A friend gave me a Laptop, NEC Versa 2000D Laptop to look at to see if I could determine what is wrong with it. Tried to power it up with the power adapter connected, but system will not power up. In fact the green on/off power light doesn’t even come on. Therefore, I believe it must be power related. Planned to begin with the power pact, but I thought, shouldn't the system at least power up with the power adapter I connected? But it doesn't. So, my question is, any suggestion on what maybe the cause and where else to look at? Thanks in advance for any tips or suggestions.
