How to Adjust the Brightness on an IBM ThinkPad Display
IBM announced the sale its PC manufacturing division to the Chinese company Lenovo in December of 2004. Since then, Lenovo manufactures and supports all Thinkpad laptops. One of the reasons the Thinkpad is so popular with consumers is that the keyboard functionality is very consistent across all Thinkpad models, with only minor variations for specialized functionality in some of the newer computers. You can control the brightness of a Thinkpad display through a keystroke combination or using the Thinkpad Access IBM utility that is pre-installed on the laptop. Change the default display brightness using the taskbar Battery Maximizer utility.
Keystroke Control for Display Brightness
Locate the Fn key (usually lower-left side of keyboard) and the Home and End keys (usually upper-right side of keyboard).
Press the "Fn" key and the "Home" key at the same time to increase the display brightness. A green brightness indicator gauge will appear on the screen to indicate the brightness level. Repeat the keystroke combination until desired brightness is achieved.
Press the "Fn" key and the "End" key at the same time to decrease the display brightness level. Repeat the keystroke combination until desired brightness is achieved.
ThinkVantage Control for Display Brightness
Click the "Start Menu," then click "All Programs" and locate the "Access IBM" program group.
Click "Thinkpad Configuration" and click "LCD" to open the brightness control dialog. Select the brightness from the drop-down menu and click "OK."
Click the red "Exit" button in the upper-right corner of the Configuration utility to close it.
Taskbar Utility for Default Brightness Control
Double-click the battery indicator on the taskbar to open the Battery Maximizer utility.
Select a power scheme that has the default brightness level you desire. If you do not find a scheme that matches your requirements for power settings, you can select one that is close to what you want and click "Create New Power Scheme." The utility prompts for CPU speed, monitor shutdown, laptop standby, hard drive shutdown, LCD brightness and a name for the new scheme.
Click "OK" to save your default setting and return to the Battery Maximizer utility.
Close the Battery Maximizer utility. The new power scheme will take effect right away.
