A FIC MB02 battery is a Battery for a NB as shown here

Now this powers the NB but not the CMOS Chip when the NB is turned off the CMOS Battery is something completely different and depending on the make & model of the NB the CMOS Battery can be located in one of several places.

Sometimes it's under a cover on the bottom of the NB and sometimes it's located under the keyboard. Well at least you have to start off by removing the keyboard to get to what you need to remove to change the CMOS Battery.

The actual battery that you want should be a Lithium Button battery with a CR3032 Number on it. Depending on the maker this battery can fit into a Onboard socket or have shrink wrap around it to hold the wires in place and insulate the battery from accidentally being grounded and damaging other things.

To be able to tell you how to change the CMOS or BIOS Battery we need to know the Make & Model of the NB.

Thanks for your post, I am looking for the specific location of the cmos. If you have not serviced this model then you will not know. I have replace one 3 button cell battery located in the hdd bay but would like to know if there is another without tearing the case down.

I have a MB02 notebook that gets the CMOS checksum error and loses its settings every time the battery runs down or is removed. I've identified the "3 button" battery located by the hard drive, but you seemed to infer another battery. Is the 3 button battery not the CMOS battery?
I've been carrying this laptop for quite a while now and it's also having trouble seeing its hard drive now....may be related, maybe not. I've always been very happy with this notebook, but it might be time to strip it and trash it...

The trick with the MB02 is to never let your main battery go dead. Then you won't have any problems. Use hibernate instead of sleep. Get a power inverter for you car...

I recently won a new killer laptop at a trade conference/training session (Compal FL91, T7300, sweet) so my old MB02 is now obsolete to me.

My boss (the actual owner of the MB02) wanted to give it to his son. We found a CMOS battery for it and installed it and thought all was well. (Keep the wire leads off your old battery, BTW. You might need them for the new one)I wiped it out, reloaded Windows, and handed it over. Then about a month later, his son calls and says it's telling him "no OS found" when he tries to boot it up. Same damn problem as before! I told him to do what I always did:

Turn it off. Disconnect the main battery for a minute or so. Try again. Repeat. It eventually will see the OS again.

But clearly, replacing the CMOS battery is not the answer.

I've tried to call and email FIC about a bios upgrade, but was never able to talk to anyone and never received any response whatsoever to multiple email inquiries. FIC is not a company I would EVER do business with again as a reseller, since FIC support is non-existant. Too bad, because the MB02 was a great laptop for me for almost 3 years.
