CMOS Battery??? What type/size is this?

[Byrus]

All,

I've been plagued with this EFA Corp Pegasus I (E5TX-AT) motherboard for a long time now. Among the myriad of other problems I am having, the clock looses time contantly. Looking at the battery on the board, it doesn't seem like it fits correctly, so I want to make sure I get the correct one.

Problem is, the MoBo manual makes no mention of size/type of battery that is supposed to be in there. Is this some kind of standardized thing (I wouldn't think so)?

Any help appreciated.

If this is the battery that came with the unit then i would suspect that it is the correct one, should be the size of quarter you can pick one up just about anywhere.pretty much any place like walmart,Echerds,a good local computer shop.

Hello Byrus,
I'm sure you are aware that there are quite a few different styles, shapes, and sizes of CMOS batteries out there. Trying to nail the exact one for your board without having it in hand would be very difficult.
Unless someone else here is familiar with that exact board, I'm not sure we could get the exact model# battery. Have you tried pulling the battery to see if there is a model# printed on the MOBO? (Replace with #xxooyy)
Or how about their site?
How bad is the time loss? Does it loose time in BIOS settings or just windows? I have 5 machines at home and I know that 4 of them do not keep the correct time (in windows) with varied differences. The 5th one is my teenage sons and we just set it up and I have not seen it since then so I'm not sure about his.
Good luck

Well, the time loss is completely random... I guess I should elaborate a little... I really should say time and date, because I'll reboot the thing and it suddenly things it's 1999 again. And sometimes nothing happens at all.

I'm hesitant to get a battery like the one that's in there, as it doesn't seem to fit well, slides around, doesn't seat properly, etc.

As far as a replacement ID on the MoBo, you can forget it... I was in there one day trying to make sure that battery was inserted properly, and I couldn't even find a (+/-) indication anywhere there... Every single toy, flashlight, camera, appliance, etc that I have ever owned has this indication on it...

I did send an email to their tech support, but I wanted to get the battery today (you know how it is) not next month some time.

Yoda, where'd you get the scoop on the MoBo?

Some of the older BIOS chips weren't programmed
to be year 2K compliant. May need a BIOS upgrade.

Is there a sticker of any sort on the BIOS chip?

Just a thought.


Luck.

I think Ranch is on to something with the BIOS update.

I would bet a dollar that for that particular Socket 7 mobo, the battery is a CR 2032. It should go in face down.

Rule out the BIOS issue... It's been flashed since 2k hit.

Does "Face Down" imply + side down then?

Well, now... looks like you get $0.50...

The Battery that *was* in there, is in fact a CR 2032, however, placing it "face" down caused my PC to not boot, and after flipping it back over, we get a nice CMOS checksum error...

Well, I guess this battery was working once upon a time, so there should be no problem putting another of the same sort back in there.

Hmmm, OK, so what I meant by 'face-down' is that you should install the battery in there so that you can actually read the numbers "CR 2032" on it. Don't know which side is positive though. Never really gave it a thought.

After you install the battery, boot up and go into BIOS setup. Choose Fail Safe Defaults, or Defaults, or something like that. Continue to boot, make sure everything is working correctly, and then you can go back into BIOS on the next boot up and tweak if necessary.

Good luck.

CR2032 is the most common for Socket 7 boards, and most I've saan have had the + facing up, which also leaves the CR2032 stamp visible, as mentioned above.

I fhtat one does not fit right, I think you'll either have to wait for tech support to reply or find someone with the same board.
