What is the North Bridge in a notebook: how it differs from the southern

A specialist in the service center after diagnosis of your computer's verdict: burned Northbridge. What is it - about the video card, network adapters, motherboards and other important stuff you've heard. But that's about the bridges have not had to... What to do and whether you need to worry much? Now we shall understand! In this article, we will focus on the purpose of such an important element, and maintaining it in working condition.

North Bridge in a laptop: what it is and how it differs from the southern

It is no secret that the most important element of any computer is the motherboard. It is composed of literally everything - from slots to power up the USB-connector, including the north and south bridges. By the latter is meant microcontrollers that control the periphery. In particular, for communication with the card processor and the main memory corresponds to north, and to communicate with network adapters and I / O devices requires the south.

Reference! Bridges operate at different frequencies (upper - in large, lower - for small). Hence the difference in the amount of heat they generate.

So Northbridge (as it is called in English literature) - one of the most essential parts of the device. Because of its proximity to a powerful electronic components, require serious cooling system (the bridge is always cooler or cooler installed).

The main functions of the northbridge are:

• processor start (switch);
• launch video;
• Control RAM;
• Recognition system bus parameters.

It turns out that the failure of (mostly combustion) of this chipset, further work is impossible with a laptop. In this case, when you turn on more often than not it comes on the screen. The following displays are possible: the computer is turned on only 5-10 times, can independently start rebooted or shut down, there is no reference to the RAM or to a hard disk (is distributed unpleasant sound).

How to extend the performance of Northbridge

The most logical solution to this problem will ensure that the laptop does not overheat. This means that you should try not to leave it in a state of switched on the bed, pillows, smaller work placing it on your lap. At the same time be sure to regularly organize routine inspections and cleaning of the cooling system.

once every six months is recommended to remove the back cover to:

• remove accumulated dust;
• clean the cooler;
• change the thermal paste on the CPU, graphics card and the north bridge.

Additionally overheating fail this element may due to physical damage or water droplets. It must be remembered that the bridge - it is a very fragile element.

What if the "diagnosis", which was mentioned earlier in this article, your device already issued? Immediately give it to a service center for professionals! Independently replace the desired item is not even worth trying. The chip in question, is soldered to the board of BGA technology. To replace the need easy availability of professional skills, but also a serious equipment.

Reference! Installation BGA provides shrinkage element on the board with the literally thousands of pads (solder balls).

If we stick to tips to extend the life of the chipset and use a laptop with due diligence, no replacement is not required, and it will work for many years without interruption. Now that you know all the most important element of the "north bridge" and prevent it from failure.
