NEW Laptop/Notebook Battery for HP/Compaq nc6400 nx6110 nx6320 nx6325 nx6120 nc6320 nx6310 nx6130 hstnn-db28

okay hello everybody what I'm doing here is my dad sent me his HP laptop it's a NC 6400 HP focus their Co 6400 and what's interesting about these model laptops is first of all their business class they have core twos and this one has 4 gigs of RAM and I think like an 80 gig mechanical drive and what I'm doing what this one is it doesn't work when I turn it on lights on but it won't power up she's dead and there's nothing on the display nothing happens so what we're going to do is I've already researched it and these monies are here the motherboards go bad because the the ATI display display card the graphics card they go bad and it's not necessarily the card itself goes bad it's actually the solder joints go bad and what we got to do is see if it's the backlighting you would see the windows 7 logo shine up when I show this into the screen so it's not a backlighting issue but so well the
