Hello,
I have an HP ZBook 15 G3, with a motherboard model number APW50 LA-C381P REV 1B (dated 2017-03-29).
When I start it up, the LEDs light up, the fans spin, and the keyboard backlight comes on then goes off, but the screen remains black. What could be the problem?
I've attached a dump of the three chips (16MB, 8MB, and 1MB).
Thank you in advance for your help.

Thank you,

I flashed the file into the 16MB chip, but now the computer's behavior has completely changed .
As soon as I plug in the power adapter, the power on-off button light, the Caps Lock key light, and the charging indicator light all flash continuously, as the video I posted.
And this time, the fans aren't spinning, and I still have a black screen.

Is this file the clean version of the ME? If not, could you send me a version of this file with the clean ME version please?
