, 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.
A few ThinkPads (17" W700 and W701) have featured the ThinkLight with dual white LEDs.

series laptops have also contained a pair of red LEDs which are controlled in a very similar way to the IBM ThinkLight and also serve to illuminate the keyboard.
Some computer manufacturers have opted for backlit keyboards instead of illuminating the keyboard from above; but some ThinkPads included both the ThinkLight and a backlit keyboard (for example, T530, T430 and X230 models).
