The Bios update process is always risky. You will do this at your own risk.
Situation looks like this.
If you will upgrade the Bios you should be able to downgrade it.
I remember that once user reported on our forum that he was not able to do this, but I think that it was an exception.
How to do this?
Download the previous version and use the same procedure as for the upgrade.
Link to the all Bios updates: here, here and here.
What will happen if the Bios update process will not end with success?
Well it depends...
If you will not be able to switch on the notebook only visit in the notebook service will safe you.
If it will boot but there will be black screen problem you will have a chance to use the recover method for the Insyde BIOS which is here. It may work and it may not work. It's not easy to do for sure. If it will not work then again only visit in the notebook service will safe you.
How to update Bios?
Download the latest Bios update for your specific model here.
Plug the AC adapter to the netbook.
Disconnect from the Internet. Close all currently running programs. Disable anti-virus and firewall.
Double-click the Bios update exe file. It may take some time, so it is important to remain patient, do not interrupt the process. Allow the notebook to restart after applying the updated BIOS.
While this update is running:
- do not switch off your laptop,
- do not unplug the AC adapter,
- do not try to run any software or do anything on the notebook.
