How to recover bios on OLD Dell
How to recover bios on OLD Dell
I have an old Dell Optiplex 7010 that I was planning on turning into a NAS. It was working fine, however something apparently went wrong when I tried to swap out the hard drive and now it won't post. I've tried everything for a no-post situation, I've got just one stick of ram and the cpu and cooler attached, but it gets no video output. I'm quite certain that it's a corrupted BIOS, but I can't find any info on how to recover the BIOS on this generation of machine, everything on Dell's website is for machines shipped after 2015. It has two jumpers that I can see, one labeled PSWD and one labeled Service Mode, but they don't seem to help. Booting while holding Ctrl + Esc doesn't help either. If anyone happens to know how to flash a new BIOS on one of these, please let me know!
is there a tiny coin cell on the motherboard? most consumer boards use a cr2032 battery to power the chip where the BIOS data is stored. if you take it out, let it sit for a few minutes, then put it back, the BIOS settings should reset and any issues might be fixed.
You can simply remove the CMOS battery to restart it. Refreshing isn't typically required with DELL products. Verify all your connections. Changing the drive shouldn't have affected things. Do you have a post speaker that beeps?
