Lenovo Y50 won't start

Hi all! 


I have the exact same issue as the person in this thread (I also paste it here below). Are anyone familiar with this and have an solution for it?


I've tried the suggestion from the thread of removing the bios battery, battery, starting with only power cable and no battery, etc.


"Screen won't turn on, but everything else seems fine.

Some background info: I have a Lenovo Y50, I believe it's the y50-70 variant, but I'm not 100% sure. It's a 15.6inch with an i7, 16gb ram, sata drive, and an Nvidia 860m with 4gb of graphics. It was purchased in September of 2014, so it's a fairly early model of the y50. it's a bit beat up, but hasn't had any major functional issues to this point.

Now to the actual problem: When I boot the laptop, the keyboard backlight and status lights on the front all come on like normal, but the screen stays black (not just a black image being displayed, the screen is off). The problem has occured in the past, but was intermittent and could be fixed by letting it sit unplugged with the lid closed (I have no way of knowing if this actually helped, but it usually booted after that) for a few minutes before trying to boot again. The problem now seems quite permanent. I removed the backing last night and took a closer look, and the connections all appear to be fine. I'm not sure if it's relevant or not, but the laptop was left unplugged and powered off for about 72 hours before it refused to boot. The status light indicates that it still has battery, and I've tried it both with and without having the charger plugged it. I've also tried it with an external monitor without success.

My initial inclination is that there is a problem with the graphics card, or some other internals rather than the screen itself, but I really have no way of knowing, as hardware isn't my area of expertise. I'm a CS student, so if anyone could post answers ASAP, it would be VERY much appreciated."

Re: Lenovo Y50 won't start


Welcome to Community Forums @Zebsag!


Please check page 25 of your device's hardware maintenance manual to see details about screen blank state.


It states in there that:


"If the time set on the “Turn off monitor” timer in the operating system expires, the LCD backlight turns off. You can also turn off the LCD backlight by pressing Fn + F2. To end screen blank state and resume normal operation, press any key."


For that one, you can press FN + F2 again, or else press FN + F3 to opens the interface for selecting display options to change.


You can also try pressing the Novo button (small button that's next to Power button) from an OFF state to check if the device itself will respond. Make sure that there are no cables or adapters plugged into the laptop when doing this.


Another step to try is to turn on the laptop again and check if you'll see anything on the screen by using a pen light to check if it's an issue with the LCD or with the LCD backlight itself.


It would be recommended to have the device be brought to your region's service center should the steps above will not get the job done as this may seem to be a possible hardware failure.


Hope this answers everything. Regards.
