Nearly went into panic mode this morning. This new laptop of mine is set to go into sleep mode after 30 minutes if not used and on battery power, well I left it on this morning and went off to do other things in the house, was gone probably a couple of hours if not more.
When I came back course I had the black screen but thought nothing of it and tapped the space bar, which usually brings it out of sleep back to wherever I was when I left. Nothing happened and looking at the power button saw that it was not lit, I pressed it to turn the machine back on but nothing happened.
The mouse was lit and the keyboard would light up when I pressed the button to activate the feature, apart from that, nothing, looked at the power cable and saw it wasn't plugged in so wondered if the battery had run out.
Plugged the machine back into the mains but still nothing, I did manage to turn it off by holding in the power button but I left it connected to the mains. There is a small light beside the plug and that was showing red so I just left it.
Powered up the Asus Notebook and started to use that, after a while the light turned to white but I still left it. After a good time had lapsed I pressed the power button which lit up and the machine booted up as if nothing had happened.
Obviously, the battery had drained so I had to wait till there was sufficient juice back in it before anything could work again, at least I'll remember if it happens again.
