I hope I am posting in the right section of the forum. I have a Dell Inspiron e1505 notebook (laptop). it now won't power on! I checked if my power adapter has a problem, but my power adapter works fine when connected to my friend's laptop. When I switch on the power, the LED lamp on adapter is glowing green. As soon as I insert the adapter pin into my laptop, the LED turns off! And no LED on laptop would ever blink. Can somebody please guide me? Thank you!
