Why when I push the power-on button does my Dell XPS 1530 display nothing on the screen, make a noise of the HDD going, have the caps lock and scroll lock lights on and the num lock flashing – and then not do anything but hum at me ?
(Yes, I have tried pushing F12 on startup, and power-on plus Function, and toggling the media-centre button, and asking Aunty Google)
Without being able to have a fiddle, I would say it’s a hardware issue and it’s time to budget for a new laptop. I’ve had similar issues (although with desktop computers) when either the CPU or a critical motherboard component has given up the ghost.
