Hi

Try and google your model and make of the laptop to see if other owners encountered the same problem and how they resolved it.


there should be a lever on the side of the cpu that unlocks the cpu so you can remove it


cheers

SOURCE: the OPTIPLEX 755 will not start

Open the case and look at the little black round things that look like soda cans. Those are called Capacitors. they are kinda like small batteries. They should have a shiny silver top. If they have anything oozing out or if they look like theyve popped like a popcorn kernel, then you have a faulty board. If your pc is under warranty, call dell asap. its an easy repair and its done the next day.

I recently worked with a couple of used Dell desktops that someone got from work. Sound familiar? I couldn't get them to come on because the plastic bracket that holds down the CPU heatsink was broken. The heatsink was also covered with a carpet of dust. The new owner could've bought a new heatsink/bracket online, but they declined to spend money. Open it up, make sure everything is in order to diagnose the problem.
