Summary0001703: CPU Temperature not reported correctly after resume from sleep - v4.42
DescriptionOn resuming from sleep the CPU temperature is wrongly reported as approximately 30 degrees hotter than it actually is. This is the only temperature sensor which is effected. The temperature sensors for the motherboard, hard disk drive and the graphics card remain correct.

It may be an issue with the sensor chip as Everest 5.30 also reports the incorrect temperature after the resume from sleep. I verified the correct temperature by immediately closing the PC down after the resume and looking at the BIOS figures.

The configuration is:
Win 9x:NO 64Bit:NO GIVIO:NO SpeedFan:YES
Found nVidia GeForce 6200
Scanning ISA BUS at $0290...
SuperIO Chip=Winbond W83627UD-A
Winbond W83627HF (ID=$21) found on ISA at $290
Scanning Intel SMBUS at $0400...
Steps To ReproduceLet the system enter sleep mode and then reactivate it.
Additional InformationThis is not urgent for me as I was using SpeedFan to monitor the temperatures as part of an exercise to discover why the PC freezes during graphically intensive tasks. It does not appear to be temperature related. I thought you might find the information useful for bug fixing.

Thanks for your great work Alfredo.

According to what you say, this seems to be a BIOS issue. The BIOS is not properly configuring the hardware monitor chip. It might be that SpeedFan has an option in CONFIGURE / ADVANCED that might help you. Have a look at what changes in there before and after resume.
