When I have the laptop off (Toshiba A75-S229) the ac power light is on and the battery charge light is on. As soon as I turn on and it starts to open windows the charge light goes off. Then as windows opens the laptop runs only on battery even though the ac light is on. Except if I enter bios then the battery keeps charging. Just wondering if anyone knows a setting or conflict that would keep laptop from switching to ac from battery? Or could there be something in msconfig that I could check?
