Thks. But that is the last what I would like to do. I have just transferred all files,but need them to work with and can not wait until new mother board will be replaced. Is it the only way? May be there some "tricks" to wake up or here is major failure?

I am having the same exact issue.  I have the T420s.  This computer is practically brand new.  I can't turn this computer on to save my life.  Have you found an explanation for this? 

 

Thanks

Please check the USB ports by view from outside, whether the plastic "tongue" still exists there inside and there is no short with the contact pins.

 

Also pull the BIOS battery for a few minutes after detaching wall-power and main battery. - See Hardware Maintenance Manual
