144-pin, 256MB PC100 SODIMM memory is widely available. Crucial, Kingston, Viking, IBM and Sony all sell that part. Prices range from $59 on sale to $175 or more new. It is not cheap.

Thank you. I was able to add another stick of 128MB but now some of the keys are acting up. What should I do?

I was wondering if some can help me figure out how to change the memory of Sony Vaio PCG-862A. I tried opening couple of slots in the back but couldn't find one for Memory. I currently have 128MB Chip and I know it supports upto 256MB.

A laptop or notebook is a portable personal computer with a clamshell form factor, suitable for mobile use. Although originally there was a distinction between laptops and notebooks, the former being bigger and heavier than the latter, there is often no longer any difference. Laptops are commonly used in a variety of settings, such as at work, in education, and for personal multimedia. A laptop combines the components, inputs, outputs and capabilities of a desktop computer, including the display screen, speakers, a keyboard, and pointing devices (such as a touchpad or trackpad) into a single unit. The device can be powered either from a rechargeable battery or by mains electricity from an AC adapter.
