I recently bought a laptop and performed multiple stress tests on it. It was stable and thermal issues were no worries, until I ran the tests with the laptop plugged into the power supply.
It went from maxing 70s to hitting 100.
Can someone, please please please, explain to me why this happens?
If you're using windows, its might because of the difference configuration on the power setting when your laptop plugged in and not plugged in. Change the plugged in power setting in your laptop might help.
Windows sets all PCs to a “Balanced” power plan by default. But there are also “Power saver” and “High performance” plans. Your PC manufacturer may have even created their own power plans. What’s the difference between them all, and should you bother switching?
