Y50-70 - shuts down after windows boot

2015-10-31, 22:38 PM

I am having problems with my new Y50-70. When i boot windows (7, 64bit), it loads, i hear the windows sound, antivirus starts and then suddenly the notebook shuts down. Its quick shutdown, like when you unplug power from regular PC, simply nothing. However, its only doing from time to time, completely random. After second start it works without problem. Only once i have faced this problem during normal computer usage (few hours works and then shuts down). It happens mostly when the power cable is plugged in, but i have also faced this when on battery.


I dont know if it might help, but I think its shutting down when the wifi is loading (the circle in the wifi icon). I am also facing disconnections from wifi network, but i thought that it is router problem (its old), but i am not sure.


Also, I had a problem that i saw several black horizontal lines on display, pixels were crazy (black wallpaper had some red, some blue and some green pixels, but they were still changing like christmas lights or what) and it was lagging very bad (even mouse was lagging). After restart it was ok. I have reinstalled graphics drivers and never faced this again, but it can be only coincidence.


Can the problem be windows related? Or there is something bad (driver/connection inside...)?
