Recently my fren told me that he is having problem with his mb. He is using Tomato's PIII-MB BXv98-CU/V693 with VIA's chipset. His problem is that the CMOS battery discharges very quickly within few days (4-6) days. I've analyzed the mb and found that the CMOS battery is discharging. A 3V battery discharges to around 2.65V within 4 days. Can anybody know what is the cause of this unusual problem. Is changing MB is the last solution? plz suggest.
