I tried to get my portable (520C upgraded with Newer to PPC 167 running
OS System 8.5) going last night and it wouldn't show anything on the screen. So i tried zapping the pram , but i couldn't get it to do that, after numerous tries i thought i was doing it wrong, so i held the option-command=r-p and power key on. it didn't reset the prom but it did show the screen. so i took my hand off the buttons and at the bottom of the screen you could see the screen indicator go from bright to dim and then you can't see anything on the screen. OK, so i did this again but after awhile my hands got tired of holding keys down, so i released the option+command+ r and the screen stayed visible because i was still holding the power+p down. I then released the power and the screen went dark. I redid this and kept holding the power key and p down, after computer loaded everything, i had it rebuild desktop and then attempted a restart. Still no screen. I tried running norton while holding power+p, but it hung up about half way through. I unplugged it and took batteries out, retried it--no screen. I did this and left it unplugged last night, plugged it back in this morning- no screen. You can hear it load and it does load everything because i can hear the voice telling me so. Has this anything to with the pram battery ? I know that the date was off and it has been off before when the computer has set for quite awhile. It also has been setting plugged in for 12 hrs. but still no screen. I was able to mount this on my desktop and run norton on it had a few minor problems which were corrected but still no screen. When doing the option+command+r+p, it won't do it or you can not hear the restart chime. I have tried this also. PowerBook 500 series 1. Remove the AC adapter and the battery. 2. Let the PowerBook sit without power connected for 3 to 5 minutes. 3. Simultaneously press and hold Command-Option-Control-Power On for 5 to 10 seconds. 4. Reinstall the battery and, if necessary, reconnect the AC adapter. any help appreciated. -- PowerBooks is sponsored by <http://lowendmac.com/> and...
