| Macbooks Mean Quality- Get Great Deals! Posted: 29 Mar 2011 05:49 PM PDT Macbooks Mean Quality- Get Great Deals! There’s no doubt in my mind that the new Apple Macbook is one of the best laptops in the market right now. Upon release, I began to scour the internet for some great cheap Macbook deals. I’ll first teach you how to spot one yourself. This applies to any thing that you may want to purchase online. Things to watchout for: 1) Is this product in stock? There are a lot of online dealers out there allowing you to buy the Macbook online but don’t tell you that they don’t have it stocked yet in their inventory, so it will actually take some time for you to order. Watch out for these people. How can you tell? Always look for an authorized dealer. Authorized dealers usually post the information regarding the number of items left in their inventory. If it is a very reputable online site, then it’s a safe bet that your future Macbook is ready for shipping. 2) Bonus deals One of the things people don’t know about is that, online dealers usually spice the item up in their online store (if they have a physical one) because they’re encouraging online orders! They have to give you a better deal otherwise they would be losing a sale to a physical store such as your local BestBuy. If you don’t get Bonus deals out of it, then you may be better off going to the nearest dealer and actually buy your Macbook there. 3) Rebates Ahhh Macbook cheap deals should have rebates! Mail-in rebates actually decrease the total cost of your Macbook. So instead of paying let’s say 00, after some time you get your 0 back. Again, if there are no rebates… go buy your Macbook somewhere else. 4) Financing Options A good deal offers a great financing option. Low interest payments per month, 0 payments for a certain period of time, all contribute to the overall Macbook cheap deal. The great thing about financing plans is that you really don’t have to spend a big chunk of your cash at one period of time. The idea here is to spread your costs over a relatively longer period of time. When you do this, you can be productive with your new Macbook, get some cash going, and actually pay for those small amounts over let’s say 6,12,18 months? Where to find all these? Each and every online store will have different features, different bonuses, etc. One factor to consider is buying from a very reputable website. I consider Macmall to be the best place to buy a Macbook. When I bought my Macbook I was only able to avail of the rebate but now the rebate is already at 0! What a great deal! Final Words The Apple Macbook is one of my best purchases yet. No viruses, no hassles, cool eyecandy, fast and reliable performance, all in one! All my pc-using friends have envied my Macbook for a lot of reasons among them of course is the design of the Macbook, simple, classy, and it doesn’t look like all the other laptops out there. Finally, it’s a joy to bring to work. I can type all day long and not feel any eye-strain, I can be sure that my Macbook won’t crash on me when I have a big project to do and here’s a big plus: It runs Windows. I can still play games with my friends and switch back to OS X when I want to work! If you’re still thinking twice about buying a Macbook. Don’t. Stop thinking and just buy it. You’ll never regret your purchase. Super tip: There’s a super tip you can take advantage of right now, I made a site/guide for free so you can purchase your Macbook with ease.

| Buy and Sell Desktop Computers Posted: 29 Mar 2011 03:47 PM PDT Buy and Sell Desktop Computers Desktop computers are always in high demand, with lots of households having at least one computer in their home. Many everyday transactions are handled online including banking, shopping and much more. There is no need to leave your home to do these if you don’t want to, as most aspects of your daily life can be dealt with online. However, this means that you require a computer. Many people prefer a desktop computer to a laptop as they are usually lower priced than a laptop. Purchasing a used computer is an option for anyone who finds the price of a new computer out of their reach. At Cash Generator, we also stock new desktop computers at a very low price, as well as used computers which are in excellent condition. It is also possible that you may want to purchase a higher specification model after a while, which is the ideal time to sell your old desktop computer and make some money to contribute towards the cost of your new one. Desktop computers are a valuable commodity that will sell for a good price in the second hand market, especially if you have taken good care of it and included all of the accessories. If you are particularly struggling to pay an unexpected bill or need some cash urgently, here at Cash Generator we have a buy-back facility which allows you to sell your desktop computer for a reasonable sum of money and then buy it back again within an agreed period of time, for a small fee for the service. When you initially decide to purchase a computer you have to decide whether to buy new or a refurbished computer. The main advantage of buying a refurbished or used desktop computer is the amount of money you will save. You can find many good deals in stores, although you should check a used computer carefully to ensure a genuine bargain. This is the main reason to trade with a reputable store. Before purchasing your chosen computer, check the casing and ports carefully for signs of physical damage, indicating that the computer has not been cared for and may have faults. Make sure that the computer comes with any CDs to install any programmes that you have been promised as part of the purchase. An important consideration before making your final purchase is the dimensions of your desktop computer. Consider whether the computer will fit on top or below your desk. It is also important to make sure any software included is legal and not copied, as you may have problems with software that isn’t genuine. Desktop computers make the ideal product to buy and sell, as the demand for a computer is always relatively high. Always buy from a reputable store, and retain all paperwork and instructions to make it easier to resell at a later date. As computers are valuable commodities they are useful if you want to raise capital in a hurry, whilst high demand makes selling easy.

