Laptop powers up immediately when power cord plugged in

Hi, I've just purchased a refurbished Dell E6400 laptop a couple months ago, OS is OEM Win7 Pro. It is

working fine with no service affecting problems. There is one issue I've been unable to find a resolution for,

when using ac power the laptop powers up immediately when the power cord is plugged in. I've looked and

looked through the choices for power options, plans, etc... and haven't found anything about this particular

setting. I'd like it if when I plugged it in it would wait until I pressed the power button, I haven't found

anything indicating this is default with no option to change it, if it is I can live with it but would rather use

the power button to turn it on.

Hi,
Not a built in windows function,
You would most likely need to go through the dell utilities to find the feature,
Where did you buy the model ?

Thanks for the reply, I was unexpectedly called away from the computer causing my delayed reply.

I bought from this link a couple months ago Refurbished: Dell Latitude E6400 14? Notebook Intel Core 2 Duo 2.40Ghz, 4GB Memory, 120GB SSD, DVDROM, Windows 7 Professional 64-Bit - Newegg.com at the time I got a great deal, $238.

Here is the company that refurbished the laptop AST SERIAL NUMBER LOOK UP I looked up my serial number and this is the link.

I have a Toshiba Satellite & in the BIOS i have a setting to BOOT ON AC, it is disabled but if i enable it then i would have that function. so maybe you have the same setting in your BIOS.

That was it Stever1 checked the BIOS (F12 to access on this Dell) and there it was, big as the nose on my

face I guess I should have looked a little deeper but I thought it was a windows thing.

Thanks for the fix, you and Thrash get some kudos
