Random screen blink, sometimes black for several seconds, reloads windows and tabs

2020-12-07, 1:32 AM

This is driving me crazy. I feel like the aliens or the CIA or the mafia are plugging/unplugging into my computer which causes the laptop screen to blink randomly every few seconds or minutes or hours. It's only on the laptop screen, not any external monitors.

Sometimes it'll go black for several seconds though, and when it comes back, my windows refresh and sometimes tabs reload (and sometimes I'll see all the tabs disappear and start opening and reloading).

I've tried restarting, Shift+Shutdown, re-installing display drivers, Safe Mode... I'm not sure how to find out what's causing it.

Which dock? Have your tried shutting off notebook screen and seeing if this happens on the externals when that's done? I see this happen on certain webpages only.

Which dock? I didn't mention a dock. The screen blink happens only on the laptop screen.

The notebook screen shuts off when I close the lid, which sleeps or hibernates Windows, and when doing a restart or shutdown... which I mentioned I've already tried.

I don't know how to just shut the screen off otherwise. Do you?

The problem only happens for you on certain web pages? It happens to mine regardless of what I'm doing.

If the laptop is connected to external monitors, the laptop screen will still randomly blink or go black for several seconds. When it goes black for several seconds, it'll refresh windows and tabs, sometimes reload them.

Please somebody give me something useful to look at or troubleshoot so I can at least see what under the hood is happening when this happens.

Look under "Power Plan Settings" - do a search for that and adjust.  Whatever plan you have,

you can set the screen to blank after a specific time without shutting the lid.  When on battery

or on AC.

I set up the power plan when I got the laptop, even after I noticed screen blink (which happens often). The power plan is exactly what I want. I've adjusted it a few times over the weeks, yet the screen blink is the same. The screen blink is not coinciding with power plan settings, and there's no setting for when to have the screen blink (which is an undesirable behavior anyway), and if there was, I don't know why anyone would set it to "random".

Are you sure you understand this issue?

I need some real solutions here.

Oh OK, another random thought.  Have you updated the NVidia driver?  Mine got that update as soon as I

installed Windows.  I have not see this problem either before or after the update.

Dear customer,

There is the active workaround description there, I hope it will work on your case.

I already tried updating driver. Device Manager says it's up to date and there's no new Windows Update.

Dear customer,

the issue described there was caused by WWAN driver’s FirmwareSwitchService triggered the display flickering issue even system has no WWAN devcie installed.
In case your P15 doesn't have WWAN device but have FirmwareSwitchService running by checking Task Manager -> Services, you can try to disable that service once.
