Precision 7560 BIOS update bricked
Hi,
I have a brand new Precision 7560 (XEON/512GB HDD/32GB) out of the box, ran through Windows updates as part of set up process and identified urgent BIOS update to 1.5.0 (I believe). Laptop restarted and completed Updating Firmware process (Flash Progress reach 100%) - but machine will now not boot.
Pressing power button, the power light comes on for 3 seconds then turns off. Holding down the power button results in power light staying on for 15 seconds, but turns off again. During this period the screen remains completely off.
Have tried plugging in external monitor, booting with battery disconnected and using only AC power, also tried F2 and F12, as well as Boot Recovery (Ctrl + Esc) but laptop appears completely bricked.
Machine purchased through ERP and associated corporate Dell Premium subscription, but no immediate solution has been offered. Loathed to replace the machine as lead time to get shipped for this one was 8 months.
Very grateful in advance for any advice. Thanks.

Nope. Its the exact same issue as last time. I even went as far last time as removing cmos battery. Not going that far this time though. I can’t believe dell has rereleased this bios back into the wild.

Sorry for slightly unrelated topic, my Precision 7560 experienced brick after making bios settings which seem to be safe. Therefore, I requested the motherboard twice for this reason in past. As the time I write this reply, my Precision 7560 currently run good as normal.
I was unable to boot into OS and even entered BIOS, except keyboard backlit blinked twice and system status light blinked twice, and then turned off and turn on again. The only thing my bricked Precision 7560 could do was LCD BIST Test. I thought that it was caused by CPU failure, but I was not sure.
I remembered that I made change in BIOS so far before bricking my laptop:
1. Enable powershare
2. Enable intrusion detection
When I changed BIOS setting before bricked the laptop, I connected two hard drive though USB ports (one type-c and one USB type-A with powershare)

Part replacement is not enough because Dell engineer need to investigate the bricked motherboard for the root causes to avoid same problem happened again

Dell needs to investigate these BIOS update problems!

We've now had this happen roughly 8 times with 6 Precision 7560's. Each requiring a board replacement. I Just received a new 7560 today for another employee. This time I decided to touch NOTHING and just run the BIOS update. It updated from 1.12 to 1.15.2 perfectly. On all the other ones we received from CDW we made some standard BIOS changes to support our companies needs. I'd be willing to bet my next paycheck that one of those changes prior to the BIOS update is the cause. The two main ones that we change is USB Powershare = ON, and we always disable/nuke the Absolute chip.

The "disable/nuke the Absolute chip" is that this setting here:
Enable Capsule Firmware Updates" in the bios. It is under the "Update Recovery" Section?
I just disabled that on my 7760 since windows update updated my bios from 1.14.0 to 1.5.2.
I am wondering if I should enable it before running future bios updates. 1.16.0 was released.

The option I'm talking about is under the Security Section for the Absolute Security chip. You have three options. Enabled, or Disabled, or Permanently Disabled. We always do Perm Disable.
