync and processor for possible dust build-up,or airflow obstruction, which is causing my laptop to shutdown after a few hours of use. I’ve scanned my hard disc already for possible file damage. So my guess is that my laptop is overheating? I had my laptop for almost two years and again, I believe there may be alot of dust inside of my laptop causing it to overheat and shutdown intermittently? Thanks, Art
