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.

I ran into the same problem with my 7560's all configured with a Xeon Processor.
Once Dell Command Update or SupportAssist upgrades the BIOS (happened to me for 1.8 and 1.10.1), the laptop dies and enters the "try to power on every 22 seconds but only stay alive for .25 seconds" cycle. In this state, MBIST, Power+Fn, Power+M won't work. However, holding D and waiting for the 0.25 second power cycle to try to turn on will trigger the Display Test -- at which point the light blink code will show 2,1 (2 Amber, 1 White) which indicates CPU Failure.
The standard solution offered by Dell is to swap the motherboard. That will work.
However, ifyou can get to the Coin Cell inside and temporarily remove it so that the NVRAM will clear, I found that the laptop was happy again. NOTE: you have to practically disassemble the entire laptop (remove battery, inner frame, heatsink assembly, and enough of the motherboard to get tweezers in) to get there because the coin cell connector cable and port is sandwiched between the motherboard and the keyboard shield -- and there isn't any easy way to get to the connector from any existing holes (top, side, or bottom).
this happened trying to update to the new 1.10.1 also? Is this just running the bios update through Command Update or Support Assist? What if you just download the bios update from the dell support site and then install?
