I've owned my Y570 for almost 2 years now and it worked great the entire time! Recently, however, the laptop gets no power whatsoever. I was just playing skyrim on it yesterday and then i go to boot it up today and nothing, battery is dead, ac adapter does nothing. No lights on the front and doesn't power up. I checked my adapter and it's still at the proper voltage. I am a PC tech and have looked over the obvious things; I've removed ram and HDD, unplugged AC adapter and battery, held down power for 30 seconds multiple times etc. Still no power!
I've read other threads saying this is a known motherboard issue but I need to know from a Lenovo tech. Is this a common issue? Are there any easy fixes or do I need to spend 200$ to fix it? It's out of warranty and i've opened it several times to repair the hinges or to re-paste the cpu/gpu. It's taken a beating from my family misusing it but it was working JUST FINE up til today!!!

No power at all, no front lights, wont boot. I tested the circuits and the unit IS getting SOME power so im thinking there's some circuitry that failed or something... I've heard something about some power management issues with this particular motherboard but i have no idea where the issue is as i don't have the schematics and dont know what voltages to expect at each particular circuit etc. So yea complete brick atm.

I recently had the same problem. Luckily I had warranty so I RMA'd it. It was indeed a motherboard issue. Unfortunately the gpu on the new motherboard was defective, so I have to send it in again .

Try google for "copal" or "Insyde H2O". I am not surprise that you can't find any diagram. It has been a practice for a long time by manufacturers not to include any schematic diagram with their product.
