When I turned on my laptop, the usual blue Dell logo screen (with press F2 to enter setup) came up followed by a blank screen where the cursor is at the top left flashing, the hard disk light is permanently on and it stays like that indefinitely. When I press F2 for setup, it won't go to setup.
A friend removed the hard disk, memory and battery (individually) and the same happens.
Any ideas what the problem is??
