Thinkpad Edge E520 no charge or power up

I have four Thinkpad Edge E520 laptops that don't indicate power from the powr supply or power on at all. I tried using the battery from a machine that does work and testing the power supplies on other machines that work, but none of the four problem children power up at all. I've removed all of the perihperals but no power or boot up. Also removed the battery with only external power and then tried to boot. Tried only with the battery and no boot. I checked the power supplies with a volt meter and they are a steady 20.33VDC. The charge indicator light on the side near the charging jack does not light up at all. Is it a fault of the charging board or the motherboard?


Anyone know of have the same problem that has been fixed?
