Hello, I just received a Dell Inspiron PA-12 Model: PP23LA. Is missing the Hard Drive and the ac adapter; the battery is dead (no charge). I purchased an AC adapter. When I connected the ac adapter to the power lines, the light on the adapter turns solid ON. I proceeded to connect the adapter to the laptop, now the light on the ac adapter blinks once every two seconds. When I press the power button on the laptop, nothing happens.I don't know what the problem could be. Help.
