    Bummer. Usually monoprice has high quality at rock bottom prices. Sorry that didn't work out for you.

    monoprice service has been excellent the few times I've had to use it. If you asked I'd imagine they would replace it.

    Hey I'm wondering if anyone can help:
    When I press Fn+F3 and then choose "power off display" it turns off the screen (like its supposed to). Then I move the mouse or press a key and the screen comes back on. However, when I try to use Fn+F3 the second time (or anytime thereafter) I get to the screen and press "power off display", but nothing happens!!
    Its a bummer because this is one of my favorite features on any laptop ever. I have an ideapad s10 (netbook) and the quick screen off/screen on is possibly the best thing ever.
    Anyone else have this problem???

    I just noticed that this happens to me too... I'm pretty sure that it didn't before

    i just tried it and the same thing happens, i don't know why.

    edit: for some reason this is only happening for me when i have vlc running in a sandbox; i noticed that as i closed vlc the screen turned itself off in response to the f3 command that hadn't worked when i pressed it hours ago, sort of like it was queued up. i can recreate the behaviour by running it in the sandbox again. it's not the sandbox software itself, as it's been running the whole time, and it's not vlc, since it doesn't have this effect when run outside the sandbox. strange.

    Same story with my W520. Probably Lenovo power manager bug.

    A quick workaround is to create a desktop shortcut running "nircmd.exe monitor off" ( NirCmd - Windows command line tool ). You can assign a keyboard shortcut to it too.

    The BIOS can be applied to both UEFI and Legacy BIOS formats. Generally you shouldn't really need to update the BIOS unless you're after a specific feature or are having experiencing problems with your existing setup.
