在一些主板介绍上，经常会看到MOS管这个词汇。究竟MOS管是 什么东西？它在主板上起到什么作用呢？

MOS管又可以被简写成MOSFET，它的英文全称是叫做：Me tal Oxide Semiconductor Field Effect Transistor[名词]。

翻译成中文就是金属氧化物半导体型场效应管。

MOS管为处理器等部件提供稳定的电压

MOS管是提供主板稳定供电的关键元器件。它是由金属，氧化物及 半导体三种材料制成的器件。它的主要作用是为主板上例如处理器、 内存或是PCI-E显卡提供稳定的电压。

由于MOS管在工作时，会产生大量的热量，如果MOS管品质不合 格的话，就容易因为长时间的高温，加上主板上的瞬间电流很容易会 把它击穿，从而造成无法开机的情况。因此如何将MOS管表面的温 度降低是各大厂家亟待解决的问题。目前，一些主板会选用低内阻的 MOS管以减少功耗，同时配合Drmos技术，将其控制在一个比 较低的工作温度，以保证使用寿命。

Repair 19 inch LCD monitor. All edges are nice and clean no scratch. Client is happy and he does not need to bring it to Shamshuipo. Note: the client has brought his LCD to shamshuipo once and 2 components has been replaced but we found that the LCD is on and off due to bad power regulator and it is self protecting and shutdowning it's operation. We replaced the new high voltage power board and new controller board. All materials returned to client and we re-connect LCD for client and do domonstration in front of client with proper instruction for durable usage.

computer motherboard repair services and we work with oscilliscope

1. need to use multimeter and false loading to check out core voltage, clock, reference voltage, address and data lines,
2. need to check out the clock in the MOS
3. need to check out the proper voltage in IDE port, mouse port keyboard port...etc.
4. BIOS must be correct....
