Laptop Proc Upgrade

Ask the Doctor LogoI’m considering upgrading my laptop’s CPU but don’t know what to use as a replacement. My laptop is a Dell Latitude D820 with an Intel Core2 T5500. This CPU does not support virtualization, so I am looking to replace it with a CPU that does. How do I go about figuring out which CPUs go with my laptop motherboard? If I am going to void my (very expensive) warranty doing this, I want to be sure that I have the correct part.

Reset Laptop BIOS Password

Ask the Doctor LogoI have an HP Pavilion zv5001us laptop that is about six years old. It has a Phoenix BIOS, if I remember correctly. Whenever I try to access the BIOS, the computer prompts me for a password. I forgot the password and don’t know how to get around it. Thanks.
