Sorry to hear of your delima, but since you didn't replace the defective power adaptor when it failed the first time, it sounds like it did a lot of damage after you continued to use it. I looks like the charging circuits are fried....while you could have it replaced....for the cost, it may be worth it to just get another laptop....I'm surprised at all the problems you have....I've had a lot of Toshiba's (have one now) and I find them very well built and hold up well to my abuse...even as a instructor!
