EliteBook 840, laptop runs very well, battery backup is around 1 hour 30 minutes, when speaker volume is turned up high the sound is not clear, at low volume the sound is clear, keyboard / button works less, sometimes it works and sometimes it does not, when clicking Shutdown button sometimes the laptop shuts down and sometimes it restarts. Then I manually press the power button to turn it off, this might be a Windows or BIOS set-up problem, many have said. What you see in the picture is exactly what it is
