Yoga 3 Pro won't turn on

Last night I was using the laptop and didn't notice the battery was almost dead. After it died I turned it back on and used it for a few more minutes, when it suddenly shut down with no warning. When I tried to turn it back on, the orange battery light flashed twice (with it plugged in). After a few more attempts, it now does nothing when I press the on button, no lights or anything. Same thing whether plugged in or not.

 

Also, half the Torx screws appear to be stripped all of a sudden, so I can't remove the battery either. Help?

Re: Yoga 3 Pro won't turn on

The situation seems "not great", but fixable.  I get machines that someone has already "fixed", so I see some messes.  There is no reset button.  You were doing what I would so, disconnect the main battery, but stripping the screw heads makes things difficult.  Usually, torx screws are hard to strip if you are careful and the driver fits, but it can happen.  I use a reverse-thread 2mm bit in a drill set to spin backwards.  (just as I would do if they were philips screws)   I drill slowly through the head and either the head starts to spin by itself, meaning it is no longer connected to the shaft, or, more likely, the whole screw spins out.  Obviously, the screws will need to be replaced.  You can use a normal philips 3mm or 3.5mm screw.  If some of the heads came off without the shafts, there should be enough to grab with a small pair of vice grips.

It turned out the screwdriver was the issue, not the screws. Picked up another one and it worked like a charm.

 

Is there anything else I should do besides removing the battery? I read something about removing the RAM too.

Removing the battery did nothing. **bleep**!

If you try a T-4 torx, it seems like it fits, but the driver is too small and you don't get much traction.  It is really T-5.  I would just unplug the battery.  Let it sit for a minute or two with battery disconnected and push the power button a couple of times before plugging the battery in.

Nope, unplugging the battery didn't work.

I don't remember if there is a way to disconnect the CMOS battery on the underside of the motherboard.
