ThinkPad Edge 431 Powered USB charging at only one port when thinkpad is in hibernate

I have a ThinkPad 431 with Windows 7 the BIOS  turned on for always on.

I switched on the USB option always on in lenovo utility.

 

Thinkpad has 3 USB ports, two on the left and one on the right.

The one on the right works when the thinkpad is in hibernation. The left ones don't. When thinkpad is on, all ports charge.

 

Is this by design or is there a problem with my Thinkpad unit. I really realy need two ports for charging.

I should mention that I don't have any yellow USB port. Neither the left or the right ones have yellow.

According to the User's Guide, pages 5 & 6, the USB port on the right side is "always on".  The two on the left are not.
