I was looking at a used G4 450 and it seemed like a great deal except when I went to reboot it a couple of times the monitor on button would start to light up and then go out and it took unplugging the computer from the wall and rebooting to get the monitor to come on. It was on older Sony monitor? Is this software or hardware related. The person wants $150 for a G4 450 / 256/ Zip Drive with a stock hard drive. Seems like a good deal but when rebooting I had a hard time getting the monitor to come on consistently. Is it worth buying?>
This sounds like a dead PRAM battery (available from Radio Shack about $10 or online about $5 OWC etc). Many Macs won't start might not display video with a dead PRAM battery.
Some would start showing video with a dead PRAM battery if you repeatedly rebooted.
The battery generally lasts 3-5 years.
Worth a shot. Morenuf
