Hi Johann Mathew
Thank you for posting in Microsoft Community.
I understand the frustration you must be feeling, Johann. To address the overheating issue when your laptop is in sleep mode, here are some steps you can try:
Disable Modern Standby (If Applicable)
Open Command Prompt as Administrator and type:
powercfg /a
If Modern Standby is enabled, you may need to disable it via BIOS settings.
Change Sleep Mode to Hibernate
Go to Control Panel > Power Options > Choose what closing the lid does.
Set When I close the lid to Hibernate instead of Sleep.
Check Background Processes
Open Task Manager (Ctrl + Shift + Esc) and check if any processes are running while the laptop is in sleep mode.
Disable unnecessary startup programs under Startup tab.
Update Drivers & BIOS
Go to Device Manager (Win + X > Device Manager).
Expand System devices and update Intel Management Engine Interface.
Check your laptop manufacturer’s website for BIOS updates.
Check for Windows Updates
Go to Settings > Windows Update and install any pending updates.
Perform Repair in-place upgrade: This will reinstall your Operating System and will keep your files and apps. This will take some time depending on the computer performance and internet speed. You can follow the steps from this link: How to perform repair upgrade in Windows 11 - Microsoft Community
Please let me know if this helps.