| Posted: 29 Mar 2011 01:49 PM PDT 1) First steps (a) Unpacking When you unpack your iMac, ensure you hold it firmly by the sides. Place it on a nearby desk or working area where there’s a convenient electric socket. (b) Power cord Place the power cord through the hole in the back of the iMac’s stand and connect to the power port. Plug the other end of the cord into the electric socket. (c) Additional items Your iMac also comes with an Apple Keyboard, Apple Mighty Mouse and Apple Remote. Take the Apple Keyboard cable and connect to one of the USB ports on the back of the iMac Take the Apple Mighty Mouse cable and connect to a USB port on the side of the keyboard
If you have an Apple Wireless Keyboard and Wireless Mighty Mouse, refer to the wireless manual for their installation. (d) Internet cable Plug an Ethernet cable into the Ethernet port at the back of the iMac. Plug the other end of the cable into an appropriate modem or network. Please note: you also have the option of a wireless connection with Apple’s AirPort Extreme technology. (e) Basic features Before you switch on, note the basic built-in features of the iMac. These include: a microphone located on the top edge an iSight camera at the top of the screen together with a camera indicator light a slot-loading optical disc drive on the side of the iMac stereo speakers an infrared receiver two USB 2.0 ports on the Apple Keyboard
On the back of the iMac, there are also: three USB 2.0 ports an Ethernet port a Mini-DVI port an audio in/optical digital audio in port a headphone out/optical digital audio out port a FireWire 400 port a FireWire 800 port a power port
2) Initial set-up (a) Switching on and setting up Press the power button on the back of your iMac. Setup Assistant starts automatically. It guides you through all the basic procedures to create your user account email account internet connection
Setup Assistant also shows you how to transfer your files, applications and other data from an existing Mac computer. You don’t have to make these transfers immediately. Instead, use Migration Assistant (see Applications > Utilities) when you’re ready to bring the information across. (b) Customisation To customise your iMac, use Apple > System Preferences on the menu bar. This is the command centre for the majority of your iMac’s settings. (c) Sleep mode or turning off Putting your iMac into Sleep mode allows you to avoid the start-up procedure when you next use your machine. To implement Sleep, you have a number of choices: click Apple > Sleep on the Menu Bar press the power button and click Sleep in the dialogue box click Apple > System Preferences, then Energy Saver and set the timer on the Apple Remote, press and hold Play/Pause for three seconds
To wake your iMac, you have a choice of clicking the Apple Mighty Mouse pressing the power button pressing any Apple Keyboard button pressing any Apple Remote button
Use Sleep only if you intend to return to your iMac within a day or so. To shut down your iMac, either click Apple > Shut Down, or press the power button and click Shut Down in the dialogue box
To switch your iMac back on, press the power button. 3) Quick Mac OS X guide (a) Operating system Mac OS X Leopard is the operating system of your iMac (and all other Macs), and is already installed on your computer. It controls your files, applications and connected devices, and works in a similar way to Windows. (b) Basic controls As you’d expect, the basic controls are the Apple Keyboard and the Apple Mighty Mouse. If you’re more familiar with Windows, what you’ll find with Mac OS X is that you’ll need to use the keyboard and mouse fewer times to achieve the same results. (c) GUI The first thing you’ll notice with Mac OS X is the style of everything that appears on the screen. Mac employs a GUI (graphical user interface) called Aqua. This gives you impressive clean-cut images and stunning visual effects, all of which Apple has designed to make Mac OS X more user-friendly. (d) Central features The icons, layouts and navigation of the iMac screens are straightforward. There are windows, menus, folders and shortcuts. There are also four central features that help you remain organised and productive: Dock Finder Menu bar
Desktop The Desktop is a screen where you’ll normally begin each time you use your iMac. The first icon you’ll come across here (in the upper right corner) is the Macintosh HD (hard drive). When you use different functions of your iMac, other HD icons will appear. Double click on an HD icon to view the files and applications it contains. Points to note: Use the Desktop to store files, folders, pictures and documents When you connect an external device to the iMac, a corresponding icon appears on the Desktop If you create different users for your iMac, Mac OS X gives each one a separate Desktop The Desktop always lies behind any applications you’re running
Dock The Dock is a row of icons at the bottom of the screen. Use the Dock to access your most frequently used folders, applications and windows: simply click on the appropriate icon. You can customise the icons to suit your use of the iMac. Note that when a window appears, it has three buttons in the upper left corner. The red button closes the window The yellow button minimises the window to the Dock The green button maximises and minimises the size of the window
