Hello,
I am recently encountering Black Screen issues when my IdeaPad Z400 Laptop is shut down/sleeped for more than an hour. When I open I see only Black screen, Lenovo Logo doesn't show, no Back lights, Power LED is on, USB working , DVD is responding, Hard disk seems to be spinning.
I can only power it on after N attempts of pressing the power button on/off. There are also times that the Lenovo Logo is showing but after 2 secs the power goes off.
No beeping sound. I did a chkdsk and memtest and everything seems fine.
