(Possibly sometime) after upgrading to Win 10, my HP DV5-2144ca Laptop became sluggish. Slow browsing experience, YouTube video lagging...
In TaskManager I've noticed that CPU speed is limited to 0.8 GHz and CPU utilization tops around 33%.
Laptop is connected to AC 99% of the time
After a fresh restart (ON/OFF) everything works fine (speed fluctuates between 0.77 to 2.40 GHz) , then for no apparent reason CPU slows down to 0.8 GHz.
I've run Open Hardware Monitor the CPU temps seems OK around 55 to 65 oC
- I tried "high performance" power option
- I even put the laptop in the fridge :-) before turning it on. But the problem reappears even with CPU temp near 35 oC
- There is no BIOS option for turning AMD POWERNOW! off.
I don't expect any help from HP tech, since this is a 6 years old Laptop. I don't want to buy another computer. This one works fine (when CPU speed is not limited).
Is there a solution ?
I was going to rant but found this post that summarizes everything I wanted to say.
