Although many people ignore it, the battery life is one of the most important parts of your laptop, unless you use your notebook for non-portable purposes. The average life of a notebook battery is between two and three hours. Unfortunately, most batteries don’t even stand for their minimum reference.

When I bought my laptop, they said that the battery will stand for three to four hours, but it actually stands for much less… What am I supposed to do?

The question now is how do you increase your laptop battery life?

The article will be giving you a few tips to help you extend your laptop battery life.

Optimize the Power Options

You might be expecting me to tell you to go and install one cool software or to go and buy one external gadget, but the reality is that your laptop already has enough to make it last even longer than it currently is.

All you need to do is optimize your laptop battery and select the right options. For example, with my HP laptop there is the “Balanced Power Option” and the “Power Saver Option”.

The balanced mode is the main option while the power saver mode will disable some system components in order to ensure I get more from my laptop.

This options vary depending on your laptop, and you can easily do it manually by disabling some components like your CD, by not making use of any external device and by dimming your computer brightness – this alone will help you increase your laptop battery by at least 10% and it will also ensure it last longer than the average laptop battery.

Don’t run a lot of Applications at the Same Time

The next step you should take is to ensure that you’re careful with how many applications you install and run on your computer at the same time.

If I were to ask, how many laptop applications do you run on your computer at the same time? How many programs do you use at the same time? How many of these programs are really necessary?

Try to ensure you avoid using your laptop for multitasking while at the same time cutting down the average number of applications you use in a day and you’ll be surprised to see a significant increase in your battery life.

Upgrade Your Computer Memory

How a computer functions depends on several components of the computer. The most important component that influences the work of a computer however is its memory (RAM).

A great way to save your laptop battery life is by ensuring it is able to perform a lot of operations in a short period of time and the only way to do this is by upgrading its memory.

Upgrading your laptop memory will also make it easy for you to play high graphic games, use a lot of applications and do a lot of things without your laptop being affected.

While testing their battery life, most companies are trying to avoid loading high performance on their CPU, HDD and graphics memory, while you are using a huge part of your resources. You could always think about saving some battery life. Here are some effective tips on how to increase your battery life while not charging:

Dim your screen- You can always turn down the brightness of your screen, depending on the light in your room.

Turn down the volume- The volume needs a lot of energy. Turn it down if you are not using an external device with independent battery/charger.

Turn off unused laptop features - For example Bluetooth, or Wireless if you are currently not connected to the internet.

Turn off unused applications and processes - End the background applications that are not in use at the moment. You can monitor the resource usage of all running processes through the “Task Manager” - Ctrl + Shift + Esc..

Also, if you are not connected to the internet, you can feel free to shut down or temporary disable your firewall/anti-virus software.

Schedule Windows updates - While trying to save a battery life, it is not the best time to update your windows. Run these updates when you are charging your battery.

Another big mistake that laptop users always assume is charging the laptop even when its battery is full. Remember: It is recommended to unplug your charger when your battery is full. By this way the battery will get more “training” on its consummation.

What is the difference between sleep and hibernate?

While your laptop is “sleeping”, your display and hard drive are turn off. Currently running applications are stored in your RAM, while in hibernation, the applications data is saved to your hard drive. So, use the hibernate mode instead of sleep, because in hibernate mode, your laptop is completely using no power. You may have noticed that in sleep mode your laptop can be woken accidentally, which is another advantage of the hibernate mode.

If you believe the headlines, the first rule about buying a laptop today is to forget about buying a laptop today. These bloated, annoying, space-hogging gadgets are apparently painfully obsolete compared to modern, sleek and sexy tablet computers. But just hold on a minute! Laptops still outsell tablets four to one, and sales in 2012 are expected to top a quarter of a billion worldwide for the first time ever.Laptops are faster and more powerful than tablets, have convenient full-size keyboards, are easy to connect to printers and cameras, and can glide between work and games in a flash. (Plus they can all actually run Flash.)If you want an affordable, practical digital all-rounder, laptops come in an array of shapes, colours and prices that make flat, grey tablets look boringly identikit. There are laptops for students, laptops for artists, even laptops for mountain climbers. The only drawback to this variety is that it can be all too easy to end up with a computer that’s either under powered or overpriced for your needs.

First things first

You’ll need two things when shopping for a laptop: a clear idea of what you want to do with it; and a firm budget. The good news is that all new laptops will be fine for checking email, surfing the Web wirelessly, working on office documents, and enjoying your photo and music collections. Where things start to get trickier is if you’re heavily into gaming, want to watch (or edit) HD video or need a computer that works well away from power sockets or in extreme conditions.

Fix a budget before you start browsing — although leave a little wriggle room for extras like a laptop sleeve, software, a separate mouse and possibly an external hard drive.

