Hi,

I've got 2 Acer Aspire 5 A517-51-laptops of which the keyboard is not working. The only key that is working on both of the laptops is the power-button.

I've already tried resetting the battery, disconnected the keyboard-cable but the keyboard won't work. It has nothing to do with drivers in Windows because the keyboard isn't working in the bios (or a knoppix-boot-disc) either.

Any ideas to try?

    Most likely hardware. My best guess is the KB cable wedge assembly. Maybe warped? The white push wedgies on the sides often break off or otherwise don't apply enough pressure to make good contact with the ends of the ribbon. I've had to tape the cable end or use a mylar film spacer inside the connector on some boards to make good contact. The white line on the ribbon must be parallel to and just kissing the edge of the connector
