notebook/laptop battery?

how long does a notebook battery usually last? what must i do in so to use the power supply from a power source instead of using battery-power to operate? what would i need?
thanks for the answers, how about the battery from a notebook like HP 540?

The life of a battery is all over the map really. Some can go in as quick as 2 hours. Some can last as long as 8 hours. Thats in the case of a single charge. In terms of the entire battery, it could last 1-2 years or it could last 4-5 years. It fully depends on how many times you recharge it and how you treat it generally.

If you want/need to by-pass the battery, you simply plug in the power cable into the laptop. That's it, nothing complicated. Then it will run on regular current, like any other computer.

How To Choose the Best Student Laptop?

Merchants are singing those three magic words again,

'Back to School' and the fallout is everywhere!

Just as you're getting your deep dark pre-cancerous tan

going -- you hear those words -- and it spells the end

of summer. Once again we are bombarded with advertising,

featuring the latest in 'teen ware' 'school ware' and

'metal detector ware'. Kidding!

Is it just me or does it seem this year there is a lot

more 'Back to School' advertising for notebooks and laptops?

They seem to be everywhere... on TV, radio, and online.

Laptop ads are everywhere. Why is this?

Well, notebooks have come down in price, they have become

more affordable, even for the modest student. Laptops have

also come down in size, making them ideal for that school

napsack, or dormroom. They have also become tougher

and sturdier... better equipped to meet the hard/wear/tear

that students give it.

With notebook technology changing every two years or

so; notebooks can now handle most tasks students throw

their way. These advanced notebooks can do the job. They also

present a much stronger entertainment value to students, they

can handle better graphics and gaming, but most students

try to keep parents in the dark about this factor as they

plead for a new laptop for college or school. All this

pleading is further fueling the demand for laptops.

Then there is a little thing called the Internet. Throw

in a wireless connection and the student laptop is coming

into its own. Big Time!

The Internet has become a second teacher/parent/counselor

to most students. God help us all! But it has also become

a priceless source of the collective knowledge on this planet;

frightening but true. The Internet is an invaluable source of

knowledge for any high school/college student.

Not having ready access to all this knowledge and information

will put any student at a disadvantage with his peers.

It's a very competitive world, in high school, in college and

in the future job market; every student should have an even

playing field.

That's where the little notebook computer enters stage right!

Laptops or notebooks have quickly become a school necessity.

When? How? Why?...

It's the perfect learning tool for students:

* very portable, you can carry them anywhere, class, cafe,

dorm, home...

* very convenient, you can take notes in class, type up assignments, print assignments, communicate home, access the Internet...

* very tough, many newer notebooks are designed to withstand a good pounding and keep on computing, ruggerized for sturdy use...

* very powerful, notebooks or laptops are catching up to their desktop cousins in computing speed, hard drive storage and

performance...

* very affordable, prices have dropped and are falling even further, laptops are now outselling desktop PCs so this price will drop even further, there's a whole slew of used and refurbished laptops hitting the market...

If you're a parent, student, or guardian; here are some of the factors you should consider when buying the best student laptop or notebook:

* size, it must be small, lightweight and very portable, fit comfortably under the arm or in that backpack

* sturdy, it must be tough, sturdy, ruggerized, and able to take more than one hard knock because students are students

* connections, wireless connections should be offered, the Internet is such a valuable tool in itself - a student should be able to access it anywhere. Most notebooks have these connections but check -- a printer port, a 56Kbps-modem, a VGA port for an external monitor, and should have at least one USB port for external keyboard/mouse, digital cameras, drives, and MP3 players

* technical specs, it should have enough RAM, storage space (hard drive) and computing speed to do any job the student can throw at it

* battery life, make sure your student notebook has a reasonable battery life, 5 hours or more

* price, it should be reasonably priced, refurbished laptops may be an option for those on a strict budget

However, some words of wisdom, students or parents shouldn't skimp

too much -- if you're spending 10's of thousands on an education, you

should also provide for the best possible equipment in the form of a sturdy,

lightweight high performance laptop. Besides, a high quality laptop will

last for years... just imagine your son or daughter writing their resumes on

it after they have finished college... keep this image in your mind as you go

about buying that perfect student laptop.

