*NOTE: Not all devices will produce beeping sounds during the recovery process. If the recovery process was successful, then the BIOS should work normally the next time you boot up the computer. About 5 seconds after the flashing process has finished, the computer will shutdown.
The computer used in this tutorial took about 32 seconds. During this process, the computer will beep every 2 seconds. No beeps will be heard during this process.ġ2.) After the computer is finished loading the BIOS file, it will start flashing the BIOS. The particular computer used in this tutorial took 12 seconds to load the BIOS file, but times can vary based on the size of the BIOS image. If the BIOS file is not found, the computer will reboot and try again.ġ1.) If the file is found, the computer will load it. The number of beeps can vary based on the capacity of the flashdrive as well as the number of files on it. While searching for the file system, the computer may (should) beep for one second. You may notice some of the LED’s illuminating differently from how they do in normal computer operation.ġ0.) After about 10 seconds, the computer should start reading the flashdrive. Do not release these keys until instructed to do so.ħ.) Connect the AC power adapter to the computer.Ĩ.) Press the ‘Power’ button on the computer.ĩ.) When the LED’s illuminate, you may release the two keys from step #6. That being said, some computers are finicky and will only accept a specific USB port for recovery.Ħ.) With all power sources disconnected from the computer, hold down the ‘Windows’ key and the ‘B’ key.
In most cases, the particular USB port that you use will not matter. If the flashdrive is not empty or is incorrectly formatted, the recovery process may fail.Ĥ.) Disconnect the AC power adapter and, in the case of a laptop, remove the battery as well.ĥ.) Insert the USB flashdrive into one of the USB ports on the computer. The file extension will usually be one of the following: “.fd” “.rom” “.bin” “.wph”Ģ.) Please see paragraph 3 to determine what you should rename the BIOS file to.ģ.) Copy the renamed BIOS file to an EMPTY USB flashdrive.
