165955 2003-08-07 03:03:00 Hi Folks,

I unfortunately did a silly thing with my PC this morning. Unpatient as I can be at times, I went into some troubleshooting!

Well, the problem is that, when I went to lift the CMOS battery up from the battery, the clip which holds the battery in position, broke.

I can still get CMOS, but cannot use the keyboard to enter BIOS.

Any suggestions or remedies. Is this the end for me?


Sincerely
Julius Caesar. (Romantic Emperor)

165957 2003-08-07 03:21:00 just solder a new battery holder in.

however you should still be able to use a keyboard even without a bios battery, sounds like you have other problems as well.

what type of keyboard, usb?

I could try that...but umm.. I don't know much about soldering. sorry!

I don't think that I have more problems as it may sound as though I do. I just think that I need to get this battery back into its slot. At the moment, the pc is on its side. (Its not a Desktop PC Case)

As for the keyboard, I could try the other one, which is USB and PS/2
The one which I was using is only PS/2

165959 2003-08-07 04:26:00 Umm. :_| This is not such an easy repair. You could "probably" remove the holder and replace it. However that's a major operation. And although it would "probably" be successful, those boards are not intended to be repaired. There are multiple layers of circuit tracks, joind by plated through holes. It is possible to destroy the plating in a hole while desoldering. I don't think anyone would guarantee the results. :D

However, all is probably not lost. The battery makes contact at the edge, and at the centre. If you haven't damaged the socket too badly, it should still make contact. All that remains is to hold it in. Superstick packaging tape comes to mind, but anything which will hold the battery down in the socket will work. The ideal would be something with spring (foam tape might work -- stuck to the battery, under the tape).

How about Cellotape or even Superglue the battery at the bottom.

Meanwhile, this could be very bad advice, but the cellotape idea could convieniently be the solution to your problem. (I stand to be corrected)

If you do decide to superglue the battery to your motherboard, then just hope that your battery doesn't die out in front of you within the next month or so.

nah....peice of cake......if you have the gear ;-) any tech could do it. the curse is having to pull the mobo out of the case and then reinstalling it.

165962 2003-08-07 06:29:00 They can actually be unsoldered as tweak'e says. fairly easily if you are familiar with an instrument type soldering iron.
You can get a battery holder from a junked motherboard.

It may be possible with a pair of IC type side cutters to snip the old holder off and just solder to the stub ends. Or even solder leads to the stub ends and then solder the holder with it taped in a convenient remote place, taking care that it doesnt short out anywhere.

Note you dont have to lift the battery clip much if at all, there is usually a piece of plastic cantilevered opposite to the clip, so that if you push down on it the battery can be slid out of the holder

You could get an external battery that plugs into the old header pins that some motherboards had and if your motherboard does not have an "enternal" battery connector cut the plug off the batery and solder the wires onto the button cell holder.

I have done this before, not tidy looking, but it worked.

165964 2003-08-07 07:12:00 Just another thing I forgot. The holders with a spring clip make contact through the clip, it's the holders without a clip that contact on the sides.
Ughs way, to solder to existing connectors is probably the best way for a "non-tech" to go.
You hopefully wouldnt even need to remove the broken holder. There may be enough of the end of the clip to solder to, and it should also be easy to solder to the centre contact.