Laptop Vehicle Power

Run comp from cigarette lighter socket?

My battery is dead on an older Compaq laptop. I would like to just use my GPS mapping software in the vehicle without hooking the power supply up to an inverter. Could using one of these cigarette lighter adapters with the proper voltage setting work or could it damage the PC, sine wave patterns and such?

Most laptops have travel chargers that convert from car battery power to laptop power...you should check HP/Compaq's site with the model laptop you have.

Check also Targus' website, they make universal power adapters...

The functionality of solar power is still a new concept to many RVers. Many believe that solar power systems are not practical or that the systems are too complex and expensive.

After one experiences solar power generation, many agree that it is one of the most useful tools to come around in a long time.

The creation of solar power is pretty simple. Solar panels convert light from the sun into energy. The process is known as “photovoltaic process”. The word Photovoltaic is a combination of the Greek word for Light and the name of the physicist Allesandro Volta.

95% of all solar cells are made up of the semiconductor silicone (SI). As light hits the cells, the semiconductor absorbs the light and electrons on the semiconductor are excited creating an electrical reaction in the form of a DC charge. The DC current can then be used immediately or routed to batteries for storage.

Setting Up An RV Solar Panel System.

The components needed to set up an RV solar panel system are:

• A Solar panel
• A Charge Controller
• A Storage Battery
• And an Inverter

Multiple solar panels can be wired together to generate enough power for the needed output. The most important factor when choosing the right panels is the semiconductor material. Crystalline panels produce power more efficiently and have a longer life span than other semiconductor materials.

A charge controller is another piece of equipment needed. The charge controller monitors the batteries and when current is needed, it is supplied in the right amount.

The controllers voltage regulation is needed to ensure the batteries are not damaged by excessive voltage. 12v solar panels can produce voltages up to 19-21 volts depending on the amount of sunlight. Charge controllers are rated in amps. This is the total amount of current is can regulate.

Where To Store The Power For Later Use.

The energy produced by solar panels is normally stored in “Deep Cell” batteries for future use. Deep cell batteries are the favored choice due to the fact that they are designed to be discharged and recharged over and over again.

The amount of power need determines that amount of batteries needed. Batteries are rated in amp hours. For example, a 1 amp hour battery will provide 1 amp of current for 1 hour. Two 150 amp hour batteries in parallel would total 300 amp hours and would provide 10 amps of power for 30 hours. To determine how much power is needed, Add up the total current draw of all the loads on your RV.

The lights in your RV are typically DC and can be operated from the storage battery But most appliances run on AC power. In most cases you will need an inverter. An inverter converts DC power into standard AC current.

Inverters usually come in two types, “True Sine Wave” and “Modified Sine Wave”. Modified sine wave inverters are usually cheaper and can be used to power basic ac power devices.

True sine wave inverters are best for sensitive electronic equipment such as laptop computers, etc. Inverters are rated based on how much power they can supply.

Connecting Solar Panels Together.

Solar panels can be connected together to obtain a higher voltage or power capacity. Connecting two 12volts 5amp panels together in series would give you 24volts 5amps. Connecting two panels in parallel would yield 12volts 10amps. The same is true for batteries.

The panels are then connected to the charge controller. The controller then connects to the batteries. And then the batteries would connect to the inverter. The inverter can then be connected to route AC power to the RVÂ’s electrical outlets.

So there you have it. RV solar panels are great for dry camping or on the go. Solar power is clean, reliable, and the most cost effective means of keeping your batteries charged and the lights on.

The HP Compaq nx6125 notebook Turion 64-bit

Several years ago, when you buy a computer, will undoubtedly be a heavy equipment like a large sewing machine. But advances in technology has been used a small device that is much lighter, faster and a better year than it was well behind.

The HP Compaq nx6125 notebook is a notebook that is packed with features such as security, multimedia, games, and overall performance. The HP Compaq has a hard drive 60 gigabytes that is designed for storage, file storage. Although quite small compared to other laptops. There are some with up to 200 GB of disk space, then try something better.

