EVO D310 and MS-6541 motherboard

I am the looking for the documentation on the motherboard of my computer
EVO D310 µT. It’is a MSI motherboard ref: MS-6541 ver: 1.0 I need to
know the jumper setting and other information. I sought this
documentation at Compaq and MSI, but I did not find anything
I have also minor problems, when I put OFF the computer with the power
supply switch, I lose systematically the setup adjustment (hour, memory,
etc). I replaced the battery, but it is not that. If you have an idea……
I contacted the customer service Compaq, which said to me that this
documentation did not exist, I think that they are not true.
I hope that my English is correct ;o)
Thank you in advance, cordially!
