The original wireless local area network (WLAN) standard was simply dubbed 802.11. It was standardized by the Institute of Electrical and Electronics Engineers (IEEE) in 1997, but was limited to 2 Mbps of bandwidth and averaged much slower. Its adoption was very limited, and few devices were created for the standard.

802.11b was the expanded standard that was specified in 1999. It could support bandwidth up to 11 Mbps, and became the first Wi-Fi standard to be adopted by a large number of consumers. In fact, most consumers’ first router was probably an 802.11b router. In addition to having more speed than the original standard, it also had better signal range, making it feasible to run a network throughout an entire house without significant signal loss.

802.11a is a lesser-known and less popular standard created around the same time as 802.11b. It was more susceptible to interference and signal loss, and was not implemented into most consumer products.

802.11g is currently the most popular Wi-Fi standard on the market today. Most WLAN devices support it, both in consumer products and business products, and it is the most widely supported by computers, phones, and other wireless devices. It supports bandwidth up to 54 Mbps, and its 2.4 Ghz frequency range promotes less signal loss and a longer range than previous standards.

Expanding on the success of 802.11b, the new 802.11n standard is the fastest yet, supporting bandwidth up to 100 Mbps and an even longer signal range, which is also more resistant to signal loss and interference. Having only recently been standardized, it does not yet have the popularity of 802.11g, and its higher price makes it a less-tempting upgrade for those already happy with their current setup. There is little doubt, however, that it is the future of Wi-Fi for at least the next few years.

Asus U50F-RBBAG05

Despite its long name, the Asus U50F is a great choice for buyers who want a full-size 15.6 inch screen and solid power and performance for a very low price. It has an Intel Core i3 processor, 4 GB of memory, and a 500 GB hard drive, giving it enough speed and storage to handle almost any need, and its only downside is relatively short battery life.

Asus Eee PC 1001P

The Eee PC’s ultra-low price might make buyers suspicious that its performance will be disappointing, but in fact, it is a very capable netbook that sacrifices very little to achieve its small form factor and affordable price. Not all buyers will like the small 10.1 inch display, but those who value portability will appreciate the compact and lightweight design, as it weighs only 2.8 pounds. The 160 GB hard drive might be a limitation for some buyers.

Toshiba Satellite T235D-S1345

Combining some of the portability of a netbook with a larger 13 inch screen, the Satellite T235D strikes a good balance by providing a little more power and performance. Its low price will be very appealing to budget-conscious buyers, but lack of an optical drive could be a major concern for some users.

Dell Inspiron 14R

The Inspiron 14R might be the most well-rounded in this lineup, as it not only features a Dual Core P6000 processor, 2 GB of RAM, and a 250 GB hard drive, but it also includes a dedicated ATI graphics card for gaming. The result is a machine that can handle a broad spectrum of tasks all at a very low price.

Gateway NV7915u

As the most expensive in this lineup, the NV7915u might be too pricey for many budget buyers, but it is mentioned for those who want a lot of bang for their buck. With an Intel i3 processor, 5 GB of RAM, and a 500 GB hard drive, it gives solid performance no matter what the task. It also includes some nice extras such as an HDMI port and multitouch track pad for convenience.

The many models and configurations of laptops available on the market mean that any user can find one to suit their needs. Budget-conscious buyers no longer have to sacrifice performance or features to get the price they want, and these laptops prove it.

Sony is one of the few laptop manufacturers to make their own laptop batteries. In fact, they also make laptop batteries for many other manufacturers. The majority of the batteries they make use lithium-ion technology. Lithium-ion is chosen for its long battery life, its large power-to-weight ratio, and lack of the “memory effect” that affects older battery technologies.

When shopping for a replacement for a Sony laptop battery, you should carefully remove the old battery to look for a model number or serial number that will help identify the replacement. First, shut down the laptop and disconnect its power cord. Turn the laptop over and find the release slider or button that releases the Sony laptop battery, then carefully remove it.

The easiest way to find a replacement for your Sony laptop battery is to use a parts locator tool, or a part number search, available at many online retailers.

It is a good idea to compare the voltage and amperage from your old battery to ensure they match the new battery you are planning to buy. In some cases, you may have the option to buy a battery with more capacity and longer battery life than the one you are replacing. Most of these batteries accomplish this by including more cells. For example, the original battery may have 6 cells, while the replacement battery has 9 cells, and therefore, longer battery life.

Replacing the battery in your Dell laptop is very easy. First, shut down the laptop and disconnect the AC adapter to ensure that no power is running to the machine. Second, release the latch near the current battery, and remove the battery. Align the new battery in the same way the old battery was removed, and snap it into place. You may need to fully charge the battery before running the laptop from battery power only.

Once all screws have been removed, the laptop’s hard drive should be able to slide out. The hard drive bay is marked with an engraved symbol, and is attached to the HP laptop motherboard. The next step to replacing Toshiba laptop motherboards, is to turn the computer back over, and open the screen’s lid. With a flat-head screwdriver, pry underneath the large plastic section, located above the keyboard. It is the housing for the indicator lights and power button. After removing the plastic housing, disconnect the cable connecting it to the HP laptop motherboard. Also remove the keyboard from the case, and disconnect the ribbon cable. Unscrew the screen hinges from the case, pull them out, and set them aside.

Locate the network card, and disconnect it from the port on the Toshiba laptop motherboard. Remove the screws holding the graphics card. Disconnect the card from the motherboard and set it aside. Then, remove the screws for the fan and heat sink unit on the laptop’s processor. Remove the unit and processor from the HP laptop motherboard, and with a screwdriver, take out the screws along its edges. Finally, lift the damaged motherboard out of the casing, and place it aside. Insert the one of the compatible motherboards for HP laptops into the casing, and reassemble the internal parts that were previously removed. It is highly recommended to take a photograph of the Toshiba laptop motherboard’s unit throughout the repair procedure, to utilize during the rebuilding process.

The first step in laptop LCD screen replacement is to being separating the screen bezel, from the display cover. There are no screws securing the bezel in place, therefore it should be easily removed from the hinges.
