Dell XPS 7590 laptops have an annoying tendency to overheat after going into sleep mode while plugged in. The laptop gets VERY hot and the fan runs full blast, for no apparent reason. I found a post on the Dell Community forum claiming the problem had something to do with the fingerprint scanner. It linked to another post explaining how to disable power management for the fingerprint driver.
To do so:
- Open Device Manager
- Under Biometric devices, open properties for Goodix fingerprint
- Open the Power management tab
- Uncheck Allow the computer to turn off this device to save power
It seems to have fixed the overheating issue for me.
