Cracked or Broken Laptop LCD Screen Repair Prices Drop

January 21, 2012 By Leave a Comment

Need to fix a broken laptop screen but are afraid of the cost?  Fear not!  Prices for replacing laptop LCD screens have dropped dramatically over the past year.  With the proliferation of laptops, prices for screens have dropped below $100 for many models.  Even the larger, High Definition screens can be as low as $125.  Compare that to $250 plus, just a year or two ago.

That means it’s now worth fixing your laptop versus replacing it.  With labor, the total cost of most LCD replacement now averages around $230 – $250 at most Tucson computer repair stores, such as our shop.  If your laptop is less than 3 years old and is a mid-to-high-end model, it’s definitely worth fixing.

These prices are for refurbished screens.  New screen prices are about $50 – $100 more.  We usually recommend going with a new screen for higher end laptops less than 2 years old.  For all others, refurbished is your best bet.  We’ve been doing laptop LCD screen repair for several years, and have had very good luck with the refurbished screens.

Free PC Diagnostics: Confusion and the Truth

December 10, 2011 By 1 Comment

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.

Laptop Repair: Overheating Issues

December 7, 2011 By 3 Comments

Does your laptop shut down on its own?  Does it get so hot you can’t keep it on your lap?  Does the fan scream or make grinding noises so loud it scares you?  If so, you could be having overheating issues.

What’s happening here?  First of all, if the processor (CPU) gets too hot, the laptop will shut itself down to protect it from burning out.  There are other reasons for unexpected shutdowns, but this is a major one.  This can also happen if the video (graphics) chip overheats.

This could happen for several reasons, but the major causes are as follows.

The fan is clogged or is going bad: 

It could be gunked up with dust or pet hair, preventing the air flow of the fan.  Sometimes the bearings on the fan go bad, resulting in grinding noises.  Dust and hair can either damage the bearings directly, or block the fan from rotating freely, which in turn can damage the bearings.

The Thermal Compound on the CPU has dried up and/or cracked:

In this case, the laptop will shut down on its own, or the fan will run really fast.  Why?  There is a thin film of heat conducting “grease” that sits between the CPU itself and the surface of a metal plate called the “Heat Sink”.  It’s like a radiator and has thin metal (usually copper) fins to help dissipate the heat from the CPU.

The thermal compound forms a seal that ensures full contact between the CPU and the heatsink, so that it efficiently pulls off the heat.  Over time, it can dry up and crack, breaking that seal.  Old, dried up compound also loses it’s ability to transfer (pull off) heat from the CPU.

Repair & Maintenance Options:

1. Get a can of air and blow it into the cooling vents of the laptop.  You’ll be surprised at what comes out.  If you wait too long however, there may be so much caked up in there, this won’t help.  The laptop may have to be opened up, so a technician can get in there and clean it up.

2. Broken fans have to be replaced.  This is not usually a big job, and the fans are cheap.  On some models however, the fan and heat sink are an integrated assembly and you have to replace the whole cooling system.  This is a bit more expensive, but still not too bad.

3. Remove the old thermal compound and put on a fresh layer.  This costs a little more, as you have to remove both the heat sink and fan, so you can get to the CPU.  When we do this, we use a higher quality compound than what the laptop came with.  We use a silver-impregnated compound that makes the laptop run up to 10 degrees cooler than standard ceramic compounds.

We can help you with these, or any other Computer and Laptop Repair issues.  If you’re reading this post from outside our website, click this link to our Tucson Laptop Repair website to learn more.

Online PC Tuneup Sites – Most are Useless or Even Scams

November 30, 2011 By Leave a Comment

What’s the deal with these sites that promise to double your PC’s speed with just the click of a button?  Yes, we all hear the commercials where someone is ecstatically happy because his or her PC is running “faster than ever”.  Oh really?

You may think I’m posting this because I’m a repair technician and get angry when I hear these.  Well you’re right, but not because I’m afraid of the competition.  I’m angry because these claims are mostly scams that take advantage of people.  You can speed up your PC by downloading any of a wide selection of free utilities, versus paying these bozos.