The basics

Laptops come in three categories. At the small and portable end are ultra-lights, designed for stressed-out executives formatting Excel spreadsheets on the Heathrow Express. Not to be confused with budget netbooks (we have a whole buying guide just for them), ultra-lights tend to be nicely designed, a little sluggish and shockingly expensive. Their screen sizes range from around 11.5 inches to 13 inches.

The next step up is everyday laptop computers, sometimes called notebooks, with screens from 13 inches to 15 inches. This is the sweet shop for laptops, where the most are sold and prices are keenest. Notebooks are light enough to carry occasionally and can usually manage half a day’s work away from power, but budget ones often lack style, speed and build quality.

The final category is multimedia (or desktop replacement) laptops. These monsters have screens up to 17 inches (and sometimes even larger), and come packed with smart graphics cards, super-fast processors and lots of memory. They’re the first choice of gamers, graphic designers and anyone who wants the power of an old-school desktop squeezed into a portable body. Well, we say portable, but these laptops can be heavier than a case of duty-free and bulky enough to need a Business Class seat to themselves. 

Windows or Mac

]]>

Switch on the telly and it seems that everyone using a computer has an Apple Mac, except perhaps those hardcore hackers you see surrounded by monitors, empty pizza boxes and Star Wars figurines. In real life, however, the choice is not quite so clear-cut.

Macs are built well and age slowly but cost at least two to three times as much as the cheapest Windows machines. Even at those prices, the most affordable MacBooks have cramped screens and some performance limitations. Windows computers offer more choice and lower prices, but you’ll need to stay on top of upgrades and security to get the best from them.

When shopping for a PC laptop, insist on Windows 7 software. It doesn’t really matter which version, although anything running the Starter Edition is actually a netbook rather than a laptop — hop over to our netbook buying guide for more info.

A bigger decision is what brand to buy. Unlike desktops, where even no-name companies can make great computers, the technical challenge of squeezing hundreds of components into a tiny case favours multinationals. Stick with top electronics brands (such as Sony, Samsung, Panasonic and Toshiba) or laptop specialists (Acer,Asus, HP/Compaq, Dell). Some retail chains also have ‘in-house’ brands that can be good value, if a bit plasticky.

Tech specs

Laptop specifications change all the time and consist of a brain-melting alphabet soup of letters and numbers. In general, there are three things to consider: the processor; memory (RAM); and storage. You can ask about other key components, like the graphics card and graphics memory, but don’t expect to understand the answer — check the model online if this is important to you.

Processors are virtually all dual-core these days, and are usually made by either Intel or AMD. There’s little to choose between the two, although AMD silicon tends to be found in cheaper machines. Intel chips get more powerful as their model number increases (ie. an Intel Core i5 chip is faster than an Intel Core i3).

Processor speed, quoted in GHz, affects how fast it can crunch numbers. Anything above 2GHz is fine for everyday use, but gamers and video fiends should look for higher numbers, and especially for Intel’s Turbo Boost feature.

RAM is the other thing that affects how fast your laptop runs. 2GB is an absolute minimum these days — and step up to 4GB (or even 6GB) if you can possibly afford it.

Hard decisions

Hard drives generally range between 250GB (miserly) to 1,000MB (1TB, gargantuan). These determine how much data, including music and video, you can store on your laptop. Always buy a little more storage than you think you’ll need, but don’t bankrupt yourself. External drives are getting cheaper all the time, and space-saving cloud services are increasingly popular.

Apple’s MacBook Airs, and some high-end Windows laptops, have fancy solid state drives that are faster, tougher and use less power. They’re also achingly expensive and come in smaller capacities.

Screen and build quality

Always try to get your hands on a laptop before you buy. Start by looking at the screen indoors and — if possible — near a window or outside. You’ll probably find that Apple and Sony screens have the brightest colours and best contrast. If you do have to buy from the specs alone, look for LED backlighting and Full HD for the best resolution, found on pricier machines.

’3D’ is a buzzword right now and 3D laptops are already trickling out. While games and films can look stunning in 3D, the technology is still fairly young, fairly expensive and suffers from low levels of brightness and sharpness. Consume at your own risk.

Don’t underestimate the importance of a good keyboard, trackpad or navigation nipple. Look for dedicated keys for mail, Web and especially media controls — they all make smaller keyboards easier to use.

Open and shut the case a few times and hold it in both hands. How heavy is it? Does it flex or creak? How strong does it feel? While it’s hard to beat Apple for solidity and design, all the big brands have premium metal-bodied models, and Panasonic even has fully waterproof and toughened Toughbooks.

