It isn't a bug it's a feature!! If your CX is the same as my 755C the screen dimming is meant to help with power management. You can chnge to a bright screen under battery power by typing "ps2 br n" at the DOS prompt. If you want the battery saving dim feature enter "ps2 br e" ( the n and e are for normal and economy). By the way since br e Is the default anytime you reset the machine back to factory defaults you will be back to the brightness economy > The screen on my new SVGA TP-755CX dims considerably > whenever I remove the AC power cord and it switches to > battery power.
