    Set the brightness to 20% and wait a minute.

    I put the newest Bios on and even at 70% brightness noticed it. Not as frequent as when this issue first surfaced, when it appeared to be doing it every minute or so, but no less annoying for it.

    Suppose I'll have to rollback to 1.2.0 *again* :(

    Just out of curiosity I disabled the "Touch Function" in the BIOS. The flickering remains.

    Do I dare say it? I installed .14 and haven't *noticed* any flickering yet. I thought this was the silver bullet. I'm disappointed to read this hasn't worked for everyone. I'm on 20% right now and just staring and waiting.... (and squinting)....

    EDIT: Damn. There it is. Back with a vengeance. Took some time??? Now my flickering seems worse than before. Sigh...

    There's an option in the Intel HD Graphics Control Panel called "Panel Self-Refresh".

    If that is disabled, does it help people's screen flicker? I turned it off, and haven't noticed any flicker yet, but it might just be by chance.
