Hello,

I've recived a HP 15 dead with no power and no LED light on DC Jack.
There are no shorts and it don't detect the battery.

On BQ24738H, i have this voltages (without battery):

1-ACN 19.5v
2-ACP 19.5v
3-CMSRC 19.5v
4-ACDRV 25v
5-ACOK 2.9v
6-ACDET - 2.65v
7-IOUT 0v
8-SDA 0v
9-SCL 0v
10-ILIM 0v
11-BATDDRV 3.1v
12-SRN 3.1v
13-SRP 3.1v
14-GND
15-LODRV 0
16-REGN 6v
17-BTST 5.8v
18-HIDRV 3v
19-PHASE 3v
20-VCC 19v

I think i need IOUT (3v) to start SIO (8987e), right? I already change teh BQ738H for 738 and same reasult, any tip?

Thanks

I think, you should check the center pin (needle) of the power supply.
The 24738 is all right.

In the middle pin i have 11.5v (disconected from motherboard).

On CN on the board i have:

1 and 2 Red Wires - 19,5v
5 Brown - 0,5v (must be 3v or semething right?)
6 an 7 White and Yellow - 4.95v

PS: tested with original charger and switching PSU.

Not right, must be 05-0.6V (AC adapter 65W)

SIO problem?
