My Laptop “Thermal Throttles” when removing the charger

A_S1997202A_S1997202 Posts: 4Member New User
i have an Acer Nitro 5 AN515-53H. 

With an intel Core i5-8300H processor, Nvidia GTX GeForce 1050, 16GB ddr4 2600mh/z RAM. 

I’ve been monitoring Heat and CPU useage using the XTU Intel Software. I undervolted down to -150V to reduce heat.

Whenever I plug out the charger cable - there is a thermal throttle spike. (Pic https://i.redd.it/eqsui7d7lij31.jpg

is this normal? Im concerned that I am receiving a thermal throttle from something like this. I just want a solution or answers whether if this normal or not.

    If you pull it out during gaming it will switch to the dedicated gpu which is not designed for gaming, so yes this would be normal. When gaming always charge battery to 100% before gaming and KEEP plugged into the power

    It happens when I’m not gaming as well. Even when the computer is idle. My battery settinhs are both on balance

    I didn't see your screenshot until now. From what I see this is absolutely normal. The short lived spike you are seeing is the result of the power cord being removed which is probably causing a surge, it is there and gone in an instant. Your temperatures and utilization of both CPU and GPU are absolutely normal and frankly unless I was getting consistent temps around 95 deg for the CPU, I wouldn't be undervolting because your dumbing down a good processor that is operating well within it's limits. In my opinion all looks normal to me.