In and out

The best laptops have a choice of connectors, including multiple full-speed USB ports, HDMI sockets for linking to media systems and memory card readers. Some laptops will have DVD or even Blu-ray players, although these add weight and suck power. A built-in webcam is great for Skype, Facebook or FaceTime video calls — don’t worry about its resolution.

Spare a thought for the battery powering all this techno wizardry. Manufacturers’ battery life figures are a rough guide, but take them with a pinch of salt and don’t expect to achieve day-long use without resorting to a socket. If you simply must have mobile freedom, choose a laptop with a replaceable battery and buy a spare immediately — they can be hard to find a year or two down the road.

Ultrabooks

Finally, keep an eye out for ‘ultrabooks’, a new term coined by Intel to describe ultra-thin PC laptops rivalling the MacBook Air. Expect machined metal cases, solid state drives and even touchscreen displays to make the most of new finger-friendly Windows 8.

You can read our reviews of some of the first ultrabooks, including the Asus Zenbook UX21, the Toshiba Portege Z830 and the Acer Aspire S3.

Keeping Laptops From Getting Lost or Stolen

A laptop computer defines convenience and mobility. It enables you to work from home, a hotel room, a conference hall, or a coffee shop.

Maybe you’ve taken steps to secure the data on your laptop: You’ve installed a firewall. You update your antivirus software. You protect your information with a strong password. You encrypt your data, and you’re too smart to fall for those emails that ask for your personal information. But what about the laptop itself? A minor distraction is all it takes for your laptop to vanish. If it does, you may lose more than an expensive piece of hardware. The fact is, if your data protections aren’t up to par, that sensitive and valuable information in your laptop may be a magnet for an identity thief.

Chances are you’ve heard stories about stolen laptops on the news or from friends and colleagues. No one thinks their laptop will be stolen– at least not until they find the trunk of their car broken into, notice that their laptop isn’t waiting at the other side of airport security, or get a refill at the local java joint only to turn around and find their laptop gone.

]]>

Here are some tips to keep your laptop safe:

Treat your laptop like cash. If you had a wad of money sitting out in a public place, would you turn your back on it – even for just a minute? Would you put it in checked luggage? Leave it on the backseat of your car? Of course not. Keep a careful eye on your laptop just as you would a pile of cash.
Keep it locked. Whether you’re using your laptop in the office, a hotel, or some other public place, a security device can make it more difficult for someone to steal it. Use a laptop security cable: attach it to something immovable or to a heavy piece of furniture that’s difficult to move – say, a table or a desk.
Keep it off the floor. No matter where you are in public – at a conference, a coffee shop, or a registration desk – avoid putting your laptop on the floor. If you must put it down, place it between your feet or at least up against your leg, so that you’re aware of it.
Keep your passwords elsewhere. Remembering strong passwords or access numbers can be difficult. However, leaving either in a laptop carrying case or on your laptop is like leaving the keys in your car. There’s no reason to make it easy for a thief to get to your personal or corporate information.
Mind the bag. When you take your laptop on the road, carrying it in a computer case may advertise what’s inside. Consider using a suitcase, a padded briefcase or a backpack instead.
Get it out of the car. Don’t leave your laptop in the car – not on the seat, not in the trunk. Parked cars are a favorite target of laptop thieves; don’t help them by leaving your laptop unattended. That said, if you must leave your laptop behind, keep it out of sight.
Don’t leave it “for just a minute.” Your conference colleagues seem trustworthy, so you’re comfortable leaving your laptop while you network during a break. The people at the coffee shop seem nice, so you ask them to keep an eye while you use the restroom. Don’t leave your laptop unguarded – even for a minute. Take it with you if you can, or at least use a cable to secure it to something heavy.
Pay attention in airports. Keep your eye on your laptop as you go through security. Hold onto it until the person in front of you has gone through the metal detector – and keep an eye out when it emerges on the other side of the screener. The confusion and shuffle of security checkpoints can be fertile ground for theft.
Be vigilant in hotels. If you stay in hotels, a security cable may not be enough. Try not to leave your laptop out in your room. Rather, use the safe in your room if there is one. If you’re using a security cable to lock down your laptop, consider hanging the “do not disturb” sign on your door.

The most important tip:

Safe guard your computer with Anti-theft software.  Anti-theft software helps you in the event that your laptop is stolen.  It does a number of things such as:

-        Encrypts your files and locks down the laptop when stolen

Did your old computer just break down due to long time use? Do you need a new one to help you perform tasks the easier and faster way? Since there are a lot of things to consider when buying a laptop, it is advisable that you ponder on a lot of things first before proceeding with your choice. This way, you can get your money’s worth on such an expensive product.

