I bought a 512MB memory card for my IBM laptop over two months ago. I knew my computer had two slots for memory. It had one 512 and one 256. So I was going to change the 256 with my new 512.

When I looked at the back of the laptop (where most of the memories are located at), I found the 512 memory easily, however there was no 256 (there was only one slot).

So I gave up, until today. I opened the laptop hoping to find the other memory slot and replace it. Indeed, I found it hidden under the keyboard (had to completely open the whole thing).

Here are some pictures of the open laptop. I thought to make this post for those who want to change their R50e laptop memory and can not find the second slot:
