I've had to do this for several of these laptops now so I thought I'd just make a picture tutorial to explain. It's been pretty much the same for all models T60 and greater. What we've been doing is upgrading machines with either 1 or 2GB up to 4GB. The memory is located under the touchpad on the front panel, which is removable via long screws on the bottom. All you need is a philips head precision screwdriver and your new ram, which must be compatible with the machine.
