Yoga 900: will not wake from sleep

Yoga 900 will not wake from sleep. The power button on the laptop is blinking, indicating the laptop is in sleep mode. Pressing the power key has no effect. Pressing power key for a few seconds (hoping for a hard reboot) also has no effect. Must remove battery to reboot the computer. This is an intermittent problem. The problem occurs randomly. I have not been able to establish any pattern related to how sleep was initiated (e.g. was sleep initiated by: closing the lid, clicking on sleep in the Windows GUI, pressing the power button). The problem has occured 5 times but it is a major hassell when it occurs.

Hi pricehale,

Welcome to the Community Forums.

Based on this forum thread Amy_Lenovo suggested to update the BIOS of the laptop. Please try to update the BIOS and also try other suggested solution by other users on that thread.

Let us know how it goes.

Regards,

Re: Yoga 900: will not wake from sleep

Hi.  i have the same problem where it will not wake from sleep or when shut down and resetting the battery and plugging back into main power for a few seconds is the onlly way to start the pc even with 100% charge

 

My first thought as you suggested was to re-flash the bios but the bios utillity will not reflash as it says the bios is the same, being version e1cn47ww.  what is the workaround for this please
