I did yesterday buy a new Toshiba c55-b5299 notebook from Office Depot for $220. Now my question is that how do I open the back lid so I can put a 8GB DDR3L ram? I' am sorta a computer geek so I have upgraded rams before but for some reason it says on the site that its not user upgradeable. Does this mean that just by taking screws out won't take off the lid easily? Also need to know which screws is for removing the lid or bottom cover. Or am I not suppose to do this myself and have to take it to a tech like Geek Squad or DIT corp?
