Hello, the laptop doesn't start, the 2N converter (RT8249CGQW) heats up, it still warms up after the replacement. After flooding, the laptop was cleaned in another service and worked well for six months.Current consumption: 0.170A before pressing the switch, after pressing it without changes. Pins resistance:
1- 21 kohm
2- 4,4 kohm
3- 0,2 mohm - only here 0,8V appears
4- 8,5kohm
5- 29,6 kohm
6- 100 kohm
7- 66 kohm
8- 12,7 kohm
9- 8,8 mohm
10- 24kohm
11- 4,6 mohm
12- 1,7 mohm
13- 0,5 mohm
14- 3,7 kohm
15- 4,6 mohm
16- 3,7 kohm
17- 8,7 mohm
18- 3,7 kohm
19- out of range
20- 91 kohm.
Additionally I measured coils:
1- 2,5 mohm 0.2V
2- 0,22 kohm 0V
3- 0,37kohm 0V
4- 2,4ohm 0v
5- 2,4ohm 0v
6- 6ohm 0v
7- 3,7ohm 0v
8- 3,7ohm 0v
9- 74ohm 0v
10- 0,35kohm and grows up, 0V
11- 90ohm and it grows upwards, as 2N warms up the resistance drops to about 10ohm, 0V
