Laptop motherboard maintenance methods

Feb. 20, 2011 - PRLog -- Laptop motherboard maintenance methods
First the dimensions of the main plate repairing the original is first Jane after numerous, soft hard, after the first local specific to one of the first after components.
Not to work for the Laptop motherboard son points of two kinds: it is not have used, it is just playing out to won't work, often occur in WS and ES stage that the son is concerned, the Laptop motherboard WS
Still need to be in open machine before moving into a series of unascertained listed do work, such as measuring confess than power to the earth of electricity resistance etc, in this was not accurately described. Another kind is is my were made by cheng causes
Don't open the board, don't tube machine in a factory professionals of measuring tried process also is in the family use in this affection condition, but also very often see this article will explain the key.
The Laptop motherboard maintenance methods:
1. advisory board in the Lord with door asking out now before the shape with fault condition and the work of the state? What are the original advisory asked for caused by fault? Advisory asked Lord plate work in what fault
Environment, etc.
2. sked that ever used this piece of Laptop motherboard to bottom in what department for what does exercise a with the result of not switch on after you see this after a asked questions of where,
Use mesh measurement method observation on the mainboard of electric capacity is no have bulge, discharge or strict heavy damage, is no have been charred core slice and electrical components, the son is no where short circuit, and less electricity son yuan implement
Pieces or PCB disconnection etc. Still each slots have no clear show damage.
3. the smell is listening, mending the Lord the plate is watching, and hope to be not with the levites, look with DEBUG card ran out of the number; Don't have to pay attention, DEBUG
Card ran out of the digital not completely without by accident, it only can regard a a reference; For example, in 38 DEBUG card run columns table is "shadow system BIOS ROM" but is practical
Only is a piece of the RAM 32PIN + A3 empty welding (I'm KM22 bolt machines on unascertained have known, will be the first one piece 32PIN - the first RAM is the 13th to address the third - cock),
DEBUG card also run 38.
4.no not is by hand, and is used in table and oscilloscope, 000 with million in table Lord will is to measure electric pressure and resistance, with an oscilloscope can never failed to solution sequence on the topic. Ask
Electric resistance measurement method: also called on to measure resistance value method. Can use the measurement method to the size of Yin value core piece broken cause sentenced to large and electric son yuan implement pieces of good or bad, and sentenced to broken electricity road strict heavy short
Road and continuity. Such as: using diode gear measurement crystal body pipe is no have strict heavy short-circuit, broken road conditions will judge cut its good or bad, or to the ISA slot on the resistance value will judge broken occurrence
Good bad situation, etc.
Electric pressure measurement: the Lord had measuring electric pressure if tong, but after the Lord with is often measured than a pilot board, to find out some differences in the pilot, the most after the measurement of the line (test pilot along the road runs electricity)
Finally find out a fault element, replacement components.
Through the above steps, I have too few in the amount of hand work can be finished by welding take into.
