Re: HP G6 DA0R13MB6E1 QUANTA R13 REV. E / No power, No LEDs...

yes thank you very much very kind ... but I had to take them in another motherboard how can I measure if they can go well? because on the cards the value is not marked ... with the tester how can I measure the value of the capacitor that I would like to take from another motherboard?

This would impractical. You'd have to desolder every component you want to test. A resistor could be easy to find though.. Just look for a 220 marked resistor in the same package.

Capacitors are another thing.. You can't measure them if you don't have a capacitance meter. You could get a schematic for your donor board and search one.

I have this motherboard with this scheme ... where can I get the parts I need?

Re: HP G6 DA0R13MB6E1 QUANTA R13 REV. E / No power, No LEDs...

just search for 100nF and 220pF in the schematic.

As example:
C1372 => 220pF / 50V
C1324 => 100nF / 10V

sorry for the bad welds but having the soldering iron with a big tip I can't do better ... sorry ... anyway I inserted the capacitors and a resistance with bigger dimensions not as a value but as a measure but as soon as I put the current it goes to smoke

I really hope that this is your personal laptop and please invest into a proper soldering station.

Anyways.. Look at the image and measure resistance.

ehehehe ... thank you so much for the advice ... as soon as I have the chance :-( ... I have measured red where you have marked you and black where the vito go to 2000k but I'm not giving any value ...

C26 not on straight,EC4 end cap missing needs replacing,PC103 needs replacing, PC48 needs replacing . Do yourself a favour,buy another soldering iron or a smaller tip and some good quality flux, use lots of flux don`t be sparing with it.

Re: HP G6 DA0R13MB6E1 QUANTA R13 REV. E / No power, No LEDs...

sorry you are right ... can you tell me the values of the capacitors to change in order to take them from another motherboard?

Re: HP G6 DA0R13MB6E1 QUANTA R13 REV. E / No power, No LEDs...

c26 is not right in the sense I have to redirect it or is it upside down? ec4 do you think it is wrong and should it be changed? pc103 has already been changed but I thought the component was c20 and not pc103 putting a 220pF / 50v capacitor ... pc48 is shorted?

hi, I wanted to ask in order to solve the problem I have to change all those components?

Re: HP G6 DA0R13MB6E1 QUANTA R13 REV. E / No power, No LEDs...

I have done better the welds now the pubto of the resistance on the left + gnd brings me 150.5 and goes to increase I put the tester to 200k

I really hope that this is your personal laptop and please invest into a proper soldering station.

Anyways.. Look at the image and measure resistance.

any suggestions ?

Do you have a bench power supply ?

Re: HP G6 DA0R13MB6E1 QUANTA R13 REV. E / No power, No LEDs...

Unfortunately no

Ok..

Remove PC16 and try to power it up. If PR12 still smokes PU2 is most likely dead and needs to be replaced.

Also measure voltage across the resistor. Put each probe on one side of PR12. Meter should be set to DC Volts.
Do that while it is on of course.. Do it quick so it doesn't burn the board.

ok ... I have to change the resistance first ... measuring before he smoked he took me with the rester in ohm 22.6 now smoking he brings me 00.1 or 00.2 so I think it must be changed ... I change it and then I measure the resistance again with volt cc

Usually resistors fail open circuit. Are you sure that the resistor is 0Ohm? Desolder it and measure.

Re: HP G6 DA0R13MB6E1 QUANTA R13 REV. E / No power, No LEDs...

I have just measured the resistance in volt cc without removing it and it brings me 023
