List Members, GLOD 2400/180 I have done all of Sidney Ho's tricks to no avail. This 2400 was working up unitil an update of HD and RAM so I doubt it died of old age hours of use etc. I got it from a friend. It looks brand new! Tonight I switched back to the original HD and ram to no avail. I unplugged the PRAM battery and have left it that way for now. I even pulled the ram altogether. I tried booting with the screen ribbons unattached incase the screen was holding things up. I was assuming it would boot that way. No luck! I can hear a high pitch low level tone as I hold in the reset button. When I plug in an external keyboard the lights on it flash so it seems the computer is gettng power. After it is plugged in for a while it squeals for a second or two after I unplug it. After trying to reset it with the button sometimes the green light stays on sometimes it stays out. Any help appreciated. Anybody have a working board I might try. One that might be for sale. Any other assistance appreciated! thanks!! Jerry
