I have a Lenovo G510 as my regular laptop, running Win10 Anniversary edition. It has dual core i5 CPU at 2.5 Ghz, SSD disk and 16 GB Ram. For the majority of the time it behaves perfectly for what I need, however a couple of times an hour it'll go-slow. By this, I mean the responsiveness takes a nosedive - however ~60 seconds later all will be fine again.
During a go-slow, if I look in task manager I see that the CPU is maxing out at 32%, like so:
When it decides to work again it returns to the normal 'peaks and troughs' that I'd normally see in Task Manager.
There are no processes hammering the system, so why can it not use more than 32% of the CPU for these periods?
Thanks for any suggestions!
EDIT: I do not believe that this is the same issue as the Lenovo stays at minimum clock speed question. In that case the CPU was throttled due to power management settings and the battery being unplugged. Here the battery is in place (even though I'm plugged in) and the power settings are on max-performance. Thanks!
EDIT2: I've just noticed that Task Manager reports that my clock speed has reduced to 0.78 Ghz during the go-slow (as can be seen in the screenshot above). Normally it reports it to be 2.48Ghz.
