How to update the BIOS on a PCAudioLabs Laptop
The following is an overview of the BIOS update and steps necessary. Please note; updating your BIOS is not suggested, and not needed in most conditions. Please do NOT use any third-party BIOS files for your laptop — if you do, it will void your warranty. Please ONLY use BIOS files sent to you by PCAL. In order to obtain this, please send us an email for support, or call 615-933-6775.
Please note that when updating the BIOS, data loss is possible. You could render your system unusable. As such, we do not suggest updating the BIOS yourself.
If you’ve read and agree to this, please read on for instructions.
- Make your USB drive bootable for FreeDOS environment (MS-DOS may also work). You can set it up using any utility of your choice, such as Rufus.
- Unzip/extract the BIOS& EC files from the download and copy the extracted contents to your bootable USB drive
- Restart the computer with the USB drive inserted. Once Windows has closed and the computer is rebooting, hold the F2 key – this should open your BIOSsetup menu.
- In the BIOSsetup menu, using your arrow keys, navigate to the “Boot” tab/section.
- Highlight “UEFI”, press enter, and select “Disable”, then press enter (if already disabled, skip this step).
- Press F4. At the “Save changes and exit?” prompt, highlight “yes” and press enter.
- The computer will reboot again. Hold down F7 – this should give you a smaller window that will allow you to select which device to boot from. Select your bootable USB.
- At the command prompt, type in: STEP1
- The computer should update the EC firmware, then shut down. Power the system back on and repeat step 7.
- At the command prompt, type in: STEP2
- The computer should auto-reboot. Use F7 to select your USB drive again.
- At the command prompt, type in: STEP3
- The computer should have its BIOSupdated, which will take about one to two minutes, then it will shut down a final time.
- Power the computer back on. You may receive a message notifying you that the firmware was reset. Press enter two to three times to dismiss the messages, then the computer should auto reboot.
- Use F2 to re-enter your BIOSsetup if you need to re-enable UEFI to get back into your Windows install. If you did not have UEFI disabled, you should be able to skip this step.
