**************************************

This is the continuation of a photo-project that I began in the summer of 2008: a random collection of "interesting" people in a broad stretch of the Upper West Side of Manhattan — between 72nd Street and 104th Street, especially along Broadway and Amsterdam Avenue.

As I indicated when I started this project in 2008, I don’t like to intrude on people’s privacy, so I normally use a telephoto lens in order to photograph them while they’re still 50-100 feet away from me; but that means I have to continue focusing my attention on the people and activities half a block away, rather than on what’s right in front of me.

I’ve also learned that, in many cases, the opportunities for an interesting picture are very fleeting — literally a matter of a couple of seconds, before the person(s) in question move on, turn away, or stop doing whatever was interesting. So I’ve learned to keep the camera switched on (which contradicts my traditional urge to conserve battery power), and not worry so much about zooming in for a perfectly-framed picture … after all, once the digital image is uploaded to my computer, it’s pretty trivial to crop out the parts unrelated to the main subject.

Thus far, I’ve generally avoided photographing bums, drunks, crazies, and homeless people. There are a few of them around, and they would certainly create some dramatic pictures; but they generally don’t want to be photographed, and I don’t want to feel like I’m taking advantage of them. I’m still looking for opportunities to take some "sympathetic" pictures of such people, which might inspire others to reach out and help them. We’ll see how it goes …

The only other thing I’ve noticed, thus far, is that while there are lots of interesting people to photograph, there are far, far, far more people who are not so interesting. They’re probably fine people, and they might even be more interesting than the ones I’ve photographed … but there was just nothing memorable about them.

Walking back home at the end of the afternoon, I saw this man sitting alone on the cold stone benches that stretch along the middle of Verdi Square. He seemed lost in thought, and didn’t notice me when I snapped his picture.

Can You Upgrade to some extra effective notebook Battery?

The typical notebook operator must use his appliance unplugged over a typical basis. applications are getting progressively source heavy and as a result drain laptop battery lifestyle faster. Upgrading a laptop’s battery is largely a topic of availability. If there is no enhanced and compatible battery produced for the laptop’s model, you’re away from luck.

Number of Cells
Nine-cell batteries are bulkier than six-cell batteries, but certainly possess a greater cost potential. an individual searching to upgrade his battery really should recognize the amount of tissues the latest battery has. one of the most typical setups use four- and six-cell batteries. customer notebook batteries can have as a great deal as 16 cells.

Battery Composition
All lately produced batteries are composed of lithium ion cells.

The outdated normal was nickel, but any upgrade from this type of a battery is spending inside a new system. Therefore, it is extra vital to appear in the amount of tissues and milliamp-hour (mAH) rating.

Milliamp-hour (mAH) Rating
A notebook battery having a greater mAH rating denotes 1 having a bigger vitality storage space capacity. Aftermarket and non-original producer batteries generally supply compatible batteries which have greater mAH ratings than authentic batteries.

Buying an Upgrade/Replacement
one of the most inexpensive route in discovering an upgrade is via a non-original producer merchant. Non OEM batteries are comparable in superior to OEM batteries. They are also simpler to purchase and much less expensive. They normally are available with 1 -ear producer guarantees.

Installing a manufacturer new Battery(such as dv6700 battery)
Installing a substitution battery is as basic as removing the outdated 1 and inserting the new. However, new batteries have particular methods to follow. See the reference “Laptop Battery Tips” below.

Some Ways To Save Laptop Battery Power When You Really Need It Batteries

You’ve got a five-hour flight from Los Angeles to New York City, and one battery in your laptop. You’ve got work to do, DVDs to watch, and games to play. How are you going to get that battery to last? Well, hidden inside (and outside) your computer are lots of tricks to help you.

Dimming Your Screen

Your screen and hard drive use up more battery power than any other parts of your computer. You can dim down your screen to a point where your eyes still feel comfortable but you also save energy. On most laptops, you first dim the screen by holding down the “Fn” key (go ahead and find it because you may never have used it before). Then you look for a key on your laptop that either has a picture of a sun or a half-moon. (On my Sony Vaio that key happens to be F5.) If you find it, go ahead and hit it while still holding down the Fn key. A brightness adjustment box should show up on your screen. If you can’t find a key with a sun or half-moon on it, try hitting your various arrow keys while holding down Fn, to see if that works.

Turning Off Your Screen Altogether

If dimming your screen is good for saving battery life, turning it off when you’re not using it is even better. To turn off your screen, we’re going to have to go into some settings in the Control Panel. You’ll soon see these settings are not only good for turning off screens; they perform a whole host of battery saving functions.

