Your power controll circuit on the main board is bad, you might need to change that or the entire board itself.. If you can get a technician just to repair the power controll circuit you should be fine. most ppl dont do that cause its difficult. Normally your entire main board is replaced. To fix that i will need to see the board but thats difficult since i am sure you dont live anywhere close to trinidad but i am sure someone close to you will be able to repair it, or your can download your service manual for your laptop and attempt to repair it your self.

Had the exact same problem. New AC adapter fixed it.

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;

Save this file to on your hard drive and then run it.
If this doesnt solve your problem, the next thing i would be looking at is a BIOS issue.
If 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.
On that same page, the very first file listing is the one that you would need.

you will also need an external USB floppy drive.
If you want to undertake this, post back in here and i would be happy to help you with the procedure

If this has helped you, please dont forget to take the time to rate, that gives us the satisfaction that a problem was solved
