I just installed a new harddrive on my Thinkpad X61 Tablet. What Lenovo software should I download and install to ensure my system remains stable and secure, and that I get important updates as they come?
Install 'ThinkVantage System Update'. The program will suggest the updates relevant to your system, and you can pick and choose the relevant software updates you wish to download and install.
You can download ThinkVantage System Update from the Lenovo support site here.
