Notebook batteries are designed specifically for different notebooks brand as well as models. Today notebooks are powered by lithium ion batteries. Lithium ion batteries are lighter, have a better power-to-weight ratio, can hold a charge longer, have a longer usable life, and do not have the memory effect to fail prematurely.

Lithium ion batteries are also inexpensive to manufacture as compared to the earlier generation of nickel metal hydride batteries. The only shortcoming about lithium ion batteries is as they contain lithium salt dissolved in a highly flammable solvent, there are chances of overhead which can result in short-circuits or even blow up in flames.

It is a common fact that all notebook batteries have provision for limited time of power supply. A good bargain is to check the battery power while buying a notebook. Here is one instant tip to optimize the battery settings in accordance with the energy saving mode of your notebook. These settings will put the hard disk into sleep mode whenever the workload is less and it will reduce the notebook microprocessor performance in order to maximize its battery life.

From the system preferences mode of your notebook, select view menu, then choose energy saver option from view menu. Right click on show details option and choose battery power from the pop-up menu. Finally choose longest battery life from the energy settings pop-up menu.
Tips to optimise your notebook batteries are described in the following:

It is better to keep your notebook on standby mode when not in use for certain amount of time. Standby mode ensures all current info is saved in RAM with minimum consumption of battery power.

It is a good investment to add more memory to your notebook as it saves battery power by reducing Windows’ dependence on the virtual memory swap file on your hard disk.

Try to set the screen brightness of the LCD panel of your notebook to the lowest comfortable level as very bright screen tends to consume more power from your battery.

Charge your notebook battery frequently with a battery charger or AC adapter. It is very important to clean your battery’s metal contacts every couple of months to make it dust free. You can use a cloth moistened with rubbing alcohol to clean your notebook battery.
Turn of the unused features and technologies of your notebook which are not frequently usable. For example, it is better to eject the CD or DVD when you are not using them as the optical drive has the tendency of reading CD or DVD it finds very often and this process consume extra battery power.

Similarly it is better to get rid of the outer peripherals such as printers or digital cameras as they can still draw power from your notebook battery even when they are not used.

Turning off or at least disabling the PC Cards, FireWire devices and USB when not in use also saves battery power. In fact, disabling modem, network cards and USB ports consumes less battery power even when they are on. These devices are easily disabled in device manager.

To save power, it is good idea to turn off the AirPort, Wi-Fi, IR radios and Bluetooth option when it is not required to use. Virus scan should be set only during the time you are usually plugged in as full-disk virus check by the hard drive and CPU consumes additional power from battery.

Opt for the power console applet to customize the power profiles on your notebook. Do not worry in case your notebook does not have power console applet option for most of the operating systems (starting from windows 98) have Power Options utility in Control Panel.

You can use power saver option of your operating system to adjust the CPU processing power. Optimum CPU processes consume additional battery power and hence should be avoided if not required. Stop the auto start applications on your notebook, so that your notebook`s CPU can be stopped from doing unnecessary work.

With the above mentioned handy tips, you can truly increase the battery performance of your notebook.

If you’re a student planning on going off to college, you’re almost certainly considering purchasing a laptop. This is a great idea. As a college student myself, I realize how incredibly useful having a laptop computer rather than a desktop can be. With a laptop, you’re not tethered to any one location for doing your work. You can be in the library, at a friends house, or in lab, and have all your work with you!

In fact, a laptop is probably one of the most important items any student can own. Your laptop will become a much valued accessory during your college years. However, you need to make sure that you get the right laptop for your needs, and thats where this article intends to help. Below are five tips to help you select the right laptop for college, quickly and easily.

1. Know Your Price Range

This is important. Since you’re about to spend a ton of money on tuition, you don’t exactly have a lot of extra cash to blow on a laptop. Fortunately, you can get very usable laptops for very low prices these days, making them more accessible than ever. You may even find that you can buy used to save even more money.

2. Get the Right Size

Size matters. Getting the wrong size of laptop will lead to frustration. To large, and you won’t be able to carry it around easily. Too small, and you won’t be able to get anything done with such a small screen and keyboard. Be sure to try out different sizes to see which ones work well for you.

3. Watch Out For Battery Life

Battery life is a very important factor for the student user. Since you’ll likely be spending a lot of time using the laptop unplugged, you’ll want enough battery life to keep things going. Be sure to check into extended life battery packs that will greatly enhance your battery life at the cost of a little extra weight.

