Desktop 280 G1 mt doesn't start after bios UPDATE

[Moha2]

Hello,

today i downloaded the latest bios version on HP website for the said PC, the file was .exe so i had to install it from windows until it reached a point to reboot; after reboot it went into a screen to choose update bios or update later, i choosed update bios and waited. it rebooted and gave some noise, then it went silent and nothing happened after that. now the pc is not starting up, nothing on the screen.. any suggestions?

Hold down the Windows Key and the B key at the same time. Press the power button and wait for the PC to respond and recover the BIOS.

What's happening is the fans only that works when i press the power button, the monitor and keyboard doesn't show that its receiving any signal, i formatted the harddisk on a different computer. I used your method, i held the Windows Key + B then powered on the computer while am holding it, waited for about 4 minutes and nothing happened. any other suggestions? i should repeat the steps ?

If you formatted the hard disk before using the recovery method I suggested, then that is why it didn't work.

The previous BIOS was in a folder on the hard disk and formatting it removed it form the hard disk. 

The modern UEFI BIOS keeps part of what it needs on the hard disk. Formatting it was not a good thing. 

I will have to see if we can find a version you can put on a usb flash drive to boot to and recover your BIOS.

I am unable to locate a compatible BIOS version that you can put on a USB flashdrive to recover the BIOS.

I recommend that you contact Hewlett Packard Enterprise directly for warranty repair.

Hello,

If any of what I will list below can help, Please Tell me:

1- I still have the original Harddisk, the one i formatted is a harddisk i use for testing operating system.

2- I have another Computer same model and it's working and functioning well.

3- the bios i installed is the bios on the website of HP support drivers and software

Thank you for your support!

Install the original hard disk.

Power the notebook on with the power adapter connbected and then use the Windows key + B key method.

It is a desktop not a notebook.

You still need to install the original hard disk. It has the previous BIOS file.

The 8 beep diagnostic means that there is an invalid ROM detected. That would be the BIOS file in the CMOS chip on the motherboard.  

Which BIOS did you attempt to update to?

The option that may resolve your issue is downloading the  HP PC Hardware Diagnostics UEFI softpaq and making a standalone troubleshooting USB  flash drive with it. Boot to it and use the Firmware Management to rollback to the previous BIOS. Create the standalone troubleshooting USB  flash drive on a different  PC or notebook and then plug it into a port on your 280 G1 and boot to it. The following link is direct to the Hp softpaq that you need.
