Hello!
I have an HP Pavilion DV6-6141s with a motherboard HPMH-41-AB6200-E00G, which, when connecting the power, turns on the jack led, but does not respond to the power button. A few days before, it does it randomly, sometimes it turned on and other times it didn't.
I have verified that the 3.3VSTBY signal is not generated, so I have taken the measurements of PU9, which are the following:
1. (EN1)ENTRIP1 ... 0V
2. (5V FB) VFB1 ... 0V
3. VREF .... 2V
4. TONSEL ... 4,98V
5. (3V3 FB) VFB2 ... 0V
6. (EN2) ENTRIP2 ... 1,16V
7. (3V3 SRC) VO2 ... 0V
8. (LDO3) VREG3 ... 3,3V
9. VBST2 ... 4,78V
10. (3V3 DH) DRVH2 ... 0V
11. (3V3 LX) LL2 ... 0V
12. (3V3 DL) DRV L2 ... 5,30V
13. EN0 ... 18,7V
14. SKIPSEL ... 4,98V
16. VIN ... 18,9V
17. (LDO5) VREG5 ... 4,98V
18. VCLK ... 0V
19. (5V DL) DRVL1 ... 5V
20. (5V_LX) LL1 ... 0V
21. (5V_DH) DVRH1 ... 0V
22. VBST1 ... 4,5V
23. PGOOD ... 0V
24. VO1 ... 0V

Hola!
Tengo un HP Pavilion DV6-6141s con placa base HPMH-41-AB6200-E00G, el cual, al conectar la alimentacion enciende el led jack, pero no responde al boton de encendido. Unos dias antes, lo hace de forma aleatoria, a veces encendia y otras no.
He comprobado que la señal 3.3VSTBY no se genera, asi que he tomado las mediciones de PU9, que son las siguientes:
