A possible BIOS failure has occurred; the computer is in the recovery mode

Run the BIOS Recovery utility, wait for recovery completion, and then restart the computer.

where as the solid orange light says
The Dell Diagnostics is running a test, or a device on the system board may be faulty or incorrectly installed.

Hello,

High fan speed indicates the system is overheating and the motherboard is speeding up the fans trying to keep cool. You problem now sounds like either the power supply or the motherboard was damaged because of the heat. The GX270 and GX280 system are plagued with this problem. The fan in the power supply goes out or does not spin fast enough to cool the system. When this happens parts called capacitors over heat and can pop. Go to my web site at :
www.ccl-la.com/badcaps.htm

Look at the pictures and open your computer case and check your motherboard. If you see any capacitors that look like the one on my site then your board will need to be repaired or replaced. The bottom 2 pictures are from the Dell GX270 and GX280 motherboards. Also while you have your case open try to power up your computer and see if the power supply fan spins, if it does not spin then you will need to replace it.

I hope this helps,

Check that batteries are charged and installed properly.--make sure driver disc is installed if applicable- check instructions as some wireless suites need you to push a small connect button to initialise them . Also try shifting the usb conector into another USB port if it is notm getting reconised.

Dell Optiplex GX280 - On power ON , no Fan movement no display


Confirm no leaking or bulging capacitors on your mothboard.
refer to here
http://en.wikipedia.org/wiki/Capacitor_plague

As this was a common problem with the GX280.
If found, you will need to replace the capacitors.

The other check is to make sure the heatsink is fitted correctly, perhaps reaply the thermal paste if you have any. I know that high temps would switch the GX280 off.

Same problem... orange power light, fan starts slow and builds up to very high speed.
I removed my video card and SIMMs --> it beeped on boot and the fan did not speed up.
Put one SIMM back in --> booted fine, pressed F2 to view BIOS. Memory reported fine.
Put all SIMMs back in --> all fine now.

Can't load os do you computer Dell only has usb ports


Ensure the Keyboard and mouse are connected to the USB ports nearest the PS2 port on the back of the chassis.

Boot to the BIOS F2 and ensure USB emulation is ON.

If you can't access the bios, reset the BIOS using the Jumper on the motherboard, then USB ports should then work.
