I have a Lenovo Z710 laptop with a defective battery.
After 2 failed attempts to install Windows 10, I tried again, this time I uninstalled Avast antivirus and disconnected from the Internet when Windows 10 was downloaded. I also removed my laptop defective battery.

On the third attempt the installation succeeded, but Windows 10 froze after a few minutes, with the error message "Drive_Power_State_Failure. I put the battery back into the laptop, and now I have no problems with Windows 10.

I do not know if it was battery removal which helped, or whether it was uninstalling antivurusprogrammet and disconnecting internet.

So my tip is, removal of a defective battery might be the solution.