4. Mac vs. PC

This is a huge debate. Don’t buy a Mac just because you think they are cool, be sure that they are in line with your needs. Certain popular software packages do not run on Macs, so if you need these for your course work, be sure to look elsewhere. However, if you like the convenience and ease of owning a Mac, than by all means do so. This article was written on a Mac.

5. Don’t Forget the Software!

Don’t forget to get the software you need! Things like Microsoft Office are pretty essential for every student, so don’t forget to include these in your budget.

So, I hope this helps you see how you can select the right laptop for college. It’s not rocket science (though that could be what you are studying!), but keeping these basic factors in mind can really help out. Thanks for reading.

Dell laptops are a very popular computer they are widely known for quality and good pricing. Toshiba has long been known and respected as a maker of fine quality laptops. Acer laptops have more recently become available and have captured a good piece of the market with their very well priced machines.

All three manufacturers have good selection of models in all price ranges and sizes. Toshiba laptops have always been known for quality and top features. Their price is on average higher than Dell or Acer but the quality is undoubtedly there.

Dell in the last few years has become the biggest laptop computer manufacturer based on sales volume. They have a range of stylish machines which are sought after by many buyers. They even have introduced colored cases which are very attractive.

Acer came on the North American market much later than Dell but have quickly become knowns as suppliers of good,low priced,laptops which many budget minded consumers have found to suit their needs admirably.

Toshiba and Acer laptops are widely distributed in retail outlets whereas Dell has mostly sold factory direct to the consumer. This is now changing however and Dell computers are appearing in large retailers such as Walmart.

The big advantage of Dell factory direct sales is the fact that the buyer can custom build his machine from a wide range of optional features. Toshiba and Acer cannot offer this and the buyer is left with the standard features found in stock at the retail outlet. This is definitely one of the reasons for the popularity of Dell laptops.

Dell laptops selection starts with budget priced models which can be bought for under $500 and goes through middle range modestly priced machines to top of the line very fast big screen models which are sought after by gamers and other buyers who may need,or simply have decided to buy,the fastest and best big screen laptop available.

Acer has expanded their budget priced line into the higher end market of late and also supply laptop computers with fast Intel Duo Core processors and large screen sizes. Toshiba also has a good selection of mid to upper range models to suit the needs of any buyer.

How should you choose between Dell, Toshiba and Acer laptops? One of the best features of the Dell laptop is the custom built machine right from the factory and built to the buyer’s specifications. A wide choice of components is available.

When you buy a Dell computer you select the components you want installed in your machine. The computer is completely built with the components you order and delivered to you with free shipping. The Acer and Toshiba computers cannot give you any choice of components. They have a fixed range of features and you can only buy what is in stock in the computer store.

Toshiba laptops have a well deserved reputation for quality. Toshiba prices tend to be higher on average so they do not appeal to the budget minded buyer. The one major benefit of the Acer laptop is a very good price.

So choose what you see as best for you. Buy a Dell and custom build it with the features you want. Pick your graphic card, RAM memory size, DVD/CD burning drive, hard drive size and so on. The list of features available from Dell is very large. You are buying a real custom machine built just the way you want it.

Buy an Ace or Toshiba laptop and you cannot select the features you want. In fact if you buy any other brand of laptop you do not have this choice available. You may have a lower price than the Dell if you buy an Acer however. If price is your most important determining factor then the Acer may be your choice. The Acer is an extremely popular machine with price oriented buyers.

So that is the story of these three good laptop manufacturers. Dell and Acer laptop computers are made in a price range to suit all buyers. The Toshiba is a great choice in middle to upper price range computers and has great quality.

Due to the great choice of custom features available a Dell laptop has become the desire of a great many buyers. If standard features are right for you then you can save a little by purchasing an Acer laptop and if you want quality and good features in a mid to upper price range then the Toshiba is a good choice.

If you are really after the very lowest price then you should consider a pre-owned laptop. A really good selection of Dell used laptops particularly is always available,if you know where to find them.

If you are thinking of buying a laptop, you have to make sure that you will get what you are looking for and what you are getting. Here are some tips to consider in doing so. I suggest that you meticulously observe these tips.

First of all, performance takes a lot of consideration in buying a laptop, you should choose a laptop that has at least 512 mb of RAM, a fast hard drive, a built in CD/DVD drive, and a card reader. These specifications should ALL I mean ALL be apparent to the unit that you are going to buy. It also should have a dual-core processor.

