louder fan after sleep mode

Hi. I have a question.

Does your dv4t's or dv5t's fan run louder after you put your laptop to the sleep mode and "wake up" yours back?

Actually, kevinf asked me the same question weeks ago... but at that time, I didn't have to put my dv4t to the sleep mode... Now... it's very annoying.

I enabled "Fan Always On" in the BIOS because disabling the option makes the fan run louder!!!!

So, before putting my dv4t to the sleep mode, the fan runs at the lowest speed constantly unless I stress the CPU or GPU to a certain point. And, even if the fan runs faster and louder after I stress the CPU or GPU, it goes back to its normal speed after the CPU temperature drops back to about 42 degrees Celsius.

However, after waking up the notebook from the sleep mode, the fan runs at the loud, medium speed constantly until the CPU temperature reaches something like 31~33 degrees Celsius. (I'm not talking about the core tempreatures.) That's almost impossible if you are running any kind of program.

The fan keeps spinning at the same speed until I turn off the computer completely or with the hibernation mode.

 

I'm guessing your version of bios is F.04, if they are try the just released bios F.12, there both on this page.

And if you are running the newer bios try rolling back to the last version, maybe future versions will address that issue. I don't know what model you have of the dv4t but both use the same bios.
