The 3.6 volt lithium battery which is used to retain the contents of the CMOS over time may have run out of life. It is a special lithium battery which is trickle-charged by the machine's PSU when it is not in use. If stored away for a long time, without being plugged into the wall, the self-resistance of the battery will cause it to drain down towards zero. The machine will seldom start with a drained-down battery. Also, the cell is nominally 3.6 volts (nameplate), but it is usually 3.68 volts, when new, and it retains voltage that for quite a long time. Such batteries are considered "dead" when the voltage reaches 3.2 volts, but many machines will still work properly, although not with 100 percent reliability, when the battery reaches 3.0 volts. Below 3.0 volts should be considered "really and truly dead". Every battery company seems to make these 1/2 AA lithium batteries. You can get them for $5 or so at Radio Shack. Good "pulls", from used Macs, at electronics recyclers, can also give a decent battery for about $1. -- -- You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
