Screen turns off when unplugged
Hello all, Need your assistance with a recently noticed issue with my Latitude E5570, where the laptop screen turns off when I unplug it. The laptop continues running with no other perceivable problem (can access via TeamViewer to, for instance). If I plug it back, the screen remains off... I can get the screen back on with two options: 1. plug it and re-start it (sleep also works) or 2. plug it and allow it it trigger the screen suspension conditions (ie, no action for x minutes and activating the laptop again). The screen was working while unplugged before and, coincidence or not, my impression was that this started after laptop BIOS update to version 1.20.4 as recommended by Dell Command update app. Or some Windows update, but not sure... Reviewed power settings (found no issues) and even created a new power profile (activating ultra performance), but no luck. Preparing to use Window restore point option, but guess it will be a loss of time... Thank you for helping. -/- Windows 10 Pro; ver. 1809 buid 17763.593

I have had the same issue, installed the previous version and the problem was solved.
Dell will need to fix this

Had the same issue on my Latitude 5570, and can confirm that only a rollback to Bios v 1.19.3 was resolving it. I felt it was not just related to switch from AC to battery power but also being in a dock or not. For example, laptop screen stayed on while being in the doc while unplugging AC from dock. Sometimes screen stayed on even after undocking and randomly switched off after a few minutes. In any case, things are back to normal with the previous bios version 1.19.3. Stay away from v 1.20.4!

Go back to your restore point. If the problem goes away, you have your answer.

I am having the same issue with my Precision 3510 laptop. After I install the recommended BIOS update, my screen shuts off when I unplug the laptop from AC power. However, I cannot find where I can download the previous BIOS version. Can anyone point me in the right direction?

I found that I can use the Intel Control panel,
Power section, ( where the current setting is Balanced Mode & On Battery) -
Set Panel Self refresh = Off
I was able to unplug the laptop without screen shutting off.

Hi,
Decided not to change any setting in the Bios... Tried the other power settings solution and worked without issues. Try it as well:
Go to Intel Control panel,
Power section, ( where the current setting is Balanced Mode & On Battery) -
Set Panel Self refresh = Off

Thanks @jminasl so much for the tip about turning off panel self refresh in the Intel settings.
This issue was driving me nuts on my Dell Latitude E5470. Had tried older and latest BIOS versions. Latest updates, everything. Was even thinking it might be a faulty battery. All is well now.
