PC Wizard can show you how many RAM sticks you have.
Other wise, you can take the panel off of the underside that covers the RAM, and see how many slots it has. If theres 2 slots, 4 GIGs should be the max, as the highest laptop RAM sticks can be is 2 GIGs per stick.
Now on the OS side, there is a 3 GIG limitation on 32-bit windows, and with 64-bit, there is iirc, 16 GIG limit. Tho, you can install more than the limit.
Even further, the BIOS and the motherboards north or south chips might have a limit to the amount of RAM usable. Case in point, my laptop has 4 GIGs of RAM installed, and i have a 64-bit version of Windows 7, it recognizes 4 GIGs, but says only 3 is usable.
ALSO, you could google your laptops model number and see if it says what the maximum expandable memory is.
