Laptops are different from desktops in the following ways; Power supply: As desktops can be plugged in an outlet in the wall (AC Power) so can laptops with an AC adapter. But how a laptop is different from a desktop is that it is portable because batteries can also power laptops. The batteries are rechargeable; lithium, nickel-cadmium, or nickel-metal hydride. Display: Also like desktops, laptops have some type of LCD display screen. Modern Laptops have 800 x 600 pixel resolution. This gives it a very clear screen and anything less should be avoided. Input Devices: On a desktop computer you usually use a mouse and keyboard to enter data and navigate. With laptops keyboards are built in but since they are portable so they don"t have a mouse. Instead they have one of three input devices in place of the mouse. A trackball, rotating the ball allows you to move the cursor. A trackpoint allows you to push your finger over the point to move the cursor. Lastly, a laptop may have a touchpad that you move your finger across to move the cursor. Docking Connections: Many laptops come with a docking connection to make it more comfortable to use at a desk. You just plug your laptop in and use it as a desktop. The docking station comes with many peripheral devices: full size computer monitor, full size keyboard and mouse, disk drives and printer. Thanks for reading A1-Computers

Laptop computers are the perfect choice for people on the go. They offer all of the features of a desktop personal computer with the added benefits of portability. There are many kinds of laptop computers to choose from. When choosing a new laptop computer, look at the battery size, the memory and the physical size and weight of the computer.
When looking at new laptop computers, one thing you should consider is the battery size. All laptops come with a rechargeable battery. However, each laptop is different. Some batteries are designed to last longer than others. In general, a laptop computer battery will only last around two hours before needing to be recharged. As the computer ages and the battery gets older, the battery capacity will decrease. After approximately 1,000 charge and discharge cycles, the battery can no longer hold a charge. This usually equals about three years of normal laptop use. If you do not use the laptop often, the battery will become ineffective in about four years. If you plan on using the computers’ battery over plugging the laptop into the wall, the best piece of advice is to look for a laptop that has the largest battery life. Also, it is recommended to keep the laptop computer plugged in when possible so the battery does not constantly have to recharge itself. A second battery can also be purchased to use when the first battery runs out of charge.
Memory size is another key factor in choosing laptop computers. Memory size also varies from laptop to laptop. The amount of memory you purchase will depend on what you are using the computer for. If you need to store a vast amount of information on your computer or need to store pictures or video, you will need a larger amount of memory. Most new laptop computers come with a large amount of memory space already installed. Look for a minimum of 512 MB of memory. If you will need more memory space, check to see if the new laptop you are purchasing comes with expansion slots for more space.
Consider the weight of the laptop computer before purchasing. Laptops come in different sizes and some weigh a lot more than others. If you travel frequently or have the need to carry your laptop with you all day, consider a lighter weight laptop computer. Beware though, that while the laptop may be lighter, some of the components such as the AC adapter may not be included on the spec listing. Also, some of the ultra-light laptops do have smaller keyboards and screens, some only measuring 12 inches. Any laptop computer with a screen more than 15 inches can be difficult to carry. Consider the weight of the laptop when it is placed in a carrying bag, too. This will also add to the bulkiness of traveling with your laptop.
Other considerations to make when purchasing your new laptop are added features such as WiFi access, brand name and warranty. Most laptops come with a one-year warranty. An added warranty may be a good idea to protect your purchase.

If you are the owner of a laptop computer, you know how frustrating it can be when you are working on the laptop and your battery is low. If you are constantly on the go, it is sometimes difficult to find a place to plug in your computer to let it recharge. There are a few things that you can do to help you take care and extend the life of your laptop battery.
General caution should be observed when running the battery of your laptop. A laptop should be plugged in to the AC adaptor whenever possible. This will ensure that your laptop battery is always charged and ready to go when it is needed. Another tip is to not expose your laptop to extreme weather conditions, especially very cold temperatures. A cold battery will run much slower than one that is warm. Also, try not to use your laptop for long periods of time without recharging the battery. This can cause information to be lost if the battery sudden stops working.
When using your battery on your laptop, remember use as little power as you can by adjusting the settings on the laptop. This will make your computer go inactive when not in use for a certain amount of time. Adjusting the power setting is easy if you go into the control panel and set the display time. It is also possible to adjust the brightness of the screen display to help the life of the laptop battery. Remember to turn programs off that you are not using. This will waste battery usage quicker. Also, running movies and videos will quickly drain the battery charge.
When using your laptop battery you will want to make sure you check the battery charge frequently. Charge your laptop as soon as you see the battery getting low. Whenever you can, plug in your computer. It is a good idea to always plug in your computer so that it is ready to go. Also, take care of your battery. It is important to clean the laptop battery and keep it free of dust and debris. Using canned air or a cotton swab on a regular basis can do this. The battery will run longer if it is cleaned frequently.
Another tip is to have an extra battery on hand. These are easily purchased. Have at least one fully charged at all times for a quick battery change. Some laptops can run with two batteries. Most laptops are also compatible with external batteries that can easily be added and changed when necessary. Battery charges that work in the car are also good options for anyone taking their laptops on trips. Also, if you are purchasing a new laptop computer, consider buying a smaller, lightweight version. These are more efficient and are able to run longer on a battery charge than the larger laptop versions. Following these basic tips can help extend the amount of time your computer can run with a battery.
