Solve : Slow laptop when plugged in but not on battery?

Answer» <html><body><p>I have an Acer Aspire ES1-512 x64-based PC (laptop) with Windows 8.1 6.3.9600 N/A <a href="https://interviewquestions.tuteehub.com/tag/build-403683" style="font-weight:bold;" target="_blank" title="Click to know more about BUILD">BUILD</a> 9600.  When it is using the battery (not plugged in) it is fine, but recently it began to behave very, very slowly whenever I plugged it in (while charging or NOT charging the battery).  Is there a setting I inadvertently set to make this happen?  Please <a href="https://interviewquestions.tuteehub.com/tag/help-239643" style="font-weight:bold;" target="_blank" title="Click to know more about HELP">HELP</a>!  It's running about 10 times more slowly when it's plugged in.  <a href="https://interviewquestions.tuteehub.com/tag/thank-1731949" style="font-weight:bold;" target="_blank" title="Click to know more about THANK">THANK</a> you.<br/>Wild <a href="https://interviewquestions.tuteehub.com/tag/guess-1013936" style="font-weight:bold;" target="_blank" title="Click to know more about GUESS">GUESS</a>, but based on a real happenstance.<br/>Your  power mains have a high level of <a href="https://interviewquestions.tuteehub.com/tag/noise-13653" style="font-weight:bold;" target="_blank" title="Click to know more about NOISE">NOISE</a> interference with your laptop.<br/>Or, the charger is going bad and feeds trashy power to the system.<br/>Last thing you might find is  -------  T<em>he battery!</em><br/><br/>Does it run without the battery?<br/><br/>Actually, after I posted I went home and looked at all my settings, and indeed, I finally came across one setting which opted for maximum speed/spare the disk (which minimizes speed).   When using the battery, it opted for maximum speed, but when it was plugged in, it opted for minimum speed.  I reset it and it immediately began to behave properly again.  I have no idea how that happened, I certainly did not do it knowingly.  Someone may have hacked into my system.</p></body></html>
