ThinkLight
The ThinkLight was a keyboard light present on many older ThinkPad families of notebook computers.
The series was originally designed by IBM, and then developed and produced by Lenovo since 2005. The ThinkLight has been replaced by a backlight keyboard on later generations of ThinkPads, and Lenovo has discontinued the ThinkLight in 2013.
The ThinkLight's origin can be traced back to the user-centric design philosophy of the original IBM ThinkPad team. Introduced on the ThinkPad i Series 1400 in 1998, it was a simple yet elegant solution to a common user problem: needing to work in low-light conditions without the glare of a desk lamp.
IBM Designer David Hill came up with the idea while on a flight from Japan back to Raleigh and not wishing to turn on the overhead light to illuminate his keyboard. Hill handed off the idea to IBM Yamato to create a prototype which was tested and approved by Adalio Sanchez, the general manager of ThinkPad.
This single LED on the display bezel became a hallmark of the brand, much like the iconic TrackPoint, and was a signature feature on many ThinkPad families.
A white or amber LED (depending on model) is located on the top edge of the display, illuminating the keyboard to allow use in low-light conditions. It is activated with the key combination Fn-PgUp (the bottom left and top right keys of the keyboard). Later ThinkPads use the combination Fn-Space instead. Lenovo later started to include backlit keyboards, and some models included both the ThinkLight and a backlit keyboard. For those models, the Fn-Space shortcut is also used in conjunction to control a backlit keyboard (if the laptop has it). The on-screen display of ThinkPad computers will display a light on and a light off indicator. The ThinkLight can be activated when the monitor is on or off but not while the computer is off.
Some ThinkPads, like the Z and R series (though not all - some R61 and R32 models still have the white light) feature an amber LED due to the lower cost, while other models, like the T series, use a white LED (which is generally preferred).
The G series and SL series omit the ThinkLight.
