New laptop - weird key repeat issue

This new Lenovo E560 of mine is displaying one or two peccadilloes.

First and most irritating, keys start auto-repeating after a brief,
configurable delay - but if I hold the key down past that point for
half a second, they keep repeating when I let go of the key! They will
repeat indefinitely if allowed to do so, and if I move the focus to a
different window they will merrily go on repeating there too. The only
thing that stops a key repeating once it starts is to press another key
(shift, alt, ctl etc do not stop an autorepeating key).

This issue does not happen in a "real" console, but it does happen in
terminal windows.

Pretty much every key does this - letter keys, number keys, arrow keys,
backspace and so on, so it's not a sticky key. BUT: An external
keyboard (USB) does not have the problem.

With nothing attached, lsusb reports this:

Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 004: ID 04f2:b541 Chicony Electronics Co., Ltd 
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

I'm guessing the Chicony device is the keyboard.

All updates for 15.10 have been applied.

Similar issues have been reported in the past - waaaay in the past, and
not only with Lenovo - but it seems that this issue is still alive and
well and living in my laptop. Googling has brought no relief; does
anyone have any pointers?

Regards, K.
