I ordered a "build to order" notebook from HP, the ZE4500, which I should recieve in a few weeks. Rather than have HP add addional memory, I just ordered it with standard 1x256 memory, planning to add my own memory. The basic system specs are;

XP-M 2400+ (has the 512 cache, so I think it must be a Barton)
ATI Mobility Radeon 7000 (up to 64m shared memory)
54g wireless lan
dvd/cdrw
15" TFT XGA
60g 4200 HD
memory capacity is 2 sticks of 200 pin, up to 1g total DDR sdram, 266 FSB

OS is XP home, and hope to dual boot to Mandrake Linux 9.2 (hence the big HD)

Question, What is the ideal type (2100/2600), brand (or chipset), amount, and configuration of memory for this laptop? Also is memory a significant factor in battery life (say for a gig)? I'm really more curious about whats optimal, and less concerned about cost. Any opinions would be appreciated.

well, since all Mobile Athlon XPs run a 266MHz FSB, you don't have to get PC2700 - PC2100 should be fine to run synch with the FSB. You could also run PC2700 at PC2100-speeds with a lower latency(if your BIOS supports adjustment of ram-timings).
It depends on your chipset - i have seen some Laptops with a VIA KT333 -chipset...in that case, PC2700 could provide some additional performance. If you could tell me your laptops' chipset, i'll try to find out if it supports PC2700. you could also look at the stick that came with it - if thats PC2700 you should get PC2700 for your upgrade.

oh yeah, if you add another stick to the one that is already in your laptop, it MAKES NO SENSE getting PC2700 if the existing stick is PC2100(because the faster stick will ALWAYS be limited to the slower sticks' speed)

It shouldn't affect battery life very much(if at all) IMO, whether you have one stick of ram or two.

uh..i hope this helps a bit...sorry if it's somewhat confusing

I don't have the laptop in my hands yet, but I'm sure it will ship with DDR2100. Being a laptop its hard to get official info on it for things like the chipset. I have been told that it has a ATI IGP320M northbridge. I was considering geting a gig of PC2700, cause it's still cheaper than having HP add 1 stick of 512m PC2100 to the standard 256m. My thought was that the 2700 might be more useful to have for a future laptop, but I've really have never dealt with "shared memory" before (this is my first laptop, and first factory computer), so I don't know if there are compatibilty issues with PC2700. Its kind of funny that the Radeon 7000 is a native 333 graphics chip, and the Barton core is native 333, but the laptop is limited to 266.
Thank you for the info,

there won't be compatibility issues with PC2700 and the shared mem gfx.
The IGP320M supports only PC2100, AFAIK(it's a it hard to get info on it, but i'm pretty sure it's correct).

As all DDR-SDRAM is backward compatible, you won't have any problems running PC2700 - it will simply run at PC2100-speed and that's it(as i've said before, you can reduce latencies a bit if your BIOS supports changing RAM-timings)
