This is the downside to desktop P4 chips in laptops. The owners may not know that maintenance and cleaning is required. After a few years you may also have to get heatsinks checked or a fan replaced. I know many want it to need as much attention as a refrigerator, but these Pentium 4 based laptops need attention.
I am currently running a two-year old Dell Inspiron 1100 series laptop. From approximately six months ago, I have been noticing somewhat frequent overheating, or slowing down as I run more programs. It has an Intel Pentium 4 Processor and has 512 MB RAM. So I do think that my computer doesn't have the capabilites to run the programs. Do you think I would need to clean out my fan. I haven't cleaned out the fan or done anything with it since I have recieved the laptop, so does anyone know what to do. If I do need to clean out the laptop, does anyone know any specific method to cleaning it for the Inspiron 1100.
