Turn it all the way off, wait 15 or so seconds then turn it back on. As soon as you see the Dell logo, press [F12] immediately then select "Diagnostics" from the boot menu and press [Enter]. If you see a message stating that no diagnostics utility partition has been found, run the Dell Diagnostics from your "Drivers and Utilities" CD/DVD.

I can't, the screen is completely black from the start. I can hear the laptop start up then it just like stops. I can hear the fan spinning and the disc drive spinning but everything else is unresponsive.

Hi, the leds point to a memory problem, try reseating & make sure that they are fully seated. This link gives the led codes & should be the same for your 1525.
