X250 ThinkPad "i" Lights Up

I see the dot of the "i" in the ThinkPad logo is back-lit (the dot glows red).  It appears to show the computer is in use, sleeping, etc.  Not sure the value of that given that I seemed to survive without it in all my previous ThinkPads.  Does anyone have any insight as to why they added the red-dot "i"?  For those that may not have noticed, it is in the ThinkPad brand logo on the backside of the LCD (backside of the computer screen - facing away from you as you use the system).


Is there more value to this than meets the eye?  Just curious.


Thank you.

Re: X250 ThinkPad "i" Lights Up

Hi Technobob,


The light in the ThinkPad logo "i" shows the same status information as the light in the Power button (which you cannot see when the lid is closed):


• Blinks for three times: The computer is initially connected to power.

• On: The computer is on (in normal mode).
• Blinks fast: The computer is entering sleep or hibernation mode.
• Blinks slowly: The computer is in sleep mode.
• Off: The computer is off or in hibernation mode.
