My wife and daughter both have/had Lenovo Yoga touch screen convertible laptops and about a month ago, within 24 hours of each other, they both went kaput. Hit the power button and the light comes on for a second and goes out and they never even make it to a BIOS or Lenovo logo screen. Not the exact same Yoga models either. Nothing else in the house had a problem and with laptops having an AC adapter, I wouldn’t think a power surge would do anything. No stormy weather or lightning at the time.
Was it Windows?
If you can’t even get to BIOS, then it’s catastrophic hardware failure.
Memory, CPU, chipset.
No: it sounds more like memory or the mobo if you cannot even got a screen.
Forget the power button. Some times it’s best to just pull the power cord and leave it off for a couple minutes. Most every electronic device will do a full reboot that way.
It was Lenovo. They all pieces of sh*t. I made the mistake if buying two different models over the course if a few years. Neither lasted more than a couple of months.
If the battery is removable, take it out and unplug the cord as well. That is generally necessary to get a hard reboot of notebook computers. If that doesn’t work, check with the manufacturer to find out if there are any key combinations that will force a hard reboot.
