As you may know, Compaq is a division of HP, so methods of finding the model number are generally going to be the same on either laptop. With that said, I will continue the rest of this article using “HP” referring to both. There are plenty of reasons you may need to know the model number for your HP laptop computer. Perhaps you need to download new drivers, upgrade your hardware or you’re just plain curious and want to know. Here I will show you a few ways that you can find your HP model number.

The Simplest Way:

  1. Close your laptop and Flip it over, so you can see the bottom.
  2. There should be a sticker label on the bottom of your laptop casing with your model number, part number and serial number information on it. In most cases there will be a model series number towards the top of the sticker and the full model number near the bottom. The model number should look similar to G61-429WM or CQ60-111EM.
  3. It is also possible that the label may be located inside your battery compartment or hidden under one of the covers on the bottom of your laptop.

If the label on the bottom of your laptop is missing or unreadable, you may be able to find your model number within your Windows operating system:

  • Once your computer is on and Windows is loaded you may be able to find your model number by right clicking on Computer (or My Computer, depending on your version of Windows) in your start menu and clicking on properties. Your model number may be displayed in the window that opens.
  • If your model number is not displayed there, you may also find it in the system information utility built in to windows. Navigate your start menu to All Programs (or Programs, depending on your version of Windows), Accessories, System Tools and click on System Information. Your model number should be displayed in the information window that opens.

Another option is to use the automatic product finder tool on the HP support site:

  1. Open up your web browser (Internet Explorer) and go to http://www.hp.com .
  2. Navigate to the Support & Drivers page http://www8.hp.com/us/en/support-drivers.html.
  3. From here you can use the automatically find your products tool. Note, it will require you to install their detection software.

If you are still unable to find your model number, you may be able to find third party system information software that could help, but can’t be 100% relied on to be accurate.  If all else fails, contact HP for help.

Symptoms of a Bad Inverter Board

If you are having a problem with the display of your laptop, don’t immediately assume it is a bad screen, it is possible that it is simply the inverter board that is going bad and would be a much cheaper fix than replacing the whole LCD Screen.  If the problems with your display include any of the following symptoms, it is possible that your inverter board is the problem and needs to be replaced or reconnected.

  1. If the video on your screen is faint/dim or blank it is most likely that your inverter board is going bad and needs replacing.
  2. If there is unusually high amounts of excessive heat coming from the bottom area of your LCD screen it is possible that your inverter board has a bad or loose connection and may just need to be replugged in.

The laptop or notebook computer has many parts that contribute to its functionality.   A laptop can be broken up into two main sections, the display or LCD casing and the bottom casing or base.  In this way, a laptop is setup somewhat similar to a desktop computer in that the LCD casing section is mainly made up of the parts that would be included in a desktop monitor and the bottom casing includes the main computer components that would be included inside the desktop computer itself.

The display section or LCD casing of the laptop includes the parts necessary to make the LCD screen work.  The parts included in this section are as follows:

  • Display Bezel
  • LCD Casing

  • Wireless Antenna
  • Microphone

External (visible) Optional Parts

  • Web Cam

The bottom casing houses the main components of the computer.  Parts included in the bottom casing are as follows:

Screen resolution determines the size and clarity of the images and text on your screen. Higher resolutions like 1920 x 1080 make the images and text on your screen look smaller and clearer, while lower resolutions like 800 x 600 make it look larger. The resolutions available for your computer depend on the size of your screen and most screens have a recommended resolution for optimal performance.

Choosing a screen resolution with the wrong aspect ratio for your screen can cause the display to look stretched out or compressed. A widescreen display can have an aspect ratio of 16:9 (1280 x 720), while a full screen displays aspect ratio would be 4:3 (1280 x 960).

Here I will explain how to quickly and easily change the screen resolution on your laptop computer in the Windows XP, Vista and 7 operating systems.

Windows XP

  1. Right-click on the desktop and click Properties
  2. In the Display Properties window that opens click on the Settings tab.
  3. Drag the Screen resolution slider left or right to select your desired resolution
  4. Click Apply and click Yes to confirm the change
  5. Click OK to close the window.

  3. Drag the Resolution slider left or right to select your desired resolution.
  4. Click Apply and click Yes to keep the settings
  5. Click OK to close the window

  3. Click Apply and click Keep changes to keep the settings
  4. Click OK to close the window

Two terms often used interchangeably referring to mobile computers are the terms laptop and notebook.  Many people may just assume that a laptop and a notebook computer are the same and still others may not be sure about what the differences may be.  Well, there are significant differences between the two and in this article, I’m going to explain what those differences are.?

The Merrian-Webster dictionary defines a notebook as “a portable microcomputer that is similar to but usually smaller than a laptop computer”.  Dictionary.com has a similar definition, defining a notebook as “a small, lightweight laptop computer”.

So, what are the actual differences between a laptop computer and a notebook computer?

Size

Notebooks are generally a lot smaller/thinner and more portable, some even comparable to the size of an actual notebook.

Screen

Laptops are going to have a screen size of 14″ – 17″ measured diagonally.  Notebooks in comparison usually come with screens between 12″ and 14″ in size.

Weight

Notebooks are extremely lightweight and often under 6 pounds.  Laptops are heavier and can range anywhere from 2 – 18 pounds in weight.

Battery

A laptop has a battery life of 3+ hours depending on the laptop and a notebook can last from 4 – 5 hours because of lower processing power.

Processing

A laptop computer will contain higher end processors for things like video and audio, while notebooks will be on the lower end of the spectrum.

Optical Drive

Laptop computers will come with some sort of internal integrated DVD and/or CD drive.  Notebook computers do not have integrated drives, but allow external drives to be attached.

Keyboard

Laptops usually include a large full featured keyboard, while notebooks will have a smaller, compact keyboard.

The laptop is designed to be a full replacement to a desktop computer, having some upgrade-ability.  A notebook computer is designed for extreme portability and may only include the most frequently used functionality of a computer, having limited to no upgrade-ability.

Although people will continue to use these two terms interchangeably, you can now see that there are indeed significant differences between notebook and laptop computers.

Heat Sink & Fan

Laptop Heatsink & Fan PictureLaptop Heatsink & Fan

Fans and heat sinks help in cooling down your laptop to prevent overheating. The heat sink is a device often made of copper or aluminum that sits on top of high heat generating chips such as the CPU and draws the heat away from the chip into the fins of the heat sink. A fan is generally installed on top of the heat sink to dissipate the heat that the heat sink draws from the chip. Fans are also placed on the sides or bottom of the laptop casing to help improve air flow throughout the laptop which also helps prevent overheating.

CMOS Battery PictureCMOS Battery

The CMOS (Complementary Metal Oxide Semiconductor) battery provides power to the CMOS chip when the laptop is not powered on. The CMOS memory stores the date, time, and system setup parameters. Without the CMOS Battery, the CMOS would not be able to continuously keep track of the date and time while your computer is off.
