m15 r2, low performance when plugged in

Question

Was working completely fine last night until now, browsing is completely laggy as well as playing games. When not charging, everything runs perfectly fine and able to browse at ease. I reinstall my graphics driver, move the plug to a new outlet, check processor state, reinstall OC control and the problem still persist.

Since the computer was working fine last night, run the System Restore tool to takes your computer back to an earlier point in time such as when computer ran normally.

System Restore won’t affect your personal files, but it will remove apps, drivers, and updates installed after the restore point was made.
