Re: Z460 suddenly shutdown randomly

no errors, no dump files.

how about heating? is it normal?

when you see lenovo logo press f8 to load on safe mode and check if issue persists.

( maybe it's just graphic card drivers )

Re: Z460 suddenly shutdown randomly

yes, windows didn't knew who direct to shutdown? it just knew that the system had lost power kernel 41 which same before and after restore and updated. but it didn't knew what is going on inside hardware design or protection scheme to cause shutdown and then can not boot again even remove the batt and ac adaptor for a long time.

 

sometime in several time  open from the bag can not boot also?

 

the system in very normal temperature, some indicator are ie; top cover cool enough cause this unit put in 24 degree celcius room temp and air ventilating cool enough.

 

i already done via f8, to check memory check the others the result nothing error report or zero.

 

in my mind lenovo designer knew what are protector inside to drive the unit shutdown and can not boot again...........

 

hi lenovo designer are you here ?

Re: Z460 suddenly shutdown randomly

maybe hard disc issue.

i suggest you to call lenovo support line and ask for replacement.
