I seem to be having to replace the mobo battery about every 4 weeks....it is a cr3202 lithium..3v... is it or is it not recharged by the psu while the system is on.?.. and if not then something is a drain...somewhat slow...on the battery....I went on a another forum (totalbf2) and got varied responses to that question with no real answers...I believe it is NOT rechargable, and that it should last at least 3-5 years, as the main drain is the cmos clock...so then the mobo is bad i suppose? it is a relatively new ABIT Fatal1ty An8 Sli 939..... I have not tested that batteries themselves to see if they are dead, I just get black screen lockup...go to Bios and the date is off and fluttering?.. when i reset cmos and replace battery then everything is fine for until the next episode........Help?
