dimension 4550 bios battery help.

My dell when i unplug it and plug it back in won't keep the bios settings. I replace the battery with a new one and the jumper is on normal. But it will tell me my cmos battery voltage it low but it's brand new. I can't figure it out. The jumper said normal or setup. I can't even find a service manual for it. Well thanks for any help i can get.

Hi GWB21471

Thanks for writing to us.

After changing the battery is the BIOS saving the settings?

Have you replaced it with the same part# as the original one. If yes, then possibly we are looking at the connector on the motherboard is faulty.

Do provide us your system tag#, email address and name via private message,by clicking on my name in blue and then select send a private message

Sorry i haven't gotten back to you about this but i was on vacation. I took the motherboard out  and tried to trace the positive form the bios battery and where it soldered to the motherboard has power but from there it doesn't. I check where the jumper is to clear bios and i have no power there. The little coin battery with in a couple of day after putting it on the battery socket. The computer will keep it settings with it kept plug in but once it's unplug  everything gets wipe out in the bios. I seem can't find a diagram to show me what to test to see   where the power stops. Can i put a external bios battery on it. Thanks for the help.
