I did not quite understand you...your laptop bricks?
Are you sure that this is not a hardware problem?

It is turning on ( power led on black screen) after several on / off it's going.
But i resolved myself. Just had to rename file to ZQN.fd and make the recovery process and now all works fine.

Thanks for Reply.

Good evening from Italy,
I have an Acer Aspire E5-721-63XD that does not start. Black screen.

I already check hard disk, ram and I tried to disconnect battery for more than 4h. But nothing changed.

Reading in this forum I tried the procedure FN + ESC + POWER ON, I connected a FAT32 USB with the BIOS files (zqnbiosR.fd, InsydeFlash.exe, ecc...)  downloaded and unpacked from the Acer site. The procedure starts and the blue LED flashes, blinks for more than 45min without ever restarting or solving the problem. The screen is always black.

Please Help! Thanks!

Me too i have a ACER E5-721-641S that won't boot.  I downloaded version 1.07 from Acer but it is a windows program so how can i update the bios without the computer screen?  The hard drive start for a minute and goes out.  The blue on led stays on forever.  The charging led is blue too.  The screen backlight fired up but the screen stays black.

Thanks
