Y560 - PLAYED WITH BIOS FOR FINDING ATI GRAPHICS CARD AND NOW ITS BLACK SCREEN

HELLO TEAM

I have bought a second hand Lenovo y560, and I have done a clean win7 Ultimate OEM x64 Bit install. After this I couldn't see the ATI  graphics card in the device manager. (im not sure it was there before install). I have done all possible methods to find it using AMD software update tool, but it says no hardware found.. it was showing 2 Intel HD Graphics Cards

 

Later I tried fiddling with bios and changed some values in "Configuration Tab"related to switchable graphics  to "discrete", below that some parameter like VMM ( blame my memory not sure) . Later I rebooted after saving changes and the screen has gone black. I tried bios update recovery (Wincris USB bootable method) option mentioned in the forum, and it did not work..

 

(Earlier I had tried updating BIOS, it failed and I used Wincris recovery by making bootable USB and it was successful)

 

Can any tech friends out here could help me getting back to screen, Thanks a lot in advance

Hi jakes

Welcome to the forum!

Dont worry mate, it is not that serious, i mean it is not a hardware problem, just the graphics have switched to discrete mode.

To fix this, switch on your laptop, and as soon as the lights start coming up, repeatedly press the f2 key and you should probably hear a small thin sound(if you dont hear the sound, still continue the steps, it may take once or twice to work). You have entered bios here. Here press f9 once and then press enter. This has reseted the bios to default settings. Now press ESC twice and enter and the laptop should reeboot and hopefully it works.

You can also take a look at the bios simulator before doing this, so that you can get some practice.

Hope this helps
