Question

Hi Howard, Thank you for your help. I am used to change the batteries of my computers. However on this motherboard Aopen VKM400Am-S, I cannot find any battery. The only metallic disc about the size of a battery is a part of a square chip. The following reference is written on this round element : VIA vt8237 0416CD CHINA 2IA29F2600 Obviously it is not a battery.Is it possible certain motherboards do not have any battery ?Hoping your answer,RegardsAlain
