Question about Dell OPTIPLEX 745 PC Desktop

1 Answer

I have a Dell Optiplex 745 desktop computer and now it does not work!

Hi! My problem is that I had to move to Europe and I brought my computer with me. I plugged it to the wall socket and then a split second a pop sound and the computer does not work at all. I admit I did forget to flip the switch on the back, I was on a rush to get things packed as quickly as possible. And I totaly forgot about that and I forgot to look on the back to see. What's wrong and what can I do? Does it have fuses and where are they? Please can you help me?

You have fried your power supply. If you are lucky, that is all you have done but when it blew, there is a chance it sent a surge that also damaged the motherboard or some other component.

SOURCE: Dell Optiplex Power-on Problem

An Amber or Yellow power button means that the power supply is receiving power from the source but is unable to properly distribute it to the components. This can be caused by a defective power supply or a defective motherboard. Just to make sure that nothing else is causing the problem, remove any PCI cards like modem, video card, sound card, etc...
Look at the USB ports to see if any are damaged.

SOURCE: My Dell Optiplex 745 "No Boot Device Available"

No boot device means that the computer cannot find a drive that has a operating system files and therefore cannot boot up.
This usually means that the hard drive in the computer is faulty.
You need to get a new hard drive and install Windows on the hard drive, together with the drivers for the computer's installed devices and programs to get a working computer.

My dell desktop asking for a password


If you want to create a new Basic Input/Output System (BIOS) password on a Dell Optiplex 745, reset the password. Resetting the password also applies if you want to remove an existing BIOS password. BIOS passwords are used to add an additional level of security to your machine. Without the correct BIOS password, your Dell Optiplex 745 will not complete the boot process. The password can be reset whether you know your current password or not.

Turn off your Dell Optiplex 745. Start the computer. Press "F2" the moment the Dell logo appears on the screen. You will only have two to three seconds to press the key. Enter your BIOS password. Navigate to the "Exit" screen. Select the "BIOS Password" setting. Enter your BIOS password and a new password if desired. Do not enter anything in the "New Password" box if you want to remove the BIOS password completely. Press "Enter" to save your password settings. Reset Forgotten Passwords Turn off your Dell Optiplex 745 and remove the power cord from the computer. Disconnect any external hardware and cables. Slide the release latch located on the back of your Optiplex 745. Lift the cover as you slide the latch. Hold the cover firmly and pivot it back on the hinges. Remove the cover from the hinges. Find the "PSWD" jumper on the motherboard. This is a two-pin jumper and should be clearly labeled. Use a flashlight and magnifying glass if you have trouble locating it. Remove the jumper from the motherboard. Replace the cover and slide it into place until the latch snaps into place. Reconnect the power cable and restart your computer. Shut down the computer after it has completely restarted. Disconnect all cables and remove the cover again. Replace the PSWD jumper. Replace the cover. Reconnect all cables and restart your computer.
