Notebook and Laptop Common Questions and Answers
What notebook should I get?
What notebook you should get depends on the type of use that you anticipate.
Will the notebook be used only on a desk, and rarely be moved? If so, then a heavier “Desktop replacement” notebook might be ok for you. These models tend to be larger, heavier, consume more power and run for a shorter time on batteries. Battery life may be insufficient to watch a complete DVD. These might range from 6-10lbs. These notebooks often have desktop processors in them, either because they are less expensive, or because the fastest, most powerful processor is a desktop one. (ex. fastest P4 processor, vs. low end desktop P4) This type of notebook tends to run hotter than a portable notebook. This may result in more cooling fan noise.
Will the notebook be carried as luggage regularly? If so, a more portable notebook may be in order.
I can attest to a 5lb notebook starting to feel heavy after a couple of hours at an airport, or on the subway home after work. A Pentium M processor or other “mobile processor” would fit in to this class. “Centrino” notebooks also fall in to this class. (see Centrino FAQ)
Portable notebook processors are designed to run on lower voltages, run cooler, and have longer battery life. Watching two DVDs may be possible, depending on model/manufacturer and battery capacity.
What are common notebook brand names?
All of the major “computer” brands offer notebooks. Apple, IBM(
IBM thinkpad t42 Battery
), Dell, HP, Compaq, Gateway, Sony, eMachines, etc. A few, like Toshiba and Fujitsu, are known more for their notebooks than desktops. There are also “boutique” manufacturers such as Voodoo PC and Alienware who offer some very powerful machines. But you usually pay for the power.
One up and coming name is Sager, which seems to have a very loyal following. There are also lesser known brands that offer good machines at a decent price.
Some of the premium brands may appear to cost more, but include much better warranties and service (not to mention reputation) than the discount brands. That doesn’t mean one is better than the other. Quite the contrary: many discount brands offer a tremendous features to price ratio and have excellent reputations in service and support.
However, it does pay to research exactly what is offered in terms of features, price, warranty and after-sales service when considering a particular machine. Brand is not nearly as important as finding the best mix of features you want at a price you’re willing to pay, knowing that the company will help you for a reasonable amount of time if there is a problem.
What are common notebook LCD resolutions? Native resolution?
Conventional 4:3 resolutions typically include:
XGA (1024×768)
SXGA+ (1400×1050)
UXGA (1600×1200)
Some of the latest notebooks feature a 16:10 ratio wide-aspect display. The associated resolutions include:
WXGA (1280×800)
WXGA+ (1440×900)
WSXGA+ (1680×1050)
WUXGA (1920×1200)
XGA = Extended Graphics Array
SXGA = Super XGA
UXGA = Ultra XGA
“W” Prefix = Wide
WVA = Wide Viewing Angle
Native Resolutions and Image Scaling
Keep in mind that when purchasing a notebook, selecting the unit with the highest resolution may not always be the best choice. Flat panel monitors, commonly referred to as fixed matrix displays, operate best at their native resolution. An XGA LCD panel for instance, has 1,024 pixels in each horizontal line and 768 pixels in each vertical line. CRTs on the other hand, have a very large number of scalable pixels that allow it to display many different resolutions.
If a user purchases an extremely high
dell 1691p battery
resolution panel and decides to lower the resolution, the image quality is negatively impacted. For example, in order for an XGA panel to operate at 800×600 resolution, the image must be scaled up by 1.28x horizontally and vertically to fit the panel. Since 1.28 is not a whole-number increment, interpolated algorithms or “scaling” must be performed on the image. The image is stretched and distortion occurs. This scaling method results in somewhat blurry and fuzzy text.
The best way to select notebook LCD is to view it in person. Choose the highest resolution that you’re comfortable with.
For Windows operating systems, a “large fonts” option is available in the Advanced Display Properties. This will enlarge icons and fonts, making it more readable at high resolutions. To scale the entire user interface, a third-party software solution may be better. For instance, Portrait Displays offers a product called Liquid View which scales the user interface including toolbars.
