You can buy more RAM for your laptop, i've added an extra 1.5gb in mine. Have a look at ebuyer, but the best thing to do is switch your laptop off completely, open the back, take your existing ram stick out, write down the name/details of it etc, then search on ebuyer or other places to find the same model but larger obviously. Also it depends on how many slots you have (they're next to eachother), you may get 1-3gb in older notebooks.
