Q: How is a laptop different from a desktop? A: Laptops are portable, use less energy,
and make less noise than desktops. Other than that, they're
not much different. In a laptop, the screen (monitor) and
keyboard is integrated and the components are installed
in the laptop's design to fit snugly together. In
a desktop, the monitor and keyboard must be installed and
the components are more widely spaced.
Q: Laptop? Notebook? What's the difference? A: Laptop is the original term given
to mobile personal computers. While they were smaller than
desktop computers and could be set on your lap (thus the
moniker), they were still fairly sizable. Certain laptops
today come much smaller and lighter and are roughly the
size of an A4 sheet of paper, thus the term "notebook".
Other than that, they are one and the same.
Q: What screen
size should I look for? A: Laptops are portable, use less energy, Laptops
generally have 12-17" screens or wide screen displays.
Larger screens equal heavier laptops. Predictably, smaller
screens will generally mean smaller weights.
Q: How much memory is enough memory? A: About 256 MB of memory is good starting
ground, but 512 MB to 1 GB is much better for getting the
best performance out of your system. And always remember
that memory is upgradeable.
Q: What is a graphics controller? A: The graphics controller, or graphics
card, is the part of your laptop that handles everything
that shows up on your screen. Graphics controllers can be
integrated fully into your laptop's motherboard and
share video memory with your system's onboard RAM.
This means that if you have 512 MB of memory for you laptop
and your graphics controller shares 128 MB of the system
memory, at peak usage you would have 384 MB of memory free
for other programs. Other graphics controllers come with
there own onboard video memory separate from the laptop's
system memory. This means your graphics controller doesn't
need to pull from system memory.
Q: I want to use my laptop for gaming. What
kind of graphics card do I need? A: The integrated graphics card in
most laptops will provide the necessary graphics support
for e-mail, word processing, and browsing the Web. Mid-range
cards are usually sufficient for casual gamers. Hardcore
gamers and people who do 3-D work may want to look into
higher-end cards or dedicated graphics cards.
Q: I'm a student and I need a laptop
for school. What should I look for? A: Price is usually the biggest concern
for students. Obviously, you have to stay within your budget.
However, it is important to choose a laptop that will be
expandable later. If you get 256 MB of memory (about as
low as it goes these days) you should make sure that your
new laptop comes equipped with additional memory slots.
Also, check with your university- they usually make recommendations
as to what laptops are appropriate for your coursework.
Q: What kinds of laptop batteries
are there and how to they differ from one another? A: The first, Lithium Ion (Li-Ion),
is one of the newest cell types available. It's lighter
than any other battery type currently on the market and
provides more power than other main battery types. It's
easy to care for, but its high engineering cost also makes
it more expensive. Nickel Metal Hydride (Ni-MH) was the
most commonly battery found in laptop computers today, though
the Li-Ion battery has overtaken it in popularity. It is
cheaper than Li-Ion to manufacture and therefore cheaper
in price. Nickel Cadmium (Ni-Cd) is one of the oldest types
of batteries and is generally only found in older laptop
models.
Q: What is the average life of the
Li-Ion battery in my laptop? A: They may last an average of 2.5
to 3 hours for a 6-cell battery and 4 to 6 hours for a 9-cell.
Q: Should I purchase an extra battery? A: If you plan on traveling extensively
it is essential to pick up a spare battery. There is nothing
worse than needing access to your precious data, but running
out of battery at the worst time.
Q: What is FireWire? A: FireWire is a name for the IEEE
1394 interface. FireWire transfers data at higher speeds
than USB and allows you to transfer data quickly to FireWire
equipped products like digital cameras, printers, external
hard drives and iPods.
Q: What resolution should I look for? A: What you use your laptop for dictates
on what resolution you may need. If you spend most of your
time doing spread sheets and the like, having super resolution
is not a necessity. If you deal with lots of graphics and
digital imaging, having the larger resolutions give more
room to work with and usually come with the graphics controller
to push those images across your LCD screen. Generally speaking,
more pixels mean a crisper screen image, but it's
necessary to view the screen in different light settings.
A screen may look good in normal light, but unviewable in
bright or low light environments.
Q: What is XGA? A: XGA refers to screen resolution.
Laptops come with resolutions from XGA (1024 x 768) to SXGA
(1280 x 1024) to UXGA (1600 x 1200) for standard viewing
screens. A "W" in the title means widescreen
and gives you resolutions of WXGA (1280 x 800) to WSXGA
(1680 x 1050) to WUXGA (1920 x 1200).
Q: What is a modular bay? A: Some laptops come with what is known
as a modular bay. This is a swappable slot for optical drives,
extra hard drives, or extra batteries. This is a great option
to have for those that need all the functionality of a desktop
on the go.
Q: What is caching? A: Cache technology uses a smaller,
but faster memory type to accelerate a larger, but slower
memory type. Simply put, it helps to maximize the speed
of your laptop by performing tasks more efficiently.
Q: What is the difference between
L1 and L2 caches? A: L1 cache means the memory accesses
at full microprocessor speeds "about 10 nanoseconds" whereas L2 cache has a speed of about 20 to 30 nanoseconds.
Q: Should I purchase a case? A: A case is one more way to protect
your investment. Manufacturers offer cases designed specifically
for their products, while other companies produce cases
designed to fit a variety of brands. Don't worry -
you should be able to find a style that matches your outfit.
Q: Do I need an extended warranty? A: Laptops are sensitive, complicated
pieces of equipment and a lot can go wrong. A good warranty
covers you on parts and labor for three years, as well as
having toll free phone assistance. While most of the time
you won't encounter problems, it is better to be safe
than sorry. Super Warehouse offers warranty coverage that
extends beyond the basic manufacturer's warranty and
can be purchased for about 10% of the total cost.
Q: What other features should I
consider when choosing a laptop? A: Other good features to look for
when shopping for a laptop are USB and FireWire connections,
a DVD player, and anti-theft/security devices or software.
