The power led lights up when i press the power button, but dies afterwards. When I disassemble the laptop, then the laptop boots up. Only after the complete assembly, it wont start - just lights the power led for a second and does nothing. No beep sound, no caps lock light, nothing.
I am using just the plus and minus ( no earth cable ), because I am using a variable power supply. Even after grounding the laptop with an external cable, the problem persists.
Can anyone tell me what steps I should do to check this?
What is the signifgance of earth wires with respect to a notebook, because they are mobile devices and hence when running on battery, has anyways no way to earth itself?
