Hi,
Accidentally, while fixing the cable I connected plus with minus. I attach the datasheet, if someone may take a look...
I measured some things before I started repairing:
Q8:
S: 19.4V
G: 19.0V
D: 0.01V
Q7:
S: 0V
G: 0V
D: 0V
Q642 and Q643 DSG = 0V
pin 26 U614 (bq24703) = 0V
comparator U606
1- output1 = 9,5V
2-in1- =6V
3- in1+ =6V
4 - GND
5-in2+ =5V
6-in2- =6,4V
7-out2 =18,7V
8-VCC =19,4V
I repleaced the comparator U606
Laptop is working but only on the battery. And the battery is recharging only when the notebook is turned OFF. When it's ON it works on the battery without recharging.
I measured U606 again:
1- output1 = 3,3V
2-in1- =5,9V
3- in1+ =7,3V
4 - GND
5-in2+ =5V
6-in2- =7,3V
7-out2 =0V
8-VCC =19,4V
Did I miss anything?
