No Display Adapter in Device Manager

HP Recommended
HP Notebook - 15-ra015ni

My laptop screen is dim but recently it has gotten really dim and the F2 and F3 buttons do not work to increase/decrease the brightness. I searched up what to do and they said to check my display adapter in my device manager. Went there and could not find any display adapter. Please help.

Product name: HP Notebook - 15-ra015ni

Product Number: 4UT16EA

 

Thank you.

Thank you for posting on the HP Support Community.
 

Don't worry as I'll be glad to help, I understand that the HP laptop display entry is missing in the Device Manager,  to provide an accurate resolution, I need a few more details:

  • Did this happen after a recent window or software update?
  • Did you make any changes to the settings of your PC prior to the issue?
  • When was the last time it worked fine?

While you respond to that, let's try these steps: 

Hard Reset: Follow steps from the link: https://hp.care/2GnkMa8. (Refer to the removable and sealed battery)
BIOS default:(do not skip any troubleshooting steps even if you feel steps are repeating)

  1. Turn off the computer and wait five seconds.
  2. Press the Power button to start the computer and repeatedly press the F10 key to enter the BIOS setup menu.
  3. On the BIOS Setup screen, press F9 to select and load the BIOS Setup Default settings.
  4. Press F10 to Save and    Exit.
  5. Use the arrow keys to select Yes, then press Enter when asked Exit Saving Changes?
  6. Follow the prompts to restart your computer. 

Hope this helps! Keep me posted for further assistance.

Good day,

Thank you so much for being willing to help. I have tried both solutions and both were unsuccessful. To answer your questions, it happened before a recent software update and i have made no known settings to my PC prior to the change. If I recall correctly, the last time it worked properly was the 25th of September (one day prior to the initial message).

 

Yours truly,
Demi
