Try Starting it just on Mains, take the battery out

Remve the Hard Drive in bottom most likely under a Plate then see if you can get anything on screen

Remove battery and the power supply. Press and hold the power button for 30 seconds to a minute. Now try with the power supply only - no battery.

tried that Taff, nothing mate, same makes a werrrr sound of the fan blue power light comes on but screen remains black

removed hard drive, still the same

Could the screen have failed? Try an external monitor perhaps. When the computer attempts to power up is there any hard drive activity that continues even though you can`t see anything?

screen worked last night when it did work once
have another laptop but dont know how to link up, no hard drive activity , fan goes for 5 seconds then stops

You would need an external monitor not the laptop but the lack of HDD activity more or less suggests it`s not a screen problem. The computer isn`t even getting to the POST which is bad news. This suggests to me that it is a motherboard problem. What make and model; is the laptop and how old is it?
