사용자에게 답변하기: Power LED blinks blue 5 time .Press and hold the battery reset pin hole on the bottom of the laptop (google it to find out where, but just look you’ll find it). I used a pen ink and pushed and held it in for 5 seconds. You have to do it with the battery in. It didn’t work while the battery was out. With the back battery in, I pressed the power button and it turned right on.
