Hey guys,

I have been researching alot for a laptop to use at college. I need one that is going to last a good few hours but also know that I can't trust the ratings that sites such as PC World, Dell, Hp etc give me (I live in the UK). Can someone help me as to how I can calculate/estimate the battery life myself? I have been looking at this laptop from HP, http://store.hp.com/UKStore/Merch/Product.aspx?id=X0N33EA&opt=ABU&sel=NTB

The specs of this laptop look perfect for my needs without the price being too horrible but it doesn't give enough information for me to know what battery life it is going to have nor does it tell me an estimate (not that it could be trusted).

It says that it has a "4-cell, 41 Wh Li-ion" battery and that a discrete model (i assume means it has a dedicated gpu?), is 65 W ( means watts?) and the alternative just 45 W. How can i calculate the battery life of this when doing microsoft office work, web browsing and maybe some really light gaming? I get that I can google the power requirements of the cpu but as for ssd, I dont know what one is in there so would not be able to find power requirements.

Sorry for the long wall of text and I really hope someone can help me out as this is driving me crazy lol.

Thanks for the fast reply. The problem is that there are some laptops that state up to 4 hours and then another laptop that seems to be equivielent spec will have up to 11 or something. How can i estimate myself the realistic battery life?

Again, best to read the reviews of the units you are interested in.
In particular, look at the workload that is tested for longevity and compare that to what you will be doing.
Battery life also, of course depends on the capacity of the battery. The trade off is longer life takes stronger batteries and consequently more weight.

The problem is, I cannot find a review for this laptop in particular. As in, they are always reviewing older models and even then, I only find 1 or two reviews.

Any ideas?
