Thinkpad i Series S30 RAM upgrade

[aglet]

This machine is rated for a maximum of 256MB of memory (see http://www.thinkwiki.org/wiki/Category:S30 and the hardware manual linked from there). However, having had the keyboard off, it appears that the "soldered on" 128MB is in fact in a socket. Could I replace this with something bigger?

Exactly what would I need to buy to get the most out of this machine? The form factor is fantastic, and if I can get more RAM into it, I might replace the hard drive with something bigger/faster while I'm at it... Or is there some form of hardware limit that means 2 * 128MB is the absolute maximum? I took a look at http://www.crucial.com/uk/ and they didn't list the model (presumably because it was Far East only).

I had the lid off to reset a forgotten BIOS power-on password -- remove the 5 screws marked with >> on the underside, carefully unplug the keyboard, and short jumper JP1 (under the plastic cover more-or-less in the centre of the logic board).

The only thing I miss on the computer (besides it feeling a bit sluggis due to RAM starvation) is a "normal" serial port for using it as a terminal. Highly recommended if you can manage to acquire one.

You mention in a post in a different thread that you have a slow hard drive. I'd replace that and see what happens. Upgrading your hard drive to a nicer model with at least 8mb cache and 5400rpm or 7200rpm spin speed will make more difference than you'd think.

Yes, there is. Since the chipset of S30 is 440MX, there is no way you can put more than 256MB.
