Hi guys.
Laptop is not reacting to power button at all, no lights, no blinks no beeps or anything. Removed every component and the battery too.
DCIN 20v is present until the first mosfet, but not at its gate.
(SUSPECTING the BQ735 charger chip bacuse it worked from battery while it had some power.)
So made some voltage readings on BQ735 below:
1 ACN - 0.906 v
2 ACP - 0.906 v
3 CMSRC - 0v
4 ACDRV - 0v
5 ACOK- 0v
6 ACDET - 2,75 v
7 IOUT - 0v
8 SDA- 0v
9 SCL - 0v
10 ILIM - 0v
11 BATDRV - 2,12 v
12 SRN - 1,07 v
13 SRP - 1,07 v
14 - GND
15 LODRV - 0
16 REGN - 6,08 v
17 BSTR - 5,9 v
18 HIDRV - 1,07 v
19 PHASE - 1,07 v
20 VCC - 20 v
