With technology advancing more every day, electronics have become smaller and more mobile. This includes computers. The laptop, or notebook computer is extremely popular these days and many people have them as backup or secondary computers or even as their main computers. The great thing about a laptop is that it uses a battery to power the unti when you are away from a power source so you can literally take your computer anywhere. But in addition to the batteries, there are other parts of the laptop computer that make it work.

You know that another important part of your laptop is the screen. There are many different types of screens and the screen is important since it is the display that will show whatever you are working gon with the computer and you may spend many hours looking at it. Early laptop screens were dim and dark with poor quality but they are very improved today and even come in wide screen and more.

However, you know that the display is not all there is to the laptop. There are many more important parts to the computer. The CPU is very important because it makes your computer work. There are mobile CPUs which keep the machine cooler and prevents overheating. These are great because they also use less power.

There are many great features to the laptop computer. Most of them come with modular (or swappable) drive bays which allow you to remove the floppy drive, the DVD drive and the hard drive. If you want to use different media for storing and saving your data, it is easier than ever to do this while you continue working. You don't even have to shut your computer down.

The laptop is powered by AC power that plugs into the wall. This makes it easy to charge your laptop and charge the batteries. These typically plug into an ordinary wall outlet. The only downside is if you are in a confined space because many have power bricks that take up space. If you plan on using your laptop a lot in hotels and other close quarters, you might want to purchase a more compact device to make it easier.

Ultimately, the most important aspect of the laptop is it's ability to be mobile. This is why the batteries are so important. Most laptops come with one or two batteries or you can purchase an extra battery later. Most laptops batteries last from 2-4 hours when fully charged. Depending on the type of laptop and battery you have, it may be more or less.
