I have a Gateway P-7805u notebook that’s been running hot, slow and noisy for a while now. I didn’t think anything of it until I tried to play Battlefield 2, a game it should have handled with ease, and the system slowed to a crawl.
After fiddling with other solutions that did nothing, it struck me the system was getting so hot it had to slow down the processors to generate less heat. Getting to the fans so I could check them for dust was not as easy as on my previous laptop, but I eventually found two great guides to walk me through the process of taking everything apart:
- Basic: http://www.insidemylaptop.com/taking-apart-gateway-p-series-laptop/
- Detailed: http://forum.notebookreview.com/gateway-emachines/382408-gateway-fx-disassembly-guide-covers-all-17in-fx-notebooks.html
Sure enough, even though we don’t smoke or have pets there was a lot of dust clogging the cooling system. Once I got that cleaned out the system ran much cooler, the noise level dropped off because the fans didn’t have to run continually, and best of all Battlefield 2 runs like a well-oiled machine, just the way it should.
Even if dust isn’t your issue, the guides above are detailed enough to walk you through replacing just about anything on your system, including the screen and the fans. Check them out.
