My dell inspiron 8200 has had trouble with power issues - usually with the
a/c jack connection coming loose and loosing the ability to power the unit.
by the time i got the motherboard replaced, it had also stopped charging the
batteries when plugged in.

With the new board, the a/c jack works fine, and i can run the computer, but
the batteries still won't charge. when i run the Bios Update (to A011), and
the Dell Diagnostics program, it recognizes the batteries and says the
charging feature is "OK".

The batteries are both good, as have been both bays in the past.

Also, the system seems to think that the a/c power converter (power
supply/brick) is a 70W unit, when it's actually a 90W unit. It did this
toward the end of the first board's life, and it's still doing it. It gives
me that error on any power supply i use with the system - i have tried 3,
all of which were known to be good.

No professional i've taken this to has been able to fathom anything past "it
must be a board problem" - but it's NOT. the new one i got is Fine. what
else could it be?

Thanks so much for your help.

Bob:

The 90W power AC Adapter utilizes the third pin in the connector where
as the 70W unit doesn't. To trouble shoout the problem, you will need to
make sure that the AC Adapter has output in the third pin. If it does,
you will need to check the connection on the motherboard. If you have
already verified the AC Adapters on other system, chances are that the
pin/connection on your motherboard is the problem. I hope you didn't
have to pay the "Professionals" for the incomplete Diag.

no, i did most of the work myself.

as far as i can tell, all 3 pins are being used/connected. there are no bent
pins or receptors. thanks for the tip - i didn't know the difference
between 90W and 70W. but that doesn't appear to be it.

So. Did you measure the Voltage on the MB with a Multimeter to check for
the AC Adapter's input to the MB? Have you trace the Power Input?

no, in fact, i doubt i capable of that. it's a good idea, though. why would it be reading lower than 70W? could there be a ground or bleed somewhere?

thanks agian for checking in - i really appreciate the advice.
