It's an Ambit board, Rev 2, J071063.01
Nope, Dell pretty much mixes all Ambit products around in a big pile, puts a blindfold on and chooses another one for a different laptop line. 500M/600M/D500/D600 are all pretty much the same product though, so they probably all share this same part. Either Ambit makes a pretty shitty board or all different LCD's fall prey to the Dell touch of death; drop dead right after warranty expires!
I guess the only place I can get the part is from Dell; I called up 247laptoplcd and a lady said she may order the display assembly from a purchaser... who probably will get it from Dell... the only discount would be I probably don't need the LCD assembly. yay? :/
Wonder how much I can part out the laptop for..
