Sony Vaio All-In-One, Keyboard Not Responding

[Pablo44]

My Sony PC is running Windows 8.1 - Model is SVL2412M1EB

When starting up the PC a start screen appears which requires a keyboard input (like pressing the Esc key) to take me to the Windows log-in screen.

This suddenly stopped working and I am now stuck on that initial screen and cannot get any further. I have checked and replaced the batteries in the keyboard and the mouse but no change.

I have also tried plugging in a USB keyboard and that didn't respond either. Everything else seems to be working fine and Windows seems to continue loading but I cannot access anything as the screen is stuck on the initial image.

Any help would be greatly appreciated.

PS The keyboard antenna light flashes orange (which I think it did before too) but the mouse doesn't light up at all

Is the mouse working?
You should be able to log in with a mouse-click.
If a password is required, you can use the On-screen keyboard to enter it.
(There's a little icon at bottom left which will activate the onscreen keyboard).
If you can get to the desktop like this, you can then investigate further.
Sometimes when p[lugging in a different keyboard, the drivers won't load for the first time until you are logged in.

Also, some wireless keyboards need to be paired with the receiver after a battery change. How you do this will depend on the brand of keyboard, but it is usually a variation on - long-press button on receiver until you see a falshing light, then press button on underside of keyboard.

Thank you for your reply.
Unfortunately the mouse isn't working either so I cannot get to anything past the initial screen.
I believe that on this model both keyboard and mouse are connected via bluetooth but I'm not sure about this.
Shame they don't give you manuals anymore.

You haven't inadvertently turned off Bluetooth, have you? Is there a button somewhere that you might have touched. eg, by laptop has a button to disable wi-fi and another one for the touchpad.

[Pablo44]

Thanks for your reply but there is no bluetooth switch or button on this model, the bluetooth controller is internal and thus not accessible from the outside.

Do you have a system repair disc? I'm wondering if you have a problem with your HDD and need to do a system repair.

Thank you all !
The issue is now resolved thanks to the John Lewis Tech team at Bluewater.
Special thanks to Paul, who managed to find a Sony 'ASSIST' button on the side of the display which allowed him to restore the PC to a point previous to the problem arising.
It was probably due to a corrupt driver possibly the result of a Windows update.
Back to work now after getting rid of the initial start screen.
