Hi, I have a problem that my computer doesnt work, and the laptop has a light when you get the power, and that light is not on, I tested the charger supplied with the multimeter and the current well, so I decided to open the laptop to take out the motherboard.

The 1 is the positive power plug, between 1 and 2, 3, 4,5 there are about 3 volts of potential difference.

The piece that has the connectors 6 and 7 is poorly welded,but, it makes a bad contact with the solder, however that does not offer unlimited resistance, so if there is a potential difference of 1 volt or less.

The piece having the connectors 11 and 10 there is always a potential difference of 3 volts but the part that has the connectors 13 and 12 all have potential difference of 0.38 volts.

The truth is that I have the feeling that failure is part 6 and 7.Can you tell me what is the name of this component. Thanks

I could answer your question, if I knew what laptop we're talking about. The make and model would be a start.

It is a asus x50sl, like http/www.winline.ru/img/2008/6/asus-x50sl-1.jpg the laptop has a label says 19voltios, 4.74 Amper 90w

When you connect the adapter in the dc jack you should have 19 volts between pin 1 and 2. If you have 3 volts then the adapter is defective or the dc jack.

The adapter is 19 volts is fine, do you think the problem may be the part 6 and 7, because 7 is broken connector, thanks very much

You should have 19 volts at the dc connector between the pin 1 and 2. If you don't have 19 volts the rest of the circuit won't have power.

do you know how much cost to repair that piece? I think i wont spend more time with it,
