I've gotten a new T480 as my primary work laptop. After getting past the initial setup of the machine, including updating drivers, firmware and BIOS, almost everything is running quite well. The one thing that I noticed which is odd is that while I am in a meeting with the system not plugged in and running off of the batteries, the screen brightness is adjusting itself. I don't understand why this is happening, as I am active on the system for most of the time, so it would not appear to be a power setting.
Has anyone else seen this? It's happening just about anytime I am unplugged and running off of the batteries. As I was typing this subject in, the suggestions seemed to indicate that this is also happening with other systems. I don't have the time to go look at those threads to see if it has been addressed there unfortunately, so I am asking the question here.
Hopefully this is just a driver or a BIOS fix that can be implemented with minimal disruption.
Thanks in advance for any additional information that is provided!
