Specs: xp
I was trying to replace the cmos battery onmy Dell Inspiron 8000. When I finally got to the old cmos battery I found it was corroded and also on the holder. I couldn't get the battery connector out of the Ziff holder. I ended up pulling the ziff connector off the board. Could anyone tell me how I can connect the new cmos battery? Thanks

Are you talking about the reserve battery?

You will have to obtain another holder then do some improvising. The following website link is NOT about your product (it's about a piano keyboard) but it will give you some idea what you are up against:

Ignore the mention of "drilling" - not practicable on double sided boards.

It is difficult to say much more without seeing a picture of the situation you're presented with.

Always pop back and let us know the outcome - thanks

You will likely have to remove the motherboard so that you can access the backside, desolder the battery holder (or what's left of it), purchase a new battery holder, & then solder it in place.

And do the removal and soldering in of the new holder "very carefully", as one can easily overheat a cct. board and "upset" neighbouring cct. tracks and components.

If you're not really adept at fine level soldering, perhaps locate someone who is; and ensure as best you can that they do know how...

Thanks for the replies. I don't see a way to put a picture on here? Otherwise I would show what the holder looked like. This isn't on the main board. It's underneath the palm rest. The batteries had been in there many years in storage. There was corrosion on one end of the battery pack. The holder itself had green colored stuff on it. I couldn't get the battery clip out of the old one. Eventually the wires came out. The 2 parts of the holder were fused together by age I guess.Finally the whole ziff holder came off and apart. I'm a real beginner with the insides of a laptop. I can solder music cables etc but this is very tiny. I just need it for a few tasks so I hope I can get it going without too much cost.

The green is corrosion and must be completely removed or it will cause future troubles.

You could post your picture on this free website:

They then give you a special link (URL) which you paste on here and we can then access it.
