|Did the factory service techs find anything wrong with it? |
If you've had factory service on it, and it still doesn't work, I would contact the people who fixed it and complain.
It seems that there are a fair amount of Toshiba laptops out there (w/ Google searches) with these types of power issues.
It could be a range of issues:
- Mobo issues, MOBO AC connector issue, RAM issue.
- Bad cooling FAN(s)
- Loose CPU heat sink
- Power AC adapter issue, bad cords, bad barrel connector.
- Charging system not charging battery
- System short circuits
- Power Management Software glitches
Just another stupid saying...
