Hi BeyondAJ,
Welcome to Sony Community!
We're sorry to hear about the issue that you're having with your laptop. May I know what is the current operating system of your device? Do you still remember when did you first notice about the issue?
Kindly perform the following steps and check if the over heating is still observed.
Take note that each step may resolve the issue. Try to replicate first before proceeding to the next step.
1. Reset the BIOS to default setting.
2. Boot to Safe Mode .
3. Perform a clean boot.
4. System Restore to an earlier date.
Regards,
Jen
