Question about E-Machines Bestec ATX-300-12E Rev. D 300w E-Machine GTW Power Supply Part 100929 (ATX30012E) Power Supply
A friend gave me a chance to try to fix their emachines w3507 power problem. they had a storm one night. woke up the next morning and the computer was off. I tried all the obvious troubleshooting techniques first (i.e., monitor, power outlet, etc....). I even tried holding power button down for a second for a power offload. There was a dull blinking orangeish indicator light on the front of the tower "ePower Button". Inside the tower, a tiny light green LED above a circuit labled "SPDIF 1" or something on the board was blinking. ---- I know the hard drive is fine because I took it out, put in another computer and it booted up fine. I tried putting another computer's good power supply unit in defective tower, and the only changes I noticed was that the tiny light green LED on the board went from blinking to solid and so did the orangeish light on the front. I put original power supply back in defective tower and both LED's are continuing to stay solid. In both power supply configurations named above, there was no fan or other indications of power other than the mentioned LED's. Does this mean that it's probably the motherboard, the power supply unit, or both?? Please give me whatever useful(or not) input you may have on this......absolutely anything will help and be greatly appreciated.
Detarch all accessories or hardware connected to the system , then bring out the power pack itself out completely look for a soldering led to test the functionality of the power pack itself if it rotates the fan of its pack by looping the first hole to the third hole cable in the power pack connector that will head into the motherboard. therefore, check the mother board if there is any damage on it like some component if all this is false . then plug the power pack to the outlet and fix the connector of the power pack to the motherboard after detaching both cd drive , floopy disk drive leaving the hard disk and the memory . then change the memory card and press on the system there should be a solution from all this . the problem should be from the Memory not to be able to start up the system but go through those process i have given you before concluding it was the memory ok....
kindly rate this solution......
