Is this with mains on, or just with battery?

Check the battery status light click here with the mains adaptor in, as it sounds to me as though the battery may not be charging (duff adaptor or problem with the socket on the laptop.).

remove the battery and try it just on mains, if that does not work, remove the hard drive from bottom of pc then see if it will boot to show anything

first - its a 640m sorry not a 6400

when I switch it on the mains light in hinge on right comes on and also the battery light.
Of the three "padlock" icons in the section next to the keyboard on/off switch at top, the far left stays on all the time while the other two blink. After about 20seconds all lights go off
the mains adaptor is plugged in and the light on the transformer is showing.

I have tried removing battery - no difference
how do I remove the hard drive

Under a Plat at the bottom of Laptop most likely two screws, it could also be on one of the edges
