Just had my Dell Latitude D830 cleaned of dust with new gunk applied to the CPU. So now it's running well, but I never hear the fan. The CPU is running at 47 degrees Celsius and the fan is NOT running. Is that normal? Thanks.
I have a Satellite Pro 4340 (also known as 4300) and have very recently found its maintenance manual on the web. It calls for a diagnostics disk but does not explain what that is. Do you know what it is and where to find it? Thanks.
