My Acer AO532h-2588 notebook PC boots fine as far as
the BIOS screen, but no longer boots my Windows10 OS from the internal hard
drive or from an external bootable USB drive.
After the BIOS screen, the display goes black. A quick web search showed that to be a common problem with this
model.
Many
help sites recommend re-flashing the BIOS.
I attempted to do that but can't get it to work. Here are the steps I followed:
1. On a separate, working PC, partition a USB drive to
4GB so it can be formatted with FAT
2. Download the latest BIOS from the Acer website
(v1.26) and use the DOS files, not the Windows files, since the Windows OS is
not working on my notebook PC. Rename
the BIOS file to ZG5IA32.FD and place a copy of it and
the FLASHIT.EXE and FLASH.BAT files on the FAT-formatted USB drive
3. Move the USB drive to the malfunctioning Acer
PC, hold down the Fn and Esc keys, and press the power button. Release the Fn and Esc keys after 5-10
seconds and the power button light will be blinking
(Failure mode: the power light on my Acer PC
never starts blinking. A few seconds
later, the BIOS screen appears as usual, showing the old BIOS (v1.21), and then
the screen goes black)
4. Had the power light began blinking, I was
supposed to press the power button once to start flashing the new BIOS, and the
new BIOS was supposed to be installed within a few minutes
I can’t get the power button light to blink, so the
BIOS does not update. I tried two USB
drives and neither works. What am I
doing wrong? Did I load the USB
improperly? --I simply formatted it to FAT and then copied and pasted the
downloaded files to the USB drive.
