Having problems with your Toshiba Satellite A75-S206 Notebook ?

Laptop only runs on battery even though p/s is plugged

\015 I have a Toshiba Satellite A75-S206 laptop that only runs on battery. It will not run on the A/C power supply even though the power supply does charge up the battery when the battery drains. I don't get an A/C icon on the task bar just the battery icon on the task bar as if the power supply is not plugged in (though it is). While the laptop is on and running on the battery and the power supply is plugged, the battery will not charge while it is on. It only charges the battery when the laptop is off. I have checked the power supply and it seems to put out the right voltage. Can it be software driven or is it the an area of the motherboard that has gone bad that controls the A/C section?\015

Hi cgarcia557
this does sounds like a problem with the toshiba power management utility.
Sounds like you've already verified the output voltage on the adapter.
The next thing i would check is for any looseness at the DC power jack on the laptop itself.
if this is snug and the center pin is not loose,
the next thing i would do would be to try reinstalling the toshiba power management utility;

\015\012Save this file to on your hard drive and then run it.
\015\012If this doesnt solve your problem, the next thing i would be looking at is a BIOS issue.
\015\012If you arent familiar with this type of procedure, its best to have someone on hand who has done a few successful BIOS flashes.
This is done at your own risk, but ive done a very good number of them on all makes and many models with never a problem.

Curious problem. Let's start. I don't think that the mobo is responsible for the problem.

I have a Toshiba 1405-s171 serial # 72154211P. The green power light would not go on, but the laptop would still function properly.
