Anybody know how difficult it is to upgrade this laptop? Several websites state it will run much better by a memory upgrade (purchased with 512 MB memory)- is that true? How difficult is it to do the upgrade- DIY or not? Can you upgrade anything else easy - want to just do home pics, email, etc. - no gaming or heavy video stuff. The sites that are selling the memory upgrades suggest a 1gb stick - the specs say I can fit 2gb total -- so should I get two 1gb memory sticks. Any name brand memory will do ?? or suggest a specific buy would be great. This is a fairly old notebook- but it is still working great - so hate to trash it. Still has XP in it- upgrade to Win7 or not? Sorry for all the questions in one thread.
