My dc 10 handheld will not switch on?

I have bought a dyson dc 30 when I first bought it I charged it as per the instructions, after switching it on I found it only worked for a few seconds before switching itself off .
After reading the instructions again I found out why, so I left it for a while to warm up to room temperature & tried it again, but found that the same thing happened. In its present state it will not work at all
