Takeaway:  Tips for making environmental choices whether buying a new computer or maintaining your current one.

To reduce energy intake you can use a power strip, monitor usage with utilities and unplug components when not in use.  Deciding to go green for current computers or buying a new computer can help with power management to cut down on wasted energy and costs.

Energy Star is a voluntary energy efficiency program that prevents greenhouse gas emissions with strict guidelines.  EPEAT is an assessment tool to help users compare and purchase computer equipment.  Both provide tools to help make an environmental choice.

Buying a New Computer Tips:

• Research:  Find out if it is Energy Star rated, how much energy the computer will use and power management options.
• Recommendations:  Check out product reviews from previous purchasers and from non-profit organizations that provide accurate feedback (Such as EPEAT and Energy Star)
• Purify New PC:  Read the Hazardous Material Use Policy on manufacturer’s site.
• Don’t be Greenwashed:  Research the company to make sure that their “Green Computer” is not a marketing campaign with few benefits towards the environment.
• Green Guide:  If you would like user ratings and reviews for products, several websites provide these options as well as advice for purchasing new equipment. 

Upgrading Current Machine Tips:

• General Health Check:  The three major components that play a role in energy are graphics card, microprocessor and monitor.
• Replace CRT Monitor:  CRT Monitors may contain Lead, Mercury, Barium and more toxins.  Replace your old monitor with a new LCD or LED Monitor to save energy and money. 
• Upgrading Memory:  Upgrading your RAM will increase the speed of your machine while lowering the power intake, which is a quick, inexpensive fix.
• Greener Battery:  Similar to CRT Monitors, older laptop batteries contain hazardous chemicals such as lead.  Companies are starting to manufacturer Green Batteries that have a longer life expectancy using earth-friendly features.
• Greener Power Supply:  The ability to scale the power required for particular actions with your power supply is an efficient way to save energy; while regular power supplies emit a steady rate of power at all times.

Takeaway:  Five simple ways to protect your information when using WiFi and Hotspots.

WiFi is exchanging data through a wireless local area network (WLAN) from electronic devices including smartphones, laptops and tablets.

Also, WiFi is available in public places such as Airports and Restaurants.  Identity Thieves, Hackers and Criminals take advantage of WiFi because it is convenient for users to access personal information.

1.  Avoid accessing your bank accounts & online stores:

When using public WiFi, it is best to avoid using your credit card or banking information.

2.  Double check the WiFi name:

Prior to connecting to a public network double check with an employee for their network name.  Identity thieves can create a false Hot-Spot, have users connect and then steal personal information.

3.  Turn-Off “Auto Connect”:

Stay in control of what networks you connect to, smartphones have a setting that automatically connects you to the closest open network.  Simply, turn this setting off to decide what networks to connect to.

4.  Never use the same Password:

An additional step you can take to keep online accounts safe is to use different passwords for each account.   Using the same password makes stealing your information easier for criminals.

5.  Check the Lock:

The extra layer of security is the locked padlock in the address bar of your browser or “https” which means that your information has been encrypted.

For those infatuated with the 11-inch MacBook Air’s svelte form factor but still tethered to Windows, I’ve got two nice alternatives that are worth considering: The Sony Vaio X1 and the Acer Timeline X. I’ve put together a gallery of unboxing and product photos of both machines, along with some comparison shots next to the 11-inch MacBook Air.

While the Sony Vaio X1 and the Acer Timeline X are both worthy competitors to the 11-inch MacBook Air, they are two very different machines that will appeal to different sets of users. Here’s my quick take on the two of them.

Sony Vaio X1

Sony is known for its stylish PC hardware, but it often comes at a premium price tag — similar to Apple. However, in this case, the 11-inch MacBook Air and the Sony Vaio X1 have similar price tags to the Acer Timeline X. All three systems have a base price of roughly $1000. At that price, the three of them have remarkably different hardware profiles.

