I read your comment and in my head I said "This." but I hate when comments start with a solitary "This." so I have managed to avoid that through meta-commentary. About a week ago my fairly new Clevo OEM/ODM (the actual badge on it doesn't really matter) laptop wouldn't come back to life from sleep – screen was black. The AC cable/power light and the battery light, both those lights were on meaning the machine wasn't dead dead. After waggling the mouse a bit, running my finger over the trackpad, pressing the power button a bunch of times, and striking random keys on the keyboard … I still had a dead laptop. So I did what any one of us would normally do in this situation. I held down the power button for a good ten seconds expecting the machine to power off, and from there I expected to boot the machine back up and have it complain to me that it had been unsummarily shut-off and could I please not do that. No dice. Tried this reliable technique a few times and still no dice. I could not believe that my newish laptop (about three months old) was dead as a door-nail. So unresponsive that not even holding down the power button until it switched itself off would work. Absolutely black-pilled and pretty determined to ask the manufacturer for a refund I rang up tech support fully expecting to be on hold for about half-an-hour but thankfully got through fairly quickly. I explained the situation to the techie and was surprised when they said, “Disconnect power, take out the battery, hold the power button for 30 seconds.” I've been around computers a long time and I'd never hear this one. Extremely dubious I did what I was told and, as you say, “Voila. Fixed.” Machine sprung back to life. (After reinserting battery, reconnecting power, pressing power button – obviously.) What. Sorcery. Is. This?
