11/21/2008 - What You Can Upgrade on Your Laptop

While laptops provide you with the ability to have the functionality of a desktop but in a more compact form there are other differences and one of the biggest is the ability to upgrade components in your laptop btp-43d1 , travelmate 220 , btp-58a1  . There aren't as many that can be upgraded because of the design - more is integrated into the motherboard compared to desktops. You can upgrade some components and knowing which can be upgraded at a later date may affect your decision to purchase a particular model  a1079 , a1078 . If you can save a bit of money now and later purchase upgrades as you need or can afford them.

11/21/2008 - DV Camcorders

Ever since home movie cameras were invented, people have been pointing them at one another and asking family and friends to do something amusing. And right from the start, people have been bored silly watching movies of others not doing anything amusing. Fortunately,  nb-4l , nb-3l , nb-5h , nb-5l   the latest digital video camcorders and video editing software make shooting and editing a movie as simple as using a word processor, so it's easy to cut out the boring stuff and just show the priceless part where Uncle Bob trips over the cat and falls into the swimming pool. For more details on video editing apps, see our March 2002 review "Must-See DV." For our look at DVD authoring programs, see the June 2002 story "Author Author."

Digital camcorders still use videotape (most use a format called MiniDV), but some can also store video on memory cards. np-fc10 , np-fc11 , np-fe1 Camcorders that store video exclusively on memory cards are now available, as well: Panasonic recently launched the SV-AV10, which can record up to 30 minutes of video to a Secure Digital memory card. However, this camera records video at a much lower resolution than a MiniDV camcorder does and highly compresses it, so memory cards won't start supplanting videotapes as the most convenient way to record video anytime soon.

PC World Spotlight on Digital Camcorders (chart)

Key Features
Screen: Having a large LCD screen on a camcorder lets you more easily see what you're recording and facilitates playback previews en-el1 , en-el3 , en-el5 , en-el9 . When shopping, try the screen in daylight if possible; some wash out in bright sunlight, one environment in which you'll often be using the camcorder. A viewfinder, meanwhile, is easier to see in daylight and uses less power, extending the camcorder's battery life.

Lens: Most modern camcorders have at least a 10X optical zoom, which should be adequate for general purposes. Vendors typically advertise the maximum digital zoom, but to achieve that length of zoom the camcorder enlarges part of the image to fill the screen, leading to grainy, pixelated, and generally unpleasant-looking images. At higher digital zoom settings,blm1 , li-10b , li-12b , li-40b   the quality is so poor you can't see what you are taping. Fortunately, most camcorders allow you to turn the digital zoom off or restrict how far it can zoom in. The spec for maximum optical zoom is the more interesting figure: It denotes the maximum zoom that the lens itself can achieve without enhancement.

Batteries: Most camcorders won't last more than an hour with the included batteries. So factor in the cost of a higher-capacity battery that can keep the camcorder going, if you think you'll need it. A higher-capacity battery that can double the casio  battery life typically costs $50 to $100.

Microphones: We've found that camcorders with microphones mounted in the front tend to produce better sound than those with microphones on the top; in particular, top-mounted microphones frequently pick up the voice of the person using the camera, bp-2l12 , bp-522 , bp-930 , bp-945 , bp-911 ,  drowning out everything else. Many of the more-expensive camcorders offer zoom microphones that can emphasize the subject's voice and minimize other sounds, and some also come with a socket to plug in an external microphone. Either type of microphone can be very useful when you're recording presentations or speeches and want to record the speaker but not the audience.

CCD size: As a general rule, the more pixels the camcorder CCD (the chip that captures the video) has, the better the image quality of the resulting video will be. Most camcorders also offer some form of image stabilization, in which the camera will try to compensate for vibrations that could result in blurred video.

Ability to take still images: Many digital camcorders can act as digital cameras, saving still images to a memory card. Some can save images at the same resolution as a 2-megapixel camera  bn-v12u , bn-v22u , bn-v25u , bn-v306 . However, none of the camcorders we've tested have worked as well as dedicated still cameras do; they don't provide the same level of control or the same image quality. Many vendors offer similar models with and without this feature; if you aren't likely to use it, you can save $100 or more by choosing the model that lacks it.

