  1. The fn + f5 combination is not functional on my Acer Aspire One AOA150. This combination is used to toggle to an external monitor using a VGA cord. How can I turn it back on?

    Did it ever work before? You know you have to press it more than once to toggle between the two.

    If it worked before, what has changed since last it worked?

    I would also try to remove the power adapter and battery may be even the CMOS battery then try again before we get in to software.

    Certain Notebooks don't like to be connected to "big Screen LCDs or TVs" and after sometime they cause hardware failure in the Notebook, Netbook, mini notebook or whatever you call Acer Aspire One series. This used to happen with certain Samsung LCDs, don't remember but I think it was larger than 21" or something!

    It has worked before, but I have not done anything major since then. It has worked with my external monitor before, and it is not a big screen tv.

    I would do BIOS reset as posted above load defaults and try one more time.

    You might want to try turning the monitor OFF, disconnect it from Aspire one and the power outlet, then power adapter and the battery from Aspire one for a minute, reconnect the battery and adapter then the monitor and try again.

    When the adapter and the battery are disconnected, make sure there are no powered USB devices and Ethernet cables from a router connected to the Aspire One.

    Don't recall if Aspire One has the reset button under the system similar to the ones found on routers and if it does, what exactly does it reset!?

    After this we might look in to software. I think there are settings to disable the Fn key all together, may be that is the case, does the Fn key work at all with the other keys?

    No luck. The fn key does work with other combinations, but the combination of fn and f5 still is not working.

    Does it work as you turn the system ON before Windows loads then stops working?

    I saw this somewhere else, it talks about a TV which is not your case but may be your Fn + F5 is over ridden too!

    I tried that and have had no luck. I also tried closing applications that may interfere but nothing is working.

    I guess last thing to try would be Safe Mode or a linux Distro on a bootable CD such as UBUNTU, may be even Hirens Boot CD with Mini XP to rule out windows, you also didn't say if you have this issue before Windows loads.

    If you have no Tray ICON as in the Quote, did you try Right Click on the Desktop to check the properties of your display adapter/ driver?

    You said Fn works, so it wouldn't have to do with it being "locked" by hardware or software.

    I don't believe the F5 is stuck or broken ... Monitor works, cables are good ... I don't know what else to try ... may be something specific to Acer One?

    It will not work before windows loads. I tried to switch monitors in ubuntu, but it looks like that feature is unavailable. I tried updating the BIOS from the acer website. Now the computer shuts down while starting up. Right now I have the previous version of the bios on a flashdrive, but having trouble downgrading it.

    Ouch ... how old is your Acer One? We had more than one Dead out of the Box but that was over a year ago but we get more Acers than any other brand in for repair. I've seen some run for ever.

    You can't downgrade beacuse the system shuts down or oes it shut down as it is loading Windows.

    Did you load the default after BIOS update and made some changes, certain values needs to be changed, they did have OS install mode and some other values that affected how the system started up.

    Check the Acer Launch Manager.

    I got it back and running, however the fn f5 combination still doesn't work. This is a pretty tricky problem. I'll keep searching for answers, and hopefully I will figure it out. I'll survive until then. Thanks
