Hi @Tay11a-1,

Welcome to the HP Support Community.
 

Thank you for posting your query. I will be glad to help you.

We understand you're unable to adjust the brightness on your HP 15.6-inch Laptop PC 15-e2000 (2J4V9AV) — both the keyboard shortcuts and the brightness slider in Settings > Display are not working or missing. This issue typically points to a display driver issue or missing power/graphics settings in Windows.
 

Let's try a few steps to resolve the issue.

1: Reinstall Display Drivers

1. Press Windows + X > choose Device Manager.
2. Expand Display adapters.
3. Right-click on your graphics adapter (e.g., Intel UHD Graphics or AMD Radeon) and choose Uninstall device.
4. Check the box for “Delete the driver software for this device”, then click Uninstall.
5. Restart your PC.

Upon reboot, Windows will automatically reinstall a basic display driver. If the brightness slider returns, you're halfway there.

2: Install the Latest Graphics Driver from HP

1. Visit the HP support page:
   🔗 HP 15.6 inch Laptop PC 15-e2000 (2J4V9AV) Software and Driver Downloads | HP® Support
2. Under the Driver-Graphics section, download and install the latest available:
   • Intel Graphics Driver
   • Or AMD Radeon Software, depending on your model
3. Restart the laptop once installed.

3: Install or update the Microsoft Basic Display Adapter (if needed)

If your GPU drivers don’t restore brightness control, manually switch:

1. Go to Device Manager > Display adapters.
2. Right-click > Update driver > Browse my computer > Let me pick.
3. Select Microsoft Basic Display Adapter from the list.
4. Apply and restart.

4: Enable Generic PnP Monitor

1. Open Device Manager.
2. Expand Monitors.
3. If you see Generic PnP Monitor:
   • Right-click > Enable (if it's disabled).
   • Or right-click > Uninstall device > then restart.

🟢 This often restores the missing brightness slider in Settings > Display.

I hope this helps.

Take care and have a good day.
