I am working on our laptop it is a dell inspiron 600m, the laptop will not power on. We bought a new power supply, because we thought that was at fault but the new one is doing the same thing. No response at all when the power button is pushed and when you plug the power cord to the laptop the LED on the power supply cuts out. Then you have to unplug it and plug it back in again to make the lgiht come on, when the LED goes out there is no power at all on the power plug.
The battery indicator shows up at 3/4 charge and even when the cable is unplugged the laptop will still not power on.
I am stumped and appreciate the help.
