Hi Gozoman.
On the plus side: -
You can fit a larger hard drive - check the old one as there is some confusion on this model. The specifications say it is an IDE Drive but some users here report they have a SATA Drive fitted. Make sure you do not get an Advanced Format Drive - check it has 512 bytes per sector.
You can increase the RAM to 2GB.
It is possible to upgrade the processor but it is probably not worth it. Your model has a Pentium M 740 which is a 1.7GHz, 32-bit processor. In theory, there are several slightly more powerful processors up to the M780, processor which is 2.27GHz, that will fit in the Socket 479 but other limitations of the system may make this not worth while. A refurbished one will cost about £90 - a second-hand one £50.
On the minus side: -
The processor family that will fit in this model is a single core, 32-bit processor and this cannot be upgraded to 64-bit.. You will not be able to run any 64-bit software and it will seem slow compared to dual core and more recent processors.
The Intel GMA 915 Graphics cannot handle any advanced features found in Vista, Windows 7 or Windows 8. Intel have not supported this chipset and the latest drivers are for XP. Graphics will be very basic and Aero will not work.
Your choice, but this model is made for use with XP and runs best on the original OS..