There are different types of laptop in the market but it takes a good one for you to fully maximize its function. Investing in the one that does not fully meet your own standards might cause you some disappointment and regret in the long run. Here are some ways for you to choose a laptop that really suites your need:

1.      Jot down the top 8 qualities you are searching for in a laptop. List down 8 preferences you are looking for in a laptop. This way, you can contain your choice in specific qualities of a computer that can prove beneficial for you in the long run. Remember, you will be using the gadget for a long time and it is important that you are fully satisfied with your own choice.
2.      Do some window shopping. Out of the large supply of laptops in the market, your list serves as your guide in choosing for the right one. Do you want it small? You might want to consider notebooks. You want it to be of standard size? Go for regular-sized laptops. If you specifically want a Mac, you might want to head out into the nearest store and contain your choice in that one (if you really are considering an Apple product, make sure that you have enough money to buy for it).
3.      Ask from the sales clerk. If you are alone and let’s say, not that “tech-savvy” then you might want to ask a little help from the store manager or a sales clerk. Pull out your list and ask the other person if they have a certain product that seemingly fits what you are looking for. Yes, it can be embarrassing, but it’s worth the try!
4.      Budget and contemplate. After having a certain laptop in mind, it’s time to think about money. Are you willing to spend a lot of cash for the laptop that made it to your top list? If you think it’s all worth it, then buy it!

Your satisfaction counts a lot! But along with it, you also have to consider the quality of the product you are willing to spend your money on. Good luck with your choice! Happy shopping!

Now, a laptop is one of the most common gadgets people need nowadays. Because it is portable, you can bring it along with you everywhere you go. There’s no need for wires and cables, just a few features you can trust yourself to rely on when it comes to making your life easier. Here are some ways for you to select a good laptop that fits you:

1.      Purpose-specific. Ask yourself, for what purpose are you buying a laptop? Is it because you want something to help you with your school works? Is it needed for your job? Do you want to have one just because you want to play games on it? If you’re a student, you might consider small ones or notebooks since they fit conveniently inside your bag. However, if you are working on a company, or if you are a graphic artist, you might want to choose laptops because of their high memory capacity and better screen resolution. If you are fond of playing games, a good screen resolution also counts important.
2.      Think of the memory. The bigger the computer is, the better is its storage and memory capacity. Have you ever opened a lot of tabs and you encounter the “not responding” icon? Well, it shows that you have high memory usage and your computer has a difficulty of accessing different tasks at the same time.
3.      What about the CPU processor? The processor of your CPU determines the rate of performance of your laptop. Some computers tend to lag behind while there are also others that function at an impressive rate. Think of Core 2 Duo, it is fast and good enough especially when you want a good processor.
4.      Battery life. One of the main reasons why you need to purchase a laptop is the fact that you can use it even when no power connection is present. Now, battery life matters a lot. A computer with a fast processor and a large storage capacity tends to consume more power. If you still prefer a laptop rather than a notebook, then you can adjust the settings of your battery power plan. However, if you maximize the battery life, your system performs at a slower rate than the usual.

There are a lot of portable computers that have taken the market by storm. In this new age of technology, having one denotes not just a need, but a common necessity. Since this gadget is expensive, it is important that you carefully choose the one that is not just attractive in design and built, but also made of the finest quality that can last for a long time.

Now, there are different things that make a good computer. If you are not updated with all the latest information about technology and computers, still you need to know some of the details in order for you to choose wisely the one that worth your penny.

Here are some common characteristics that a cheap laptop computers should possess:

Impressive built and durability. Let’s face it, we all want our things (especially expensive ones) to last for a long time. Otherwise, what is the purpose behind spending a hundred or even a thousand bucks for it, right? Some laptops are built to last while others just seem to break down with the slightest rough handling.
Better memory storage. It is best to inquire first about the memory of the laptop computer before jumping into making a purchase. The memory of the computer counts as the major reason why it can hold a lot of programs, files and applications all at the same time. Bigger computers also have bigger memory while smaller ones also have lesser capacity. It follows that notebooks have lesser memory storage in comparison to regular-sized cheap laptop computers.
Impressive CPU processor performance. Let’s say you don’t have any idea what a processor is. How do you know which chip does your laptop computer possess? The name of the chip is usually plastered on the keypad area. Familiar with Intel Core 2 Duo? Celeron? AMD? Now, does it ring a bell? Core 2 Duos and AMDs are impressive enough when it comes to performing varied tasks without all the slowing down.
Great screen resolution. The pixels of your own screen affect how the colors are highly represented. There are different laptops boasting of HD resolution, but these are only 720p compliant screen. If you want an impressive one, you can go for computers that are more than 1080p. This is a good especially if you are planning on using your laptop for gaming purposes.

Although all of these qualities may not be present in the laptop of your choice, it is still important that you carefully verify the product before you jump into buying it in an instant. This way, you get to have your money’s worth for a good investment.
