Acer :: Add RAM To Extensa 4620-6456

I got this laptop for my father-in-law. He's a lite user, and XP was a better choice (he's not quick to adapt to new things and he doesn't need to re-learn on Vista)

Anyhow, the 4620 was what we picked out.

Current config:

Core2Duo T5600
1GB RAM (1 stick of 1gb/PC5300 DDR2)

Desired Config:

Add 1GB Ram (second stick of 1GB/PC5300)

I opened the bottom of the case and found the 1 stick. It is in a bay labeled "DIMM 1"

All the research I can find says there's a second DIMM slot (DIMM 2) but I cannot locate where this on the laptop.

I have removed the HDD, and the slot is not below it. I have (painfully) removed the keyboard, thinking the slot would possibly be there (like it is on Dell units)... and there is nothing under the keyboard either.

The Acer manuals don't have anything about self-maintenance/support, so now I'm here.

Reading through, I'm sure someone else has done this, and maybe it's so obvious to everyone else no one has explicitly said "oh, by the way, to get to DIMM 2, it's _here_"
