More memory for Sony Vaio

Archived from groups: comp.sys.laptops (More info?)

My Sony Vaio PCG-941C now about 4 yrs old) has a listed maximum memory
of 256Mb. I've tried putting 256Mb in one of the slots but it only
sees 128Mb. Anyone aware of a way to exceed the specification?

Cheers

Steve

Thanks Rik. The memory I ended up with, 2 x 128 144 Pin SODIMMs at
100Mhz, which is what Sony specify. More than likely, it's the way
Sony have wired the thing so I'm stuck with it until I can afford a new
laptop. Cheers Steve.
