But it can give up a lot earlier, or later. The PRAM battery provides a bit of power so that your Mac can remember its settings, such as your preferences and the date and time, while it is turned off. Sometimes an early sign that the battery is going bad is that your date and/or time will become incorrect, but often the first sign that the battery is dead is that your Mac won't startup. The PRAM battery is a small cylindrical lithium battery that looks like a short AA battery. In fact it is colloquially called a "1/2 AA." It is located on the motherboard and it snaps in and out just like a AA battery in a toy. Your Mac's PRAM battery is probably a light purple and black. Tadiran # TL5101 Lithium Battery 3.6 Volts 0.97" long x 0.56" diameter Other World Computing is a good source for PRAM batteries. They stock them for only $5: http://eshop.macsales.com/item/Newer%20Technology/BAA36VPRAM/ $7 including shipping http://tinyurl.com/39ur2b You can also get one (for a bit more money) at a local Radio Shack (you can't purchase them online from Radio Shack for some reason ). $15 Catalog #: 23-026 <http://www.radioshack.com/product/index.jsp?productId=2104707&cp> ___________________________________________ Randy B.
