i have the same problem as described below:
- I hooked up my old LC 475, and when i turn it on the start chime sound plays, but the screen remains black. The green power light on the monitor is on, and the monitor is properly connected to the computer.
Anyone know whats wrong, or if there are steps I can take to trouble shoot it?
Answers:
- Since you just hooked it up, I assume that it was in storage for a while and disconnected from electrical power. If this is the case, the internal battery probably has been drained down to a very weak level (if not dead). A black screen at startup is a typical symptom of this. You need to get a 3.6-volt, ½AA lithium battery, available from battery retailers, online dealers, and Radio Shack (overpriced - last resort).
- My 475 did the same thing after being unplugged for several weeks. The new battery fixed it.
You get maximum battery life by leaving the computer plugged into the wall at all time. When you store a computer, remove the battery and tape it to the outside of the case.
Finally:
so, recently (only some months) i had replaced the battery with new and everything was ok. I left for vacation in 1st of August and unplugged all the computers and televisions. Yesterday i was testing my powermac g3 beige, i used the macintosh color display and also the new battery from my LC475 and then i reconnected them again. I turned on the LC to test it after my vacation but unfortunately i see only black screen. I turned it off and after 2 seconds i turned it on again but the problem remains. What should i do?
