    Here's the specs for your laptop:

    It indicates that the processor is an Celeron B800. According to Intel, that processor uses the FCPGA988 socket.

    Intel® Celeron® Processor B800 (2M Cache, 1.50 GHz) Product Specifications

    The Xeon E5205, on the other hand uses the LGA771 socket.

    Intel® Xeon® Processor E5205 (6M Cache, 1.86 GHz, 1066 MHz FSB) Product Specifications

    So they won't fit each other. Also there are other problems, such as the Xeon is a 65W processor while the Celeron is a 35W one, etc.

    Compaq notebook/s have the CPU Soldered to the Motherboard.  They can not be changed.

    First thought, practically impossible. Before digging into a lot of details, seeing only XEON and Notebook, Laptops often have soldered CPUs. Laptops can have authorized CPUs in a list in the BIOS preventing any other. Laptop CPUs need to be socket, wattage, and core logic chipset compatible. You ask about a desktop SERVER CPU compatibility into a laptop. The chipsets and sockets and wattages are all different between Desktop and laptop.

    1.50 GHz Intel Celeron Processor B800 1333 MHz FSB

    Socket G2 / rPGA988B

    E5205 is an incompatible package Socket 771 / LGA771

    There will be Zero desktop-Server CPUs compatible with that laptop.

    The service guide is still available for that laptop:

    You cannot even use the table of CPUs entirely.

    First, System Board 646174-001, officially unique.

    GM45 UMA chipset seems to be on that HP number

    Intel shows that the laptop used an old design motherboard, not even compatible to core i CPUs at all

    But according to Intel, Intel HM65 Express    Intel QM67 ExpressIntel HM67 Express are the only compatible to the B600

    Very strange conflicting information on what was their cheapest CQ57 in year 2012.

    So, the only way to know what is happening and whether HP provided bad data is to determine the marking on the chipset of the motherboard for HM65

    One blog said to update the bios to be a CQ57 model compatible to i3-2310m and that CPU works.

    B800 scores 1273. You may be limited to about 35 watts

    i3-2310M scores 2433

    The old Xeon E5205 scores only 1401.

    Even if it worked, you would not upgrade from one low performance CPU to one just slightly better. That Xeon is trash/garbage.

    If you know what you are doing, you might find a laptop CPU and Bios upgrade and matching used old core i3 CPU

    No. Completely different socket.
