Hello everyone, I encounter difficulty to find a functional bios after a flash downgrade bios (because is a EBAY used motherboard it was impossible to run the GTX 1050 an error 43) so I flash via Windows a bios former which I have to modify the flag. the procedure is well done, I have the progression run in back. the PC redémre and it is the black screen ... and the backlight of the keyboard remains lit. by doing the combination fn + Esc I get flashing USB keys but I try tt the possible name of bios (* .fd) to rename the file extracted from the latest version of the bios. Remove & reset battery (power on one night...) = no result If anyone can help me, I will be very happy. ACER SPIN 5 515 51GN
Identical result. Protocol: Fat 32 usb key with just the .fd file on it. I press fn + esc then power. the led of the key flashes 1 second then the PC goes off and restart (except procedure recovery) black screen and keyboard light Sorry for my english (french)
Your English is fine...no worries. Please check these things: - Try all the USB ports on your laptop. Sometimes only one of the USB headers is usable for recovery procedure. - Not 100% sure on this, but ensure the USB stick is 4GB or possibly smaller. I usually restore laptops with a 2GB, 1GB or even 512MB SanDisk USB stick formatted as FAT32.
thank you for your help @tqhoang I just tried with a sandisk key (16go I have no less ... I even tried to make 1 go partition on the key) on all usb ports, same result ... when flashing bios under windows with insyde there must be a copy backup to the hard drive?
