Most of the keys on my Lenovo y560p work fine usually but sometimes some of them will register incorrect keypresses.

For example, the u key will register as "volume up", the n will be "ESC". But most of the others will be fine. USB keyboards work fine. Seems to happen intermittently.

Laptop: Lenovo y560p
Ubuntu: 10.04 LTS

You might have one of two issues:

Either a hardware issue and your laptop is having problems with the cable or circuit related to the keyboard or a misconfiguration of the keyboard layout when Ubuntu was installed or after it was installed.

Turns out it was a hardware issue, as I installed Windows 7 and the same keyboard issues appeared.

Was covered by Lenovo warranty. They exchanged it.

The problem actually is the keyboard ribbon that plugs into the motherboard. Same issue happened to me. The ribbon rubs on a sharp edge on a heat sink, eventually grounding out after some time.

Solution: I used a small strip of electrical tape to insulate the ribbon where the heat sink rubbed it and exposed the small conductive material inside. I haven't had an issue since.

The heat sink is a bad design flaw that Lenovo should fix!
