Title:
[HP Pavilion dm1z-3000 CTO Entertainment Notebook PC] Keyboard
randomly loses and inserts keystrokes (often!)
Status in linux package in Ubuntu:
Expired
Bug description:
With my hp dm1z-3000 laptop, while typing in several applications (ex.
libreoffice and firefox) sometimes it starts missing characters and
occasionally inserting extra characters - input will stop (while I
continue to type) and after a few missing keystrokes operation will
resume, oftenwith a few (to a dozen) extra characters are inserted.
The extra characters will be the same (for the occurrence), and one of
the characters I typed (I think it may be the first "missing"
character). For example, say I was typing "partridge", and this
problem occurs when I type the "t": I might get to the end of the word
with "part" displaying, then "partrrrrr" might appear.
I type at 80 words per minute. If I type at 20 words per minute, this
does not occur. This is not a hardware fault: I replaced the hard
drive before installing ubuntu, so I reinstalled the windows 7 drive
to see if the problem was present. All keyboard operations returned
to normal with the Windows disk. I again swapped out the disks, then
reinstalled Ubuntu from scatch, reformatting the disk. The fault
continues to occur.
I note that when this is occurring, I find the following in syslog:
