Re: Lenovo z50 not turning on

Hi Mudau_A ,


Welcome to the Community Forums.


Would you have the machine number to be specific on the model ?


How was it if you connect to another external monitor and keyboard.

Any indication of power like led on , caps locks responding.


Turn off and remove the battery (if possible) unplugged from the ac cord.

Press and hold down the power button for 12 seconds to drain flea power then retry to power on using the Novo button instead. 


Review the steps described in this article Advance options if you get a chance fo a display to rollback driver or system restore the machine back to a previous date. 


Update us how it goes.

Re: Lenovo z50 not turning on

I have the same issue on my z50 laptop. I even returned it to Lenovo for a battery replacement.  It worked for 2 weeks and it’s dead again. I get the light on the front panel saying it’s powering on but no start up. I tried the battery removal and holding the power button for the 12 seconds but no success.
