Intermittent in electronic repair definition means sometimes
equipment will work and sometimes not . Intermittent problems can occur
in any conductor and in every electronic circuit . If you found error (
for example , sometimes display sometimes not ) Laptop work properly
throughout the day without any problems and can last for a day and
did not have a chance to see the error .
However , sometimes the laptop does not work at all .
First think to do is updating Bios by executed new revision of Bios.exe .ensure adapter and battery in use when updating Bios.
Intermittent problems big possibility caused by dry joint , broken tracks , loose connection / cracked/ bad conductor area ~ Bad components / crashes and etc. .
This is a problem that has led to many electronic repairers become frustrated and if it does not have a better way to solve the problem and may be losing valuable time .
Observing for each solder connection to all circuit ' . Looking for some small cracks around the solder pad. If you can not see the dry joints , Power On motherboard and gently tapped the motherboard ( or suspected area ) with the handle of a screwdriver .Usually, the line circuit / track will not break by itself , Moreover, since the intense price competition , Laptop motherboard made thinner with less conductor material to reduce the cost of production . Problems can arise when the chips repair ( reballing / replacement) .
Broken circuit track and obvious dry joint during reballing process could be happen when we use unstandard BGA tools . This could be due to overheating , unpresition center board , bad flux or errors in the method of repair / desoldering chips .Decayed glue ( glue decay )Decay glue can conduct electricity , it has the ability to create an intermittent problem in electronic circuits , shorting of components that are located close to the glue that rot . For information , I have seen the glue that lies rotting under BGA chip and could not removed . We can not see the glue rot from the top and should pull BGA off from circuit to check.Splash of acid -containing beverages ( soft drinks or coffee ) to the electronic circuits . can lead to complete failure in electronic circuits besides error can intermittent.damage the components and pathways ( conduction ) . although it can be cleaned with the of Thinner , the circuit will be unstable and cause problems including intermittent fault .Each component : Integrated circuit (IC) resistor, Semiconductors ,inductors, Capacitors , Crystals etc can cause intermittent problems in electronic circuits if not properly etched . This can cause damage to fully or sometimes works and sometimes does not .
Easy way to make whole motherboard component properly etched,heats up to the boiling point of lead using Oven .Cooking oven will be an alternate if you don't have special electronic circuit oven.

got excellent ideas thanks
