Re: Toshiba C850 only wants AC power
Keyboard controller is bit misleading name to this chip
Those 3.3V voltages from Battery connetor go to KBC chip etc...
If FDMC884 replacing not help, you can check what is your motherboard manufacturer ( quanta? ).
Same manufaturer has very similar schematic even componet name are different....

Re: Toshiba C850 only wants AC power
a few things that could explain the problem at Battery present no boot.
1. AC Voltage go directly to Battery.
2. Keyboard controller is broken.
3. Something else?...

Re: Hp dv6700
Yes, PQ61 is MosFet on DV6700 intel motherboard.
You have other model and there is different names.
What is your motherboard type and is it Intel or Amd?...

Re: Hp dv6700
Do we have same shematics DV 6700 Intel_quanta_at3?
I quess I have different schematics. Can you post your schematic?
PQ61 should be near AC Input and it should be 8 Pin Mosfet....Last edited by Tuomo; 05-21-2013, 11:56 AM.

Re: Hp dv6700
I think you should start measuring PQ61 voltages....

Re: HP 425 No power
First 3VA and 5VA always voltages U519 have to works.
Check those voltages....

Re: Sony vaio VPC-EB mbx223/ no start,no power no led
Measure PU3 PIN5 ACDET.
This detect if AC Power is inserted.
Measure PU3 PIN4 ACDRV# should be LOW....Last edited by Tuomo; 05-19-2013, 07:53 AM.

Re: Toshiba L650 power problem
ACIN PIN19 1.69V indicate at there is AC Adapter inserted.
If ACIN PIN19 > 1.485V then ACOK = 0V.
ACOK PIN10 5.34V means at AC Adapter NOT detected.
If other voltages are OK, then U6000 may be FAILED....

Re: Toshiba L650 power problem
No, just AC Adapter not detected.
Measure PIN 19 ACIN this is pin which detect AC Adapter....
