The new battery goes in at an angle and you press again and it will click into place.  If you try to pry it with a screwdriver the battery will come out and it will break the plastic holding it in.  This means you must replace the socket because its now broken. DO NOT USE METAL SCRIBE This tool kit has the appropriate piece the black stick with hooked end.

I have a Dell XPS 8900.  Same problem as everyone else:  the power switch does not work.  Want to start by removing, testing and replacing the battery.  However, this battery holder/compartment does not look like all the other ones I have seen!  It is not the same as the one pictured in the xps 8900 Service Manual nor any of the ones I have seen on YouTube videos.  There is no clip on the battery holder.  It is solid plastic, all the way around.  No spring, no clip.  On top of that, the space to get tools or fingers near the battery is very, very cramped.  How do I get this battery out?  What is the trick to remove it? [IMAGE][IMAGE]
