Yet another ps question maybe
I am currently looking at a compaq presario model #4420CA for a
friend. When I turn the power switch on, nothing happens, the green lights in the front of the tower do not come on at all. I have replaced the power cord,and checked the switch to no avail, I have replaced the power supply with my power supply from my HP 6746C computer and it is still not working. Could someone pls let me know if this means that my mother board is bad and is it feasible to replace it. If anyone had any other ideas on what the problem may be, it would be much appreciated.tks scott |

For what its worth, I've had computers with symptoms similar to yours that I
fixed by replacing the cmos battery. "scottycj" wrote in message .. . I am currently looking at a compaq presario model #4420CA for a friend.

you probably have a "proprietary power supply" on that compaq that can
not use normal psu's and I'm not sure if the HP one you tested it with are the same. possible? they (proprietary power supplies) have different wiring so there might be a chance your old psu is bad. I went several rounds with some power supplies some years ago just like this problem. on some mb's, I could jumper it so that the power supply was switched on all the time. but I do remember on some rewiring the molex connector. check this link for help http://forum.ecoustics.com/bbs/messa...29/120374.html |
