Here's some food for thought, I'm a firm believer of "maxing" out the
machine, no matter if it is a laptop or desktop, just max it out. All mother
boards have a limit of supported memory, and right now, most memory is
relatively inexpensive so why not? If there is anything slowing down your
machine, then you know it's not a memory issue and time to look for running
processes.
Just my humble opinion, and best of luck to you.

What's the largest memory module you can stick in a slot?  512 MByte?

The reason I ask is you didn't mention a specific model # (or I missed
it in earlier messages).

I have a Toshiba Satellite 1905 S-303, P4, 2.4 GHz and recently upgraded
its memory.  It too has two slots and originally had a total of 512
Mbytes (2 256 MByte mem modules).  It currently runs XP on it.  I've
been thinking of toying with Vista and read where the min mem for Vista
is 1 GByte, so I thought "No, big deal.  I can jump up there."  Well, I
was right, but on in the sense, I could bump the max mem to 1 GBytes - 2
slots of 512 Mbytes and no further.  So I recommend you double check
your laptop's spec's.  I'm not saying, you can't, but I don't think you
really want to order a 1GByte mem module and find out your laptop's slot
can't handle it.

Good luck.
