The key parts of the notebook motherboard test voltage
Notebook motherboard (also known as "substrate") in terms of function or structure on, the desktop has a considerable degree of difference. We can use the network to download on Inter Dragon motherboard chip schematic Perhaps my browser, then those are the original circuit diagram Inter.。 For us, whether desktop or notebook motherboard motherboard, in the analysis of alignments are very useful.
However, the notebook's motherboard circuitry, there will be no desktop motherboard circuit to then "open", and my analysis may be regarded as the notebook is not a popular thing, the manufacturer of this technology, now also do not want to open.
：SIS 630） Since many notebook brands, even if the models are similar to the configuration of the motherboard except on South Bridge, North Bridge (or the integration of North and South Bridges, and a chip, such as: SIS 630), like other chip components, have different There is no pattern appears. Extreme lack of information, which give us the repair with a considerable obstacles. However, there is some parts on the notebook, and its normal job of the voltage, basically there is a certain degree of regularity. Following on the list on a notebook motherboard voltage of several key data.
The general power supply motherboard components (V) and a special note
1- CPU power are MMX-P4-voltage 1.5-2.8V specific manual, please visit Inter
2-hard drives are 2.5 inches Power Supply 5V, 1.8 inch is the dual voltage is 3.3V and 5V
3- SD are 3.3V, DDR memory is 2.5V
4 -shows the on-screen signal IC are 3.3 power supply, voltage range of other data
5 -shows the high voltage to high voltage power supply board are ranging from 5-15V
6- single-chip brands, different functions, are the early 5V, mainly 2.5-3.3V
7-graphics cards are the early 3.3V, the minimum is 2.5V, there is some GF4 are 1.8V
8 -PC 3.3 5V 8 PC Card 3.3 and 5V
9 -keyboard controller 3.3, either in single-chip with integrated
10-sound card 3.3V
After watching some friends certainly have a question? ？ The above is referring to itmotherboard? Voltage test point at what exact location?
！ Stresses are also too general it! ，In fact, I mentioned the one on the start, unlike the desktop notebooks, too many changes, but above the test voltage, each block has notebook motherboard, but you have to be specific to the maintenance of the board, it may be there a little bit of small change, this is a go yourself to rely on experience and experience go slowly.
