I don't like the adaptive brightness, so I have it turned off.
When I turn on the tablet (V8P), it comes on at maximum brightness. When I go to the display setting, the slider is where I want it, but I have to tap it to get the brightness to the level where the slider is set.
This has been an intermittent problem for a year, but it's become more the rule than the exception lately.
Have had the same issue as well, with adaptive brightness set on. Although, curiously, distinct from your experience, mine actually has become fairly stable over the past few months, now that I think about it.
I have the same issue. When I wake the tablet up, it is frequently at full brightness. I just move the slider slightly and it returns to where it should be.
Should mention, I have the 7130 i5 and adaptive brightness is on. Display drivers (actually ALL drivers) are up to date.
I messed around with the advanced settings for the display brightness on the power options screen, and now it's .working again. I don't now why or what I actually did.
