My laptop is short circuiting, and now it can not turn on when I press the power button. the adapter light green but once i put it into the laptop and try to power it up, the adapter light turns off. I give a call to Dell Customer service to get some help, My god they said there are something wrong with my motherboard so I shoud replace a new one with 400$ (the laptop is out of warranty). If I can repair it by myself the 400$ is too expensive? The laptop is an Dell inspiron 1501 battery. Thanks!

When used Measureing between the power pins and then go to the back of the computer, consider the pins 2, where it is expected that the voltage on the AC adapter. If the resistance indicates a short circuit, this is bad.

The computer shuts off randomly
