I have a Dell studio 1555 laptop with Core2 Duo CPU & ATI Radeon 4500 series GPU. I run Windows 7.
Recently, when I boot my lappie, I foud it missing its display and I took it to a laptop service center. The technician told me that it was due to laptop heating and is a common fault. Then he made a hot air blow to GPU chips, and after cooling, the display came back. Then I told him to set fan speed to 100% to prevent over heating in future. Since there was no option for fan speed in BIOS, he made it manually.
Is this a good practice to set notebook fan speed to 100%? Will this setting prevent my notebook from overheating in future? Will I encounter with the same trouble again?
