Solved Problem with Chassis1 Fan after sleep
#1
After resume from sleep only Chassis1 Fan is zero. After restart HWiNFO64 Chassis1 Fan is Ok. If I use AIDA64 Extreme Edition I don't have this problem.

Motherboard - ASUS P5K-VM
OS - Windows 7 SP1, 64 bit
HWiNFO - HWiNFO64

This is because the BIOS doesn't configure the fan settings properly, so HWiNFO needs to do that.
It does set them during start, but it seems that after resuming from suspend the settings are lost again.
I'll fix this in the next build, so HWiNFO will reconfigure them after resume as well.

The release 1770 worked normal after resuming from suspend.
But the release 1775 work with zero fan after resuming from suspend again.

I haven't performed any changes in this area between build 1770-1775.
Can you please attach a new debug file with the suspend-resume sequence when fan drops to 0 ?

According to that dump, all seems OK after resume. Does it behave exactly as before - before suspend does Chassis fan 1 show a speed and after resume it's 0 ?

Could you please create a Debug File including following scenario: Perform a Suspend / Resume sequence (CPU fan=0) and then close HWiNFO sensors and open again.

Is this Debug File create after the exact sequence I described before? Did it show the correct fan speed after this sequence?

If you run HWiNFO in Sensor-only mode, then disable it.
Then please follow the procedure as before and attach a new debug file.

I have added additional information into the debug output to help me better locate this problem.
Please run this build: http://www.hwinfo.com/beta/hw64_411_1826.zip
and create a new debug file capturing the suspend/resume sequence.

I have attach the debug file.
The sequence is start, suspend, resume, quit, start.

Please do not perform the quit+start sequence, just do the suspend/resume and attach the resulting debug file.

I have attach the debug file.
The sequence is start, suspend, resume, quit (Hwinfo process lock the debug file without quit).

Thanks for the new dump and your patience. It shows me now where the problem might be, so I'm working on a fix.
But just to be sure, could you please repeat the previous process 3 times and attach 3 debug files from each cycle? I need to verify if there's some random behavior to fan control logic, or if the results show always the same schema.
