ASUS P8Z77 V-Pro Bios settings get lost

Featured Replies

Hi there!

Since today, I got a new problem:

All Bios settigs (date, time, o/c settings, etc.) get lost when I turn off the socket board in which the pc, the speakers, the monitor and the printer are plugged into. I normally do this every night, but today, I recognised that the date and time weren´t correct after Windows had been booted up.

The PC is 13 months old now, and AIDA64 shows a voltage of 3.24V for the CMOS battery. Could it be somehting different than this battery?

Once booted withe the correct settings, all works flawlessly and normally.

Thansk in advance for your help!

 

Any ideas or thoughts on this?

Mike, it does sound like the CMOS battery. Even though Aida64 is showing voltage, the battery might just be able to hold a voltage while under charge when the computer is running, but not overnight when it is off.

 

I would try resetting the bios with the motherboard button first. I have a similar board and corrupted my bios during overclocking where it wouldn't remember settings. This fixed that issue.

 

If that doesn't work, replace the CMOS battery. I wouldn't expect it to cost much.

 

If that doesn't work, you might have a short somewhere draining the battery. At this point I think you need to call Asus.

Thanks a lot for your answer! It might be worth mentioning that the settings get all lost as soon as I disconnect the power cord or switch off the power supply. Even if this state lasts only seconds, all is gone after the power is established again.

Where do I find the reset button? Is it on the board itself?

Interestingly i am having a similar problem with the clock i found this thread (albeit on Windows 8)

Although they refer to BIOS clock issues they also appear to relate to what you are experiencing.

My motherboard has one on the board. Not all motherboards have a bios reset button on them. You will have to look in your manual for instructions on how to reset the bios. Make sure you discharge any static electricity from yourself and disconnect the power cord before touching the internals of your computer. I usually disconnet all the cords to my computer before opening it up. Troubleshooting things like this is a process of elimination. You might also want to try disconnecting all your peripherals except for the montior, keyboard, and mouse. Start with the easy, inexpensive checks first. It could be as easy as your battery does not have a good connection in its socket.

CMOS batteries are dirt cheap and easy to replace. Why not change it, that way one variable will be eliminated.

Sure, but why should it be empty already? After 13 months? And the voltage shown in Aida is ok too. But I should give that a try since it is easy to do. The thing is, that right now everything is running nicely and I don't want to take any risk by switching jumpers, or flashing the BIOS etc.

It is not the CMOS battery and the only solution is to hit the CMOS reset button.  I had the same problem with my ASUS Z87 Deluxe.  Took me a couple of months to figure it out.  The problem is really beginning to surface on the Internet as more and more people run into this issue.  They say it might happen again to my MB but I know now how to fix it.

Ok, Jim! I'll have to see if my board has such a button or if it's done with jumpers. Shouldn't be a big deal either way...

I gave it a try, I had to move a jumper for 10 seconds to reset the CMOS, the reset worked but the problem still persists. As soon as the board is without current, all settings are gone.

I'm sure you all have, but just in case... have you checked for an updated BIOS?

 

New boards frequently have these issues.

I haven't done any BIOS update yet. Normally, I don't change drivers and such as long as they are working flawlessly...

Well clearly it's not working flawlessly. So do check the motherboard manufacturers web site, you may find the latest BIOS has a fix for it.

 

Especially with new model boards, you can expect glitches, that's why bios updates are released.

I'll take a look, but I don't think that this problem is related to an outdated BIOS version. The board isn't exactly new, also. This model is older than a year and it worked without any problems 13 months for me.
