Extend battery life

Strategies for conserving battery power
Have you ever run out of battery power on your mobile PC during a meeting or a class? Have you worried about running out of power while waiting to meet with a client? Have you asked yourself how much longer your battery will last? Sufficient battery life is a persistent challenge for mobile PC users. But Windows offers several ways to help maximize the battery life of your mobile computer.

In this article, I’ll discuss how to take advantage of Windows settings to manage power more efficiently. I’ll also introduce some non-software related tips that you can use to extend battery life.

Optimize your power settings
The display and hard disk on your mobile PC are the two biggest consumers of battery power. By choosing a power plan (called a power scheme in Windows XP) you can extend your battery life. A power plan is a collection of hardware and system settings that control how your mobile PC manages power.

Windows XP users

You can also create a custom power scheme to suit your specific needs. You can create as many custom power schemes as you want.

Take advantage of low-power states
The different versions of Windows provide the following battery-saving states:

Windows 7: sleep and hibernation (which is like deep sleep)

Windows Vista sleep and hybrid sleep (which is a combination of sleep and hibernation)

Windows XP standby (which is like snoozing) and hibernation (which is like deep sleep)

Sleep (Standby)

In a sleep state (standby), your display and hard disk turn off, and all open programs and files are saved in random access memory (RAM)—your computer’s temporary memory—rather than to the hard disk. Information stored in RAM is cleared when the computer turns off, so it’s a good idea to save your work before placing your system in standby mode. Otherwise, you may lose data if you lose power, you swap batteries, or your system crashes.

Sleep (standby) is particularly useful when you’re using your mobile PC intermittently during the day. For example, when driving between clients’ offices during the day, put your computer to sleep or on standby to maximize the life of your battery and maintain quick access to open programs, files, and documents. When you want to use your computer again, it wakes up quickly, and your desktop is restored exactly as you left it.

Hibernation

In hibernation, your computer saves everything to your hard disk and then shuts down. When you restart the computer, your desktop is restored exactly as you left it. Hibernation uses less power than the sleep state (standby), but it takes a bit longer to resume.

Windows XP

Hybrid Sleep

Hybrid sleep is a power-saving feature designed primarily for desktop computers. Hybrid sleep saves any open documents and programs to memory and to your hard disk drive, and then puts your computer into a low-power state.

Adjust screen brightness
You can also conserve battery by reducing the screen brightness. To adjust your screen brightness, refer to the instructions from your mobile PC manufacturer. Every computer is slightly different, but you can usually use a combination of keys, a function key, or a software tool to dim the screen.

Even better than dimming the screen is blanking it completely when you’re not using your computer. You can further minimize power consumption by reducing the amount of time the computer is idle before the screen goes blank.

Turn off wireless
Another significant drain on your battery power is your wireless card. You should turn off your wireless device when you’re using your mobile PC but are not connected to a wireless network. You can either remove your Wi-Fi card or press the manual hardware button on your computer if you’re using a Centrino-based mobile PC. Refer to the instructions from your mobile PC manufacturer to learn where the manual hardware button is.

Additional power saving tips
In addition to adjusting power settings to maximize battery life, consider the following tips to minimize power consumption when you’re away from electrical outlets.

Turn off scheduled tasks. If you use scheduled tasks to run programs or scripts, or if you schedule other tasks to occur automatically at a preset time, specify that these tasks won’t be performed when the computer is running on battery power.

Keep the use of tools in the notification bar to a minimum. Try to minimize your CPU’s usage. Look at the notification area of the taskbar and close any tools (or utilities) that are not necessary. Often, these tools are installed on the computer when you first receive it. Windows 7 users can also click the up arrow at the end of the notification area to see tools and utilities that are hidden but available. The notification bar, shown below, is on the bottom right of your computer desktop.

Limit power-intensive activities. Avoid watching a DVD or playing online games on your mobile PC when you need to conserve battery power.

Add memory. You can minimize the reliance of Windows on virtual memory and reduce power consumption by adding memory (RAM) to your mobile PC.

