CPU problem - Latitude E6530

OK. Something appears to be disabling SpeedStep from working and we need to figure out if it is at the BIOS / EC / board level or in Windows.

Did you try the other power plan options to see if one will get the CPU running more slowly? What happens if you lower the maximum CPU state in the power properties?

Would a live Linux work on this machine which would give the opportunity to check what happens in another operation system?

Guys, good news. It seems that the problem was at software level. After every clean install of windows 7, windows update was crashing (installing update and uninstalling them at every reboot) and overheating the system. Today, after a new reinstall, it worked immediately and the system temperature, after the loooong update process, is now at lower temperature. Anyway, at idle, the cpu is running between 46 and 54°C. What do you think? Are those normal temp?

Little OT: the notebook has a Crucial MX200 SSD with SED. If I enable the HDD password inside the BIOS option, the data is safe/encrypted?

 

Thanks for the update. I had suspected software more likely to be the problem than hardware.

Those temperatures are fine. The fan will be running slowly, if at all.

Even your maximum temperatures weren't exactly overheating: If the cooling system was keeping the temperatures below 80C then it is doing its job properly. I've had one notebook (I think it was the Lenovo T420s) which could get into the 90's C and start to throttle.
