- Macintosh: What to do if your Macintosh stops working
- If your Macintosh stops working, try the suggestions below. 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 doesen'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 dosen'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 re-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 troubleshooting 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".
