Dell Inspiron 1502 Power adapter light goes off

Hello,

I came to the post linked below as I have a similar problem:

Possible solutions for burnt-out circuitry on Dell Latitude D505 mobo?


I have the same problem with a Dell inspiron 1520, when I connect the power adapter to the wall plug the green led lights on, but as soon as I connect it to the laptop the light turns off.

I have ruled out the adapter being a problem as I tested it on another inspiron 1520 and it works fine, while another adapter does the same on the "bad" inspiron 1520.

I opened and removed the motherboard, it has 5 capacitors PC1 to PC5 close to the plug for the power adapter and they all seem fine with resistance of 0.5kohms to 250kohms. I then checked the PC capacitors close the the connector for the battery (it has like 20 with the "PC" mark) and at least half of them show a resistance of 1.3Ohms.

Is that normal or with such low resistance I can consider them as being in short circuit?

Any ideas on what else to look at? Or maybe the mother board is beyond repair?

Thanks in advance