The Sony Vaio is the lightest of the three machines, and it’s also the most lightly powered. It runs a 2.0GHz Intel Atom processor, the same one that powers many netbooks (compared to the speedier 1.4GHz Core 2 Duo that powers the 11-inch MacBook Air). Here are some of the additional specs of the model we tested (VPCX131KX/B):

•2GB of RAM
•11.1-inch display with LED backlight and 1366×768 resolution
•Integrated Intel graphics
•64GB of flash storage
•2 USB ports, VGA port, Ethernet port, SD card slot
•3 hours of battery life (standard battery) or 12 hours battery life (expanded battery)
•Weighs 1.6 pounds (with standard battery)

The Vaio X1 is even a little smaller than the 11-inch MacBook Air. A business professional could easily slip it into a padfolio. Its portability and weight (or lack thereof) are its greatest assets, and it’s a solid machine for email, Web, and basic business apps. The tradeoffs are that it’s not a very fast or powerful machine and it feels a little overpriced for what you get.

My other concern with this machine is durability. Unlike the MacBook Air, which is made almost entirely of aluminum, the Sony Vaio X1 is totally plastic and not an especially durable blend. That makes it light, but also makes it feel very flimsy. I had the sense that I could have almost broken it in half with my bare hands if I twisted it hard enough.

Still, if you’re not too concerned about performance and you need a super-portable system, then the Vaio X1 is pretty impressive and worth a look.

Acer Timeline X

The Acer Timeline X can’t match Sony or Apple for style or thinness, but it packs a lot more power under the hood. The model we tested (1830T-68U118) was running an Intel Core i7 processor (1.46GHz) and offered very zippy performance for just about any task. The rest of the specs for the Timeline X included:

•4GB of RAM
•11.6-inch display with LED backlight and 1366×768 resolution
•Integrated Intel graphics
•500 GB hard disk storage
•3 USB ports, VGA port, HDMI port, Ethernet port, SD card slot
•8 hours of battery life

The Timeline X can keep up with a lot of desktop machines. It’s that fast. This is the system for someone who needs to pack a lot of performance but wants to do it in as small a package as possible. The Timeline X is certainly a little more heavy and bulky than the MacBook Air of the Vaio X1, but it is far smaller than most of the other laptops in its power class.

My beefs with the Timeline X are mostly qualitative. The touchpad is just too small to be very useful. The 11-inch MacBook Air is literally about three times the size of the Timeline X — and although I’m not a fan of touchpads in general, the one on the Air is one of the few that are useful in a pinch. With the Timeline X, make sure you have a good notebook mouse and plan to use it most of the time. On a related note, the keyboard on the Timeline X is not great either. The keys are huge but they are very close together, which makes it easy to hit the wrong key. The keys are also stiff and shallow, which isn’t very friendly for typing. This is one of the main areas where the Timeline X doesn’t match up very well with the MacBook Air, and to a lesser extent, the Sony Vaio X1.

However, if you want a lot of power in a small package and you want it to run Windows, the Timeline X is one of your best bets.

Many people don’t think about the hidden danger of heat to their computers, or how easy computer overheating is to prevent.

A lot of people don’t think about the effects of heat on their personal computer or laptop. The effects of overheating may be subtle, such as causing the computer to run slower or shortening the expected lifespan of the components; or it can be so devastating as to cause a fire. The most common side effect of overheating is having programs freeze or the computer shutting down sporadically.

How Computers Handle Heat
Computer heat is most efficiently handled by fans. The main fan is usually in the back and blows out. In addition there’s usually a heat sink — cooled by another fan or by a coolant system — over the CPU to prevent the processor from overheating. Some computers have additional fans to encourage airflow and help cool off high-heat components, but this varies from computer to computer.

The power supply can cause overheating if it is not properly installed in the case; if the vents aren’t positioned correctly the hot air can end up in the wrong place. The amount of free space inside the computer also matters; if all the hot components are close together, or if the placements of cords/components is impeding airflow, it can cause more heat problems.

What Can Cause Computer Overheating

There are several things that can cause a computer to overheat.

•Dust inside the computer and around the fans acts as an insulator, causing overheating.
•Running the computer in a hot environment also causes overheating.
•Running a lot of unnecessary programs can aid overheating.
•If the fans are obstructed by walls or drapes it can impede airflow.
•If the computer is being overclocked it can cause the components to overheat.
•Leaving the computer on for extended periods of time can cause overheating.
•Having the computer next to a hot device (a hot vent, other machinery, etc) can heat the computer.

