Hi,
my Lenovo Z50-70 NM-273 with Intel i5 and Nvidia N15 discrete graphics work only on battery. And even on battery it is not predictable how long it will last before crashing. Sometimes work for whole hour, sometimes 5 minutes, regardless of what I'm doing.
Same is happening no matter what windows is installed. Curretntly it is on Win 7 64bit, all drivers are installed without any problem - chipset, both graphics etc. Laptop does not overheating, it's clean and with new thermal paste. Furmark works just fine and temperature does not exceed 65 degrees.
Everything seems OK and, for no reason, laptop crash and stays off. Without restarting. Every time. No BSOD, no any error message.
Other problem is that when power adapter is plugged, it crashes instanly.
I can power it again with power adapter, but it crashes in shorter intelval every time. For example, it works on power for 5 minutes an crashes, than next time works for 3 minutes etc. At last, it can not even start.
When laptop is off, baterry charging works fine.
Does anyone have experince with that specific problem?
I have schematics but no boardview.
