Most laptops can easily reach the 4 hours mark yo
If want light weight, then ultrabooks would be nice, but are a little bit more expensive:

Pretty impressive specifications for the price I would have to say

Your A43Sv is probably running on an i7?
well, battery runtimes rely very much on what you are doing with your laptop, and how bright your LCD screen is yo 

I see, iinm, the previous A series were known to have smaller capacity batteries, don't really remember liao haha XD
The thing about battery is that they tend to degrade over time too 
Especially true for those that are non-removable

Thanks for the quick reply. Actually I'm asking for a friend
Should he get the one with 32GB SSD caching or just the normal one?

Looking at both HP and Dell Inspiron, Dell seems to have slightly better specs + DVD drive, just extra RM100. But HP's design and battery life seems to be better

And are there any notable issues with the Envy 4?
