I have an hp pavilion dv5-1150us laptop and was wondering if i could upgrade my processor and if so how much would it cost to have it upgraded
Since Intel doesn't do direct sales, you'd have to
1) Check which processors are supported on that laptop (probably at HP's website), and
2) Buy from a vendor.
It'd probaby be fastest to purchase the replacement from HP as well, to avoid any kind of warranty issues.
