My Mother has an HP Pavilion 23 running an AMD processor. It’s running win10. When the computer comes on, most of the time it comes on with the screen so dim I can barely make out what’s on it. I also noticed there is no brightness control in the settings for Windows anywhere. It’s really annoying. I figure there may be a piece of HP proprietary software somewhere messing it up but I can’t find it. I updated the video driver but that didn’t help. I just can’t figure this one out.
