I would really appreciate it if you be kind and help me. I just got my new Acer Nitro 5 this past Sunday. I did the initial battery charging cycle three times while the standard heavy Windows Update was working in the background. For the first couple of days it worked nice and I could do some urgent work in Excel and had no time for installing many other programs or games.
On Wednesday I decided to plug a mouse to better work on my spreadsheet but found it didn't work on any of the three USB ports (very dim and blinking "laser" sensor). I uninstalled and reinstalled the standard USB mouse driver but couldn't get my mouse to work. So, I thought I would take a look at the BIOS setup to see if I could see anything wrong in my USB ports settings (I am no expert but I just wanted to check) so I went to Settings -> Update&Security -> Recovery -> RestartNow -> Troubleshoot -> AdvancedOptions -> UEFIFirmwareSettings -> Restart.
It actually took like 5 minutes for the BIOS menu to show and I did notice immediately that the BIOS menu navigation was very sluggish. I didn't see anything out of the usual (even though this UEFI thing is new to me) and decided to exit without saving. And BOOM I got the BLACK SCREEN! (keyboard lights on). I turned the laptop off and on and always got stuck in the black screen and no Acer logo pops up. The keyboard lights are always on.
And I have been stuck like that for three days. I have read literally hundreds of forum messages trying to solve this issue. What I have done so far:
1. No pinhole battery reset does anything: pressing the battery reset button for 4,10, 40 seconds, waiting for 5 minutes, plugging it, powering it up again I get the black screen all the time,
2. I have taken the RAM stick out and replaced, even carefully scrubbing the pins with a pencil eraser,
3.1. I have after much research found the isflash.bin file hidden in the temp directory (for both BIOS v1.15 and v1.19),
3.2. I have used the Phoenix tool to try to find the appropriate name to rename the isflash.bin, but that goes beyond my skills,
3.3. I have renamed the isflash.bin (both the v1.15 and v1.19) in numerous alternatives: C5PRHx64.fd, AA.bin, AAHW.bin, BB.bin, BBHW.bin, C5PRHx64.bin, isflash.bin, AA.fd, AAHW.fd, BB.fd, BBHW.fd, BIOS.fd, BIOS.bin (main file extracted from downloaded .zip from Acer's webpage: C5PRH119.exe and C5PRH115.exe),
3.4. I have used 8GB, 2GB and microSD drives to initiate the Fn+Esc procedure: formated FAT32, laptop unplugged, USB in, <Fn> + <Esc>, laptop plug, power button pressed. Fan spins up and the laptop reboots but gets stuck.
===> RESULTS: Nothing, I can’t get past the BLACK SCREEN + keyboard lights on.
I bought my laptop through Amazon but I got sent it to South America where I live (sorry for my English); service centers down here tend to do a lousy job so I am avoiding them at all costs; besides the warranty does not apply down here...
====> What I need: the appropriate name for the isflash.bin BIOS recovery file for my Acer AN515-51 <==== or any other help you could provide me.
Thank you very much in advance.
