Hi folks,
I'm desperate, i asked several forums run in my home country, but no one was able to help. Lenovo Tech Support after warranty is suggesting: please reinstall OS one more time.
Patient:
Lenovo Yoga 900-13 ISK, Win 10 Home, Machine type - Model 80MK00G3PB, link to model specs: https://psref.lenovo.com/syspool/Sy...enovo_YOGA_900_13/Lenovo_YOGA_900_13_Spec.PDF
Background:
My sister has, described above, laptop. A few months ago she start to complaint that "computer is turning off itself" in the middle of the work.
My investigation:
I took it from her and used normally for a few days. It was working. I updated drivers and gave it back. She reportwed that problem still existed. I took one more time. This time I run a few benchmarks and several other stuffs to heat it up. I measured temperature (it was ok). Finaly i replaced cooling paste under CPU and reinstall OS. Of course sister reported that nothing changed which was really annoying because i was unable to saw the issue.
After a while accidentaly I found it. When I am using combination of buttons Win+Tab it is crushing. It is not turning off, but screen become black (only backlight is working) computer doesn't react for nything except power button. I thought something with screen/display and resolution (becouse Alt+Tab ws working). I checked Display driver log, no errors. I used older drivers, another one from different source (not from Lenovo but Intel), i reinstalled OS to check on "fresh" OS, check with register. Nothing. I checked the same issue working on ac adapter and battery. I unpluge the batter and checked on acad only and the same.
Now even after reinstall of OS it is crushing during OS boot. Only possibility to use PC is: run Repair mode in Win 10, change the resolution of the screen to lower then base 3200 x 1800 . Then it is working. In lower resolution even Not working previously Win Tab is working.
So Why am I writing here? Because i gave back laptop and advice to use lower resolution. After several days shje reported that poroblem came back even in lower res.
Do You have any idea what might be wrong? Hardware problem i'm not sure if is a root cause, it is working after changing the resolution. Looks like some problem with screen and scalling maybe?
