This I observed on HP notebooks.

Perhaps you try with another keyboard, just to eliminate the keyboard as
source of the problem

if it is Generic 105 - what is the language and setup

setxkbmap -model pc105 -layout us

on Microsoft Multimedia keyboard (don't blame me for the M$ thing :) - it
turned out M$ multimedia keyboard was the best I could find with wire/USB a
normal key layout and multimedia keys. I don't understand why vendors start
either putting the pipe key somewhere at random on the keyboard or just
omit it)
