Decided the laptop could do with more memory.
It can support up to 4 gig (had 1 gig), but 32 bit windows can recognise 3gig.
Ordered it from crucial, got the exact spec and a matched pair as well by using the details on their website. Laptops are muh more piccy in memory than home build desktops.
Took out the 2x512meg modules and fitted 2 x 2gig modules.
Not as easy as updating normal pc memory, getting the covers off under the bottom is a bit fiddly, but the operation worked.
Certainly runs faster but it will show more with memory hungry apps.
I now have a pair of Samsung 512meg SODIMMS without a home :(
