I have an HP Folio 13 ultrabook which is a great, lightweight computer. It has Windows 7 Pro.

 

The CPU runs hot and so the fan runs almost constantly. This affects my battery life and the noise, while not excessive, gets annoying.

 

There's no dust in the vents and I've installed the latest BIOS.

 

I did my homework and found out this is fairly common for the HP Folio 13, so I might be trying to fix something that is unfixable. 

 

But if there are any software utilities that will help it run cooler, suggestions on turning off background programs, etc. please send 'em my way. Thanks in advance for any help.

Hi, A couple of things come to mind.

 

Any warranty left?

Go to the control panel and check the power settings for the power profile You are using.

Bring up the Task Manager and look at the CPU use, The higher the CPU usage, the more heat it will generate.

Make sure that the Cooling Air Intakes are not blocked when using the laptop.

 

Did it always do this from new?

Are You sure the heatsink isn't clogged. That is the most common cause of Your problem. You say there is no dust in the vents, Any dust buildup will be internal and not visible.

 

Good Luck

Roger

Roger - No warranty left. Yes it's much more pronounced now than new. The air intakes are always uncovered when I'm using it.

 

I'll take it apart and look for dust on the heat sinks.

 

Thanks
