it was a screen issue and it wouldnt turn on. it wasnt recognized by my computer either so it's not just a screen issue I figured it was a power issue too so I (STUPIDLY) tried to remove the battery and see what the problem was. I think I busted the battery because now (I've never smelled it before) but I think it's leaking battery acid. meaning I completely destroyed the battery

On another note, this is a completely different issue,but I have a windows 7 computer and the sceen is broken a
and the screen is broken


it works great when I hook it to hdmi,but I have a toshiba that has windows vista 32-bit. I'm wanting to upgrade both to windows 10 because it is free right now
but in order to do that I need to upgrade my vista to windows 7-64 bit. I know that I need a product key in order to do that so is it possible to use the key that is on my toshiba laptop and use it again to download windows 7 on my acer that uses vista?
