RE: Can I Change Dell Inspiron 15 7000 Graphic Card ?

All current Intel CPUs ending in U for notebooks are BGA (soldered).  If you look at Intel's roadmap, it plans to convert all mobile CPUs and many desktop CPUs to  BGA-only format.  The majority of the Haswell mobile CPUs are of this design.

Don't know about the7-beep code but it's been my experience that CPUs very, very, very rarely are the cause - much more common is a mainboard failure.
