Laptop systems have grown in popularity due to their
increasing performance and portability. For many people, they offer more than
enough performance and features that they have completely replaced the need for
a desktop computer. This guide will help you to look at some of the key items
you want to look at before you purchase your next PC laptop system.
Size and Weight
Obviously the size and weight of a laptop is important.
Ultrathin laptops such as Ultrabooks may be extremely portable but often lack a
few features. Desktop replacements have equivalent power to desktop systems but
they are heavy and bulky making them difficult to carry around. When shopping
for a laptop, make sure to pick up the systems and verify its something you are
willing to carry. Don't forget to also consider the weight of accessories such
as AC adapter when carrying around the laptop.
Processors (CPU)
Mobile processors typically were slower than desktop CPUs
but that has changed. Dual-core processors are typical now with quad core
models available for those looking for better multitasking. The type of
processors found in the laptop will vary based upon the size and purpose of the
laptop. They have a direct impact on performance as well as battery life so
comparison can be difficult. Check out my listings for suggested processors for
the various types of laptop PCs available.
Memory (RAM)
Laptops are generally more restricted in the amount of
memory they can have compared to desktops. When looking at computers you want
to make sure to check out the maximum memory the system can handle as well as
the amount that is installed in the computer. It is also useful to find out if
a memory upgrade can be done yourself or if it has to be done by a technician.
Four gigabytes should really be the minimum amount of memory to consider with
8GB for improved performance.
Displays and Video
The video on a laptop computer is comprised of the display
and the video processor. The display is defined by the screen size and the
native resolution. The larger the display, the higher the resolution will
typically be but it also will impact how portable the system is. The graphics
processor will determine the performance of the computer in things such as 3D
gaming or for accelerating non 3D applications.
Data Storage
How much storage space will you need? Hard drives are fairly
straight forward in terms of the size and the performance may be impacted by
the rotational speed. More and more laptops are opting to use the faster and
more durable solid state drives even if they offer less overall capacity.
Optical drives are becoming less important for laptop computers but many still
come with a DVD burner. Blu-ray is available for viewing high definition video
but are still fairly uncommon.
Networking
The ability to connect to the net is integral to most
laptops today. Pretty much every laptop comes with some form of Wi-Fi built in
with the 802.11b/g/n being the most common. Wired networking is still available
on most with Gigabit Ethernet being the most typical speed supported. Bluetooth
is useful for wireless peripherals and for those that need connectivity in
remote locations, a built-in modem or a cellular (WWAN) card are also options.
Battery Life
How good is a portable computer going to be if you are only
able to get 30 minutes of computing time on a single charge? Some systems may
advertise all day computing which really translates into eight hours which is
the typical length of a working day but most are much lower. Try to find the
manufacturer's listed battery life for the standard battery. Look to get a
system with at least three to four hours of battery life under normal
conditions. If you need extended time unplugged, look for laptops with media
bays that can double as extra battery slots or have extended life batteries
that can be purchased.
Warranty Plans
Laptops take a lot of abuse and are more prone to breakdowns
due to their portability. When buying a system, make sure to get at least a one
year warranty from the manufacturer. If you will be using the system heavily, a
system that comes with a two or three year warranty might be a better choice
but it will cost more. Third party extended plans are not a good choice unless
service is done through the manufacturer.
