Liquid Spills – Dead on Arrival or Repairable Problem?

Tuesday, December 14th, 2010

Liquid spills are amongst the most damaging issues you can have with any electronic.  After all, water (and therefore most other liquids) conduct electricity very well, bridging components together that very much don’t want to be bridged.

Of course, the easiest way to avoid this problem is to simply keep liquids away from our computers, especially laptops that are more easily damaged.  Lets face it though, we all grow a little lazy after a while when it comes to keeping liquids at a great distance, myself included, and that glass of water, or can of soda slowly creeps its way closer and closer to our beloved laptop.

You’re in luck, though, as most spill situations are solvable.  However, a few initial steps need to happen to lessen the chance of permanent damage:

  1. Force shut down the computer by holding the power button until it turns off.
  2. If the system is a laptop, remove the battery so that power no longer can go to the system at all
  3. Bring the system into a repair shop that is comfortable with liquid spill cleanups.

In most situations, the liquid itself does not cause any damage.  However, especially with liquids that have sugars in them like juice or soda, the sugar can crystallize and create corrosion on the system, which can cause conductive bridges between the small components on the boards inside the computer, which can then cause a short, or can burn components when the power is restored.

If the system is properly cleaned before this is able to happen, then you can save your system from what would seem to be certain doom.  If you cannot, most of the time the damage to the system board is unrepairable (or at least not within a reasonable budget to repair) and would result in a need to replace a very expensive component.  Upon reaching this point, you can have your hard drive removed to recover data, and move into a new system.

Google Chrome OS and Smartbooks

Thursday, November 4th, 2010

With the phenomena of netbooks and now more recently tablet computers (not the old school flipscreen Windows tablets, but the iPad and subsequent competing platforms) we find ourselves more and more drawn to smaller devices that can fulfill out daily computing needs.

Nowadays, 90% of what we do is on the internet. Think of a time recently that you used your personal computer otherwise. Not too much there, unless your a gamer. Most of us are avid You-tubers, Facebook fanatics, twitter fiends, or just your basic email users. Of course, you can use your home computer for this, but more and more lately we are being driven towards smaller, more portable devices. Smartphones like the iPhone, Android phones, and soon the Windows 7 Phone. Tablets like the iPad, the new Pre tablet HP is working on, and soon some Windows 7 Tablets. These products are all innovations in their respective fields, and have changed the way we look at computer.

Google, however, is creating a paradigm shift, rather than just an innovation.

Introducing Google Chrome OS, which is rumored to become available this month, is a new netbook / tablet operating system that changes the way that your typical computing is done. Take a look here:

If you have used Google’s Chrome web browser, you should relatively familiar with the look and field of Chrome OS.  This being one of Google’s primary goals, is to make their operating system easy to use and intuitive, like you had used it before.

Start up time is huge, with a total time of under 7 seconds on average, you can be up and running in no time.  Sure beats the minute I have to wait on average to start using my system at home.

The biggest feature is what will be considered the paradigm shift, and that is that items you work on while on your computer, such as documents, spreadsheets, or pictures aren’t actually saved on your computer, they are saved in the Cloud, online, instantly as you work on them, making them available to you at any time you can access a computer.  This benefits us in several ways: first, if your computer is lost or stolen, not only is the data incredibly difficult to hack, but you can be up in moments with a new machine simply by logging in.  Because your information is stored online in the Cloud, it is retrieved with your account, and you are up and running.  Second, this eliminates the need of massive amounts of storage on your computer, which allows us to do away with the old mechanical hard drives which have a high failure rate in laptops and netbooks and move into the newer, solid state technology, which is faster and has no moving parts.

If you find yourself a little more interested in this technology, go on You Tube and search Google Chrome OS.  There are some great technical demos that will show you what you can do with these devices.

Laptop Screen Issues

Thursday, October 28th, 2010

I’m sure we’ve all seen atleast one instance of a laptop screen issue, whether it be cracked, no longer lighting up, or have a glitchy image that’s solved only by physically moving the screen. Of course, fixing these problems would be less daunting if they could all be solved by replacing the LCD. But what happens when you replace the LCD and the same problem is still happening?

There are typically four main components that help to display video on your laptop. The motherboards video output, the LCD ribbon cable (attaches the LCD to the motherboard), the inverter board (inverts DC power to AC power), and the LCD itself.

Here are a list of some common problems that can be associated to each of these components. Keep in mind, the same issue can be caused by different components, and the only way to test these is to work with some known working components.

Motherboard: Artifacted images (can be duplicated by plugging in an external monitor), no display, no backlight, wrong colors in the screen, shifted image, fuzzy image. — Some of these issues can be resolved by simply updating video drivers.

LCD Ribbon Cable: Distorted image ( can be partially remedied by moving the screen around), flashing connection, no backlight.

Inverter Board: No backlight, red hue in image.

LCD Display: No display, no backlight, red hue in image, flashing connection, distorted image, shifted screen.

Use some of these guidelines to help discover the source of your issue. Of course, the easiest way to determine the source of display issues would be to bring your system in to ITZ Solved for a free diagnostic.
