FAQ & Answers

  • Hi,
    Go to Acer support site, download and install Chipset driver version 10.1.1.13

    I've installed the Chipset driver twice already - I've even right-clicked on the device in device manager and browsed my computer for the driver and told it to look in all the subfolders of all the drivers I've downloaded already from that page and nothing!
  • Hi,
    You could try a battery reset, switch off the laptop, disconnect from mains, follow the instructions in the video, leave the laptop to rest for a while before starting again. Pinhole is next to HDD bay.

    Ooh! I've never noticed that before - the pin hole for the battery reset will come in handy for other issues so thanks for that!

    Unfortunately that hasnt resolved this issue as I just followed the instructions, re-installed the Chipset Drivers again but the Unknown Device is still showing up in Device Manager.  I've got 10 of these laptops that I need to get ready but I cant give them out with a missing driver.

    Thanks for you help with this.
  • Hi,
    OK, you could  try running system file checker command at least 3 times, the instructions are in this link:https://support.microsoft.com/en-gb/help/929833/use-the-system-file-checker-tool-to-repair-missing-or-corrupted-system

    Thanks for the reply, I'll give that a go but I've got 10 laptops all with the same missing driver so I wont be impressed if I have to do this on all of them as they're literally a couple of days old.
  • Yes, I agree that it's a pain it's missing in all laptops, give Acer support centre a call, they might be able to come up with a solution.

    That didnt work unfortunately.  However, I am getting closer to finding a solution but still need a bit of help!

    I just went through the 10 laptops and one was still as it was out of the box with Windows 10 S on, I used a digital key to upgrade it to Windows 10 Pro so I could run the DoubleDriver program on it.  I backed up all of the drivers and then copied the folder with the drivers in to one of the other laptops and got it to search through the whole lot and voila!  It found a driver it liked and installed it!

    The fact it was called ACPI 1025 (10251229) in Device Manager may be a bit of a 'red herring', what it actually is, is the 'Acer Airplane Mode Controller' - so I now need to find the driver for this so I can get it installed on the other laptops.
