I know this sounds picky, but I would like the screen brightness to stay at one level until I change it, regardless of whether I'm running off battery or AC power.
The problem I have is that I often run the laptop in the vehicle (passenger, of course!) and to do this I plug it into an inverter. The inverter occasionally drops and this results in a the laptop switching back to battery power for just a second or two and of course, when this happens the brightness changes. This means that I'm constantly having the re-adjust the brightness settings.
Oh well, looks like my only option may be to try and fix the inverter issue.
Thanks. Great form by the way!
