Today I decided to update the BIOS to the latest version (0325) to try to correct a problem with a bluetooth keyboard not being able to wake the laptop from sleep.
I performed the BIOS update through the "ASUS update utility" http://support.asus.com/technicaldocuments/technicaldocuments_content.aspx?no=714 using the "update BIOS from the internet" method. I may have made a mistake, as I had not read the "Rules for Safe BIOS update" on the ASUS page. I did not do the following:
3. Load "Setup Default" in BIOS menu before BIOS Update.
6. Disable any existing Anti-Virus applications in the system.
8. Switch on the PC and load "Setup Default" in BIOS again.
When I restarted the computer I noticed that it was behaving strangely. I had it plugged into a plasma TV and the display kept disappearing. Also, I noticed that the power status in the task bar showed it did not think a battery was inserted in the laptop even though it was.
I tried restarting and got the following message:
PLEASE ENTER SETUP TO RECOVER BIOS SETTING
PRESS F1 TO RUN SETUP
PRESS F2 TO LOAD DEFAULT VALUES AND CONTINUE
When I press F2 the computer just goes to a black screen with a blinking cursor at the top left.
If I press F1 I can't see any settings that would solve the problem (as far as I know)
I tried using EZ Flash to go back to the previous BIOS version (maybe this is impossible?) and then I tried using EZ Flash to reload the most recent BIOS version again and the pc reported it was successful.
Now when I turn on the notebook it gets up to "checking NVRAM" and then just goes to the blinking cursor.
Is there something wrong with the motherboard, or has the BIOS update caused some problem, or is it something else?
Is there anything I can do to fix this myself, or will it need to be repaired by a service center?
