So last night I received a notification for bios update from my Lenovo yoga 510 14IKB and I started the update. I left the laptop for a while since it went for a restart but when I checked after a while then I saw the power led on but no display. I let it be for a while thinking it's updating but after few hours it was the same . I unplugged the power cord and held the power key until it shut off( the led light). I tried booting it again but this time only the keyboard backlight and power led turned on. I can hear the fan spinning but it shuts off after a while. I tried resetting the cmos by unplugging the battery and cmos connection. As well as using the Lenovo one key recovery button on the side. No effect, there is no display I tried connecting to external monitor but still no display. I have a lot of work to do for my thesis and I have no secondary computer available. I really to get it working. Can anyone suggest something. My warranty just got over 9 days ago so I am afraid any repairs will cost a bomb on my student budget.
Please any help is appreciated.
 
Try this...

1. Turn the laptop off (not sleep or hibernate but off).
2. Connect an external monitor to the laptop.
3. Turn on the external monitor.
4. Turn on the laptop.

NOTE: You may have to press an "external monitor" button. Could be the f4 button or a button with two monitors on it, for the external monitor to work.

If you can see fine on the external monitor, then your attached display, or the ribbon cable that connects it, are your problem.

If you can't see on the external monitor at all, or the problem occurs on the external monitor as well, then it is probably the graphics card/GPU that is the problem, which may require the motherboard be replaced.