Then decide on where you will be using your laptop. Will it serve as Ultra-portable(for those who want to carry their laptops everywhere everyday), thin and light, mainstream(cheaper and less svelte versions of their thin-and-light cousins), or as a desktop replacement?

You should also have an understanding of what operating systems are i.e. Windows. Mac OSX or Linux. These are the platforms in which your laptop will be running. I suggest you choose the one you are most familiar with. To avoid confusion on certain functionalities of your unit.

If you have decided to have a laptop that will serve as a replacement for your desktop, choose the one that has at least a 17-inch screen. But if you are a student or a businessman who needs to carry their computers with them always, maybe you can go with the 13-inch to 14-inch screen.

Mobile laptops should only weigh at least 2 (two ) to 3 (three) kilograms if you are planning to carry it around every day.

Also, your laptop should have a lasting battery life. This is a necessity especially when you are on a business trip where you cannot easily plug in your charger anywhere.

Should you need internet services, it is better if you have your laptop ready for wireless connection.

Never forget to buy your own carrying case, where are you supposed to put your laptop in? There are various designs to choose from. Depending on your preference.

I cannot tell you exactly which brand to purchase or what model to buy, because it is still in your discretion on what type of laptop is it that you want to have. But you may want to check out these reliable brands of laptop manufacturers.

Acer, Compaq, Toshiba (a good one), HP(it is ok and cheap), Sony (it is quite expensive but it has a superb performance).

I think you can already have a high-performance laptop with a budget of PHP40,000 (forty thousand pesos).

In conclusion, you have to remember that buying a laptop can be a daunting task. And that your main question will be: “Will it have the ability to take on my daily computing needs?” You may want to check out computer related web sites to further get information on the factors that need to be considered in acquiring your on laptop computer.

Notebook also called as laptop is an extension of desktop computers. It is smart and slick in look, light in weight, consume less power, make nearly no noise and most importantly can be easily carried to anywhere. In fact due to its portable feature as well as with the advent of Wi-Fi features, usage of notebook has been increased rapidly in the last few years.

You do not need to get entangled with wires while accessing internet. Just carry your notebook and enjoy working from anywhere you feel like. Sounds awesome right? Earlier notebook was considered to be a luxurious item which was accessible only among the riches, but not anymore. With the sharp fall in its price, notebook is with in the affordable reach of everyone now.

Even big notebook manufacturers like HP, Dell are quite confident that soon the sell of notebooks will outdo the sell of desktops. These days many notebook manufacturers designed lightweight notebooks also called ultraportables especially for students and business travellers. These notebooks usually weigh less than 3 pounds.

One of the common problems users always complain about notebook is its small screen. Several accessories like DVD burner or 17-inch LCD screen are available by which you can make your laptop screen look every bit as good as your desktop screen. Similarly some users might not be satisfied with the tiny speakers of notebook. You can go for Logitech speaker accessories to enhance the sound capacity.

Some users also do complain about aching fingers when typing long time on a laptop, they can go for wireless keyboard and mouse combo accessories. Imagine yourself in an airport lounge and running out of your laptop battery. Chances are there you might not be lucky enough to find a socket for charging your notebook. It shows the importance of going for a notebook which has long battery life.

These days many notebooks are there with multiple battery options like four cells, six cells or nine cells. Normally more the number of cells, the longer a battery will hold the charge.

All notebook manufactures provide warranty when you purchase notebook of their brand. You also have the option of choosing free at home service in case of any defect occurs with in that warranty period. However notebook is highly susceptible to accidental breakage and theft. So it is a good investment to insure your notebook.

If you think that your notebook does not need to be insured within its warranty period, think again. Because the warranty can at best take care of any defective hardware but theft, fire, power surges or accidental breakage are seldom covered under the warranty scheme. Many electronics retailers do offer extended warranties that act as a kind of insurance. In these extended warranties some retailers offer full replacement of your defect parts. Hence it is a good bargain.

These days you can also go for third party computer insurance agencies that will take care of your accidental claims. Safeware, a computer insurance company covers natural disasters like earthquake, flood and hurricanes under its accidental insurance coverage scheme.

Following are a few tips on how to take proper care of your notebook.

1. Use a clean, soft and lint-free cloth to wipe the dust from your laptop.