Now I’m only talking about very basic cleanup processes on PC’s that are basically in good shape, because that’s all that these sites or the free utilities can handle.  A badly under-performing PC that locks up and freezes, or gets Windows errors cannot be fixed like this.  These sites dupe people into thinking they will, and that angers me even more.  Then, they start charging extra fees for more extensive procedures.

Why not Clean Your PC Yourself, for Free?

I recommend a great little free program called “C-Cleaner“.  It’s very popular among PC Technicians and is part of our arsenal of standard tools.  You can download it from the “Resources” tab on our Saguaro PC Tech website, or at Download.com.  There’s a paid version too, but you don’t need it.

To clean and tune a really slow PC suffering from lockups and errors, several procedures are required, including checking for viruses and spyware, checking the health of the hard drive, removing outdated programs, installing Windows and driver updates, etc.  The list goes on.

Again, these sites will charge for more work, but many of these procedures can’t be done very well, or even at all via on line support.  Don’t waste your time or money.  You may find that taking your PC to a reputable local repair shop will be both cheaper and more effective.

Top 10 Simple Privacy Tricks Anyone Can Do: Tip 4

June 17, 2011 By

Use Temporary Credit Cards for Safety and to Avoid Repeat Billing

This is a great way to add some extra security to your online purchases.  It’s also a way to avoid repeat billing from sneaky vendors (like antivirus subscriptions) or  overbilling.  Most card issuers have them (usually called “safe shopping” cards or “gift cards”).  While the gift card type of card simply runs out, the safe shopping cards let you do things like choose the card’s spending limit, expiration date, and more.  That way, you can make sure that automatic billing doesn’t kick in unless you absolutely want it to.  Vendors can’t charge you if there’s no money left on the card.  Another security feature is that if anyone ever gets a hold of your account information, all they can get is the amount of the balance on the card, or the amount of the spending limit (if you have that type of card).

Top 10 Simple Online Privacy Tricks Anyone Can Do: Tips 1-2

June 7, 2011 By

Tips 1 & 2: Passwords and Security Questions

These first two tips go hand-in-hand, so make sure you use them both.  Read on……

 

1. Create Secure, Easy-to-Remember Passwords

Secure passwords are the best, but not if you can’t remember them.  Most of you already know this, but are you implementing it?  There are a lot of tricks to creating easy, memorable passwords without making them easy to guess.  You can research this on Google, but I’ll give you a few ideas.

1)  Don’t use the same password for every website, especially banking sites.

2)  Alternate UPPER and lower-case letters, as passwords are case-sensitive.

3)  Use special characters, such as #,%,@, or !. Either add them or replace a letter with one of these characters.

4) Use a common base password (like a pet’s name), then add pattern of numbers that means something to you (like your kids’ birthdays).  Or perhaps add the initials of the website it’s for.

Example:  If your cat’s name is Muffy, your kid was born in 1964 and the password is for Yahoo Mail, you can use MuFFy1964YM.  For a Wells Fargo password, say your birthday is May 5, 1945.  You can use MuFFy1945WF.  Get the picture?

5)  Shift your fingers up one row and to the right (or the left, since they don’t quite line up) on the keyboard from the actual letter you want.  For instance, instead of “muffy“, type k8tt7.  Use whatever rule you want, but stick with one rule, so you don’t get confused.

 

2. Security Questions.  Keep them as Private as Your Passwords

Strong passwords are important, but they’re useless if your security question is something anyone can answer.  Most websites have ways to recover or reset your password if you forget it by using security questions, also known as “challenge questions”.  When you answer these correctly, the site lets you change your password, or will email it to you.  What would happen if a hacker, coworker, your kid, or an angry “ex” knew the answer to this question?  I shudder to think!

Instead of going the traditional security question route, you could use a formula to create a memorable, yet indecipherable security question.  For instance, you could use word association to make the question easy for you, but hard for others, for example:

  • “What’s your mother’s maiden name?” could be answered with your favorite Iron Maiden album instead.
  • Put in your mother’s birthplace when the question asks for your birthplace.  Get the picture?

Here’s another trick, but it’s not available on all websites.  Some sites let you create your own privacy questions.  If they do, definitely go for this option, as it opens up a whole world of options.
