I just upgraded my y40-70 laptop to windows 10 and my laptop is giving the error Internal Power Error and restarting.
it seeems that y40-70 is not compatible with Windows 10
I have restored my computer to previous build and it is back safe to windows 8.1
I don't recomend uprading to windows 10 for this model. unless Lenovo have solution to this problem.
Solved! Go to Solution.

I have a fix for this. The problem is the AMD Driver.
On another machine! Download these Drivers: http://www2.ati.com/drivers/amd-catalyst-15.7-win10-64bit.exe
That did it for me.

Based on our compatibility list from our support site here -> https://support.lenovo.com/us/en/documents/ht103535 it seems to me that Y40-70 and Y40-80 should be supported.
Thanks for sharing what you have found so far.
I am interested if the video drivers that you are noting here. Which model system do you have, and after you installed these drivers can you confirm it works without the error? Can you also confirm that you had the same errror as reported by others on this thread? I just want to make sure we are defining a common symptom.

I have a Lenovo Y40-70 Model: 20347 . It has the AMD Radeon R9 M275X discrete graphics card.
The working driver version on that graphics adapter is v. 15.200.1046.0.
I did have the same "Internal_Power_Error" Blue Screen as defined here. I first received it during the upgrade process directly after the screen "New apps for the New Windows". I then received it each time l logged into the machine, whether it is using my Microsoft Profile or a local profile.
I hope that this helpful.
