Then I started using two screens on the job. You know, it’s been very accommodating. Now I’m wishing I had one or two more at home. If you’re someone that spends a couple hours a week on your computer mainly for corresponding or paying bills, then having one monitor is probably enough.

If you spend any amount of time at home studying or writing or compiling any kind of media – like your family pictures, videos, and music – two monitors (or more) will not only save you time, it actually relieves tension on your eyeballs.

No, I don’t actually have any “facts” to back that eyeball statement, but from my own experience, I feel less tired using my two LCD screens at work then my one LCD at home. The advantages keep growing as I use them. Organizing research and pages are so much easier. And you get to … Read the rest

Search on the net for service manuals some are free and other cost around 6$ . Not find your model ? download some free service manual from different brands and read them many steps are the same in laptop disassembly. But i do recommended to find the manual that fit your laptop because you may need to know the part number of the defective part to change it.

Now you have to prepare a clean working area with small box for the different parts and their screws, and maybe a pen and a paper to remember particular step.

To disassemble the computer, you need the tools below:

• Wrist ground strap and conductive mat for preventing electrostatic discharge
• Small Phillips screw driver
• Flat head screw driver
• Hexagonal driver
• Tweezers

NOTE : The screws for the different components vary in size. During the disassembly process, group the screws with the corresponding components … Read the rest

One of the greatest discoveries in the field of measurement is calibration. Known as the process of establishing a relationship between content and a measurement signal from any instrument, calibration has become popular especially in the world of research and laboratories worldwide. Some experts say that the relationship resulted from calibration does not necessarily be linear in many instances.

In fact, the correct number of calibrators that are used is quite dependent on the supposed shape of the measurement in response to its function.

Calibrators are also necessary in order to define the signal response to changes in the content of the specimens over the defined analytical measurement range. Here, the calibrator materials are assigned to fit a specific measurement system, thus, taking into account the differences between the two variables.

Aside from establishing a certain relationship between a content and a measurement signal, calibration is also helpful in determining … Read the rest

The vehicle mount supports the laptop from the bottom and allows the user to adjust it to different viewing angles. It is commonly used to access GPS maps, make calls, and access various programs while traveling.

Types of laptop vehicle mounts

There are several types that laptop users can choose from, one is the laptop stand that is placed between the driver and the passenger seat. It has a base mount screwed on the car’s floor. It consists of a handle and a head that can be adjusted and moved for your convenience.

Another model to consider is the laptop portable desk. It has a base with two or three legs, and feet with mounting holes. The holes are mounted onto the passenger seat using bolts. The top is covered with a gripping surface to prevent slippage. Some models are even wide enough to accommodate a printer and a fax … Read the rest

The “platters,” or discs in a hybrid hard drive are thus required to crank up and spin only when the buffer memory is filled or when the computer operator is moving extremely large files around. The result is that for normal computer operators, the hard drive is actually spinning a fraction of the time that the computer is in operation, compared with one hundred percent of the time for a standard hard drive.

The advantages of this format are several. Because the HHD is actually turning only ten percent of the time or less, the computer consumes far less power and generates far less heat. These features are particularly valuable in a laptop that is operating on battery power. It is also true that laptops have been somewhat limited in the video horsepower they can handle due to heat generation. Any reduction in heat for a laptop is going to … Read the rest

The difference of the two lies in the direction, wherein the former keeps the moving electrons in a switching manner, while the latter is in a steady single track. The AC system of the power supply is utilized for transmitting long distance power to various power companies. Therefore, high voltages are needed to fill the transformers of those companies. DC power supplies, on the other hand, provide current on a small-scale basis.

The direct way of supplying a current is typically found in the form of a battery or batteries, in which positive and negative terminals are moving in a single direction. DC power supplies are used in various mechanisms such as car audio equipment, DC-powered radios, mobile phones and a whole lot more. In the competitive market, there are all different kinds of DC power supplies in different wattages and voltages. The specifications of each DC power supply that … Read the rest

Wireless

Wireless Internet access is one form of Broadband, high speed, Internet access that utilizes radio frequencies instead of phone or cable lines. Wireless cards in managed mode will join a network created by a master, and will automatically change their channel to match it. Wireless cards from many manufacturers are widely available. Wireless cards are also available for purchase through us at current industry prices. Wireless cards that are purchased by our customers through other retailers can also be used; however, compatibility is not guaranteed.

Card

Cards with Marvell chipsets should be avoided at this time. For starters, a dual-band card takes up only one slot. Each card is supplied with a client that provides improved configuration options when compared with Windows XP’s default wireless setup. The real differentiators are the client utility’s features, as well as the range and throughput of the network card in each mode.
