This quick tutorial and guide show you how to flash your firmware (update BIOS) of any modern ASUS board.
Just note that some of the modern board manufacturers (MSI and ASRock both included) will also allow BIOS flashing over Ethernet or a wireless connection, though USB is still the most convenient, easy, and safest method.
How to update the BIOS ASUS laptop?
- A board with a simplified firmware flashing software.
- The most recent version of your board’s BIO, which is found on the manufacturer’s site.
- Store this on the USB device.
Cautions and Notes
Sudden power loss or power disruption by the user can brick or damage the board which means that it will be as useful as a brick when it comes to computing, meaning it will be of no use. Do not disconnect the power at any time during this whole process. Do not perform during electrical storms.
When you are updating via the internet, most of the boards will store the update locally, wipe out the old firmware, and then apply the update.
If your board does not do this, but in spite, it requires a constant internet connection, then it is advised not to disconnect your wire during the update. I would also advise you to choose a wired connection over a wireless connection.
You also have to note that flashing BIOS will wipe all the settings, so it is recommended that you write down any overclocking settings before you proceed further.
Note that most of the high-end-boards – such as MSI’s Z97 GD65 – provide a “dual BIOS” feature. This is a beneficial thing.
The reason that flashing firmware can brick a board is that there is no existence of consumers which means recovering the corrupted firmware chip.
To update firmware, the board must, first of all, wipe the existing blocks housing the firmware, then apply the update block by block to the flash device.
Failure or power loss during the wipe phase will mostly result in disastrous failure – or it may result in an uncoverable corruption to the Flash memory.
Dual BIOS eliminates this concern. If BIOS fails due to a bad flash, a physical switch on the board can be toggled to enable the backup BIO chip.
For most of the users, it is recommended that you do not fix something which is not broken, to paraphrase an adage. Updating BIOS is advised in an example of new features (such as support for new CPUs and unlocking CPUs) or fixed features (often, this is RAID).
Steps to follow to update BIOS on an ASUS Motherboard
- Do it boot before installing anything then follow to BIOS.
- Navigate to “Tool” then “EZ Flash.”
- Check your current BIOS version and make a note.
- Download the most recent BIO iteration from the ASUS website. Store this on a USB device.
- Boot to BIOS. Navigate to “Tool,” then “EZ Flash.”
- Select the USB device, then select the file and press enter.
- You will be prompted one final time before you apply the update. Review his and accept it.
- Reboot when it’s completed.
- Check the BIOS version again to make sure the update was applied successfully.
- You will need to re-apply BIOS settings manually.
That’s all! You are all done. You have updated the BIOS of an ASUS motherboard.
How to upgrade BIOS on ASUS without having a Battery?
When you are having a laptop with no battery and when you start Easy Flash to upgrade the BIOS and it tells you that you need a battery which is charged at least 20 percent, then just type on your keyboard the word “risky”, and then it will bypass the battery check, which will allow you to flash the new firmware file.
Warning: if the firmware is in the middle of applying the update and the device turns off, then you could brick the machine of which you are flashing the firmware.
You can update the BIOS without a battery by following these steps:
- Download the new BIOS and then copy it on a USB key (FAT32).
- Start and enter BIOS, then in the BIOS menu go to Advanced and then select “Start Easy Flash”.
- When the system will display that you cannot update the BIOS because there is no battery, then just write the word “risky” from your keyboard.
