Question

My ThinkPad S540 attached to ThinkPad OneLink Dock. Is it possible to boot directly from the OneLink Dock without having the laptop lid open?

 

The current issue is that when pushing Power On button on the OneLink Dock with S540 lid closed, nothing happens unless I open the lid then it boots right away.

Answer

BIOS version 1.55 should fix it.

 

To get the BIOS, you can access Lenvoo support site or click here: BIOS Update Bootable CD for Windows 8.1 (64-bit), 8 (64-bit), 7 (32-bit, 64-bit) - ThinkPad S540
