Can anybody tell me what the lights and switches mean on the console. I have some symbols showing in some of the little windows. With power on from left to right they show: dark dark right arrow underlined % sign vertical bar up arrow up arrow box which could be a screen symbol dark With power off the right arrow shows a battery and all of the others are dark On the right of the screen there are two slide bars one labeled with a shining sun the other like a half moon. Neither seems to do anything >> does your hard drive spin up? any flicker from the LCD? does the floppy seek? what if the battery is removed? Since you have a mono LCD those slider bars just adjust the brightness and contrast. I forgot what the switches do as my L40 is put away. One thing you might want to check is to make sure the computer hasnt been in any environmental extremes. It will not turn on if temperature or humidity is excessive. Once it acclimates to room temp it would function normally. see one of hundreds of computers, or a hot rod pinto at: www.nothingtodo.org
