Processor Intermittently Overheating in Sleep Mode
While in sleep and upon restart my Intal processor was overheating badly. I finally found Hibernate hidden under Advanced Power Settings and selected it with no sleep settings. The Settings selection seems to require Sleep when Hibernate is selected and vica versa, but advanced power settings allows one or the other so I selected Hibernate and no sleep. I believe that has solved my overheating problem. No more sleep!

1. Quick self-test procedure
Check Current Temperature
Download HWMonitor or Core Temp
Record temperature changes before and after sleep
Basic Thermal Maintenance
Clean dust from laptop air vents (compressed air)
Check if the cooling fan is functioning properly (listen to the sound)
2. System Settings Adjustment
Turn off “Fast Startup” (common cause)
Control Panel > Power Options > Select Power Button Functions
Click “Change settings that are currently unavailable”
Uncheck “Enable Fast Startup”
Save and reboot
Modify Sleep Mode
Administrator CMD Run:
cmd
powercfg /h off # Disable hibernation file (reduce wakeups)
Settings > System > Power > Other Power Settings
Select “Balance” Schedule > Change Schedule Settings
Set Sleep to “Never” (to test if it still overheats)
3. Advanced Troubleshooting
Check Wakeup Source
Administrator CMD run:
cmd
powercfg /lastwake
If it shows “unknown device”, update all drivers (especially chipset/USB)
Disable background activity
Settings > System > Power Mode > select “Optimal Energy Efficiency”
Task Manager > Startup Applications > Disable non-essential programs
4. Ultimate Solution
BIOS/UEFI Tweak