How to Prevent Computer Overheating
By looking at the causes of overheating it’s often easy to diagnose and fix the problem that causes it. It’s important to resist the temptation to leave the computer open while running; the typical computer case is designed to conduct airflow, and leaving the computer open may make the overheating worse.
Simple Ways to Increase the Life of Any Computer’s Parts

The easiest way to prevent the computer from overheating is to clean it out. Most retail stores carry compressed air in their computer aisles, and it’s the easiest way to clean dust out of a dirty computer. A vacuum cleaner can also be used to suck the dust out of fans and ports along the outside of the computer.

Keeping the computer off the floor can help keep excess dust and dirt from mucking up the inside of the computer and fans. Also, putting additional fans in the computer can help improve ventilation. Many cases have specific spots for installing these extra fans; make sure that they blow the hot air out.
Don’t keep the computer too close to the wall, or near anything that keeps the hot air around the case rather than dissipating. It’s also helpful to make sure that the computer is free of debris — keeping stuff on top of the computer can insulate the computer as well.

When Nothing Else Works
When nothing else seems to be fixing the problem it may be hardware related: a broken fan or heat sink can cause major heating issues. If there’s a warranty in effect, contacting the manufacturer about any heat problems may be the easiest solution.

An overheated computer can cause any multitude of trouble. Knowing what can cause the overheating is most of the battle, and even the most novice computer user can get inside to clean the parts and check for broken fans.

CHICAGO — Have you ever worked on your laptop computer with it sitting on your lap, heating up your legs? If so, you might want to rethink that habit.

Doing it a lot can lead to “toasted skin syndrome,” an unusual-looking mottled skin condition caused by long-term heat exposure, according to medical reports.

In one recent case, a 12-year-old boy developed a sponge-patterned skin discoloration on his left thigh after playing computer games a few hours every day for several months.

“He recognized that the laptop got hot on the left side; however, regardless of that, he did not change its position,” Swiss researchers reported in an article published Monday in the journal Pediatrics.

Another case involved a Virginia law student who sought treatment for the mottled discoloration on her leg.

Dr. Kimberley Salkey, who treated the young woman, was stumped until she learned the student spent about six hours a day working with her computer propped on her lap. The temperature underneath registered 125 degrees.

That case, from 2007, is one of 10 laptop-related cases reported in medical journals in the past six years.

The condition also can be caused by overuse of heating pads and other heat sources that usually aren’t hot enough to cause burns. It’s generally harmless but can cause permanent skin darkening. In very rare cases, it can cause damage leading to skin cancers, said the Swiss researchers, Drs. Andreas Arnold and Peter Itin from University Hospital Basel. They do not cite any skin cancer cases linked to laptop use, but suggest, to be safe, placing a carrying case or other heat shield under the laptop if you have to hold it in your lap.

Salkey, an assistant dermatology professor at Eastern Virginia Medical School, said that under the microscope, the affected skin resembles skin damaged by long-term sun exposure.

Major manufacturers including Apple, Hewlett Packard and Dell warn in user manuals against placing laptops on laps or exposed skin for extended periods of time because of the risk for burns.

A medical report several years ago found that men who used laptops on their laps had elevated scrotum temperatures. If prolonged, that kind of heat can decrease sperm production, which can potentially lead to infertility. Whether laptop use itself can cause that kind of harm hasn’t been confirmed.

In the past, “toasted skin syndrome” has occurred in workers whose jobs require being close to a heat source, including bakers and glass blowers, and, before central heating, in people who huddled near potbellied stoves to stay warm.

Dr. Anthony J. Mancini, dermatology chief at Children’s Memorial Hospital in Chicago, said he’d treated a boy who developed the condition from using a heating pad “hours at a time” to soothe a thigh injured in soccer. Mancini said he’d also seen a case caused by a hot water bottle.

He noted that chronic, prolonged skin inflammation can potentially increase chances for squamous cell skin cancer, which is more aggressive than the most common skin cancer. But Mancini said it’s unlikely computer use would lead to cancer since it’s so easy to avoid prolonged close skin contact with laptops.
