I've had a Toshiba T4400C for a while now, and it does work, but i can't get it to reliably turn on because i don't have a battery for it. The device will not turn on without a battery, but if you mess with the power button enough, it will turn on but only for a short time. Batteries for this computer are in around the $200 range, and i cannot afford that. Advice, anyone?
