i checked youtube vids and ebay, and those m6400's look different than mine !!
pic shows my laptop, battery seems to need a thick side and a flat side! what kind of battery do i need? the ebay batteries were long and thick all the way across like a regular battery !
second, next to the battery case here i put in a hard drive on the right... is that my primary drive, or the secondary ?? and i am looking for the right "caddy" for that one on ebay ??
third, above battery case, is that the space for the other drive? youtube ones were showing i had to open up the screws to release something, but i dont see any other place to put one except right on top. which raises the question: connection! which caddy or connector do i need? i am confused by the pics on ebay! it is not a direct fit with the drive.
so: which ebay battery do i need, which caddy and connector for each hard drive??
those m6400 vids did not look the same, and the ebay listings are not clear either.
