I have just installed a new bios on my acer aspire 3694wlmi, can it be undone?

Question

recently installed bios on my laptop and now i cannot switch on the internet, any suggestions?

Answer 1

No I don't think you can undo a BIOS flash update.  

Answer 2

I don't think so, I remember when I installed Vista and it said are you sure you want to flash as it cannot be undone, I think it can be updated but not undone.

Answer 3

Yes, you can simply flash your bios to an earlier version.  You will need to go to Acer's website and find an eariler version, download and flash it.

However, I recommend debugging the issue first.  When you flash a bios, you reset all the values to a default.  The default values may not be what you want.  Hence open you bios and review the settings.  There may be a setting that turns the radio (transmitter) on/off.  If the default values is off, then would explain why you can't connect.

Answer 4

Just a thought, check the WiFi/Ethernet are still OK as it is possible that there is an update to there functionality in the new BIOS version.

Answer 5

The only way I can think installing an updated BIOS can stop the internet working is if it somehow disabled the on board network connection.

Go into the BIOS, make sure it is enabled.  If it is, go into the Windows control panel and make sure there isn't a problem or conflict with it.

It just isn't feasible (unless there's something obvious I've missed) that a new BIOS will cause the internet to stop working.

In answer to your actual question.  No, unless you happen to have made a back up of the BIOS before you updated or can download the old one, you can't roll back.
