Dell 7567 lags/FPS drop while plugged in but runs perfect on battery

Please verify the System Setup(BIOS) version on the system. Type msinfo32 onto [Cortana] search box, and then stroll down to BIOS Version / Date. You should see it.

In the meantime, you could check and change the power plan in Power Options.  Please type Settings onto [Cortana] search box,  click System, Power & Sleep, Additional Power Settings and select Create A Power Plan.

hi LSUFAN51,

MY BIOS version is: BIOS Version/Date: Dell Inc. 1.4.0, 11-12-2017.

And the power plan settings I have tried. I tried editing the balanced power plan. Made sure all settings are same for battery and power. I still had 0 difference.

Also, I ran the Dell diagnostics (Stress Tests and Full Diagnostics). All tests came out ok. Hence, hardware is fine.

hi,

Thanks again for the revert. However all the drivers etc. are latest. I keep my PC up to date.

The performance was fine since the purchase. It has deteriorated suddenly off late.
