Hello, I am trying to troubleshoot an HP Probook 650 g1 laptop issue. The fan constantly runs on high when powered in. This is regardless of os installed (Windows or linux), plugged in or on battery. The fan runs high even when booting into bios. This led me to believe there is a hardware problem
To remedy, I've tried:
- cleaning fan and vents
- removing, cleaning, and regreasing/reseating the heatsink
- turning off 'fan always on' in bios
- updating bios to newest version (2020)
- perform hp's hard reset to clear CMOS
- I've replaced the fan (because I thought the fan's sensor might be broken)
None of these have helped.
Now I've run out of ideas. Could it be a broken thermal sensor somewhere on the mb? (CPU temps are reported and do show fluctuations with load, so they seem to work properly...)
I'm not sure what else to try in order to problem solve this.
Open to any ideas you have.
