Double check that the original memory is correctly seated in its retainers.
If a RAM stick is even slightly off it will cause the symptoms you are experiencing. Some are more fiddly than others but a loose module will prevent the system from starting.

If you can get into the system BIOS, try enabling 'failsafe' or 'default' settings. I'm guessing that mabey the memory timings have been altered.

Also, does your laptop use dual chanell DDR memory, because if it does then the modules will need to be installed as matched pairs.

Unfortunatley the laptop does not display an image or anything responsive apart the power light,

is there a way to reset the cmos on this laptop?

i am not sure if it uses dual channel, but we have put the originals back in anyhow.
