Text: If your Macintosh stops working, try the following suggestions. If it still doesn't work, DO NOT attempt to open the cover -- take the Macintosh to an authorized technician who's been specially trained and has the necessary tools to service your Macintosh. If the screen is dark: Check the brightness control under the left side of the screen. Make sure the Macintosh is switched on and that the power cord is firmly attached to the Mac and to the wall unit. Try another wall outlet. If, when you insert a disk, the screen is bright but the desktop doesn't appear: * Usually an icon indicates the problem or a message appears. The disk may be damaged or it might not be a startup disk; there might be problems with the Macintosh itself. * If the ''sad Macintosh'' icon appears, a hardware problem is often indicated that will require a trained technician. If moving the mouse has no effect on the pointer: The mouse might not be firmly connected to the main unit, or the mouse might not be working properly. (Does it need cleaning?) There may also be a problem with the software; try another diskette. The problem might also be in the Macintosh itself.
If typing on the keyboard produces nothing on the screen: You might be in a situation where typing is illegal. It's also possible that the keyboard connection is loose or the keyboard itself is broken. If you can't save anything on a disk: The disk may be (a) full, (b) not yet initialized for the Macintosh or (c) locked or damaged. It's also possible that the disk drive isn't working properly. Usually a message appears describing the exact problem. If not, eject the disk and see of the Lock tab is in the protect position. Reinsert the disk, select the disk and choose Get Info to check how much room is available. If the clock doesn't keep the proper time: Replace the 4.5-volt battery with a new one -- an EverReady No. 523 or the equivalent). If you can't eject the disk: Hold down the mouse button, then power the system off and on again. This should eject the disk. As a last resort, find the small hole beneath the disk drive. Insert a straightened paper clip or similar small object into this hole and push gently. The disk should pop out. If you've tried all the above suggestions and still can't get any response from your Macintosh, try turning it off briefly, then on again. If you encounter the same problem after restarting the Macintosh, the problem is probably in the disk. Try another disk -- one without any valuable documents on it if possible, so you don't risk losing them. If you have the same problem with all disks, there is most likely a problem with the Macintosh itself. Additional trouble-shooting steps may be found in your Level One Service manual, and also in the section of your Macintosh manual called ''Taking Care of Your Macintosh'' under ''If Something Goes Wrong.''
