Hi just picked up what I thought was a working Dyson total clean SV06. Put it on charge blue light came on for 3 minutes then went out and thought I was lucky and it must already be charged. Pulled trigger blue comes on then goes green and nothing happens. Is this simply a replacement battery job or have a bought a lemon...

went on the dyson site and theres no info to help or even what the green light is for????

thanks in advance
