Yoga 12 Wake up from Sleep problem

Hello,

 

I have problem with Lenovo Yoga 12 ultrabook. When I want to wake up computer from Sleep mode, computer beeps 4 times ( 4 beeps x 4 ). I read some solutions there but not work - I am running latest BIOS, latest Intel HD Graphic Driver, iSCT missing in BIOS so I cannot disable it, Realtek PCIE driver updated too.

Please help me, I don't know what more I can do.

 

Thank you

Good day and welcome to the community.

Sorry you're having difficulty.

This thread, although for an older model ThinkPad, describes the same beep sequence:

Unfortunately, it may mean a system board failure.

 

Regards.

Re: Yoga 12 Wake up from Sleep problem

Thank you for your respond, but if there is HW problem, I can't turn on computer anyway.

But I have this problem only when I wake up computer from sleep.

Turn on and restart are without any problem...

That link on problem what you send, there is problem to turn on computer.

 

Thank you,

Eremej
