Acer Aspire VN7-591G BIOS recovery

[sharky_25]

Hello to everybody,

I have an Acer aspire VN7-591G. Yesterday I followed the suggestion from this forum to unlock the advanced page of the BIOS. The process worked fine, using the command line method and changing the Intel page value to 0x1 did the trick. But now my notebook is not posting.

After changing of the settings the notebook posted, but I went into the BIOS and removed the BIOS password and enabled secure boot, saved the changes and my notebook does not post at all. It turns on, I can see the backlight on the keyboard but the screen does not turn on. After a while, the fans also start to spin slowly but no POST, nothing.

Can anybody help me. Is there a method to reset the BIOS settings to default? Or to reflash the BIOS.

I tried the recovery mode. I used the BIOS file from the latest BIOS which I named it as HadesSX64.fd and put it on a 16GB USB drive which is formatted as FAT32. I tried to hold FN+ESC, and plug in the USB and then press the power button, but the USB drive flashes 2-3 times and that's all, the fans don't come on (just after a while) and nothing happens, the USB drive it's not accessed anymore (no flashing of the LED).  I tried this method with the battery disconnected but the result was the same.

Can anybody help me, to tell me what I am doing wrong? I really need the files from this notebook for Monday, and unfortunately I don't have any other machine with an M.2 slot to take the files.

Thank you very much,

PS: the latest BIOS can be found here: https://global-download.acer.com/GDFiles...ER&SC=PA_6

Hi. I recently managed to brick my laptop by changing some options in "advanced menu" in BIOS. The options that I've changed had something to do with power management which made (probably) system unstable and as a result bricked laptop. Why do I think it's bricked? Laptop starts up but screen is not showing even on external monitor. Things that I tried already: -removing CMOS battery, -checked RAM memory, -flashing BIOS from usb. Nothing helped in that case. Bios downloaded and installed from here. It's 1.15 version. Is there someone that could help me with this? I've heard about programmer for BIOS, I could buy it but have no idea what to do with a code that i'll get.
