Will the expansion card slide out if you try to unplug a cable from the expansion card? Some cables may have tight connectors so that they won’t become loose easily. Do you think that this will be a problem? The expansion card has to be both easy to remove to replace it with another card and hard to remove to not slide out if you unplug the cable. It is a kind of dilemma.
The Expansion card has a latch on the laptop that will keep it in place when you remove the cable.
You can easily replace the expansion card by pressing the latch, and sliding the expansion card out.
