Try going to Device Manager > Click the > next to Keyboards > Update Driver Software

Use the Auto option

 

If this fails right click on the device > Uninstall

 

Win 8.1 will re-load the drivers when you boot up.

nope, nothing, its weird because ive tried a bunch of other working keybords and non work on this laptop, but it was fine till an update about a week ago

[KenB]

it was fine till an update about a week ago

Try a system restore to a date that is just before the update.

I can't seem to find the system restore, only recovery, I might do that though, it needs a bit of w clean out lol

[KenB]

I can't seem to find the system restore,

Open the Search option > type in "Recovery" [ no quotes ] > click on "Recovery" > System Restore is here.

[jayden-lee]

nope, nothing at all, i tried the earliest and still didn't work, i really dont want to have to fully reset my laptop but i will as a last resort

[KenB]

ive tried a bunch of other working keybords

I assume these were USB keyboards ?

 

Do the USB ports work with other USB devices?

 

===================

 

There is an option to Refresh your PC.

This will not affect files and data.

It will, however, revert your pc to pre 8.1 and this will need to be re-installed.

It will remove recent updates.

It will restore everything to original settings.

 

This may be worth a try before a total reinstall.

Windows 8.1 switched to Intels xHCI USB controller interface, which is far different then that of other generations of controller interfaces. It could be that Acer has not released a driver yet that is able to communicate from your keyboard to the controller interface.

 

The simplest way to fix this would be to search for driver updates. To see if their is an update for your USB's hit the Windows Key and type "Device Manager". Open it and scroll down a ways till you find a section called "Universal Serial Bus controllers", click the arrow and a drop down list will appear of all the different devices on your system. Go down the list and right click them, then select "update driver software" there may or may not be an update for the device.

 

If none need updating , you can disable the new interface and use the older generation. To accomplish this go to the UEFI BIOS and under the advanced tab disable Intel XCHI Mode and that should fix your problem.

Hi Jayden, to get into the UEFI Bios system, from boot up tap the F2 key.

sorry didn't get round to that as i only just got back from doing some banking and found i can use my keyboard to change screen brightness and volume but thats it

Acer has a video to get into the UEFI, on its website.

All I can find is uefi and if I change it, it can't find the operating system till I put all the settings back