Finder One of the icons on the Dock is the Finder on the far left. Use this to navigate and manage almost every aspect of your iMac such as folders, drives and applications. Menu Bar There is only one Menu Bar with Mac OS X. It appears as a single line at the top of the screen. Use the Menu Bar to interact with a programme view and change settings and applications close applications view recent work log in or out begin the sleep mode commence a restart switch the iMac off
The Menu Bar alters according to the application you’re using. This way, it offers you the items most appropriate to the application. 4) Connectivity Your iMac has a total of five USB 2.0 ports (two on the keyboard; three on the back of the iMac). Use these to connect the Apple Mighty Mouse plus devices such as your iPhone iPod digital camera printer disc drive modem joystick
The ports will also accept USB 1.1 peripherals. Your iMac is pre-loaded with a large range of drivers. This means that it will usually recognise your USB device without the need to run additional software. 5) Extra features (a) Security Slot A Security Slot on the back of your iMac allows you to connect a cable and lock to deter and stop thieves. (b) Memory Access Your iMac has a standard 1 GB of memory. You can increase this by a further 3 GB by using the Memory Access slot at the bottom of the iMac. (c) AirPort Extreme wireless technology AirPort Extreme wireless technology allows you to connect to a wireless network. (d) Bluetooth® Your iMac has Bluetooth® 2.1+EDR wireless technology. This lets you connect wireless devices that include Bluetooth® mobile phones Printers PDAs The Apple Wireless Keyboard and Wireless Mighty Mouse

| Posted: 29 Mar 2011 09:49 AM PDT Computer Cooling Causes of heat build up The amount of heat generated by an integrated circuit (e.g., a CPU or GPU), the prime cause of heat build up in modern computers, is a function of the efficiency of its design, the technology used in its construction and the frequency and voltage at which it operates. The dust on the laptop CPU heat sink after three years of use has made the laptop unusable due to frequent thermal shutdowns. In operation, the temperature levels of a computer’s components will rise until the temperature gradient between the computer parts and their surroundings is such that the rate at which heat is lost to the surroundings is equal to the rate at which heat is being produced by the electronic component, and thus the temperature of the component reaches equilibrium. For reliable operation, the equilibrium temperature must be sufficiently low for the structure of the computer’s circuits to survive. Additionally, the normal operation of cooling methods can be hindered by other causes, such as: Dust acting as a thermal insulator and impeding airflow, thereby reducing heat sink and fan performance. Poor airflow including turbulence due to friction against impeding components, or improper orientation of fans, can reduce the amount of air flowing through a case and even create localised whirlpools of hot air in the case. Poor heat transfer due to a lack or poor application of thermal compounds. Damage prevention It is common practice to include thermal sensors in the design of certain computer parts, e.g. CPUs and GPUs, along with internal logic that shuts down the computer if reasonable bounds are exceeded. It is, however, unwise to rely on such preventative measures, as it is not universally implemented, and may not prevent repeated incidents from permanently damaging the integrated circuit. The design of an integrated circuit may also incorporate features to shut down parts of the circuit when it is idling, or to scale back the clock speed under low workloads or high temperatures, with the goal of reducing both power use and heat generation. System cooling Fan from Papst for racks. Air cooling Further information: Computer fan While any method used to move air around or to computer enclosures would count as air cooling, fans are by far the most commonly used implement for accomplishing that task. The term computer fan usually refers to fans attached to computer enclosures, but may also be intended to signify any other computer fan, such as a CPU fan, GPU fan, a chipset fan, PSU fan, HDD fan, or PCI slot fans. Common fan sizes include 40, 60, 80, 92, 120, and 140 mm. Recently, 200mm fans have begun to creep into the performance market, as well as even larger sizes such as 230 and 240mm. In desktops Typical airflow through a desktop ATX case. Desktop computers typically use one or more fans for heat management. Almost all desktop power supplies have at least one fan to exhaust air from the case. Most manufacturers recommend bringing cool, fresh air in at the bottom front of the case, and exhausting warm air from the top rear. If there is more air being forced into the system than being pumped out (due to an imbalance in the number of fans), this is referred to as a “positive” airflow, as the pressure inside the unit would be higher than outside. A balanced or neutral airflow is the most efficient[citation needed], although a slightly positive airflow results in less dust build up if dust filters are used. Negative pressure inside the case can create problems such as clogged optical drives due to sucking in air (and dust). In high density computing Data centers typically contain many racks of flat 1U servers. Air is drawn in at the front of the rack and exhausted at the rear. Because data centers typically contain such large numbers of computers and other power-consuming devices, they risk overheating of the various components if no additional measures are taken. Thus, extensive