Alpha and Omega semiconductor strikes again.

It's pretty wierd as I am reading this I have the same model a Dell Latitude D510 on the bench now that crappy proprietary DC jack decided to fall apart.

It's got a very thin 3rd pin for data if the mobo doesn't recieve the data from this pin the battery won't charge but the laptop will run off AC very annoying.

Just got done removing the old one and ordered a replacement.

Be sure to check that jack out while you're in there if it's structurally sound check the solder joints. You don't want to have to deal with it later.

Re: Mosfet Identification

Someone needs to make a corporate logo id guide to make ID of things like this faster. Most of dell's line has that 3rd pin. Its very annoying when you have a similar power supply and it still refuses to charge the battery. I hate both the 3prong and the circle and center pin variety. At least its not as bad as the mac plug.
