I did the same thing and uninstalled Intel's driver in safe mode, booted back into Windows and installed Intel's driver again. I then reinstalled Intel's driver, and the laptop worked fine for about a week before the powering down at the login screen started again.
I uninstalled it and was able to boot back into Windows normally using Microsoft's basic driver. Now at the login screen, the screen would glitch showing green horizontal lines over a distorted login screen, then power down.Įventually I seem to have traced the problem to the Intel HD 4000 driver. I tried safe mode, which worked fine, so I enabled memory dumps and verifier. Naturally I of course tried to power it back on, however as soon as the login screen appeared the same thing would happen. There was no warning or bluescreen, as if the battery was pulled. This is an issue that started a few months back on my Lenovo Z500 Touch laptop and it's been bothering me greatly.Ī few months back my laptop randomly powered down while I was using it.
