I just added 2 more GB to the laptop and the Windows XP got 4 GB of
RAM. I think I'm missing something, but the system shows only
3.24GB of RAM with the Physical Address Extension enabled. Maybe
it's related to the video memory which is shared on this model,
also it can be related to the video memory using its own address
ranges reserved by the system. So, although I'm not absolutely
sure, I could probably explain that.
But why the system still keeps 3.5GB swap file if I turn the
setting to maintain the swap file size by the system? Anyway it's
out of the physical address range and can't be used or I simpy
don't get it correctly. Windows XP has a 4GB memory address
limitation. Does anybody have a good explanation to this
phenomenon? System bug or something not documented? Should I
restrict the file size to something smaller?

32-bit Windows means you will not be able to fully utilize that 4GB of
memory in the way you expected. Either get a 64-bit version of Windows or
that's what you got.

And the swap file will be used no matter how much RAM you have.
