Hi, I have replaced the battery and still get this message . I hit F1 to continue and nothing. Just stops. No HDD activity. If I hit DEL to enter setup, the same. I have a soltek sl75drv mobo, athlon xp1900 cpu, 512ddr ram, ti4200 graphics. I had reset bios to optimized defaults and rebooted, and it has been like this since. The only other prob was a wrong date issue. Wassup? This machine has been going fine for several years, and has had no recent hardware changes/upgrades.
