As I was using my laptop, a Y50-70 Touch, it turned itself off and now I've been unable to turn it back on at all.
When I hit the Power Button it lights up for a second or so, as do the white LED indicator lights on the front of the laptop, but nothing else happens, the keyboard backlights doesn't turn on and there are no other sounds from the laptop, no fans, nothing. It does this with the power cord plugged and the battery in and every other configuration possible, nothing.
I'v removed the battery and tried to discharge any additional charge left by holding the power button down for extended periods of time, I've also hit it at least 30 times or more. It doesn't do anything when the battery is put back in. I've tried this multiple times.
I've checked every connector and they all seem perfectly fine.
Im out of warranty so I can't send it in to be fixed. This laptop has been a disaster, the screen constantly flickers and the hinges are both cracked. I'll never buy another Lenovo.

Hi siege101 ,
Welcome to the Community Forums.
Would the Power LED manage to stay lit ?
Would it still display anything if connected to an external monitor?
You can initially start with the power checkout to isolate adapter issue , testing on adapter and port hoping that since it had initial issue on flickering display either display issue or graphic issue.
Then again you mentioned that there is no fan activity and that even the backlit which is independent on p.o.s.t. suggest probable motherboard / powerboard and dc in port failure.
When did the warranty expired?
Did you manage to call in before about the display problem?
Do not leave out option to give a call to technical support as they may still be able to provide options for you as it is worth a try.
Update us how things are.

It's definitely not a problem with the battery or AC Adapter or power cord. I've tried the power checkout procedure.
The display flickering issue is because of loose cables, I've had to fix that before by myself. It's a common issue from what I can tell.
My warranty ran out at the end of 2015, I never called about the display issue because I fixed it myself.
I think the motherboard is broken. I tried to turn it on with another hard drive installed and got the same results.
Now I have to decide if I want to fix this piece of garbage or get a new laptop. A refurbished mobo seems to be around $250 with the CPU and GPU included.

Hi siege101 ,
POST (power self test) would still work without any harddrive , so best have it checked further for board isolation else to check on dc in port and power board .
But if you have already done so, review you option for such replacement and likewise a new purchase .
Other parts of the laptop is stil ok as some other people may also be waiting for those too like the LCD , chassis cover , ram etc for a good price as spare parts are more expensive that bundled to the pc.
As I would not give up easily on my gadgets, I still suggest to give tech support a call to get their views .
Hoping you for the best .

The hard drive is good, I've attached it another computer to check and it functions perfectly fine.
Unfortunately I think it really is the motherboard.
It's not the power board, since when you press the Power button the LED on the button lights up and so does the front power LED indicator.
And when connected to the AC adapter the front LED indicated that the battery was charging.
The hardware of the laptop is somehow not getting the command from the motherboard to start up. So like I said, it either needs to be replaced or I need a new laptop.
Im hesitant to fix this because I think the motherboard failure was from the excessive flexing of the plastic chassis of the laptop. This thing bends so easily, I've never seen a laptop with as much flex. Somehow that broke a connection on the motherboard.
