When starting in the morning pressing the front button has no effect.
I switch off at the back, wait for the LED in the start button to light momentarily, then switch back on. Then when I press the front button the computer starts and runs all day (until it is shut down at about 23:00), without any problems.
Any and all advice appreciated.
I shut the computer down manually at about 23:00 (I don't have to get up early so late nights are the order of the day here!)
I've tried shutting down and then restarting this morning and it restarted without any problems. That was just for five minutes, so later today I'll shut down for an hour or so and see what happens then.
