Dell GX280 boards

Thanks for replying. Can't flash the bios as machine wont boot and bios IC is soldered to the board. I have processed about 200 of these units in the last month and have a known good test bed. I think it may be to do with the board not sensing PSU voltages correctly on switch on - I am still working on it.

Dell are not very forth coming with any info, here in the uk. The boards are all the same made by foxconn Various Dell p/n's CG815 / DG389 / G8310 ... etc but all the same thing.

Any help you can give would be appreciated

Dell gx280 wont boot


The power supply might be defective, but usually this means a bad system board. Any other kinds of problems would allow the system to at least boot, but this one isn't getting even that far.

Unfortunately, the Dell case uses a proprietary motherboard, so you will need to get the same one if you want to replace it.

Startup no beep, bios defective...how to replace bios then...


Hi,
you would usually flash/update the old bios, with the new bios via floppy disk drive, or cd if your motherboard supports it. if you go to the manufacturers web-site-support or downloads. you should be able to get the latest bios for the board. also read any notes on " flashing the bios " if the board won,t boot, you can,t damage it anymore than it already is. nothing to lose everything to gain.
if you have to send the board to be unsoldered/re-soldered very expensive usually.

if this information solves your problem, please rate as Fixya.

Many thanks for using the forums.

Mike @ compurepair.

Dell GX 280 wont start


An Amber blinking power button indicates a low voltage problem. 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... Remove the memory modules and disconnect cables to CD/DVD drives. Look at the USB ports to see if any are damaged.

Motherboard


Well it sounds like the BIOS doesn't detect the hard drive any more. Viruses typically don't get transfered to the mother board/ BIOS itself. They usually are only on the OS. Unless someone flashed the BIOS with the wrong version or something. If that is the case it's either trashed or you need to find the correct patch to flash the BIOS. If this is not the case boot into the BIOS and configure it to see the hard drive.