Controls: One important buying consideration is how well the camcorder balances size and usability. We have found that the controls on some smaller camcorders (such as the Sony DCR-IP5 and the Canon Elura 40MC) can be difficult to use because the controls don't naturally sit where your fingers fall; you sometimes have to shift the camera to reach them, or use both hands. In particular,  bn-v408 , bn-v416 , bn-v428 , bn-v507 , on many smaller camcorders the zoom control (a control that most people use a lot) can be awkwardly placed.

Low-light recording: Many camcorders can record in very low light, either with the help of an included infrared light (which you can't see, but the camcorder can) or through a special long shutter mode that makes the most of the existing light; some more expensive models offer both. These can be useful in poorly illuminated settings, such as when you're capturing a camping trip or the creatures entering your yard after nightfall. Low-light footage may be grainy, however, bn-vf707 , bn-vf714 , bn-vf733  and camcorders that use an infrared light capture only black-and-white video.

Format: Most camcorders use the MiniDV videotape format, but Sony also offers Digital 8 and MicroMV formats. A Digital 8 camcorder records digital video onto Hi-8 videotapes and can also play back analog videotapes recorded on Hi-8 camcorders. MicroMV camcorders (such as the Sony DCR-IP5) use a new type of tape that is smaller than MiniDV tapes. A MicroMV camcorder, sb-l110 , sb-l160 , sb-lsm160 , sb-lsm80 .however, compresses the digital video much more than a MiniDV camcorder, so most digital video editing programs are unable to edit the video. Sony does bundle a basic video editing program with its MicroMV camcorders, though; with most other camcorders you have to buy one separately. Many digital camcorders can record from a composite or S-Video source, as well, so you can transfer video from an older analog camcorder onto digital tape.

Recommendations
Many dissimilar digital camcorders are available, priced from $500 to $2000, so spending some time familiarizing yourself with the designs of various models before buying is worthwhile; the way a camcorder feels in your hands can be an important factor. Smaller camcorders (such as the np-f330 , np-f550 , np-f750  ) often cost more than larger ones, but you can carry them in a pocket. Though plenty of cheaper models exist, we recommend you spend a little extra on a camcorder that includes a wider range of features, such as the Panasonic PV-DV702, a unit that has a bright, large LCD screen; a zoom microphone; and both long-shutter-speed and infrared low-light recording modes  np-fm50 , np-fm70 , np-fp50 , np-fp70 , np-fp90 .

11/19/2008 - Acer: No major laptop battery improvement in offing

Dreams of fuel cells serving the power needs of a laptop PC or other new technology to significantly increase battery life won't likely be available for years, an Acer Inc. executive says.

In fact, the recent recall of nearly 9.6 million notebook PC batteries over fears a manufacturing problem could cause them to overheat or catch fire highlights the main reason why thinkpad r60  technology moves slower than other technologies inside a laptop, said Jim Wong, president of IT products at Acer Inc., in an interview on Thursday.

Safety is a huge issue with batteries. Electricity is generated by chemical reactions inside a battery, which produces heat as a byproduct. With so much chemistry involved, a lot more product testing is required, therefore thinkpad t60  technology progresses more slowly, he said.

"The lithium-ion materials used in batteries today were discovered 30 to 40 years ago," said Wong.

Fuel cells are promising, but the technology isn't ready yet, and an infrastructure needs to be in place before the technology can be widely used, he said.

Fuel cells require fuels such as hydrogen,  40y6797 , 40y6799 , butane, methanol, or natural gas to produce power. Not only would fuel packets or refueling stations be needed for mass adoption of the technology in laptops, they would also need to be approved by aviation officials for use on airplanes.

There has been progress made on such approval, but in an age of terrorism fears, where even cigarette lighters have been banned, a1012 , m8511  ,  a1078 , the process is moving understandably slow. And users aren't likely to buy a laptop that can't be taken with them on vacations or business trips that require air travel.

The battery issue is gaining more importance recently because the new era of multimedia laptops threatens to shorten battery life.

"High definition is a most formidable enemy to battery life," said Wong.

