Re: Toshiba Satellite A300 NO LED/NO POWER

Because its the Charge/Power controller so I think can be it...or not. Anyway I´m gonna try measure all diodes, resistors and mosfets around the power and charging circuit and check if there is Vcc on the IC U803.

Re: Toshiba Satellite A300 NO LED/NO POWER

Hi there. I have the same problem on my A300. With battery charged works fine. With charger connected doesn´t charge the battery and no indication of external power connected. Without battery doesn´t work (no power indication either). Charger works fine (tested on other laptop) and DC jack is fine (with power connected the 19V is present on the jack pins on the mobo). I think the problem is on the power control IC U803 24721C. Did anyone had and resolved this problem ? Thank you.
