SOURCE: Dell PC Desktop Optiplex GX260 Doesn't boot

Open up the case and remove any add in cards and memory modules. Try to start up by adding these back one at a time until the unit stops booting normally. The light combination is not one recognised in the user manual so I am guessing you have a non-descript fault with one of your components. Be careful when you open the case as to not disturb the ribbon to the motherboard which controls the power, I have had a very long experience trying to get one of these reconnected!

SOURCE: Dell OptiPlex GX520 PC Desktop Problem

Hello everyone, check your cpu - I've just had one of these in for repair and the cpu was faulty - removing the ATX 4way 12v lead let the pc start rather then detecting a short and shutting the psu down. Changing the cpu cured the fault.

Thanks

Why is dell optiplex 780 lights 1 & 3 ok and power button amber?


An Amber blinking power button indicates a low voltage problem. This can be caused by a defective power supply or a defective motherboard.
Remove any PCI cards like modem, video card, sound card, etc... Remove the memory modules and disconnect cables to CD/DVD drives. Look at the USB ports to see if any are damaged.

Is there an SD card slot on the Dell OPTIPLEX 780?


There is no card reader on most models of the Optiplex 780. There may be a card reader on the SFF unit. The MT, desktop and USFF do not include a card reader. You can add a 3.5" internal card reader to the MT or desktop models for under $20. You could use an external USB card reader with any Optiplex 780.

I hope this helps.

How can you reset the cmos password


Dell Optiplex 780, user forgot BIOS master password (which is necessary to change the boot order to run BartPE from CD and do an image backup).

There is a jumper on the mainboard called PSWD1, which is set (shorted). Remove power cable from PC (CMOS battery can stay in place), open the lid. Remove jumper from PSWD1. Reconnect power, start the PC, hit F2 to enter BIOS. All passwords should be reset.

Leave BIOS, power off the PC, remove power cable. Reattach jumper to PSWD1, close lid, reattach power cable. Start PC. Enjoy.
