That's my first inclination, especially without information like model number and such. Additionally the Pentium 4M is what you need for a laptop, you cannot use a desktop CPU. | Report abuse ItzReactly April 23, 2012 5:07:15 AM my computer specs is Compaq Presario CQ62 CPU: Intel Celeron 900 @ 2.2 Ghz RAM: 3 GB | Report abuse sk1939 CPUs Expert April 23, 2012 5:25:37 AM The good new is that the laptop has a modular socket, rather than soldered chip. The bad news is that you are limited to Pentium 4-M processors, and even then you run the risk of overwhelming the laptops cooling system because it was not designed for any other processor.
