Acer insyde bios update12/13/2022 Ok enough fluff, lets get to the solution.įirst let me clarify, this solution is applicable to resetting/clearing the corrupted/incorrectly set BIOS of a device where no other means exist to allow it to boot (no cmos clear jumper/ no removable cmos battery/ no removable device battery/ no BIOS reset button/ shorting BIOS pins doesn't clear settings/ USB ports not working with peripheral devices/ display is disabled / device doesn’t boot at all/ no sounds). I am seeking out forums where this problem lies unsolved, I am creating an account specifically to share the solution as I have struggled myself with this and have not received any help other than having to send the device back to the manufacturers to replace (and losing whatever data was on it), even the company's technicians can't give me simple instructions how to reset/clear the corrupted BIOS, their solution was for me to travel to a country where a service Centre exists to have the device replaced under warranty, the ticket alone would be more than double the amount of the device. Though I believe installing a windows 8 on a fresh HDD (you need a spare one, of course), booting that one, then restarting in safe mode (recovery mode) and going to UEFI menu should also let you change BIOS settings again. So now I can finally cancel the 4 gb download of the Windows 8 OEM DVD. Put all back together and voilà!!! It works again. I removed the battery for 2 minutes, in the meantime I plugged the power switch cable to the motherboard and pressed the button for 10 seconds. And it did indeed!!! Getting to the bios battery is a pain on this poorly built laptop: remove battery, remove a myriad of screws, unplug cables, remove motherboard and get to the battery. I thought, if I remove the motherboard battery and clear the BIOS storage it might go to default settings and enable again UEFI boot with Safeboot. While downloading an OEM DVD through a torrent client, I read this post. I removed the HDD and got a blank one, I put it in the computer and left it ready to install a fresh new version of Windows 8 (not 8.1) on it, but for that I needed the installation media (which I didn't have). So I had to figure out a way of accessing the BIOS menu. Then I realised I had disabled UEFI and Safeboot on the BIOS menu, well that's the problem, that installation of Windows 10 will not boot at all in legacy mode. I played around and tried the usual tricks (windows installation media, fixboot, and all the usual command prompt things that you try in these cases). Once I turned it off again and removed the DVD I got the fatal message error, OPERATING SYSTEM NOT FOUND. The computer rebooted and I could use the DVD, no problem. I accessed the BIOS menu as described above (not F2), then disabled safeboot and enabled legacy boot support and changed the order to be able to boot from CD, as I wanted to boot the computer with a live Linux DVD. Today I was fixing a laptop with windows 10. So if the computer doesn't boot into the HDD because of a miss-configuration of the BIOS, no luck for you. The BIOS on that laptop can only be called from Windows 8 or 10 (not 8.1), by restarting in recovery mode (aka safe mode) by holding the shift key when hitting restart on windows. Acer Aspire V5 will not display BIOS menu, no matter how many times you press F2, or whether you remove the HDD or whatever you try.
