aircraft/auto power adapter

Looks like empower jacks are limitted to 75 watts...you're going to be hard pressed to run the 5150 on that power I think.

Crikes, I was wrong...the Kensington doesn't have a tip for the 5150 acording to their site....I'll keep looking.

Dell doesn't make one. The DC airpower adapter they have is only good for 65 watts (and you need 90 or better for laptops like the 5150 and XPS's). The good news is that they are available. Kensington makes one www.kensington.com, just go to their website and select notebooks and you can dial up DELL and 5150 in the menus and they will show you the things they make that are compatible.

Hey natalie I went to HP and they have a 90W air/auto AC adapter  it looks ok, but I really don't know if it will work with my 5150.
