                  Dell 9010 MT BIOS Update Always Fails
                  by mikeybass
                  Hi, I hope some one has some advice for me. I searched the forums but didn't see anything relevant. I acquired two identical Dell 9010 Mid Tower computers from a business office upgrade (they were going to throw them out). Both of them have the same motherboard (00F82W). One of them works flawlessly. The other one had a corrupted BIOS. I tried flashing numerous main BIOS and EC files from the internet, but none of them worked. I decided to copy the main BIOS and EC from the working 9010 computer and successfully flashed the corrupted BIOS. This got the computer able to boot again and run norm...

                  Dell Optiplex 7010 micro bad BIOS flash?
                  by mrrubik
                  Hi folks,

                  I got a Dell Optiplex 7010 micro PC (Exact Model) with 8FC8 BIOS and locked out admin password. I attempted to remove the password by patching the BIOS via info from this thread: https://www.badcaps.net/forum/troubl...ssword-patcher
                  After flashing the patched the BIOS, the PC is unresponsive with a solid AMBER power LED (not documented in manual anywhere)

                  Steps I took:
                  1. Read BIOS with CH341a, verified hash twice
                  2. Patched
                  ...

                  Dell Precision T7910 no bios, no post after applying SAS/RAID setup
                  by bmxlovah
                  Hi,

                  My Dell Precision T7910 died after enabling onboard SAS controller and applying RAID settings. There were no hardware changes between working and not working state, only setup (via bios -> controller settings). After applying settings and reboot PC turns on, flash leds (normally) but there's no further action, it just stays on with no graphics and no keyboard led's on. There's no Dell logo, nothing. I've tried resetting bios by jumper, replacing cpu's, replacing ram, removed/replaced cmos battery, disconnecting all drives etc. I've also dumped .bins from mobo chips SLI1 (16...

                  Dell Precision T1650 MT Workstation bricked after BIOS update
                  by trix11
                  I have a Dell Precision T1650 MT workstation (of the following spec.) that was bricked yesterday when attempting to update the BIOS from A27 to A28 per:
                  - https://www.dell.com/support/home/en...-t1650/drivers > Dell Precision T1650 System BIOS

                  - Dell Precision T1650 mid tower Workstation
                  - Xeon E3-1225 V2
                  - 32Gb PC3-12800E RAM
                  - 4Tb SATA HDD
                  - motherboard: Dell part: 0C3YXR CN-0C3YXR-72200-39C-01GR-A02

                  I see now that others have experienced like issues e.g.:

                  Dell G5 SE 5505 - "Invalid memory installed" after BIOS update.
                  by lalle-
                  Hello!

                  I have a problem with a Dell G5 SE 5505 laptop that I hope someone can give me a few pointers on.
                  [OK, it's not really a laptop, I'm running the motherboard on my desktop with only cooling, RAM and an M2 drive attached.]
                  I had some performance issues, so I decided to update my BIOS from 1.7.0 to the latest version, 1.20.0.
                  The computer restarted and the update dit not want to continue without a battery connected, even though I used dell's method of bypassing this requirement.
                  I tried updating to a custom BIOS from Reddit user Satori_Nori https://www...
