Dell inspiron turns on,fan keeps turning,but screen does not power up,Display does not power up,checked hard disk,Ram. all fine ,BUT !!!!!
Previously the laptop would keep on once rebooted if screen brightness was reduced just after the boot,else screen would go off and probably the laptop too..
Later troubleshooted with a different adapter and it would boot but not with decreased screen brightness..
IS THE ISSUE WITH THE DISPLAY OR ADAPTER?
 
Try this...

1. Turn the laptop off (not sleep or hibernate but off).
2. Connect an external monitor to the laptop.
3. Turn on the external monitor.
4. Turn on the laptop.

NOTE: You may have to press an "external monitor" button. Could be the f4 button or a button with two monitors on it, for the external monitor to work.

If you can see fine on the external monitor, then your attached display, or the ribbon cable that connects it, are your problem.

If you can't see on the external monitor at all, or the problem occurs on the external monitor as well, then it is probably the graphics card/GPU that is the problem, which may require the motherboard be replaced.
