The Laptop Repair Workbook
An Introduction to Troubleshooting and
Repairing Laptop Computers
Printing instructions for a two sided printing you can put in a binder.
In Adobe Acrobat, when you go to print, you should see a menu with a box
labeled “Print Range.” Check off the radio button that says “Pages from” and
enter “1” to “189”. Right below that in the “Subset” box choose “Odd pages
only”. Once the pages are all printed, put the stack back into the printer, with
the printed side turned down, so it won’t get printed on. Note that printing
always starts at the top of each page. When you go to print again, check off the
radio button that says “Pages from” and enter “2” to “190”. Below that in the
“Subset” box choose “Even pages only” and put a check in the “Reverse Order”
box. When it’s finished, go back and print page 191 by itself. If you want to
play it safe, experiment with printing the first 4 pages of the book until you get
the technique right. If you have a decent quality laser, good paper and no
jams, it should come out printed properly and you won’t even have to shuffle
the pages to get them in order.

Before We Begin Troubleshooting
The author of this book is the proud owner of a 1986 Dodge
Omni that was purchased new and has never been taken to a
garage for repairs. But laptops aren’t cars and they are rarely as
cost effective to repair as desktop PC’s. A twenty or forty year
old car in good operating condition is just as serviceable as a
new car and may even get better gas mileage. But a ten year old
laptop isn’t going to run the latest Microsoft operating system or
even the previous version. Computers are no better than the
software they can run. You’re going to need an up-to-date
operating system if you are a mainstream user who wants to run
the same software you use in work or the current year tax
program. A laptop computer that cost as much as a new small
car in the 1980’s isn’t worth a gallon of gas today. Think of
computers as software appliances. Unfortunately, laptop
computers are among the shortest lived appliances found in the
American household today.
If you make an appointment with a doctor for a health
issue, the first thing you might expect to hear is, “So, what seems
to be the problem today?” This is the most important part of the
diagnostics process for a good physician, listening to the patient
describe the symptoms and asking some follow-up questions to
probe deeper. The patient who responds, “I don’t know what’s
wrong with me” might get a blood test or a psychiatric battery
but is unlikely to walk out of the office with a cure. When it
comes to diagnosing your laptop problems, the laptop is the
patient and you are the physician. The laptop usually can’t
describe its symptoms, so you have to be a keen observer of
laptop behavior if you want to nail the problem your first time
out.
Some health issues, like puncture wounds and broken
limbs, manifest themselves in an obvious manner so there’s no
difficulty with the doctor or patient diagnosing the problem. The
same is true if you’ve broken the hinges off your laptop, if the
battery burst into flames or if you knocked your orange juice
over the keyboard and it stopped working. The solutions are
generally both obvious and expensive, and since laptops aren’t
family members, replacement is often the most sensible
solution. But the majority of laptop symptoms, at least at first
