HP Pavillion G6. no power

[lorins_core]

have a nice day to all.

i Have repair hp g6 no power. if i plug the charger have no light indication. if i press the power on switch. the light indication blink then off, only if the battery inserted.

i try to measured the voltage.


i have a good unit to trace and i swap this parts i circled green
can you check


Same Problem...

Help me how to fix this

flash u13 bios it will work

flash u13 bios it will work

thanks i'll appreciate your answer.

how can i to that? can you teach me step by step

Re: HP Pavillion G6. no power

do you have a bios programmer? you need to remove chip from the board then flash it on programmer.

thank you pare... for your thinking of this problem it is a bios problem or hardware?

can you give me the best solution for this. teach me how please.

thanks again

Re: HP Pavillion G6. no power

Whenever I have an HP or Compaq laptop with charger indicator the does not lit, first I do is flash bios with proper dump file. You should try that first.

If not try to touch charger IC (PU9) and 5v/3v regulator IC (PU3) if its heating up. If it does there's a short somewhere.

Re: HP Pavillion G6. no power

in this case. i all ready to change the PU3 and PU9. i have a available unit same as this model. i swap both parts then i test. the good one still okey booting up. but the one have problem it a same.

btw: the IC (PU9) and (PU3) not heat up...

but i notice this parts i try to Trace this on may Voltmeter analog. wait i edit...

Thanks

Re: HP Pavillion G6. no power

This is a good and working one. i test the voltage of 2 parts
show up this


Prove set 10v Voltmeter. tap the black on GND then The red inject to pins 1- 2 -3
PQ44
pin1 - 0V
pin2 - 0V (gnd)
pin3 - 2V


PQ45 mosfet
pin1 (S)- 3V
pin2 (G)- 2V
pin3 (D)- 3V

see below




here's the prove check board have problem
Prove set 10v Voltmeter. tap the black on GND then The red inject to pins 1- 2 -3
PQ44
pin1 - 0V
pin2 - 0V (gnd)
pin3 - 2V

What happen to this? PIN1(S) and PIN3(D)
PQ45 mosfet
pin1 (S)- 0V
pin2 (G)- 2V
pin3 (D)- 0V

how to ix this?
Thanks

Re: HP Pavillion G6. no power

hi lorins
tell me one thing. you will check voltage on pin no 20 on pu2 (19v)
and pr94 near pu3 it has also get 19v, pr62 4.62v if all the voltages are ok then check
3.3v on u13 at pin no 7,8. if avail flash the bios

PU2- pin check pin 20 = 19V
Pr94- 0v

pu3= what pin i check

u13=?

thanks

Re: HP Pavillion G6. no power

i notice again the +5VPCU?

or Missing the Supply of this type of Supply +5VPCU

where the location of this source...

Re: HP Pavillion G6. no power

Wait. I think you started the wrong way.
When you want people to help you write the model of the board and if you have a schematic share it or point to the location of it, Mitu Sharma probably is looking at the wrong schematic and gives you wrong information.

Mitu Sharma and Lezsimply, lorins core described in his problem that when he attaches the battery and presses the power button the light indication blinks (that is the laptop tries to start) which in my opinion has to do with a short somewhere and not bios.

I will never advise a person to flash the bios before i had checked that everything is ok (I have always voltages and the ec controller functions) and I do not have data signals from the bios ic (although in this situation may be a faulty chipset - very rare) or the laptop starts but it fails to boot (although in this situation may be again a faulty chipset).

I got sick of seeing people asking for bios dumps. Flashing the wrong bios or a bad bios file may make the problem more complicated.

Check pins 8 and 17 of PU3 and PL21, PL20 for resistance relative to ground without power plugged in and voltage when you plug in the adaptor.

Re: HP Pavillion G6. no power

you are right atsio
i am looking wrong schematic
sorry for that .

lornis please send me proper model no of motherboard

PU3
PIN 8- 50ohms (5ohms X10 selected) Analog type ohmmeter
PIN 17- 60ohms (6ohms X10 selected) Analog type ohmmeter

Coil
PL21-1.9 OHM read X10
PL20- 1.9 OHM read x10


Thank Mr.Atsio

unit model Hp G6
mobo : DA0R12MB6E0

Re: HP Pavillion G6. no power

Do you have any voltage on these points (pins 8 and 17 of PU3 and PL21, PL20);

Re: HP Pavillion G6. no power

I have G6 R33 motherboard... when i connect adapter plugging light on....after few second charging light (Orange led) on..that time battery already removed. after few second ...again pluggin light blinking few times and off...

if battery inserted and plug the charger, then press power on switch the light indicating on charging terminal white light 3 times light and off the light.

but i notice have no light on charging terminal white light or orange. no indicating charging.

sorry to late post


PU3 Reading

PIN8 - 0.9V
PIN17- 0V

PL20 - 0V
PL21 - 0V

What can I Do to next step MR. Atsio. Thank and Advance

Re: HP Pavillion G6. no power

@atsio yeah you're right. I missed the battery part.
