Hi! When i was updating bios (A04) my notebook restared. And now it is not work(1 beep and black screen). I tried to flash the BIOS, by analogy with other laptops DELL. 1)Disconnect the battery. 2)Recorded on a usb stick with the firmware file (.fd), renamed differently( A14R1.hdr, M14R3.hdr....). 3) Inserted the usb stick(8Gb, 4Gb FAT32) into the usb port. (tried at all) 4) Turn the laptop with a END (with charger) Fan starts spinning fast but the flashing does not start. Help me please!
