email to a friend As long as I care to remember, battery life has always been a concern for laptops. Minor advances in battery technology have been offset by computers requiring more juice to function, and it's only recently that a number of laptops have been advertised with six-hour single-battery longevity.
Just last week, however, Dell made a bold claim with its new-model Centrino 2 Latitude laptops, citing a 19-hour battery life by combining a 9-cell battery with a 12-cell 'pack' that sits underneath the machine.
Now, at IDF Fall 2008, HP announced a new line of EliteBook business laptops that cover the entire size range, from thin-and-light SKUs to quad-core-toting workstation-based beasts.
In particular, and arousing considerable interest, was the declaration that the EliteBook 6930p, equipped with HP's Ultra-Capacity Battery on top of the shipping model, could run a whole day - 24 hours - without having to hit the mains.
HP's execs were keen to point out that the boast, internally demonstrated via MobileMark numbers, was facilitated by the use of Intel's upcoming solid-state drives, which pull only 0.15W when under load.
A whole day without going to the mains - we'll believe it when we see it.

The latitudes are more appealing to me though.Quote
either way as long as its still lugable, thats very useful.Quote
Im sure that eventually, cd's, hard drives or any moving parts will be replaced with solid state eventually. Maybe by 2012, there will have been some great advances in mobile tech.Quote
I'm thinking that even if you can't get "24 hours" using more standard settings (reasonably bright screen rather than dim, etc) having a spare battery "in your bag" would definitely take you up to and beyond the 24 hour "plateau".
IMHO, it would only need to last < or = 16 hours, bcs nobody works more than that IN A DAY. After that, you can plug it in.
Edit: I wonder how long it takes to charge? This is done with a 9 cell and a 12 cell, right? I'd guess about 15minutes a cell, so (if batteries are not charged independently) about (21/4 =) 5h15m. Anyone agree/disagree?Quote
