Brightness issue

[chripou]

Hi, 

Since a couple weeks, every time I wake up my computer, the brightness is 0%. 

I have to manually adjust it to my preference each time.

Any idea?

Don’t worry, I assure you I will try my best to get this sorted.

In order that I may provide you with an accurate solution, I will need a few more details.

• What is the exact model for your computer?

Meanwhile, I recommend you update the BIOS and the graphics driver from the below link and check if it helps.

If you continue facing the issue, I recommend you download and install HP support assistant from the below link and install all the updates.

5. Select the box next to any updates you want to install, and then click Download and install.

6. Perform any other update management actions as needed.

   • Postpone an update: Click Remind me, and then select a time preference.

   • Delete an available update: Click the Delete icon  to remove the update from the list and record it in the action log.
