Thanks again for all the replies and advice. 2 x 4GB RAM is on the way (the most a T410 can take as far as I can tell) and I am now also looking at increasing the internal SSD size to 1 or 2TB. When preparing to install a new internal SSD, am I correct in thinking that I just need a USB - SATA cable in addition to the new SSD drive, in order to use software to clone the old drive? I see Crucial have their own cloning software if I purchase a new hard drive from them but is there a better/recommend cloning system to use?
