Upgrade laptop memory /replace dvd drive?

[Demoniser]

I have an Acer 5920G(H) laptop and was wondering about getting it upgraded to 4gb of ram (currently) 2gb if it's possible and also would it be possible to replace the HD Dvd Drive with a Blu Ray one?

I thought this would be the best place to ask I haven't a clue lol.

Cheers for any help if anyone knows how to go about this.

ok, had a quick readthrough, what you need is in this file:

I've been thinking about a ram upgrade myself, OcUK looks good for both the ram and the sony blu-ray drive....