Click on Start, then on Control Panel. If your Control Panel is shown in the “Category View”, click first on Performance and Maintenance, then on Power Options. If your Control Panel is in Classic View, simply click on the Power Options icon. Next click on the Power Schemes Tab. Underneath where it says Running on Batteries and across from where it says Turn Off Monitor, choose how quickly you’d like your monitor to shut off when you’re not actively using it.

That Power Options Properties box we just opened brings us to a whole host of other enticing options we can employ on our cross-country flight!

Choosing a Power Scheme

Windows XP offers two Power Schemes appropriate for laptops on the go. These are Portable/Laptop and Max Battery. They can both be chosen in the Power Schemes tab of the Power Options Properties box. Both power schemes conserve battery power. But Portable laptop adjusts what it conserves to the amount of power you need at the time, while Max Battery is much less flexible. It keeps your computer at a very low constant power rate no matter what you may be doing. So if you are planning on watching a DVD on that flight, which uses a lot of battery power, I don’t recommend using the Max Battery power scheme. It might not give you enough power.

Each power scheme also has its own settings for when the monitor and hard disks should be turned off. Remember that both are huge energy hogs, and that both the monitor and hard disk remain on longer under Portable/Laptop than they do under Max Battery.

The power scheme you choose also determines how long the computer will wait to go into Standby mode or Hibernate after remaining idle. Standby conserves energy because it turns off your hard disk and monitor. However, whatever you were working on at the time stays in memory (RAM) instead of being saved safely to your hard drive. The upside of Standby, though, is that when you press any key your computer will come out of the mode rather quickly.

Hibernation saves even more energy because it saves your work to the hard drive and then shuts your computer down almost all the way. Inherently, of course, this means it takes the computer longer to wake up to its normal state, but when everything does come back on, it looks the same as before. To switch your computer to Standby mode manually, click on Start, then on Turn off Computer, then on Standby. To make your computer Hibernate manually, click on Start and Turn off Computer again, but this time hold down the Shift key down afterward. The Standby key switches to “Hibernate”. Click it and your computer will go into Hibernation mode.

Creating Your Own Profiles

Maybe you don’t like the two power saving choices Windows gives you. Maybe you want to create custom ones to suit your own needs. You can do that! I created one for “Long Plane Rides”. I adjusted the settings in the Power Options Properties box. For instance, I indicated I wanted my monitor to turn off after only 2 minutes of idle time, and my hard disks after 3 minutes. Then I clicked on Save As, named my profile, and clicked OK. Now maybe the battery will last even longer on the flight.

Let’s go through some other choices in the Power Options Properties box. Under the Alarm tab, you can check boxes to either be alerted when your battery is low and/or when your battery is critical. You can even use the slider to make your own determination of just what is low and what is critical. Then you can click on Alarm Action to tell your computer to, for instance, sound an alarm or go into Standby mode when those moments are reached.

Under the Advanced tab, you can choose what you want your laptop to do when you close the lid. You can choose it to go into Standby mode, Hibernation, or even do nothing if you wish. You can also choose what you’d like the computer to do when you hit the power button.

If you’re interested in using your laptop’s Hibernation feature you should check the box under the Hibernation tab that says Enable Hibernation.

Turn Off Wireless Network Card

Your wireless card can also be a drain on your battery’s resources, so disable it if you don’t need it. (You don’t need it obviously on a plane, for instance.) If your laptop has a wireless card, simply take it out. If your laptop has wireless built-in, you can disable it in Windows XP by clicking on Start and going to your Control Panel. In Category View, click on Network and Internet Connections, then Network Connections. In Classic View, simply click on Network Connections. Once you’re there, right click on the wireless connection you’re using, and click on Disable. You can also disable your wireless network card through the Device Manager. Right click on My Computer and left click on Properties. Click on the Hardware tab and then the Device Manager button. Next, click on the small black cross next to where it says Network Adapters. Locate your wireless network adapter, right click on it, and left click on Disable.

You can also left click on Properties instead (after you right click on your network adapter), click on the Power Management tab, and check the box that says “Allow the computer to turn off this device to save power”.

Some newer laptops with the Intel Mobile Pentium® chip have a button somewhere on the laptop itself, for instance on the front, to enable you to easily turn your wireless on or off. You may have to check your laptop’s manual to find out if you have a button and if so, where it is.

CPU Throttling

The Intel Mobile Pentium® laptops also sport a feature known as CPU Throttling (and named SpeedStep™ by Intel), that actually slows down your processor when you’re running on the battery. When you’re plugged into your AC, your processor runs full speed ahead. But when you unplug that cord, it shifts into a lower gear. A processor running at a lower speed and using less voltage saves your battery even that much more juice.

