A really nice laptop / convertible. I'm running Vista Business.
But sometimes when I was scrolling, especially with the job dial in the side, the screen would flicker a bit. Granted, I have it cranked up to max brightness (and an extended battery to compensate)
Updating the drivers did not fix the problem.
The fix I found was to tweak the power saving mode of the video graphics; the flickering seems to be caused by something to do with the power saving mode. You only have to crank it up one or two notches, not all the way, to fix the problem, so just experiment a bit.
Right click on the Desktop (or tap and hold) -> Graphics settings (or something like that) -> you want the Intel branded control panel
On that blue and white control window there are 4 tabs on the left. I think it's the tab second down. Then on the bottom right corner is a button for Power Settings. A bit hard to find.
Try adjusting the slider to one click down from Best Performance / Worst Battery.
And a theory:
I get this bug has been around for a while, but previous laptops used thin CF tubes for backlighting, which I suspect mask the flickering a bit. But the HP is one of the new LED backlit displays, and LEDs are very flicker prone (or, to split hairs, will more accurately mirror rapid electrical fluctuations)