HVAC systems are used. Often a raised floor is used so the area under the floor may be used as a large plenum for cooled air and power cabling. Another way of accommodating large numbers of systems in a small space are blade chassis. In contrast to the horizontal orientation of flat servers, blade chassis are often oriented vertically. This vertical orientation facilitates convection. When the air is heated by the hot components, it tends to flow to the top on its own, creating a natural air flow along the boards. This stack effect can help to achieve the desired air flow and cooling. Some manufacturers expressly take advantage of this effect. In laptop computing Most laptops use air cooling in order to keep the CPU and other components within their operating temperature range. Because the air is fan forced through a small port, it can clog the fan and heatsinks with dust or be obstructed by objects placed near the port. This can cause overheating, and can be a cause of component failure in laptops. The severity of this problem varies with laptop design, its use and power dissipation. With recent reductions in CPU power dissipation, this problem can be anticipated to reduce in severity. Liquid submersion cooling An uncommon practice is to submerse the computer’s components in a thermally conductive liquid. Personal computers that are cooled in this manner do not generally require any fans or pumps, and may be cooled exclusively by passive heat exchange between the computer’s parts, the cooling fluid and the ambient air. Extreme density computers such as the Cray-2 may use additional radiators in order to facilitate heat exchange. The liquid used must have sufficiently low electrical conductivity in order for it not to interfere with the normal operation of the computer’s components. If the liquid is somewhat electrically conductive, it may be necessary to insulate certain parts of components susceptible to electromagnetic interference, such as the CPU. For these reasons, it is preferred that the liquid be dielectric. Liquids commonly used in this manner include various liquids invented and manufactured for this purpose by 3M, such as Fluorinert. Various oils, including but not limited to cooking, motor and silicone oils have all been successfully used for cooling personal computers. Evaporation can pose a problem, and the liquid may require either to be regularly refilled or sealed inside the computer’s enclosure. Liquid may also slowly seep into and damage components, particularly capacitors, causing an initially functional computer to fail after hours or days immersed. Waste heat reduction Where full-power, full-featured modern computers are not required, some companies opt to use less powerful computers or computers with fewer features. For example: in an office setting, the IT department may choose a thin client or a diskless workstation thus cutting out the heat-laden components such as hard drives and optical disks. These devices are also often powered with direct current from an external power supply brick which still wastes heat, but not inside the computer itself. The components used can greatly affect the power consumption and hence waste heat. A VIA EPIA motherboard with CPU typically generates approximately 25 watts of heat whereas a Pentium 4 motherboard typically generates around 140 watts. While the former has considerably less computing power, both types are adequate and responsive for tasks such as word processing and spreadsheets. Choosing a LCD monitor rather than a CRT can also reduce power consumption and excess room heat, as well as the added benefit of increasing available physical desk space. Conductive and radiative cooling Some laptop components, such as hard drives and optical drives, are commonly cooled by having them make contact with the computer’s frame, increasing the surface area which can radiate and otherwise exchange heat. Spot cooling In addition to system cooling, various individual components usually have their own cooling systems in place. Components which are individually cooled include, but are not limited to, the CPU, GPU and the Northbridge chip. Some cooling solutions employ one or more methods of cooling, and may also utilize logic and/or temperature sensors in order to vary the power used in active cooling components. Passive heat sink cooling Passive heatsink fitted on a Intel GMA graphics chip Passive heat sink cooling involves attaching a block of machined or extruded metal to the part that needs cooling. A thermal adhesive may be used, or more commonly for a personal computer CPU, a clamp is used to affix the heat sink right over the chip, with a thermal grease or pad spread between. This block usually has fins and ridges to increase its surface area. The heat conductivity of metal is much better than that of air, and its ability to radiate heat is better than that of the component part it is protecting (usually an integrated circuit or CPU). Until recently, fan cooled aluminium heat sinks were the norm for desktop computers. Today many heat sinks feature copper base-plates or are entirely made of copper, and mount fans of considerable size and power. Heat sinks tend to get less effective with time due to the build up of dust between their metal fins, which reduces the efficiency with which the heat sink transfers heat to the ambient air. Dust build up can be countered with a gas duster by blowing away the dust along with any other unwanted excess material. Passive | ||||||||||||||
