Unexpected shutdowns: it isHP ProBook 4520s unexpected shutdowns due to overheating?

Hello,

I got a probook 4520s.

Sometimes fans spin very high and the notebook shutdown. Then sometimes I cannot power up it again immediately.

Please note that this can happen also in bios or with a linux live cd and so it is not windows related.

I supposed that overheating was due to dirty fan. I opened it but fans are a bit dirty but not so much.

I have also another problem. I was reinstalling windows from scratch using recovery partition. It powered off in the middle of reinstalling.

Now I would like to reinstall again but recovery partition has disappeared.

Thanks in advance for help,

Mario
