There will be other issues in addition to all the above mentioned. With an attempt to change cpu, it is doubtful that the HP bios will properly recognize it. Voltages, timings and other parameters will not be correct. There is no guarantee that the MB components will interface properly with a different cpu as well. This means signal paths for things like sound, Ethernet, USB and other MB devices may not work at all. If this is your model (http://support.hp.com/us-en/product/HP-1000-Notebook-PC-series/5259215/model/5329629/document/c03548234/) you could try to add additional memory. In any event I would not try a cpu swap.
