Apple 145B manual Power, Battery is draining too fast

The computer exhibits odd behavior, such as many unexplained system failures.

mA common cause of unexplained problems is multiple System Folders on your computer’s startup disk. The System Folder that the PowerBook is using to operate is marked with an icon. Use the Find command in the Finder’s File menu to locate any other System Folders, and throw them in the Trash.

mYou may have a virus on your hard disk. Obtain a virus- detection program, use it to check all your disks, and eliminate any viruses the program finds.

mYou may be using a program that’s not compatible with your computer’s system software. Check the information that came with the program or contact the manufacturer.

mYou may have added a control panel or system extension that is incompatible with other programs you use. Restart the computer with the Shift key held down until you see the message “Extensions off.” If the problem does not recur, remove any such items you recently installed.

Power

mTurn down the screen brightness, turn off virtual memory, move the Battery Conservation slider in the PowerBook control panel to Maximum Conservation, or work with the power adapter plugged in.

mYou may be using an input device (such as the mouse intended for desktop Macintosh systems) not designed for PowerBook computers. Make sure to use only low-power input devices.

mIf you aren’t using network services, you can also save power by turning off AppleTalk in the Chooser.

mYour battery may need to be discharged and recharged completely. See Chapter 7.
