Caution: I drew the diagrams from the boards so there will be some Errors.
I have a question for you ATX Experts.
What is the Small winding on the Driver transformer for?
I Like the cheepo way they got the 3.3volts, It puts a big load on the 5v supply.
So, the Supply is only $25 new on EBAY.
The 1000uf filter Cap. C15 on the 5volts keeps going bad.
One board is 2 years newer and they changed Supervisor Chip.
Interesting fact: When C15 was going bad 200uf measured instead of 1000.
The symptom was: When I put the Computer to sleep It would lock or crash.
Worked fine the rest of the time. It would boot right back up OK.