Can I build my own laptop?
In short, no. Notebooks unfortunately can not be built in the same fashion as a desktop PC by purchasing all of the components and putting it together. At most, you can purchase a “whitebox” variety that is sold without cpu, memory, hard drive or operating system. However, you still can’t build your own notebook from the ground up like you can with a pc.
Do manufacturers build their own notebooks?
If you have just purchased a notebook from Dell(
Dell Inspiron Mini 10 Battery
), Compaq, Apple, or even eMachines, you might be surprised to know that they didn’t actually build your notebook. Most manufacturers, both large and small most often do not build their own notebooks. What they do is purchase them from ODM’s (Original Design Manufacturers) and customize the notebooks as their own. There are in fact only a handful of ODM’s who supply most of the major manufacturers with their barebone notebooks. Compal Electronics, Arima, Quanta Computer, and Inventec are a few of these ODM’s. Don’t be surprised to find that your Dell notebook looks very similar to another brand notebook. It is common to find very similar, if not identical, notebooks but with different manufacturer nameplates.
What about gaming on a laptop?
Gaming usually is more GPU bound than CPU bound, meaning, the GPU will make a bigger difference in gaming performance than the CPU.
Most lower end (or even the super-mobile) notebooks don’t have a dedicated GPU. Instead, they have intel integrated “extreme” graphics, which is DX7 level hardware. No pixel shading. This usually results in substandard gaming.
However, more and more midrange and Desktop-replacement notebooks are beginning to feature gaming GPU’s that have been modified (usually with clock gating) to lessen power consumption when the GPU isn’t being used for gaming.
Game-worthy mobile GPU’s:
Geforce 2 go (aging, but okay) DX7
Geforce 4 go DX8 (the 4×0 series is DX7)
Geforce fx 56xx go DX9
Geforce fx 5200 go DX9 (marginal performance)
Geforce fx 6800 go DX9
Mobility Radeon 7500 DX7 (also aging, but okay)
Mobility Radeon 9000 DX8.1
Mobility Radeon 9600 DX9
Mobility Radeon 9700 DX9
Mobility Radeon 9800 DX9
Mobility Radeon X800:
What is Centrino Technology?
Centrino Mobile Technology is a combination of 3 Intel components found in the same notebook. These components are:
1. Intel Pentium M based Processor
2. Intel 855 Chipset Family or the Mobile Intel 915 Express chipset.
3. Intel Pro/Wireless Connection
In order for a
sony vgp-bps9 battery
notebook to be labelled as having “Centrino Mobile Technology”, all three components must be available in the notebook. It is a common misconception that “Centrino” is a processor, but it is the combination of the three components listed above.
Centrino Duo Mobile Technology
This is simply an extension of the existing Centrino platform. A Centrino Duo system includes the Intel Core Duo or Core 2 Duo Mobile Processor, the newer 945 Express chipset, and the tri-mode Intel Pro/Wireless 3945ABG adapter.
What does DTR mean in reference to notebooks?
DTR is an abbreviation for Desktop Replacement. Generally this abbreviation is reserved for the larger, heavier and more powerful notebooks that can be used as a replacement for one’s desktop PC. These notebooks typically have large (15.4″) screens, a non-mobile processor (such as a pentium 4 processor), weigh above 6 pounds and have a low battery life (usually 2 hours or less). Not everyone purchases notebooks for portability. Some people prefer having less clutter and a DTR notebook will offer them exactly that.
Can I upgrade my notebook?
Yes. Almost all notebooks that are sold can be upgraded in one way or another. The most common upgrade would be to add more RAM or a larger/faster hardrive. Optical drives can also be upgraded in many notebooks. Some of the more expensive, enthusiast notebooks also have upgradeable video cards.
Many notebooks ship with 4200 rpm hard drives, these can be a bottleneck, slowing down any processes that rely on disc access.
Although it is possible to upgrade your notebooks CPU, it is not recommended. It will almost always void your notebooks warranty.
As with any upgrade, always check with the manufacturer before attempting to upgrade any components.
