Reassembled Satellite L300-1DN, now blank screen and no hard drive lights

[Gavin Read]

I have just been restoring a Satellite L300-1DN laptop for someone which has 2 main issues -

1) It was filthy inside
2) It instantly asks for BIOS password upon boot of which is unknown and the standard "Toshiba" does not work, therefore I believe that the BIOS will need to be reset.

I have disassembled it and cleaned it all out and reassembled it again back to how it was. However when I now switch it on although the power and battery lights come on and the fan is working, there is no display nor is there any activity from the hard drive or its lights.

Any thoughts as to the cause of this?

Thanks

Try going in the BIOS, to see if you see something on the screen.

Unfortunately thats the problem, upon boot the screen is blank although you can hear the components working such as the dvd drive reading a disc if one is inserted.

There is no display on an external monitor either.

Thanks

From your observations, your GPU is fried. Because if you have nothing on both screens, the GPU is not doing his job.
