I have removed all accessories for the the tests, ie., memory hard drive, optical drive, battery..
My power supply adapter shows power indication before I connect it to the D630. The moment laptop is connected the power adapter goes to lights out. and I can't see the power LED on the laptop light up.
I have tried with different DELL power supplies both 65W and 90W.
It feels as though the power supply goes into a short circuit shudown mode. To get the power adapter working, I have to disconnect the laptop and recycle power on the AC mains.
Is this a common problem and what could be the possible issue ?
