The laptop is currently running a Celeron M 400 processor with 2 GB of ram(max capacity) under windows 7. I run 3-4 programs at a time on it and it lags. I would like to upgrade the CPU. I was wondering if an Intel Core 2 Duo t5600 would be compatible with the system. I tried looking up information for it from the manufacturers website but found conflicting information -they were not sure if the Bios would support or if the laptop would have adequate cooling. I am looking for help on this matter from the experts. If said processor is not supported could you also recommend something else I could purchase off the used market in its place (ebay Canada will be most likely avenue).
I also realize it is fairly old and I should probably buy a new computer but I can't afford one right now. I am of average experienced when it comes to computers but have rebuilt some systems in the past. I plan to do the upgrade very cautiously .
