G50V-A2(A1): Solution to the double-POST / no second HDD found after BIOS update issue

Hey everyone,

First, I cannot take credit for this solution as I discovered it on the official ASUS forums posted by someone named Fowler so I'm giving total credit to him. I just wanted to repost what he said over there (sorry...I can't provide the link as I don't have 15+ posts yet apparently but go to the offical forums and try searching for Fowler or look for his post titled "BIOS Cycle's Twice" under the G50V section) in my own words based on my own experience.

[Problem] After updating the BIOS, I found that my system would constantly restart after it went through POST, the second time not being able to find the second HDD. GenTechPC described the problem as basically a glitch with the BIOS where it "thought" the user had pressed F9 to start the System Recovery option from the hidden partition to load the OS back to factory defaults (which if you actually pressed F9 during post would occur so this made sense). However, nothing aside from completely restoring the OS to factory default seemed to fix the problem of getting the BIOS to actually see the second HDD and boot as normal. That is until I tried Fowler's solution.

[Solution] As stated by Folwer from the address I mentioned above, what I had to do was this:

1. Load the new BIOS (in my case I upgraded from version 203 to 205) as normal [see instruction on how to do this elsewhere] and then reboot the laptop.

2. When the exploding RoG logo appears, press ESC to switch to displaying the POST info. and then press F2 to go into the BIOS setup.

3. Go to the last BIOS page and select LOAD MANUFACTURER DEFAULTS. Then select SAVE AND EXIT which will reboot your laptop again.

4. Exploding RoG logo appears, press ESC again and then press F2 to go into the BIOS a SECOND TIME.

5. Again, go to the last page but this time select the LOAD USER DEFAULTS option. This is the MOST IMPORTANT PART to this solution. Select SAVE AND EXIT which will reboot your laptop again.

Your laptop should now work perfectly normal without it auto restarting on you like it was doing before if you tried updating the BIOS but only went so far as part 3 (which is what I had been doing before). In addition I went back into the BIOS again only this time I made my own personal tweaks based on personal preference: disabled the touchpad, disabled the exploding RoG screen so that it shows POST info. and turned volume down to zero so that I didn't hear the explosion every time my laptop boots.

I hope this solution works for you if you've encountered similar problems. I cannot accept any responsibility for any actions / problems encountered if you attempt this solution as I only wanted to post my own personal experience for others to hopefully learn and benefit from. Updating the BIOS should only be performed if you are tech savy (i.e. know what the hell you are doing) and willing to accept the consequences should you screw something up so it's NOT RECOMMENDED. Just wanted to make this clear. UPDATING YOUR BIOS IS NOT RECOMMENDED. A safer alternative to trying it on your own is probably to just RMA your laptop and have ASUS tech support perform the BIOS update for you. And if your laptop seems to work fine with whatever BIOS it came with...stick with it.

One final thing. It may be possible to skip parts 3 and 4 and just do parts 1, 2 and 5 but I wanted to show the order that I did things and was successful.

Cheers!

P.S. If you can post on the official forums and this solution works for you then you should let Fowler know as it was his efforts that solved the problem.

 

This fault also affects the G71V bios (v207) as well.

Really annoying until I independantly found the above way to get it to work. I also used to get "TPM Modual Not Found" during POST when there was this problem.

You cannot skip loading the 2 different defaults (you must do 1-5 without any skips) as just re-loading the manufacturers defaults does not seem to reset the problem settings. If you reload the settings a 3rd time it all breaks again and you have to repeat (so no fiddling until Asus fix the problems).

 

Weird. I would have imagined that Load User Defaults should work regardless of whether the Manufacturer Defaults were loaded before, or not (since the settings are rewritten/reset anyway).

Somebody else posted this fix on another thread today, I don't remember which right now. But thanks for the detailed guide!

 

Found this googling "bios double post". Thanks a million for the info, I was preparing to toss my G50 out the window.

 

Thank you!!!!! I had exactly the same problem on my brand new G71V Awesome machine. This solved my problem!!!!!!!!!!

 

I wish I would have seen this awhile ago. I just sent mine back to ASUS for service due to this problem. They've had it for over three weeks and I have no clue on when I might get it back.

 

Just call them and tell them to send it back, you know how to fix it... or guide them through the process. They will probably change the motherboard and what not...
