Yes the power switch is called the i/o panel it connects to the system board of the computer by a wire or ribbon cable. You have to unscrew a screw.

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.

SOURCE: I have Dell Optiplex 755

Hi,
The problem of blinking amaber light is usually caused due to a bad power supply on the computer. Open the system tower and reseat the biggest bunch pf cable connected to the motherboard. its titled P1 and it the biggest white connector. If the same doesnot resolve the problem you would have to replace the power supply on the motherboard.

Thanks for using Fixya

Dell Optiplex 755 won't connect to tv?

Computers and televisions do not mix well. The television doesn't understand the computer Operating System and video signal.

Where are fuses located in optiplex 755

The *ONLY* place inside a desktop computer for a fuse would be inside the power-supply unit. Expressed differently, there are *NO* fuses being used.

Dell optiplex 755 no power

You can also have a faulty power supply. I've seen many dells meet their demise with junk power supplies. If you are able, and you have the time, try a different one inside of it. it will need to be about a 300 watt 24 pin ATX style power supply with a 4 or 8 pin CPU power plug. (depends fully on what the board calls for.)

I cant open my dell optiplex 755 cpu cover

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

Dell 755 power light on, fan on after shutdown

Sounds like the power supply is not completely stopping the power after shutdown, Replace the PSU and it should fix the problem. If your problem is still existent then it may very well be the power switch itself. Replace if possible. I Hope this helps.

I got a dell optiplex 755 base unit from work as they were throwing them out but I cannot get a picture on 2 different monitors,no beeps no bios nothing.I connected a key board and mouse (both usb).Unit...

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.
