Lenovo Y50-70 doesn't boot

Dear Lenovo community, please try to help to solve the following problem:

  • I have Windows 8.1 OS
  • After recent update and restart my computer I got this problem - it's not booting up
  • After pushing power button it starts as normal (fans, lights) but I have black screen 📺 
  • It stays like working with proper fans noice but display is black
  • BIOS mode doesn't boot either with small button, this I don't understand why bios is not working neither...
  • I try to power off and start again - the same situation
  • Indicator of hard disk on the front panel is blinking with constant tempo
  •  IMG_0058.JPG
  • I have this problem since one week and sometimes laptop starts booting as normal after like 5-10 mins waiting with the black screen; and then works normal; when I send him to sleep it's also no problem to wake him up but when I reboot or shut down problem comes back
  • sometimes I can keep him running after start like half an hour but it's not booting, then I shut him down and start again, and maybe again. This can start working like randomly...
  • today I tried to install windows again but after restart it's not booting again.

 

What this could be? What can I do? If this is the problem of hard disk, then at least bios would start normally... or it's a problem of motherboard?

 

Thank you in advance for your support!

Remove that Ethernet cable and try to boot to bios -
I had issue like that but when it was running and left few mins it was not waking up until i force shutdown it , however this looks like same problem that E540 had.
try with one ram if you can open the back . my problem was driver conflict .

Hello Zhiar,

 

thanks for hints.

 

Actually I have no Ethernet connection, always use wifi for internet.

 

I also tried with one ram - doesn't work neither:

How can I take out the data from hard disk? Some special adapter, right? Is it 2.5"?

 

I really don't know what to do...

sorry for late reply , i was off all day,
you ether buy sata to usb cable , comes cheap (9 bucks)
or you can take harddrive out and put it in another laptop -it will boot just fine -just without drivers so you will be able to access your data I think you need to tun off legacy boot on the laptop .

Re: Lenovo Y50-70 doesn't boot

I have the same problem with Windows 10 and BIOS at V1.14 Rev 3.7.

 

With only one 8GB RAM I cannot try removing one. Was there any solution from the guy who started the Topic?

BIOS intalation maybe corrupted, had exactly the same problem, installed the bios update and it was resolved, but it was very difficult because to install it I had to rely on the pc randomly booting. But then after trying sometimes it worked! Everything is fine now

Re: Lenovo Y50-70 doesn't boot

I have the same problem. But I also noticed a clicking sound from my internal speakers. It's more of a loud popping sound if I connect external speakers. The problem started some weeks ago, but normally it only took a few seconds and clicks/pops and the BIOS screen came up. When the system finally started everything was working normally.

 

I hope I can somehow get it to start again so I can update the BIOS if that really fixes the problem...

Re: Lenovo Y50-70 doesn't boot

Hey buddy I have the same problem at the moment.

It seems it is version 3.03 of the BIOS.

Put the laptop in the freezer for 10-15 min and take it out and it will turn on.

(it many take up to a few minutes, but it does)

revert the bios back to version 3.  I am having an issue where it wont revert.

(remember to turn on backward flashing in the BIOS)