HD DVD and Blu-ray Disc players in laptop PCs really drag on battery life. Companies offset some of the drain by putting bigger a1079 battery inside machines and with power management technology aimed at shutting off parts of the machine that aren't immediately being used. But such improvements only help a little bit. They're not the kind of breakthrough that fuel-cells are expected to be.

Question: If I overcharge my thinkpad t43  laptop battery, will the life span decrease?

Answer:

First it¡¯s important to understand what overcharging is:
Over-charging occurs when the charger keeps the 08k8198 battery at a temperature that is warm to touch (body temperature) while in ready condition.

Li-Ion thinkpad r50  laptop batteries have built-in controller chips which prevent it from overcharging, as they can explode if overcharged. Overcharging does not affect the life span other than potentially destroying the battery.

A lithium-based thinkpad r51 series  battery should never be allowed to get warm in a charger. If you have this happen, the battery is no good or the charger is not working properly. Don¡¯t continue to use the battery or charger if this happens.

A Lithium-ion thinkpad r40 battery  may be damaged by extensive overcharging (continuously on a charger for more than 24 hours). Damage to the battery from overcharging would only occur in the very unlikely event of a malfunction of the charging system.

11/19/2008 - HP Extends Laptop Battery Life to 24 Hours

Hewlett-Packard (HP) will release a laptop next month that can run for to 24 hours using a high-capacity hp f4812a battery  -- but only if it's running Microsoft's Windows XP operating system.

The long-lasting notebook will be a special configuration of the 6930p, part of HP's EliteBook line that the company targets at businesses.

The allure of a battery that can last a day is incontestable, as anyone who has spent time in an airport searching for a power outlet knows. The secret to the 6930p's long battery life is new technology -- and some old technology too.

To get the best hp pavilion dv2000 battery  performance, the 6930p will have to run Windows XP rather than Windows Vista, Microsoft's latest operating system. Vista has been criticized as being a power hog, although some of its flashy, power-draining features such as the translucent Aero windows can be turned off.

Although Microsoft has been heavily pushing Vista, HP has said it will offer downgrades from Vista to Windows XP on business laptops through next year.

The 6930p will also need a 12-cell Ultra-Capacity hp f2299a battery  , which sells for US$189. The battery lasts about 10 hours longer than the regular-capacity one.

The new laptop model will also have HP's Illumi-Lite LED (light-emitting diode) display, which the company says adds four more hours to a battery's life than a traditional LCD (liquid crystal display) screen.

Further power savings will come from the use of an Intel SSD (solid-state drive), which uses power-saving NAND flash memory rather than a rotating magnetic disk to store information. Use of an Intel SSD enables the  hp pavilion dv4000 battery  to last around 7 percent longer, HP said.

HP is one of Intel's partners and will soon being incorporating Intel X25-M and X18M Mainstream SATA SSDs in its products.

HP lists the current available version of the 6930p as starting at $1,199 on its Web site, although the company has not listed how much the 24-hour hp pavilion zd7000 battery  life configuration will cost.

11/17/2008 - Clean Battery Posts = Reliable Starting

You should never let anything come between your car and a good dell latitude d520 battery connection. If you want the day to come to a grinding halt in a hurry, driving with corroded dell 6y270 battery posts is the way to do it. It takes only a millimeter of crunchy white residue to keep your car from starting.

Your car's battery is the starting point (no pun intended) for every system it uses. This is because it's used to start the car! The conditions surrounding your dell inspiron 2000 battery  posts create the perfect breeding ground for nasty corrosion, which will appear as white, crusty residue around the dell latitude cpi battery  posts. As the corrosion builds up, it becomes harder for your car to connect strongly with the dell inspiron 6000 battery . That's why we need to get rid of it.

There are scores of products out there to clean yourdell inspiron 600m battery and help keep it that way. Here you'll find a couple of them, but the idea is pretty much the same regardless of your method - get 'em clean.

11/17/2008 - Cleaning Your Battery Posts

The tried and true way to get yourdell inspiron 8200 battery posts and terminals clean involves a wire brush and a little elbow grease. You'll need a medium-stiffness wire brush. If you can bend the bristles back and forth easily, that's medium enough. You should also wear eye protection, and maybe even a dust mask. Brushing corrosion sometimes causes it to fly around.