It is also responsible for films of high security and biometric fingerprint sensor integrated fingerprint, and a Bluetooth connection. These features help keep your laptop from external factors, like people, etc.

Also included are the network connection that is wireless connectivity. As an entrepreneur, who is on the road, get in touch with the world, and others also you can join. She has a FireWire port, about 3 USB ports and a 6-in-1 memory card reader. For those who like to transmit data from memory cards, you just at the right time, this laptop notebook is for you. Personally, I love a laptop where I can connect some devices like camera, camcorder, telephone, etc. and have to HP Compaq nx6125 will be good. I'm off to the mine ...

This notebook is built with an AMD Turion, which is one of the best Smart gaining popularity worldwide. Although this laptop not among ultraportable notebooks we've seen. Its weight is nearly about 6.0 kilograms, which is a bit heavy. But it is constructed in a well, have a scratch resistant body, a spill-resistant keyboard and panel protection system. All this is just to protect it from external factors.

And also for the laptop is not as good compared to computers portable as Gateway, Apple, etc but is built to be durable and resistant. Personally, I like what I see before getting to know what is in it. If not beautiful, at least not in use, so it is not one of my options. But people are different and what matters is different. So for the better.

Laptop Notebook Carrying

What is the proper way to handle a laptop?

I have heard that laptops should not be placed on uneven surfaces or be carried around while on.

But I have seen many people handle their laptops like its a regular paper notebook; they hold it up and move it around while it's still on and open. I especially see this on infomercials where they are selling laptops.

Can laptops (hard drive) handle that kind of movement while it is running? I'm confused.

Thanks.

I would avoid handling your laptop too much while it's running.

Laptops have safeguards to protect against rapid movement, drops, and other ware-and-tare.

Sometimes when stand up quickly with my laptop, the hard drive will click and the sound is never pleasant.

Are you still looking for that perfect holiday gift for that special someone in your life? Are you looking for something that is both stylish, unique, good looking, practical, and healthy? Can such a gift exist? You bet it can! If you know someone who has a laptop computer and who ends up schlepping it around with them everywhere they go, you should really consider getting them a leather computer backpack.

There are lots of reasons why a leather computer backpack makes a great gift. First of all, in today's society, more and more of us are dependent on our computers, and feel naked without them. Between this need to keep our tools and information for business and or school use with us all the time, and the ever more affordable prices of laptops (and now netbooks, which are even smaller, lighter, easier to carry around and even less expensive), more and more people are carrying their laptops to and from work, to and from school, the coffee shop, the library, on road trips... you name it. Heck, lots of people use them as a pseudo baby sitter on long car rides with the kids by letting them watch movies on them.

Regardless of your reasons or situation, the fact is that carrying your laptop around all the time can end up taking a toll on your body, especially if you always carry it on the same side of your body (or have a significant preference, as most of us do). Whether you're holding it like a briefcase in your hand or slung over your shoulder with a shoulder strap, your body is going to incorporate some kind of counter lean to keep you upright. If you do this too much, you're most likely going to start to feel it in your shoulder, hips and or your back.

So what's the solution? Carrying the load evenly distributed across your back with a backpack. This distributes the load evenly across both shoulders and allows you to keep a natural, upright position while also keeping your hands free for more important tasks. If you ask any chiropractor or orthopedic doctor, they will tell you how important it is to maintain proper posture and to not constantly overload the same side of your body when you carry something, whether it be your laptop or your baby.

So now that you understand why a backpack is a good choice for the way in which you carry your computer, you might wonder, 'why a leather backpack?' Actually, you don't really wonder that, do you?

Of course you don't NEED to have a leather computer backpack; any backpack will be a smarter way to carry your computer around. But if you're looking for that really nice, classy, special look for a gift, leather is always going to be a winner, whether it's for a man or a woman. Leather just works. There are plenty of styles, sizes and even different colors. Of course black and brown are the standard colors for leather, but there it's also possible to have fun with other colors of leather such as red, green or white. If you look around enough, especially online, you're sure to find just the right leather computer backpack for that special gift for that special someone.
