I was trying to replace a bundled 2230 SSD with 2280 and move 2230 to the second slot. But now that I unscrewed 2230 from the original slot, I cannot move the mounting bracket as described in the manual 

the bracket in me laptop seems different and doesn't move

it seems that it's fixated on purpose with those two clips

does it mean that I cannot install 2280 on my laptop??? Or how I do it?
