You see free diagnostics advertised everywhere. This subject needs lots of clarifying. It’s a touchy subject that angers both customers and computer repair shops alike. I’m no exception.

First, lets address the confusion. What exactly is a diagnostic?

… Is it a quick look at your PC and an educated guess?
… Is it a thorough testing of all your hardware and software?
… Is it a thorough troubleshooting and testing service?

The answer is yes to all of these. Therefore the question becomes, what can you expect for free? Do you really expect a repair shop to spend hours working on your PC for free? Do you think they can survive if they do this? Let me ask you this… do you work for free? What would happen if you did? Could you survive?

Now that we’ve cleared this up, let’s ask “What is a Free Diagnostic?” It is one of two things:

1) A “Bait and Switch” scheme to get you into the store
2) A quick look at your PC to get a general idea of the problem, i.e. a quick consultation.

Any honest repair shop will take a quick 10 – 20 minute look at the problem, or even do a simple repair for free, but that is all. However, some computer problems are complex to the point that even an experienced technician will not know what the problem is unless he or she does some in depth troubleshooting. That is not free, nor should it be.

Honest shops will not charge for all their time in these more complex cases if you decide not to do the repair, but they will charge a small diagnostic fee, usually somewhere between $30 to $60 (more for laptops). They still lose money, but at least they get something for their time.

The dishonest shops will pretend they did a diagnostic and then make up a story to get you to do an expensive repair, like replacing a hard drive, motherboard, or reinstalling Windows. This is also what usually happens with Big Box stores (including Office Supply stores). They also use this method to sell you a whole new computer.

In closing, a Word of Caution:

Do not pressure a repair shop to do a free diagnostic. If you do, they’ll either turn down the job and send you away, or recommend a major repair. They can’t spend the time to do a thorough diagnosis unpaid, and will recommend a broad range (i.e. major) repair to cover all the bases, which will definitely fix your computer.

If you’re fair to them, you may get out with a $100 repair. If not, it may be $400. This is more survival behavior than dishonesty (yes, I know it’s a fine line). They have bills to pay, and a need for food, clothing and shelter, just like you.
