My problem is that I cannot access the internet via my ethernet port and that I must unplug the power cord to get my computer to boot. System: Power PC G4 Mirror Drive Door OS 10.5.8 80 GB IBM HD (original to the computer) 6 GB Quantum Fireball HD (transferred from my old iMac) Plextor DVDR (replacement for non-functioning Super Drive) Belkin USB 2 card (to connect 2TB external Western Digital HD - currently WD HD is disconnected) Brother HL2240D Laser Printer (connected to USB 2 card) 1,792 MB memory Westell model 6100F DSL Modem PC24-H AirPort Card (I don't have wireless service) My problem began when I was unable to start my computer. I thought that the plug might have been knocked loose and after vigorously jiggling it, the computer started. Even after replacing the power strip, this continued every time that I wanted to start the computer until I realized that the act of unplugging the power cord while jiggling it was allowing the computer to boot. From then on, I would simply reach behind the tower and briefly unplug the cord whenever I wanted to power up the computer. This procedure continued for about a week until pressing the power button caused the power light to go on but it would then go out when the button was released. Discussing this problem with friends lead me to conclude that the battery was probably bad. I replaced the battery but it did not solve the problem. I don't remember exactly what remedied the problem but it was either resetting the PRAM or resetting the PMU. Nonetheless, I still had to unplug the computer to get it to start. The next problem that occurred was that I was unable to access the internet. After much testing of the DSL connection by Verizon internet customer service, we were unable to ascertain what was causing the problem. Fortunately, I had access to a MacBook and I connected it to the modem to verify that the cable, DSL modem and its connections were working. After searching several user's groups, I stumbled upon a posting from someone who believed that resetting the PRAM five times would also reset hardware problems. I tried this and amazingly, it worked; internet access was restored. I did not shut down my computer for about a week and a half but while watching some online videos, I had a kernal crash - this is a problem that this machine has always had with videos. When I rebooted, I was unable to access the internet and, despite many attempts to correct the problem, I have not been able to fix it. I believe that the problem is with the ethernet port. I get a 169.254.24.237 IP address instead of the normal 192.168.1.46 address. I have tried resetting the PRAM singly and five and six consecutive times. I have reset the PMU multiple times in conjunction with and independent of resetting the PRAM. I have inserted and removed the battery multiple times. I have tested the new battery with my volt-ohm meter - it and the original are both fully charged. I have disconnected the USB 2 card. It may or may not be related but I must still unplug the power cord after almost every shut down in order to get the computer to boot. Since loss of my ethernet connection occurred once before and I was able to get it to work, I hope that this is a temporary problem and that you can help me resolve it. Do you have any suggestions? I really appreciate the time and effort that this problem will take. Thanks.
