Hello all,
I'm not sure who to send this to. There is an error in the owners manual for the Latitude E7450. To remove the base cover, the manual says to remove the battery, remove the two retaining screws and then pry the base cover off. This is completely incorrect, and will result in a broken base cover. The correct way to remove it is to remove the two retaining screws under the battery, then simply SLIDE the base cover TOWARDS the empty battery compartment, and lift up. No prying necessary.
Prying the cover up will result in breaking off it's little retaining tabs inside. Ask me how I know...
Anyway, if someone from Dell is watching this forum, please get this corrected in the owner's manual. It caused me to damage the base cover on an E7450, breaking off two internal tabs, one of which tore a small hole through the cover.
Also, the owners manual does not mention replacing or upgrading RAM, which is right below the base cover.
