The Intel(R) Core(TM) 2 Duo Mobile processor T5250 is based on a different technology than the Intel(R) Pentium(R) M processor 750, I do not believe that the laptop supprting the Intel(R) Pentium(R) M processor 750 will support also the Intel(R) Core(TM) 2 Duo Mobile processor T5250, anyways, I would recommend contacting the laptop manufacturer for them to provide you a list of fully supported processors for your laptop, and if it does support the Intel(R) Core(TM) 2 Duo Mobile processor T5250, then check with them to see if the laptop requires a BIOS update, keep in mind that the compatibility between the processor and the laptop is determined by the laptop manufacturer, not by the processor manufacturer.
