SP515-51GN Bios recovery procedure
Hi,
I have recently updated the bios on my acer SP515-51GN. During the update procedure, the computer randomly shut down and
I was never able to have display after.
The computer stils powers up, and the keyboard backlight works.
I have tried many things just to make sure that the bios was really the problem, including:
Trying an external display with the hdmi port,
hard reset,
bios battery test,
removing unecessary components like the hard drive, etc...
I then tried to recover the bios...
I am aware of the FN + ESC key to start the recovery process from a usb key.
I first downloaded the latest bios version from the official Acer website, extracted the .fd file from the .exe
I then formatted in Fat32 an old 2Gb usb key i had, and proceeded to put the .fd file on it.
I shut down the laptop completely, and powered it on while maintaining the FN + ESC keys.
The recovery process seems to start because the usb key flashes for a few seconds, but after about thirty seconds the laptop just reboots and
nothing happens, even after thirty minutes.
I then tried a combination of the following things while doing the recovery process:
I have gone through many pages on this forum with similar problems, trying every solution offered.
I tried all the bios versions released on the acer website.
I tried all the usb ports for the recovery process.
I tried doing the recovery process with the battery unplugged.
I tried renaming the .fd file with multiple names.
But nothing seems to work.
Can you please point me to the correct procedure to recover my bios ?
If need be, I can solder a new bios chip on it, but I havent found the right chip with the
bios pre-installed on it (I have found empty chips, but do not wish to install one, as I fear it will not solve my problem).
Thank you really much,
