I've ran into a running issue where my computer's (Aspire E 15 or E5-511-P0GC) has a performance drop in CPU frequency only when I plug in my computer's given charger that came with my computer.
I've already tried updating my BIOS to the newest version, performed computer resets and restarts, run anti-virus programs such as MalwareBytes and Avast, and checked my power settings (where everything was set on high performance no matter what).
I've recently bought the product about a month ago and have been trying to solve the problem for awhile now, so this is my first post in trying to get help.
What I've noticed occurs is a drop in CPU frequency from its typical 118% percent on high performance battery settings to a 22% still on the same high performance battery settings. I viewed this change in windows resource monitor when I unplug and plug in my charger.
So if anyone has any idea what may be the cause then I would love the help in trying to solve this issue.
(btw, I own other laptops and none of them have the same problem)
Those who think its a intel speedstep process then why would my laptop perform worse when I plug it in when speedstep is suppose to do the opposite to preserve the batteries life span. Plus I can't find a way to disable speedstep if my laptop has it as my BIOS is basically locked and there are no advance settings.
Edit: OS on my system is Windows 8.1
