Dell optiflex computer fails to start after motherboard battery replacement

[Rixter]

As concisely as possible: my computer clock stop keeping time. replaced battery with correct battery. It refuses to start again. all connections okay. All I get is a faint yellow glow at the start button.Started fine before i replaced battery.

I've seen them dead out of the package...try another one.
You did have all power unplugged when you did this correct ?

Yes sir..would a dead mother board battrery keep a computer from starting?

[patio]

Not normally...no.
But that's where you started so let's re-do it...
Also double check all connections inside the case while you are in there.

Also check you didn't set the CMOS Clear jumper and forget to put it back where it belongs.

I will double check..thank you..The most important thing is that i have a working computer..the one i'm using now. i have very much material on the one that has crashed. i think maybe i should remove the hard drives from crashed computer and put them in this one but that might be too complicated for me. I will do as you say..buy a new battery. Is there any other way..any other possibility if you have a hard disk in your hand..to buy something that cab be used to move the information to a place where i can find it.?? thanks so much for any advice.
