| | I will be working on a G4 (I think) tower and the user is saying that the white power light is one when he pushes it but no other power seems to go through to the computer or monitor (no chime sound). He already replaced the 3.6 Volt battery on the logic board and also hit the reset button (CUDA). I haven't worked on these for a long time and have some questions: 1. Can I test the power supply using a 20 pin power supply tester? I did some reading up on this tower and it seems that it will have 24 pins on the main power connector to the board (so 4 extra pins). 2. Are the power supplies the same as the ATX model ones for the PC? I'm steering towards either the logic board or power supply, but hoping there was some way for me to test it first without shelling out a bunch of money for a part I don't need. Both of these cost over $100 when I just checked out the prices. Thanks. |
