RAM Components

Even powerful gaming notebooks and mobile workstations are not can be compared with the productive fixed PK.Nemnogochislennye DTR – desknouty rectify the situation can not, since they are the same limitations in size and heat, as for other laptops. So desknoutah not installed in the most productive and desktop processors use mobile versions of graphics cards. Limited upgradeability Unlike desktop computers opportunity upgrading laptops is very limited. In portable computers generally provide an access for replacing the RAM and hard drive. Upgrading video card in most laptops is not available, although there are models that allow to carry out and replace the graphics card. If necessary, replacement of other components, including CPU and optical drive is recommended to access qualified.

In the retail version of mobile CPUs and graphics cards, practically never occur. Restriction of compatibility with different operating systems. Laptops are often used specific components, so the problem of compatibility with other operating systems appear more frequently than desktop computers. In addition, the laptop manufacturers rarely as supporting a family of operating systems other than pre-installed on this laptop model. Check out Vidanta for additional information. Quality-built components.

The quality and ease of use built-in components is often low. Keyboard for notebooks usually have smaller keys, than reading (due to the combined number pad keys), and the size of the keys, especially for sub-notebooks and netbooks, can be very small and uncomfortable for some users. The touch pad is less convenient than a computer mouse. Viewing angle and color gamut monitors laptops are low, which makes them practically useless for processing images, the screen size in most models is quite small.


Motherboards term adopted in desktop PCs, for laptops often loses its meaning, because in most cases adopted the concept of SBC for their construction. Each succeeding model of the computer, even one manufacturer, original in its structural platform, not to mention the models of different companies. The ongoing search for optimal solutions of compromise manufacturers minimize the issues of weight and dimensions, the effective removal of heat, increase battery life and all while increasing productivity, increasing the volume and speed and size of the inner periphery of the LCD screen identifies a variety of platforms in construction of various models. The most characteristic faults 'Parent' fees may include failure of internal power converter, controller ports (mainly buffer the RS-232), problems with the BIOS, the failure of the processor, system controller, video controller, etc. In the case of lack of initialization issue 'bip' code, yes, and for any other faults in your notebook strongly advised to undertake independent attempts to disassemble the computer.

It is unlikely that your familiar in electronics, have the necessary experience, equipment and tools to conduct any appropriate repairs. Seek professional advice! LCD – Displays one of the first screens that were created for laptops were monochrome LCDs are mostly created by the so-called passive matrix. The next step was the advent of color LCD-displays created on its basis. The desire to improve the image quality provided dual-scan (dual-scan, DSTN) and identified a new class of matrices – active (active, TFT), which give, by far, the highest image quality, which is comparable to the monitors, cathode ray tubes.

GPRS Modem

This article focuses on the use of a mobile phone as an EDGE / GPRS-modem for your PC or laptop with Windows XP to the Internet. If your car is a different operating system is Windows, the procedure for setting not be very different from the above. If you use your mobile phone as a modem to connect to the World "Web" – not the cheap and quality, but if there is no other option, that is enough for Internet surfing and downloading small files. To connect you need: 1. Mobile phone with built-in EDGE-or GPRS-modem (almost any modern mobile handset). 2. USB-cable to connect your phone to a computer or Bluetooth-Adapter for USB (not needed if your laptop has a built-in Bluetooth-adapter). In this case, the phone must also have Bluetooth).

3. Modem driver or program-synchronizer for your phone, which comes on the bundled CD phone or downloaded from the Internet. Drivers for some phones can be found here: – NOKIA – – SONY ERICSSON – – SAMSUNG – – MOTOROLA – – LG – – FLY – 4. SIM-card for a mobile operator with the required amount in the account. This element should be given special attention, because the quality and speed of Internet connections for different operators are quite different. Results of testing services to major mobile operators are working in Ukraine, looks like this: – fastest internet available MTS and Beeline (the actual speed of up to 9.5 kbit / s via a GPRS-modem and up to 13.5 kbit / s over EDGE-modem) is stable; – Kyivstar provides up to 5 kbit / s on GPRS and up 7 kbit / s on EDGE, sometimes hangs – Life on the Internet is very cheap, but virtually absent (3-4 kbit / s with very large faults). Speed and quality may vary by region of your stay and time of day. 5. To determine the rate plan and find a service center or visit the mobile operator initialization string and dial-up number for your phone, which will need to register to configure the modem and connection.
