Yeah, my dads laptop (made by Pavilon or something), its pretty rubbish, and even though it has a 1.0ghz processor, its nothing like that fast because it uses a custom processor by Realtek or something...
Anyhow, this laptops my dads got is noisy and the fan stays on all the time. More powerful note books are alot quiter and you cant even hear them most of the time.
The battery life on that laptop lasts just about 1 1/2 hours...pretty sucky I know.
So 5 hours seemed quite alot to me when I saw it on the post.
