Title:
hp x360 laptop keyboard freezes for 1 sec. every few minutes
Status in linux package in Ubuntu:
Incomplete
Bug description:
A couple weeks ago Installed ubuntu 14.04 on an hp spectre x360. It
works great except for a strange keyboard problem. Every 2 or 3
minutes the keyboard freezes for about 1 second - it misses keystrokes
completely. Anything typed during that 1 second period is missed.
For that same period, the LED in the F5 key turns off. The F5 key is
normally illuminated. If you hit it, that turns the LED off and turns
on the keyboard backlight. Hit it again, and the backlight goes off
and F5 lights up again. Apparently while that light is out, the
keyboard is disabled.
I wrote a program that printed a variable character pattern to a
terminal every 4 times/sec and just watched it. I wanted to know if
the whole computer (or just whole desktop?) was freezing, or just the
keyboard. When the keyboard light turned off, the program kept
running, so I think it's just the keyboard.
The timing of the light blinking off is variable. If I am not typing, the
light seems to blink at a 2min 30 sec.to 3min 30 sec period. It seems more
often than that when I am actually typing, perhaps 2 minutes. I'm guessing
this is a keyboard driver problem? Anyone else seen this?
