Laptop and Power Inverter Problem

Hi.

I don't even know which automotive group would handle such a question...so
I started here.

I have a power inverter which plugs into my car's cigarette adapter. When
I switch it on, the "power" LED stays lit just fine. As soon as I try to
run my laptop off of the AC outlet, the LED comes off an on (without any
pattern to it) and the computer indicates it's on battery power, then back
to AC, then back to battery, etc.

Does anybody know of an easy solution for this? Is it possible that
something is not grounded properly to the car's chassis?

Thanks in advance for your assistance.

Looks to me that the inverter is too small for the load.

Yep. I just figured that out...

Inverter rating is 50W.

Laptop rating is:

120V, 1.5A in
19V, 3.16A out


19 x 3.16 = 60.04

My laptop is hungry...
