I have an Acer Spin SP513-52N. The CPU is an i5-8250U. Its advertised to have a base frequency of 1.80 GHz and the capability to reach 3.40 GHz. According to both task manager and Novabench, my CPU is running at 0.40 GHz! Doing simple tasks such as opening photos or chrome takes far too long. Is there a way to get to the 1.8 GHz speed? Is there someway to stay at the turbo speed (I would be willing to buy a laptop cooler if needed)? Additionally, is it possible to replace and upgrade the CPU? From what I can see, only the RAM is soldered in. If it is possible, what all would I need to keep in mind (temperature, PSU capability, socket size)? Thank you for any insight.