With the terminals off thedell latitude d600 battery posts, liberally brush all of the parts, especially the inside of the terminals, until the corrosion is gone and you are looking at clean metal. A dell 8n544 battery  toothbrush-sized brush makes it easier to get to the inside part.

Once they're clean, install anti-corrosion discs if you're using them (see next step), re-install the terminals, positive side first, and you're good to go!

11/15/2008 - Battery Point Lighthouse

Near the Oregon border at Crescent City,hp pavilion dv1000 battery  Point Light was first lit in 1856, long before the Spanish had influence on the architectural design of the region. Since then, the structure has weathered many changes including automation in 1953 and a tidal wave that flooded the peninsula in 1964.

In the 1850s, lumber was being harvested in Northern California and sent south to build the rapidly growing city of San Francisco. Crescent City was a hub of lumber shipping,  and many ships loaded with precious lumber were in danger on the rocky coast hp pf723a battery , hp 367759-001 battery . The station's first official keeper was Theophilus Magruder, who arrived at hp pavilion dv4000 battery  Point on Christmas Day in 1856, thus the origin of the light's local name as "the Christmas light." Magruder was a sophisticated Easterner who was drawn to the west coast by the promise of gold.

Captain John Jeffrey and his wife Nellie took over the station in 1875 and stayed there for 39 years. The location was a trial for the Jeffreys family, and Captain John sometimes had to get out a boat and row the children to shore so they could attend school. The family's difficulties didn't end there, either. In 1879, a huge wave knocked down the kitchen wall, knocked over a lighted stove and the house would have burned down if it weren't for a second wave that put out the fire.

In 1964, the earthquake that stuck Alaska sent a tidal wave toward   hp presario m2000 battery and hp presario v2000 battery
  Point Light that threatened to finally destroy it, but the light and its keepers were spared because the wave struck at an extreme angle that protected the structure. Crescent City was not quite so lucky, though, as 29 city blocks were destroyed.

Accessible by foot only at low tide, Battery Point is currently a Maritime Museum and is operated by Del Norte County. The Cape Cod structure built of brick and granite offers visitors a look at the maritime history of the region and gives great insight to the life of a light Keeper. Worn from storms and tidal waves hp pavilion dv2000 battery , hp hstnn-lb31 battery  , this 45 foot tower and attached lean-to still function today as an important navigational aid to seaward travelers along the northern Pacific coast.

The light is reputed to house a resident ghost, seen by at least six different people, who have heard its sea-booted feet slowly climbing the tower steps during storms.

Visiting hp f4486b battery  Point Lighthouse
Access to the light does depend upon the tide, thus making it important to call ahead (707) 464-3089. To learn more about visiting the hp cgr-b1870ae battery Point Lighthouse, visit the Del Norte County website.

Battery Point is located in Crescent City, just a few miles south of the Oregon border. Go west from US 101 on Front Street, then left onto A Street.

11/15/2008 - Battery Fires & Explosions

Lithium laptop battery can provide an extremely high power output over a long time. This is great news for high-demand devices, like my digital camera, cell phone, and laptop. However, this also means the batteries discharge violently when short-circuited. One type of lithium dell inspiron 2500 battery  is the lithium ion polymer battery (Li-Poly or LiPo). These are rechargeable batteries. LiPo dell latitude cpx battery  , dell latitude c600 battery  can be made into almost any shape and they self-discharge less quickly than nickel cadmium and nickel metal hydride cells. Like other lithium batteries, they are pretty expensive, but the ability to be recharged helps offset the cost. If you use LiPo batteries you probably recharge them casually in your home, but you may want to consider the hazard recharging dell 312-0068 battery  may present. The Utah Flyers Organization has a video that documents some of the characteristics of lithium battery fires.

Impressive fires, huh? Ok, I know myself well enough to recognize I'll still charge dell 8n544 battery   and leave them unattended, but I'll be a bit more cognizant of the surroundings (like not charging them on a desk of papers). One other note: lithium reacts violently with water, so if you have an accident with a lithium dell inspiron 2000 battery , call your local fire department rather than trying to wipe up the mess with a damp paper towel.