So now you have a number of tools to implement in order to save your computer’s precious battery power. But maybe instead on that next long distance flight, you might want to think ahead and book a seat with a power outlet.

Some Tips to Extend Your Laptop Battery Life

Some Tips to Extend Your Laptop Battery Life

You seasoned techies are no doubt thinking, “Another article on how to get more life from your laptop battery. Big deal. I already know how to do that.” Well, Mr. or Ms. Techie, I scoff at your hubris. There’s still plenty to learn when it comes to getting more juice from a charge and extending your battery’s overall life.
So, yes, there are tips that most of us know:

Dim your screen.
Minimize background processes.
Don’t use the CD/DVD drive.
Disable your wireless antenna when not in use.

But there’s still a lot you may not know about laptop battery technology and the things that both help and hinder your laptop’s juicebox.
Getting More Minutes per Charge
You can fiddle with background processes and other software settings all you want, but your hardware is the biggest factor in laptop battery life, according to PC Mag’s lead analyst for laptops, Cisco Cheng. In fact, software such as power-management utilities can help minimize the impact internal components have on battery longevity. Knowing this can affect your buying decision if you’re looking for a new laptop (see the “Picking a Laptop for Maximum Battery Life” section below) or help you get the most out of the trusty laptop you’ve got. Here are a few ways to optimize hardware for maximum battery output.

Turn off ports. Disabling unused ports and components, such as VGA, Ethernet, PCMCIA, USB, and yes, your wireless, too. You can do this through the Device Manager or by configuring a separate hardware profile (see next step).
Create Power-Saving Hardware Profiles. Configure your laptop for the various scenarios in which you use it (on a plane, at the coffee shop, at the office, and so on). You can do this through the Hardware Profiles menu by right-clicking on My Computer and selecting Preferences or by using a freeware utility such as SparkleXP (for Windows XP users).
Configure your display to turn off when not in use. This is different from just using a screensaver, because in many cases a screensaver still requires the display’s backlight to be on. You can set the interval to turn the display off in Windows’ Power Options—found in the Control Panel.

Extending the Overall Life
The easiest way to give your battery an early death is to damage it. And the two most common causes of damage are from overheating and using an AC adapter with the wrong voltage. For that, make sure to check the voltage of your adapter, especially if using a replacement adapter. Here’s how you prevent overheating:

Use a cooling pad when using a notebook computer on your lap.
Avoid propping your laptop on a pillow, blanket, or other soft surface that can heat up or block cooling fans.
Clean your desk. It sounds strange, but if you have a dusty, dirty desk, that dust will get into the vents and clog the cooling fan. Once the dust is inside your laptop, it is much harder to remove. You can try blasting it out with canned air, but you run the risk of damaging internal components. You can also remove the vent and clean out the grit, but remember that taking apart your laptop can void the warranty. So clean your desk at least once a week, if not daily.
Try not to store your laptop in a place where the air temperature exceeds 80 degrees Fahrenheit, such as a hot car or an outdoor patio. And if your laptop heats up or is cold, let it return to room temperature before starting up.
Consider taking your battery out when using your laptop plugged into AC power. Just make sure to keep the contacts clean. If you need to clean them, use rubbing alcohol.
For lithium ion batteries, you do not need to discharge them fully and recharge constantly. Since they don’t have the same “memory” as older nickel-metal hydride batteries, it is actually better to discharge a lithium ion only partially before recharging. You need to do a full discharge only about every 30 charges.

Picking a Laptop for Maximum laptop Battery Life
If you’re in the market for a new laptop, there are features and components you should consider to get the most mileage from the system’s battery.

An ultra-low-voltage processor, such as the Intel Penryn or one from VIA’s line of ULV processors.
A solid-state storage drive, which requires less power and, since there are no spinning parts, will suffer less wear and tear than a traditional hard drive.
An LED display. Although pricey, LEDs use much less power than LCD.
A smaller screen. A smaller screen means a smaller backlight, which will also save on battery drain.

According to Andrew Bradner, product line manager for APC, all lithium ion batteries are not created equal. The proof is in the pudding, or in this case the chemistry. Unfortunately, it is almost impossible to discern if the battery you’re buying was manufactured in a top-notch facility using high-quality materials. And making that call is not as easy as assuming your laptop manufacturer’s battery will be of better quality than a battery from a third-party vendor. But you can stick to a couple of key guidelines.

Don’t skimp on your battery. If you choose the lowest-cost battery you’ll probably get a battery that degrades quickly, and you’ll end up buying a replacement too soon anyway. So spend the money now to save expense and frustration down the road.
Don’t buy an expired battery. A good indicator of a battery’s performance is how far into its product life it is, whether it’s used or new. If possible, look at the bottom of the battery and find the manufacture date.
