Aspire V3-772G (VA73) - Flash BIOS?
Hi
I have turned on this computer after some time of it being unused. The power
light comes on and the fan starts but nothing appears on screen. It flashes
very slightly (almost unnoticeable) around once every 30 seconds or so but not
enough to see anything.
I have tried plugging it into an HDMI monitor and it registers power, but there
is no signal.
My understanding is that I need to flash the BIOS using USB (ExFAT) with the
latest .fd file on it (I d/l this from ACER and took it from the .exe file).
My understanding is that then I needed to insert the usb stick into the laptop
(whilst it was off), press FN+Esc and plug in the power cable and then press
the power button. Everything on the web tells me that after around seven
seconds the power button should flash, but mine does not. It just sits there. I
have also tried the following:
1. Holding down Fn+Esc for a full ten minutes after pressing power button -
still nothing
2. Replacing CMOS battery - still nothing
3. Replacing normal battery - nothing
4. Holding in the power button when turning it on (and holding Fn+Esc) - all
that happens here is that the laptop powers off
5. Unplugging battery and power and holding down power button for 30 seconds to "flush" any residual power out of system
Based on what I have read (which could be complete rubbish), I could try to
trip the CMOS? But I do not know where the CMOS jumper is on the motherboard
and cannot find any manuals for this.
Please can you tell me the following:
1. Does this motherboard (I believe its NBM7411001) support the BIOS
"Fn+Esc" utility?
2. If so, what is the correct method and why would mine not be working?
3. After downloading the files and unpacking the .exe file, which files exactly
should be on the USB stick? I have tried with all files (at root), with just
the .fd file and Flashit.exe, and then with just the .fd file - none seem to
work
4. What should I rename the isflash.fd file to? I have tried zg5ia32.fd and
VA70HWX64.fd - again neither works for me.
5. Where is the BIOS chip on this motherboard? In case this is just completely
messed up and therefore I have to replace chip?
I'm not massively computer savvy and do not mess with the BIOS on my machines
so not sure how this happened in the first place, I can only assume the main
battery ran out and then the CMOS battery died too whilst it was unused.
Any help you can provide would be appreciated.
Please note I have asked the same question to Acer support so will report back if they give me anything useful.
Many thanks
