Inconsistent Fan Grinding/Buzzing
Hi
I've been getting a temporary grinding or buzzing noise for months--pretty sure it's from the fan. It normally commences on start, continues for a few minutes (2-5) then stops. Occasionally it will start up again and a tap on the laptop--top/center often stops it.
I've tried everything I can think of: Compressed air, updated BIOS, opened it up--fan spins quietly and apparently unrestricted. Diagnostics show no problems.
Would like to solve--when it's grinding it's loud and I'm suspecting problems down the road.
As I type this, she's absoltely silent!
Any ideas out there?
