look for bad caps, bestec power supply's fail a lot

Hopefully nowhere, that's a cheap unreliable psu, don't use such brands.

I repair power supplies and various electroics, most cases it will be compacitors, or diodes which have caused it to fail!!

go to dell web site then to support then type in board some do have autodect ok

Not worth the trouble. By the time you locate the bad part, find a replacement put it all back together and hope nothing else goes bad, you have the price of a new one.

Most are plug and play. I would assume your battery chargers need higher voltage to charge.

Put a wire between green and black wire

Sounds like the MotherBoard is dead?

You might want to post this question in a different section. This is the computer psu section.

This is an easy fix so here you go nice and simple:

Problem: Your motherboard circuit has been cut.

Causes: Power disconnected during operation. Power outage or short in the surge protector.

Symptoms: Flashing green light on both motherboard and power supply. System will not power on.

Solution:

Step 1: Ensure that both the power supply and the motherboard lights are flashing green, not solid or off.
Step 2: While the power is on, disconnect the power supply from the motherboard. This connection is the largest of the connections and should be listed as the 'P1' or 'Primary' power connection.

Step 3: Wait until the green light on the motherboard stops flashing and check to ensure that the green light on the power supply is now solid. If it is not solid, disconnect the power to the power supply and wait until the light turns off completely. Then reconnect, it should be solid now.

Step 4: While the power is on, reconnect the P1 connection to the motherboard and you should now see that the light on the motherboard is solid.

Step 5: Power on your PC. The problem should not persist.

Warnings: If the power supply light remains flashing after you have restored power to it while it is disconnected from the motherboard, it may be a system failure in the power supply itself requiring replacement. Always be careful when working with an active or live power machine.

I hope this helped! Good luck!
