Hi I have just acquired a Lenovo T420 laptop PC to replace my older one. Unfortunately it came without a charger/power adapter and it needs a round pin (the "yellow round" type) and my current one is the square type. Before I buy a new one I thought that I would ask if anybody has a Levono power adapter with the round pin to plug into the PC so that I reuse something. I can be flexible on collection and can pick up from anywhere within the M25 as I se public transport to keep my carbon footprint low. Rgds Kevin
