note: There two different Ram speed,
your laptop had 512mb ddr2 pc-5300 speed, you can choose to buy a same speed to add e.x a 2gig, because you have two Ram slot in your laptop, to have a total 2,512 memory.or 2gig with a speed of pc-6400 or if your rich directly buy a 4gig memory w/ a speed of pc-5300.make sure you if our planning too place two ram in your laptop make sure it as the same speed ok.