Carry at least one spare battery. Buying an extra battery is a good investment for your peace of mind. Battery prices vary widely. You can significantly increase the power available to you if you’re willing to splurge a little. Contact the manufacturer of your mobile PC to find a replacement battery.

Charge your battery often. When you’re on the road, be sure to carry a power cord and plug your computer in whenever you have the chance.

Completely drain nickel-based batteries. If you’re using an older laptop (at least 3 years old) with a nickel hydride battery, be sure to completely drain it and recharge it monthly to ensure that it will hold its charge. Most newer mobile PCs use lithium ion batteries, which don’t need to be drained to maximize their capacity.

By adjusting your mobile PC settings to conserve battery power and by implementing these tips, you can relieve the stress and inconvenience of running out of battery power.

5 ways to make your keyboard
easier to use
For most people, the keyboard is the main way to enter information into and control their computer. But are you controlling your keyboard, or is your keyboard controlling you?

If you make typing mistakes or find your keyboard a bit uncomfortable, it’s not hard to correct those problems. Here’s how to quickly and easily change your keyboard settings and comfort options.

1. Get to know your keyboard
Even if you’ve been using a PC for a long time, there may be features on your keyboard you don’t know about. Take a moment to get to know your keyboard so you can be more efficient when you’re working.

2. Change keyboard settings
Once you’ve gotten more familiar with your keyboard, there are a few settings you can change to help you work more smoothly.

You can alter:

How long you need to press a key before the keyboard character starts repeating.

The speed at which keyboard characters repeat, which helps you to avoid typing errors.

The rate at which the mouse pointer blinks, which can help its visibility.

Here’s how to change keyboard settings in Windows Vista or in Windows XP .

3. Take shortcuts
Even if you’re a whiz with the mouse for Windows 7, Windows Vista or Windows XP, keyboard shortcuts are typically a more efficient way to work. They’re called shortcuts because they reduce multiple clicks into one quick press of keys, like hitting a chord on a piano.

Getting to know a few keyboard shortcuts for the things you do all the time, like saving or closing files, can make using your PC much easier and faster.

Here are just a few popular keyboard shortcuts that work for both versions of Windows:

Press this
To do this
Windows logo key
Open the Start menu
ALT+TAB
Switch between open programs or windows
CTRL+S
Save the current file or document (works in most programs)
CTRL+C
Copy the selected item
CTRL+Z
Undo an action
Windows logo key +F1
Display Windows Help and Support
ESC
Cancel the current task
Application key
Open a menu of commands related to a selection in a program. Equivalent to right-clicking the selection.
For more, see the detailed list of keyboard shortcuts for Windows Vista, or Windows XP. Note: shortcuts for Windows 7 are the same as those listed for Windows Vista.

4. Make it easier to press multiple keys
Do you find it difficult to press multiple keys at once? For example, if pressing CTRL+ALT+DEL is an acrobatic feat, you can set up Sticky Keys. With Sticky Keys you can hit one key at a time in a keyboard shortcut. You can even set it to make a noise so you know it’s working.

You can set up Sticky Keys in Windows 7, Windows Vista or Windows XP. (Hint: Press your “SHIFT” key 5 times in a row, then click on the link, to get going with Sticky Keys in Windows 7 or Windows Vista.)

5. Find a comfortable keyboard
It might also be time for you to evaluate the ergonomics of your desktop. Microsoft offers a full line of Natural and Comfort Curve ergonomic keyboards to ensure you’re comfortable when you’re working on your computer. Having the right keyboard can really make a difference!

Tips for using your keyboard properly

If a new keyboard isn’t in your future, be sure to use your current keyboard properly to avoid soreness or injury to your wrists, hands, and arms. This is particularly important if you use your computer for long periods of time.

Curious about how to create a more ergonomic work space for yourself? Check out these tips to help you work more comfortably and reduce your risk of painful injuries or disorders.

Here are some general tips to help you avoid problems:

Place your keyboard at elbow level, with your upper arms relaxed at your sides.

Center your keyboard in front of you. If your keyboard has a numeric keypad, you can use the spacebar as the centering point.

