Developer’s Description

By Aleksey Tihomirov
Control LCD screen brightness on Intel GMA video adapters.
Absolutely free, very small and useful program for change and restore (after reboot) LCD screen "hardware" brightness on Intel GMA family video adapters (all Atom laptops and much more). Program permanently "live" in taskbar of the Windows (right-bottom place near watch) and show small icon with current brightness in percent. Brightness levels percentage is 0, 8, 13, 19, 26, 36, 50, 70, 100 ("progressive" row), but You may change it by editing INI file. Tested on Samsung N145 and Windows XP SP3 only (sorry, but other hardware not available for me). Works with Asus eeePC (based on eeectl source code). Use Alt+Win+Up and Alt+Win+Down (default) for change screen brightness.Based on eeectl source code.
