Many fans of their laptops often hear the phrase in the service: "Northern Bridge is defective." Urgent repairs are needed." Is this a verdict or can the system be made?" Let's try to figure it out. Of course, for many such a breakdown sounds ominous. Don't get desperate right away. First, you need to see what caused such a nuisance, and you need to find ways to eliminate it. It is important to know how this system works. Then it will be possible to avoid breakdown. You do not need to disassemble the laptop, especially, to carry out diagnostic work, if you understand how to avoid trouble. This is available to any user.
What is the northern bridge?
In fact, the north bridge is just a small chip that acts as a controller. It seems that everything is simple, but there are situations when the motherboard has to be changed precisely because of this detail. What role does this mechanism play? The answer is simple enough. This binder between the processor and the rampig card and the graphics card. It turns out that it connects the most high-speed mechanisms. These elements accumulate heat. And where there is a lot of it, a constant withdrawal from the system is required. Regular air circulation is required.
How do I determine that the northern bridge is faulty?
How do I determine that the northern bridge is faulty? This issue is of concern to many users. Those who have encountered this problem know that if the northern bridge is not functioning, it means that the laptop in most cases broke down completely. Many specialists do not undertake to replace this chip, as the repair does not meet expectations. Repair of the northern bridge is comparable to the purchase of new equipment. The problem is still finding the chip itself. It's hard to find the right model. So how do you identify the fault of the north bridge? The main sign of failure is the following: when the computer lights up the LED, nothing is loaded. It's probably a malfunction of the south bridge. If there are sounds, there is information on the screen, so the part is still working.
What should be done to avoid problems?
It has already been written above that the laptop accumulates a lot of thermal energy, so you should protect the system from overheating. The north bridge binds the elements, there is constant heating. What do you need to do to put everything in its place? This will require a state-of-the-game cooling system. It will use normal air circulation.
The difference between the south bridge and the northern
In the laptop, in addition to the northern bridge, there is a southern bridge. Both are controllers of equipment on the motherboard. The difference between the southern bridge and the north is this: the first one works at lower frequencies, respectively, the heat supply is less. Therefore, it is often not equipped with a radiator.
Thus, in order not to have future problems with the northern bridge, it is necessary to maintain the cooling system. This will require cleaning coolers, replacing the thermopath on the cooling system, on the northern bridge, on the video card. Check the temperature with special programs.
