Brightness automatically goes down to zero

[the-gaurav-paul]

I have been facing an issue recently where the brightness of the screen drops to zero and even if I raise it, it still keeps reducing until the bar touches to zero.
I have tried updating windows, display drivers, monitor related drivers all are up to date.

Hi @the-gaurav-paul,

Welcome to the HP Support Community

I understand you are facing a disaply-related issue with your HP 15.6 Inch Laptop PC 15-E2000 (2K3D8AV). Not to worry I will help you to get a resolution to resolve the issue.

Adaptive brightness might have been enabled and that might be causing this issue: Your screen changes from very bright to dark based on the light coming in through its sensors. This helps to prevent your phone from being overly bright and unnecessarily wasting battery life.
This same technology is available in certain computers. Microsoft first introduced auto-brightness in Windows 8 computers but Windows 10 PCs may also include this feature.

Disable auto-brightness

1. Go to the Start menu and open the Control Panel

2. In the Control Panel, go to Power Options

3. After the Power Options window pops up, click on Change Plan Settings to look at your current power plan

4. Choose the option to Change advanced power settings located at the bottom of the window. This will open up the Advanced Power Options window

5. Scroll down to the Display option. Expand it to show the Adaptive Brightness option

6. Choose to turn on or turn off this feature for both when it’s on battery power and when the computer is plugged in

7. Save the settings through clicking Apply and then OK

If you don’t find an Adaptive Display setting, your device might not have a built-in ambient light sensor.

8. If you followed the instructions but the adaptive brightness didn’t change your auto-brightness setting, you’ll need to turn off the Sensor Monitoring service by pressing Win + R and typing services.msc. Then press Enter

9. In the services window, click on the Sensor Monitoring Service which will lead to the service settings window

10. Click Stop and select Disabled from the drop-down menu found next to the Startup type

11. Save changes by clicking OK

Hope this helps! Keep me posted.
