KEEPING YOUR SYSTEM RUNNING Copyright 1987 by Barry A. Cole of WLAKUG The top priority of most Kaypro users is reliability. It is absolutely no fun to re-enter the work of several hours or days. A close second is working economically. This includes times when something goes wrong. In this article, I will show you some simple steps to keep your machine running well, and what to do in cases of failure to correct the problem with minimum expense and time lost. Kaypro computers are built very sturdily and are well designed. If some care is taken, they are quite reliable. Failures most often occur due to external causes such as bad power, wrong switch settings on a modem or printer, or bad cables. Another common failure is mechanical wear or mis- handling of disk drives or media. Often a failure is non- existent; it is caused by a mis-interpretation of what has happened(operator error). If you are having a difficulty, here are some rules that will save frustration and money: 1) Confirm that you have a problem: are you trying to do something that the software doesn't support? 2) Always check the simple things first: Is it plugged in? 3) Get as much information as possible about the circumstances of the failure and write them down. What were you doing? Is the power light on? Do you hear disks spinning? 4) Is the problem repeatable? 5) Can you fix the problem by using a different boot disk, program disk, or data disk? (You may have wiped out one disk.) 6) Try to isolate the problem to one component. First between hardware, software, or installation. Then, to a specific component such as B: disk drive. A good test for disk drive allignment is to format and copy a disk from A: to B:. Now Boot from B: diskette in A: and attempt to copy files on itself. Properly alligned drives should show no interchange errors. If you are having trouble printing from a word processor, do a control P from CP/M. 7) If you have no signs of life, try another outlet in your house. Also, check the fuse in the back of your Kaypro. The best way to avoid problems is simple preventive maintainence. Keep your programs and data backed up. Be very careful where you store your diskettes. I do not allow a magnet in the same room. Disks are labeled and numbered always with a felt tip marker. I always replace the cardboard protectors in my disk drives before moving the Kaypro. I leave the doors open when not in use. I run a head cleaner through the drives about every four months or sooner if I see disk errors. I do not detach either power or keyboard cables, ever. Just wind the power cord around the back stakes. Fold the keyboard up and closed without removing the coil cord. You will not tarnish or break the flimsy contacts on the modular phone connector if they are always in the socket. You will also always arrive to find you have all cables. If you do not get the initial message on your screen, but you have the power light on, this is the procedure: 1) UNPLUG your computer from the wall! 2) Open the computer by removing 2 flat head screws from the top and 4 round head screws from each side. Use a large blade phillips screwdriver for this. 3) Lift the top off and place it out of the way. 4) On the top board, you will find many components in sockets(plastic stilts with metal contacts). These tend to loosen and occasionally corrode and discolor. Press down on each in sucession. You may hear them click down into place. 5) Check to make sure connectors are on tightly on this top board, the back of the board underneath the screen, and the back of the disk drives. 6) Replace the cover and screws(2 flat ones on top). 7) Plug the computer in and try again. This is the most common way to save $100 and lots of agony. Finally, get help before you get youself in too deep. If simple things do not solve the problem, don't keep wiping out disks or repeating the same unsucessful actions. Many clubs have members with repair expertise. Seek them out.
