Hello, I'm using the Dell inspiron 3542 i5 4210u GT 820m b21w81c model, but when using my computer on the battery, the screen flickers strangely, as if the brightness is increasing and decreasing 100 times per second, when I look at the voltage value from my new hw monitor, I see around 15v, I updated all the drivers and reinstalled but still this problem i am alive can you help me

Does the same flicker show on the screen during the built-in self test (hold the D key through powerup to access)?

I did all of them, there is no problem in the lcd and it did not flicker and when I did the diagnostic test, there was no problem again, now I think it's software.

Fix your display driver
If Windows Update recently made updates to your device, roll back your display driver. Otherwise, try updating or uninstalling your display driver to fix the flickering or scrambling problem. In the search box on the taskbar, enter device manager, and then select it from the list of results.
