Hello Kenobi,
That would be about right.
Since it's 32-bit, it will actually only use about 3.6 GB out of the 4 GB with .4 GB reserved for hardware.
Since it's a laptop, you will have an integrated graphics chip that uses allocated RAM for it's memory usage. In this case, most likely 1 GB.
This leaves you the 2.6 GB usable.
