So I have a Yoga 260 that was fine for the 1.5 years that I owned it. Two days ago, I was at a coffee shop and locked it (in Windows) to go grab something. When I came back, the laptop was off and wouldn't turn on for anything (no light when plugged in either). At the time it was plugged into a wall outlet.
Things I've tried:
* Holding the power button for 30 secs with power cord plugged in and unplugged
* Removing the battery from the motherboard
* Unplugging the CMOS from the motherboard
* Holding the reset button for 30 secs with the power off, and 30 secs with the power on
* Using compressed air to blast dust off the motherboard (not much dust)
The Yoga 260 was running Windows 7 64-bit. Not sure what it could be, the power button looks and seem to press fine, so maybe it's the motherboard? Maybe there was a power surge?
Also, kind of an aside - the Lenovo support site is pretty terrible. I'm still not sure if this laptop is under warranty (I'm guessing not) and also not sure if I'm supposed to create a ticket for this MTSA support site or not.
Anyway, appreciate any ideas.

Motherboard sounds sick. I assume battery and CMOS battery were both unplugged at the SAME time for about 5 seconds. I also push the power button a couple of times with the batteries unplugged to drain capacitors. You can check warranty status here:
