Refurbished Compaq Laptops

If you are in a look-out for a budget laptop computer, then you have some companies to focus on and one of them is Compaq Presario. It is not actually a main company, as HP took over it a couple of years ago and since them the name has been kept and smaller prices are available. For instance, you can get a brand new laptop computer for less than $400, with the basic configuration and just the features you need for everyday tasking such as browsing the internet, checking your e-mails, go on social networks, chat with your friends, manage your files and edit documents. You can also play some basic games and watch videos and movies when in need of some entertainment. But if you really want to lower down the prices, then the solution would be to buy a refurbished Compaq laptop. You can find such systems online and the variety is pretty large as factory refurbished are not rare things anymore.

Some of the refurbished laptops can have physical damages, such as scratches and so and the parts inside have been tested before twice, to make sure the system is functional. If you buy from online retail stores, then you can read the description and learn more about the product. But in case you buy from another user or unreliable website, then perhaps you don’t even get a warranty and you never know if all parts are inside and the real state of the laptop. And if you pay cheap in any case, you should watch yourself and buy genuine products, as refurbished systems are valuable and most users are satisfied with their purchase. So, if you are interested in them, let’s go through some of the models online and you will see for yourself the specifications and what can such a system manage.

For just around $250 you can buy Compaq Presario CQ62-219WM factory refurbished, that handles the basic computing and provides on the go experience. The classic looks are just what you need to blend in any environment. The key features of this model are represented by: the Intel Celeron 900 processor, 2GB DDR2 SDRAM system memory, which you can expand later on to 8GB, so you improve performance and speed in processing, a 250GB hard drive SATA, Super Multi DVD Burner, wireless LAN and a 15.6” HD HP BrightView LED display. The warranty is limited for 90 days and you get software pre-installed as well as Windows 7 Starter and finally, a 6-cell lithium Ion battery that will hold for a couple of hours considering the tasks you will manage are basic.

If you are in need of something a bit lighter, then Compaq Evo N600c is a 14.1” system you can see. It comes for around $300 and it packs the basic features, less performance compared to earlier, but this is one model you can trade, because you will not get too much out of it. The looks of it are not such “modern”, so perhaps you will not like it. But it was just to give you a point of view of what you can find online and the prices you should expect to pay.

Sony Laptop Repair

At one point in a lifetime of a laptop computer, any kind of that matter, issues appear and you will face the situation when a repair must be done. It all depends on the problem that causes you to not be able to work on your system. It can be a software issue or a hardware one, both being questionable repairs, taking in account that some damages are permanent. If you are at the office and your Sony laptop shuts down and so, you simply call the IT department and wait for them to fix everything, but if you are sitting at home, then you need to do some work and spend some money on parts and so. In most cases, a Sony laptop repair can be caused by the battery or by the hard drive, related to hardware issues of course. If you decide to manage thing yourself, you save money, but you still have to get a new hard drive or a replacement battery. And for the screws you will need a small Philips screwdriver.

For the battery repair, just shut down your laptop computer and see if the battery light goes red. If not, then the battery is the one to blame. Try again to connect the AC adapter and see if the laptop powers up, if yes, then it is related to the battery. Just lift the battery cover and move the switch in the unlock position. Now you can slide the battery out and put it aside. Get the new battery you bought (making sure at first that you buy the compatible one) and slide it inside its compartment, making sure the connections are in the right way. Moreover, lower the cover and move the switch back in the lock position” so you seal the compartment. Let the battery fully charge for a couple of hours, then unplug the adapter and reset the system. If the Sony laptop powers up, but it just doesn’t start, then the hard drive is the problem, as it is one of the main components and the computer can’t run without one.

Now, in order to change the hard drive, you have to remove the battery and open the hard drive cover on the underside of the laptop, in the right corner to be more exact. There are five small screws that you should remove first. Now you can remove the hard drive bracket, but see the two screws here again. Carefully lift the hard drive out on one side and unplug it from the motherboard connector. The cable needs to be removed as well and the mounting brackets for the hard drive should be fitted to the new hard drive you bought. Remove the brackets from the old hard drive and place them to the new one using the same screws and the same locations. Now just reconnect the hard drive cable and slide the hard drive in its casing, plug in the the motherboard, the housing and put back the screws.

Finally, restart your Sony laptop and run the system recovery disc, following the instructions in the setup wizard. Now the computer should run normally again and should be able to save your files and keep them. These are some of the Sony laptop repairs you can manage, but remember that the case depends on the situation.

Sony Laptop Battery

Let’s be honest, the real reason people buy a laptop computer is due to portability. It doesn’t compare to anything just to be able to grab your portable system and hit the road, even during a short travel just watch some videos, manage video chatting, connect to the wireless internet while you are having a coffee and read the morning news and so on. And when it comes to companies that provide laptops, Sony Vaio is one of them and it managed to be different and to attract certain type of users, mostly those looking for high-end machines. This is because the cost of a Sony Vaio laptop is mostly higher than the rest, plus the looks help the situation a lot. A battery inside a laptop is not meant to last forever. After even one year you can see that it doesn’t hold on like at the beginning and it drains faster. At one point you will be enjoying just around half an hour or less, which is mediocre and it isn’t worth taking your Sony anywhere outside the house.

So what can you do when your Sony laptop battery doesn’t hold on anymore? You simply replace it, as you can find replacement batteries all around the internet, on the company’s website, electronic stores and so on. The price depends on the type of laptop you have and how many cells it has inside. Without question, you should always make sure that you buy only compatible Sony laptop batteries, compatible with the serial number of your system. You can check the manual to see exactly what to buy. And as for the replacing part, you can do it easily in a couple of seconds as long as you follow some simple steps, so here it goes. First of all, place your system on a flat surface, upside down and hold the switch near the battery in the open position. Slide and hold the release switch on the battery in order to lift it. You can do so using the depressed tab on the pack. You can now remove the battery lifting it up diagonally and once the compartment is empty, just slide the new battery inside.

Make sure you align it with the projections at the edge of the battery compartment. Until you hear the switch click lower down the battery to the lock position. Now just let the battery charge up by plugging the AC adapter into the power outlet. It is advised to let the battery charge fully and only afterwards use the laptop. Don’t use it while it is charging. This goes on the way as well, if it is possible, it does help maintain a longer life in the future. Also, to benefit of such, you can also unplug any of the devices you are not using anymore, adjust the brightness if you are in a bright environment or outside the house and see the Power Management options to save some power. The battery life also depends on the type of usage of your system, if you manage intensive applications, video streaming and so, then it is normal to drain faster

Now that you have fully charged your new battery, you can enjoy longer time on your Sony Vaio laptop, just like in the beginning.

Dell Laptop Coupons

Considering buying a new Dell laptop? Before you add your desired product in the shopping list, try to see if there aren’t any Dell laptop coupons available, so you get some free discounts, shipping perhaps and you get to save up to 20% on the laptop you want. You can easily manage this by visiting Dell’s main website and scroll your mouse on the yellow bar on top of the website. Afterwards, a list with available coupons will show up and you have chances of finding a great deal. There are a lot of Dell laptop coupons on Inspiron series, Latitude and XPS. You can also get these coupons on other websites, as they are codes actually you enter, but the variety is not as large as on the company’s official website.

For example, there is a coupon code that applies to Dell XPS 17 laptops priced for at least $1600 and you get to save $200 off the price. For other XPS 17 laptops you choose below the mentioned value, you can save $75. Think that you can do something else with the money and they come back to your pocket. You can buy a good carrying case to carry your system better, perhaps an external mouse if you need one, a pair of speakers, cooling pad and so on. There are many laptop accessories you will need afterwards and you can use your initial sum of money to cover the system and a chosen product at once and no extra payment afterwards. The same goes for the Inspiron laptops, you get $50 off for Inspiron 14R, $70 off Inspiron 17R laptops or 25% off any laptop you choose. You can enter one coupon code, so choose the one that has the greater value and the one that will suit the product you are buying. Why not save some money if the company provides it?

All you need to do is copy the coupon code from the page of the website and apply it when you checkout the product. After the application, you will see the instant savings you do. If you have other laptop in mind, then you can go on other websites and select other coupon codes to copy and paste, as they are spread around the internet. Dell is one of the most reliable and respected company when it comes to computers and accessories, so if you have chosen it, you will not regret it. The variety of laptops offered is great: everyday tasking, performance, business, gaming, tablets, mini laptops and so on. Whatever you need the company has it and the best part is that you can now choose the colors you want on some of the portable systems, thus personalizing them and making them on your liking.

And that is about all you need to know about Dell laptop coupons and how to apply them, what and how much you save. Without doubt, it is a good deal and the company sure knows how to sell its products. There is nothing better than getting something cheaper than initially, putting some money aside or just having some extra pocket money for later on. You will need to take your laptop outside and show it off, so why not get your friends over a coffee and show them your new system with the savings you make?

Dark Fairy Laptop Skins

If you take a look at how laptops look these days, especially the ones from Dell and HP, with great designs and patterns on the chassis, you just consider changing your own system, even though you are satisfied with everything except design. But this should not be the case, because there are alternatives of changing the looks of your laptop, perhaps covering some scratches and nasty marks, make your kid happy and “draw” the laptop he/she has, make your girlfriend a present by giving her something personalized. You can manage all these with some nice laptop skins. And when it comes to having something on them, an image or so, there is nothing that can’t be placed on it. You can even find dark fairy laptop skins and you can shop online from retail stores, or choose the specialized shops with skins for any laptop model or size.

The price depends on the place you buy the skins from and if you find the skin already customized, then you don’t have to pay a lot of money, just around $20, but if you want a special dark fairy on your system, then the sum goes a bit higher. What is more, skins are designed from vinyl and you can easily place them on your system, just like stickers and also remove them easily, without the nasty goo marks or glue leftovers. The adhesive backing is durable and some use different types of glue, so you can check and see if the skin you chose doesn’t have the one from 3M, as it is a higher quality one. As you will be buying skins according to the laptop you have, size and model, it will fit perfectly in the end and you will enjoy a brand new look. Even you will start thinking that you changed your laptop. Some of the skins don’t cover only the outside, but the inside as well, as they go all around the display and up to the touch pad, covering every surface. When you need to change the skin and put another dark fairy laptop skin, just take the old one off and stick the new one. You can remove and reuse skins along the way.

There are a lot of options to personalize your laptop computer and among the most popular ones and the cheapest is this one: using skins. Get the colored ones and bring your laptop up to life, even if it has that dull, black or silver design. But check to see how the skin will fit your laptop if the skin is more transparent or compact. The colors can change due to the chassis and the image on the skins. Nevertheless, you can read about the return policies of the company and see if you can’t return the skin for another one in case you are not satisfied with the product you bought. Why wouldn’t you buy some laptop skins as they are so cheap? In case you didn’t know, there are skins for everything: walls, cars, mobile phones, printers, MP3 players, iPads, digital cameras and a lot of other gadgets. This means you can personalize any device you have and change everything about their style.

As everything is at your disposal online, you can browse through the websites with skins and see more on the descriptions area.

about old computer

I just read an article on the many uses of old computers. The best ideas seemed to be ways to allow your computer to be used by others over the net. One obvious use is to let the old computer serve up torrent files. Even a lanky old Pentium came server this purpose.

Another noble use for your old PC is to have is join the TOR network. This essentially allows users to hide their location and identity. It makes it harder for somebody to track their internet traffic. The goal of this system is to provide personal freedom. The software is open source. It is good for IRC, Instant Messaging, and web browsing.

Finally you can install the BOINC client on your computer. It lets you choose worthy projects for your computer to work on during idle processing. For example, you can help the search for extra terrestials by choosing the SETI project. If your old computer has a graphics processing unit (GPU), it will help the effort even more. Now there is no need to junk that old PC. Put it to good use.

rainbow keyboard of computer

Is that drab old monochromatic keyboard getting you down? This keyboard from Korea’s Luxeed features color changing LEDs under each and every key.

While it can certainly be used to produce seizure-inducing displays of blinking color, the keyboard comes with software that lets you do more subtle things, like just set the keyboard to a light up with a single hue that strikes your mood, or create intricate patterns of color.

Luxeed’s USB keyboards are available in a white backlit version (KRW 118,800 / $127 USD) and a sleek black backlit version (KRW 125,600 / $134 USD), where the keys stay black and only the letters change colors.

The keyboards have started to trickle out in their native land of Korea, but hopefully somebody will see fit to import these into the U.S. and Europe

about video game

A video game is an electronic games that involves interaction with a user interface to generate visual feedback on a video device. The word video in video gametraditionally referred to a raster display device, but following popularization of the term "video game", it now implies any type of display device. The electronic systems used to play video games are known as platforms; examples of these are personal computers and video game consoles. These platforms range from large mainframe computers to small handheld devices. Specialized video games such as arcade games, while previously common, have gradually declined in use.

The input device used to manipulate video games is called a game controller, and varies across platforms. For example, a controller might consist of only a button and a joystick, while another may feature a dozen buttons and one or more joysticks. Early personal computer games often needed a keyboard for gameplay, or more commonly, required the user to buy a separate joystick with at least one button.Many modern computer games allow or require the player to use a keyboard and a mouse simultaneously.

Video games typically use additional means of providing interactivity and information to the player. Audio is almost universal, using sound reproduction devices, such as speakers and headphones. Other feedback may come via haptic peripherals, such as vibration or force feedback, with vibration sometimes used to simulate force feedback.

The Birth of the Personal Computer

Forty years ago this week, at a conference hall in San Francisco, a Stanford computer researcher demonstrated the first personal computer.  The device had a mouse and monitor, and featured rudimentary tools which enabled moving among documents, as well as text and graphics editing ability.

The scientist who headed the development team envisioned a computer that would assist the average office worker with everyday tasks.  However, as it required 500 single key commands, the device never made it out of the lab.  But many of those involved contributed to later projects which led to the PC revolution and the Internet.
