But let also discuss the sub-notebook. Sub-notebooks are also called kneetops or ultraportables. They are called as such because of their small size compared to a standard-sized notebook. The savings in weight and size is due to the omission of ports and removable media drives. Although typically consists of smaller screen and keyboard, it is still equivalent with the standard-sized ones.
Below are aspects to be considered before buying notebook computers.
CPU (Processors). Notebook processors were always considered to be slower than desktop CPUs, but that has changed recently. Manufacturers are coming up with Dual-core processors which help with multitasking.
Notebook processors have limited amount of power as they have to run even when the notebook system is not plugged into an outlet. The less power that the notebook uses, the longer the system should be able to run for off the battery. Processor manufacturers thus employ a CPU scaling where a processor scales its power usage (and thus performance). However, this presents a major challenge in balanced performance and power consumption.
Memory (RAM). Compared to desktops, notebooks are generally more restricted in the amount of memory. Buyers must check the maximum memory can handle as well as the amount that is installed in the computer. Buyers must also ask manufacturers or suppliers if a memory upgrade can be done yourself or by a technician. The minimum amount of memory should at least be 512MB and for improved performance, at least 1GB.
Displays and Video. Video and display on a notebook computer is comprised of the video processor, screen size and the native resolution. Large displays have higher the resolution, but this will impact the portability of the system. Becoming more popular now are the wide screens. 3D graphics and PC gaming meanwhile are determined by the performance of the graphics processor.
Size and Weight. This aspect of the notebook is obviously important. Although ultraportables offer light weight and sizes, it sacrifices items such as drives. Desktop replacements oh the other hand have equivalent power to desktop systems. However, they are heavy and bulky making them difficult to carry around. Make sure to pick up the systems. This way, buyers could decide if its something they are willing to carry. Buyers must also consider the weight of accessories such as AC adapter when carrying around the notebook.
Drives. How much storage space will be needed? Hard drives are fairly straight forward in terms of the size. Performance may even be impacted by the rotational speed. When purchasing a notebook PC, optical drives play a more important role. It is best to at least get a drive that is capable or reading DVDs and burning CDs or DVDs. The reason? It is better to download software this way.
Networking. Most notebook buyers today buy them for the sole reason of web connection. Hence, ability to connect to the net is integral. Systems that include a built in 56Kbps modem and Fast Ethernet are best recommended. Most notebooks today also offer wireless networking as rise in this technology is seen. A notebook with 802.11b/g for minimum amount of wireless connectivity is best for beginners. It will give first-time buyers the most amount of connectivity.
Battery Life. A portable computer with only 30 minutes computing time to offer at a single charge is no good. Look for the manufacturer’s listed battery life for the standard battery. A system with at least 2 hours of battery life under normal conditions is best recommended. For extended time unplugged, laptops with media bays that can double as extra battery slots or have extended life batteries can be purchased.