While typing, use a light touch and keep your wrists straight.

When you’re not typing, relax your arms and hands.

Take short breaks every 15 to 20 minutes.

Type with your hands and wrists floating above the keyboard, so that you can use your whole arm to reach for distant keys instead of stretching your fingers.

Avoid resting your palms or wrists on any type of surface while typing. If your keyboard has a palm rest, use it only during breaks from typing.

Clean your computer

I have a dirty secret. I’ve never cleaned my computer. Sure, I’ve dusted my monitor, but I haven’t taken off the cover or tried to reach the crumbs lurking inside my keyboard.

“Your computer could fry if you don’t keep it clean,” says Jonathon Millman, chief technology officer for Hooplah Interactive.

Dust clogs the vents behind your computer, which causes your CPU to heat up—and heat is the biggest cause of component failure in computers. Regular cleaning could save you costly maintenance fees down the road.

Keep your computer in tip-top shape by following Millman’s guide to a spotless computer system.

Preparation
You’ll need:

screwdriver

can of compressed air (available from computer dealers or office-supply stores)

cotton swabs (do not use a cotton ball)

rubbing alcohol

paper towels or anti-static cloths

water

Always turn your computer off before you begin and unplug all the cords.

Step 1: Inside the case
Using a screwdriver, remove the side of the case that’s opposite your motherboard. Touch as little as possible inside the computer, keeping fingers away from cards and cords.

Blow air around all of the components and along the bottom of the case, keeping the nozzle four inches away from the machine. Blow air into the power supply box and into the fan (from the back of the case). Lastly, blow air into the floppy disk and CD drives. Wipe the inside of the cover with a lightly moistened cloth before replacing it.

Millman recommends doing this every three months if your case sits on the floor, if you have pets that shed, or if you smoke. Otherwise, every six to eight months is fine.

Step 2: Outside the case
Run a cotton swab dipped in rubbing alcohol around all of the openings on the back of your case. Give them one swipe with the damp end of the swab and one swipe with the dry end. Do this as often as you clean the inside of your computer.

Step 3: Keyboard
Turn the keyboard upside down and gently shake it. Most of the crumbs and dust will fall out. Take a can of compressed air and blow into and around the keys. Next, take a cotton swab and dip it in rubbing alcohol. It should be damp, but not wet. Run the cotton swab around the outside of the keys. Rub the tops of the keys. If you have a laptop, follow the same procedure but take extra care with your machine. Do this monthly.

Spills — If you have kids, you’re worried about spills. If it happens, immediately turn off your computer, disconnect the keyboard, and flip it over. While the keyboard is upside down, blot the top with a paper towel, blow compressed air between the keys and leave it to air dry overnight. For laptops, liquid can easily penetrate the hard drive so turn the computer over immediately and and then leave it to air dry overnight.
Laptop spills need more attention because liquid can easily penetrate the keyboard and damage internal parts. For laptop spills, immediately turn off the computer and remove any external power source and other items plugged into it. Turn the laptop over, remove the battery, and then bring it to your nearest repair center to check for internal damage. Simply blowing compressed air into the keyboard and letting your computer air dry upside down overnight aren’t enough because liquids can sit inside a laptop for days.
For all spills, be aware that anything other than plain water may cause severe damage, and never attempt to dry a keyboard or laptop in a microwave or conventional oven.
Step 4: Mouse
Rub the top and bottom of your mouse with a paper towel dipped in rubbing alcohol. Open the back and remove the ball. Wash the ball with water and let it air dry. To clean inside the mouse, dip a cotton swab in rubbing alcohol and rub all of the components. Scrape hard-to-remove grime with your fingernail. Finally, blow air into the opening. Replace the ball and the cover. Do this monthly.

Step 5: Monitor
Moisten a paper towel or a soft, lint-free cloth with water. (You can also buy monitor cleaning products at computer-supply stores.) Don’t spray liquid directly onto the screen—spray the cloth instead. Wipe the screen gently to remove dust and fingerprints. Never touch the back of the monitor.

