Life on the Run: Notebook Computing 266 When your notebook is running on battery power, the system tray on the right end of the taskbar displays a battery icon. Point to the icon to see how much battery power remains, or right-click the icon and click Open Battery Meter. For more information on the Windows power management fea- tures, see "Making Windows Start Faster," in Chapter 27, "Do-It-Yourself Computer Tune-Ups." Inserting and Ejecting PC Cards Most newer notebook computers make it much easier to upgrade memory, drives, modems, and so on, by using PCMCIA cards (commonly called PC cards ). (PCMCIA is short for Personal Computer Memory Card International Association.) PC cards are small devices that plug directly into expan- sion slots on the outside of the computer. These cards are about the size of credit cards, and most notebook PCs enable you to insert them when the power is on (check your notebook's documen- tation to make sure). It's a little like inserting a disk into a floppy disk drive. When shopping for a PC card, keep in mind that there are three types of cards. They are all the same length and width, but their thickness varies: · Type I cards (up to 3.3mm thick) are used primarily for adding memory to a computer. · Type II cards (up to 5.5mm thick) typically are used to add a fax modem, network adapter, or CD-ROM drive (the drive is connected to the PC card with a cable). · Type III cards (up to 10.5mm thick) usually are used for adding a hard disk drive. Your notebook computer should have one or more PC card slots. These slots also come in three types: · Type I slots can use only one Type I card. · Type II slots can use one Type I card or two Type II cards.
