Computer Deal of the Week

Computer Deal of the Week

With the Thanksgiving holiday and the following Black Friday retailer specials coming, retailers are a bit more reluctant to make huge savings and specials. That made selecting a deal quite difficult for this week. There was also the issue that most of the advertised deals this week are only valid till Wednesday. Because of this, I instead am featuring a clearance offer.
NewEgg is offering a great deal on a the Sony VAIO VGN-C250N/B notebook for only $1100. This system kind of falls between an ultraportable and thin and light notebook. The 13.3" screen keeps it quite small and portable, but it still weighs 5 pounds that put it well above he weight of an ultraportable. It is powered by an Intel Core 2 Duo T5500 processor with 2GB of memory, 160GB hard drive and DVD burner. Unlike most notebooks though, it uses the Vista Business operating system. This makes it a great notebook for a business person looking for a highly compact but powerful system.

MY COMPUTER

MY COMPUTER

Your Computer’s CaseYour computer's case plays a large part in the overall expandability, protection, cooling and lifetime of your system.
ExpandabilityAt one time or another you may decide to add something to your computer. Maybe a CD Player, Zip Drive, a second Hard Drive, Floppy or Tape Drive. These fit on shelves in your computer called Bays. If there are no extra bays, then there’s no place for these devices to go. These bays can be 3.5 inches or 5.25 inches wide. There are internal and external bays. You can notice the external bays by looking at the front of your case.
Devices like floppy drives and CD-ROMs slide into external bays and can be seen (and accessed) from the front of your system case. If you have unused bays, they will have a plastic faceplate over them (or at least they should have). If you see that you have empty external bays, then you know that at least there's room to add another of this type of device. Remember however, that hard drives are sometimes hidden behind these faceplates, so a look inside the case will tell you for sure. Hard drives are generally situated in internal bays because there is no need for physical outside access. You must look inside the case to see if you have any free internal expansion bays.
Any device added to your system requires power, and your power supply has to have enough juice to supply that power. If you have a 150 or 200-watt power supply, your system may be limited to the amount of devices that can be added. Most cases come with a power supply, but make sure.
Getting Your Hands in ThereYou may at one time or another, have to remove, change or check a device in your computer. You want to be able to access that device without too much difficulty. It would be nice if you didn't have to remove the ribbon cables and expansion cards just to install another DIMM, or replace a battery. Or, if you're the type that likes to just jam his hand in amongst all that stuff, it would be nice to be able to remove it without accidentally loosening or removing other connections.
On some cases you can loosen a single screw, and completely remove the drive bays for easy access to the drives and their mounting screws. Others have access ports for the screws on the back plate of the case. However, I’ve seen some drive bays that are spot-welded in place without access ports, and you just about have to remove the motherboard to access the screws for the drives. Think about what you want to put inside and make sure there's enough room for access.
ProtectionA good, rigid, well built case can protect the internal components from dust, vibration, foreign objects, ESD and EMI. Electromagnetic interference is not always an easy one to nail down. My computer has a good solid case, but when you watch TV, you can tell if the computer is on or not.
You can find cheap cases that fit together so poorly, or are so flimsy, that they actually rattle when the computer is turned on. One thing that can be bad for your system are vibrations caused by outside sources; whether it’s a panel or cover that rattles, a desk drawer being closed, or a printer that doesn’t operate the smoothest. The stability of the case makes a big difference.
Some of the case frames are left unfinished, resulting in sharp edges, burrs and metal slivers. Ribbon cables and wires (and your fingers) can be nicked or cut by these sharp edges just by removing or replacing the outside cover. Companies that actually put some research and development into their product will address these issues. You should think about them when you purchase. As with just about everything, you usually get what you pay for.
LongevityHeat shortens the life of electronic components. The different devices and components inside your case need room to breathe and release heat build-up. Sometimes, things are packed so tightly inside your system case that you can’t even get your hand in to remove a cable or an expansion card, let alone allow for any kind of air flow. Air flow is needed to cool down the components and devices inside the case.
The cooler that your computer operates, the longer it will last. The fan on the power supply is made to help cool the power supply as it operates. The way the case is built should allow the intake of cooler air through vents, draw it over the different components inside to help cool them, and push the heated air out. Some cases come with auxiliary fans that fit over the intake vents to add to the airflow inside.
It’s important not to interrupt this flow. Don’t pack things around the case or obstruct the intake vents. Keep the intake vents clean and clear of grime and dust balls. Also, by leaving the expansion slot inserts off the back of the case, or the faceplate off unused external bays, you could possibly be changing the way the air flows through your case and reducing cooling efficiency.
If you have a system that seems to run fine, then just shuts itself off after a half hour or so, check out the operating temperature of the CPU. See that the fans are working on the power supply and the CPU's heatsink.