For laptop screens, Millman suggests buying a special cleaning solution available at computer stores. Do this weekly.

Finally, make sure that everything is dry before you plug your computer back in.

7 tips for working securely from wireless hotspots

7 tips for working securely from wireless hotspots
Wireless hotspots are changing the way people work. These wireless local area networks (LANs) provide high speed Internet connection in public locations—as well as at home—and need nothing more than a mobile PC such as a laptop or notebook computer equipped with a wireless card.

In fact, hotspots are an everyday connection method for travelers and remote workers to browse the Internet, check their e-mail, and even work on their corporate networks while away from the office.

Hotspots range from paid services, such as T-Mobile or Verizon Wireless, to public, free connections. Hot spots are everywhere, including:

Coffee shops

Restaurants

Libraries

Bookstores

Airports

Hotel lobbies

But they all have one thing in common—they are all open networks that are vulnerable to security breaches. And that means it’s up to you to protect the data on your PC. In this article, we cover a few tips to make working in public locations more secure.

Try to choose more secure connections
It’s not always possible to choose your connection type—but when you can, opt for wireless networks that require a network security key or have some other form of security, such as a certificate. The information sent over these networks is encrypted, which can help protect your computer from unauthorized access. The security features of different networks appear along with the network name as your PC discovers them.

Make sure your firewall is activated
A firewall helps protect your mobile PC by preventing unauthorized users from gaining access to your computer through the Internet or a network. It acts as a barrier that checks all incoming information, and then either blocks the information or allows it to come through. All Microsoft Windows operating systems come with a firewall, and you can make sure it’s turned on.

Monitor your access points
Chances are that there are multiple wireless networks anywhere you’re trying to connect. These connections are all access points, because they link into the wired system that gives you Internet access. So how do you make sure you’re connecting to the right one? Simple—by configuring your PC to let you approve access points before you connect.

Disable file and printer sharing
File and printer sharing is a feature that enables other computers on a network to access resources on your computer. When you are using your mobile PC in a hotspot, it’s best to disable file and printer sharing—when it’s enabled, it leaves your computer vulnerable to hackers. Remember, though, to turn this feature back on when you return to the office.

Make your folders private
When the folders on your mobile PC are private, it’s more difficult for hackers to access your files.

Repeat the steps above for each folder that you want to make private.

Encrypt your files
You can protect your files further by encrypting them, which requires a password to open or modify them. Because you must perform this procedure on one file at a time, consider password-protecting only the files that you plan to use while working in a public place.

Consider completely removing sensitive data from your notebook PC
If you’re working with extremely sensitive data, it might be worth taking it off your notebook PC altogether. Instead, save it on a corporate network share and access it only when necessary. This way, you have multiple safeguards in place.

A few simple precautions can help make working in public places more secure. And by selecting the best connections and adjusting settings, you can enjoy productive and safe work sessions no matter where you are.

Start a program using a keyboard shortcut

The Start menu is great for finding programs, but its multiple levels of folders can be time consuming to navigate. If there is a program you start frequently, you should set a keyboard shortcut for it so that you can start the program without taking your hands off the keyboard.

To set a keyboard shortcut to start a program

1.	Click the Start menu, and then click All Programs. Right-click the program that you want to start with a keyboard shortcut, and then click Properties.
2.	Click in the Shortcut key box. Now press the letter on your keyboard that you want to use to start the program. Make it easy to remember—for example, press I for Microsoft Internet Explorer. Note: You can use either uppercase or lowercase letters when creating your keyboard shortcuts—and when accessing them later. In the Shortcut key box, Microsoft Windows XP automatically adds Ctrl + Alt + before the key you pressed. When you want to start the program, hold down both the CTRL and ALT keys simultaneously, while also pressing the letter you chose. This way, your program won’t start every time you type that letter.
3.	Click OK.
4.	Now test your shortcut. Hold down the CTRL and ALT keys, and then press the letter you chose. If you find it difficult to hold down two keys at once, read Turn on the Sticky Keys feature. Your program should start.

When your friends see you start up programs without touching your mouse, they just might think you have a psychic connection with your computer
