What does the Power Self-Refresh setting do? It's a great fix that is worth sacrificing something else for, but what exactly are we sacrificing? Just for clarity's sake. Cheers 🙂
I think the panel self refresh option makes screen refresh less often if there is no screen movement, so it consumes less power.
In my old Lenovo Yoga 2 Pro laptop panel self refresh option could reduce the power consumption by 1 watt, which is not a small thing...
New BIOS 1.3.0 out but it doesn't mention anything about keyboard fixes 😞
holy **bleep** is it me or has my xps just became snappier and more responsive? wow what a difference has it made... **bleep** this was the bloody fix we all needed all along... shame on u Dell
Strange you say this - I also thought my laptop got a bit faster after disabling panel self refresh, but I thought it must be me because that doesn't make sense.
Maybe it's some weird Intel GPU driver bug that causes keystrokes to be missed?
Hm, could be...
Whenever the panel self refresh was doing its thing (skipping a refresh frame), the keyboard would skip a key as well. And it would happen only if the key was pressed at the exact same moment when the display frame was skipped. Or something like that...
I suppose Dell engineers (and Intel's!) need to sort out those mixed up overlaps between the keyboard and the screen.
I've seen the panel refresh re-enable itself. I'm not sure under what circumstances, but it explains why my wife's laptop started missing keyclicks again.
