[comp.sys.ibm.pc.hardware] 80-Data Motherboard Question

I have an 80-Data 286 motherboard-- a Turbo-12 relabled Turbo-10.

Can anyone tell me what the jumper marked "charge" is for?

The motherboard works perfect, except it will not keep it's setup.  Every-
time it is turned on it says "CMOS Ram Checksum Error" (or something like that)
and asks if I want to run the setup program (I am using an AMI BIOS). 

The battery is good, and connected correctly.  It works fine as long as I dont
turn the machine off.  If I just hit RESET it will boot correctly.

I have also used the "Landmark Setup" program (lm-setup.com) with the same 
results.  

I was wondering if the "charge" jumper had any effect on the battery and thus
the CMOS RAM.   Any ideas?

I'm not sure speaking about it, becouse the fact that you haven't specified the type of Battery (on matherboard, external, Lithium, Alcaline).
A lot of matherboard can use many different type of battery, and if you have problem with one, you can change it.
Some time the re-charger will not work after years of well-known work.
So, you can only try with a non-rechargeable battery pack.
