To Upgrade or Not to Upgrade Your Laptop
For many laptop owners, deciding to upgrade is usually not as easily accomplished as it is with a desktop PC. There are a few options and tips for upgrading your laptop available. One of the easiest parts to upgrade is the memory. This is the RAM memory the machine uses to run programs. The memory comes on small chips, which are easily snapped into place inside the laptop.
Most of the older models have a cover on the back that is separate from the battery cover. This is where the memory chips are located. As a rule, a laptop will come with two chips installed, which can be upgraded to units that have more memory space on them. You simply need to remove the cover, snap out the old chips and insert the new ones to perform a successful upgrade. Of course your new chips need to be compatible 
with the model of laptop you own.
The newer models make it a little more complex. There is generally still a cover on the back that allows you access to the memory chip, but instead of having both chips in one convenient location, you will only find one under this cover. The other chip is located underneath the keyboard, which makes it difficult for the average computer user to change.
Another drawback to upgrading a laptop is the video card, or lack thereof. You will see a lot of laptops available with a chipset for graphic display. This is not a video card and cannot be replaced by a video card. When it comes to laptops and their video displays, what you purchase is what you will be resigned to working with. If you want a machine with a specific graphic card, you need to purchase it that way.
