may be in the market for a mobile laptop with decent hardware specs that can get 7+ hours battery life.

IBM Thinkpads are the only ones I can think of.

you could buy a pentium m / turion laptop with dedicated graphiks. that should give you about 4h of batterie life. if you buy an extra main battery should get the run time you are looking for.

Try to look for
Pentium M 90nm with 400 MHz FSB (Dothan)
with Intel 855GM chipset (Odem)
OR
Ultra-low voltage Pentium M's.

I think IBM/Lenovo X series is a good choice. X40, X32, etc.

Sonoma + Alviso (P-M with 533 MHz FSB) sucks for battery life.
The same goes for Turion.
However, if you plug two batteries into these systems (main battery + travel battery), you might get decent battery lives, but I think 7 hours is still pretty hard to achieve.

I used to have a Thinkpad 390X... I could swap the DVD drive for a 2nd battery, and I could get pretty close to 7 hours with both batteries in....

To achieve such a long battery life, I recommend that you look for a laptop with a Pentium M CPU, integrated graphics, a smallish screen (14.1" or under) and an optional enlarged battery or dual batteries. Note that a larger battery usually sticks out from the laptop.

I suggest you consider the Lenovo Thinkpad line, the Dell 600m with dual 6 cell, the HP dv1000 with 12 cell and the Compaq V2000 with 12 cell.

If you are outside the U.S., LG offers some laptops with especially long battery life also.

The Sony T series gets at least 6.5 hours of battery life. That's probably stretchable to 7.5-8 if you try.

Look for one with a modular optical drive that can be swapped for a second battery. I know the Toshiba Tecra M and S series, most (if not all) of the Latitude series, several asus (would plural for asus be asi or asuses? Anyway, I know the z70 and w3/z63 do and other probably do as well) and probably most IBM's have this option too. I'm sure there are more as well from HP, Gateway and the others, I just am not familiar with them all.

Saw it in hong kong, nice laptop. Not as cool as the Sony u71 but an excellent comp nonetheless.

"1.2ghz Dolan processor"

They mean Dothan? Or is Dolan celeron.

Are there any machines with at least x600-class graphics that get this sort of battery life?

It seems like there'd be a market for machines that were something like 15.4", decent Turion or P-M, x700 or 6600, 8-8.5 pounds, with a massive 12- or 16-cell battery like some manufacturers put in P4 laptops to try to get them to last for 1:30. You should be able to get some impressive lifetime numbers out of something like that with a more efficient processor.

While it may not be the most elegant engineering solution to have a 5-pound machine with a 3-pound battery, I think it'd sell. The whole weight thing isn't really that much of an issue -- my g/f is tiny and carries her ancient 7.5-pound Compaq everywhere.

With both the standard & modular batteries in and with the CPU undervolted, my Asus Z71v gets around 6 hours battery life with average use. Smilepak can get up to 7 hours with the same setup. And the Z71v weighs less than 7 pounds with both batteries in and has an Nvidia GeForce Go 6600 graphics card.

I am on a thinkpad T42 right now using the 9-cells battery and the optical battery bay. It is giving be a little over 7 hours nicely.

My Asus Z71V with the same setup get around that as well. Ofcourse, I undervoltage and using CHC to handle dynamic settings

HP's NX series notebooks have a second battery available that fits on the bottom and gives you about 9 hours total.

Otherwise, the old Dothan (not Sonoma) Sony S series systems can give you 5.5 hours on the standard battery and 7.5 on the long life battery (I've got one)

So you'd have 2 batteries in the laptop?
