Yoga 2 Pro black screen after graphics driver install

Clean install Win 10

Windows installs Basic graphics driver, which works

Install Intel graphics driver, and screen goes black, laptop still running

I have tried 2 different drivers from Lenovo and 1 direct from Intel

Same symptom with all

Any ideas?

Re: Yoga 2 Pro black screen after graphics driver install

What exact version of Windows 10?

What is the exact model (MTM) of your Yoga 2 pro?

What driver versions are you trying to install from Lenovo?  (I only see one availabe which is version 10.18.15.4240 dated 7/14/2015 for Windows 10 64-bit, and the generic Intel drivres are always hit or miss since they have not been certified by Lenovo.)

Have you updated the chipset drivers for your system?

Re: Yoga 2 Pro black screen after graphics driver install

Win 10 HP 64

MTM 59418309

 

Yes, tried that driver version

Installed All supplied lenovo drivers first, including chipset, and same problem

Tried the same with Win 8.1 and still black screen after graphics driver install

Display works in Linux Mint 18, but naturally have to adjust resolution lower

Thanks for the reply JD

 

Edit: Note this has the newest bios version

Tried again with win 8.1, original drivers found on original ssd, and same outcome.

Solution is to junk it, enough of this

Re: Yoga 2 Pro black screen after graphics driver install

Well, went after this problem from a hardware angle

I have "Heat Treated" many laptops with black screen and no post

Before this, all were older amd cpu and graphics with separate graphics chip on motherboard

From what I understand, the solder would crack on the bga

Sometimes lasted a week, sometimes a month, sometimes longer

Reasoned that the separate graphics package on this processor die may have a similar problem since it is also bga

Removed motherboard, heatsink assembly, and masked off the gpu die with foil

Used my trusty pencil torch and heated. How long, don't ask, I go by feel and experience

Also, the heatsink did not completely cover both gpu and cpu on the die

What the heck were they thinking? There is a cutout in the copper, and just

a thermal pad was used for the gpu part of the die

Cut a small copper shim to fill the cutout, thermal paste both sides, and reassemble

Well, it worked. Now, installs graphics driver just fine

Tested in win 8.1, and then clean install win 10

Seems good, how long will it last, is the question

 

This post is for repair techs, and not for all the casual readers on this excuse for a help forum

I wish Mark Lenovo was still here, there was a good crew back then, proud to say

I was one of them.

Turned out to be a hardware problem, posted my fix but the post vanished

Got it going though, heat treated gpu section of cpu/gpu die

That was My solution
