Fix recurring Asus motherboard "F2 to restore BIOS" message

TechRepublic member solves a recurring Asus motherboard "F2 to reset BIOS" message by replacing BIOS battery.

TechRepublic member zackery69 recently asked TechRepublic's community of IT professionals for help with an annoying Asus motherboard problem. Each time he powered up his machine, a message appeared asking him to press F2 to restore the motherboard's BIOS. The machine would run fine once he complied with the message, but the routine was getting old.

According to zackery69:

"its been like this ever since ive bought the motherboard bout a 6 months ago... ive recently upgraded the bios form the asus website and it has the latest bios on it but i still get the error message ,does anyone know how i can get rid of this annoying message ...? wen the pc boots up it runs fine its just turning it on youve always got to press f2 to get it booting up..."

TechRepublic members were quick to offer solutions. OH Smeg suggested the following potential fixes:

  • Entering the Date & Time
  • Configuring the BIOS to run on Default settings
  • Setting the BIOS Clear Jumper to RUN and resetting the BIOS
  • Replacing the BIOS battery
  • Returning the motherboard for a replacement

Member Peconet Tietokoneet also suggested replacing the BIOS battery. "You will be fine, also as stated above, your motherboard battery seems to be dead or dying, so replace it and then follow OH Smeg's advice," he wrote.

A new battery fixed the problem. "ok i got a battery and so far all good," zackery69 wrote.

I have a similiar problem, to bypass this i switch the power button at the power supply off after i have shutdown. if i then restart pc i need to flip the swith into on position, then bootup up and there is no more error message. it seems like a minor fix, but if it works it works.

I have an Azus motherboard. It is a P5QL-PRO. Whenever I change something major,like a new processor, hard drive, etc, and I update the information in the BIOS, when I hit the save and exit button, the machine shuts down abruptly and will not run for about 20 minutes. Then it will start and run. It does this every time I do a major change

I have the Bios says to reconfigure BIOS after the pwr supply was turned off. I checked the battery voltage and its at 3.3 v so I just bent up the contacts in holder and seems to work for another 3 months , now I get that the Bios is not set up , but the setting are all there???? reboot and ok. I will break down and replace the battery.

I only got started in this industry back in the vacuum tube days and I have to admit that I've fallen into the old trap of assuming a new part is a good part more than once - especially after working many hours into on a repair. Remember there's three syllables in the word assume, ass u me. When you assume you make an ass out of you and me!

Those batteries commonly have a shelf-life of two to five years. Those batteries have been maufactured for many years now. Who knows how long that battery sat on the shelf before it was put in the motherboard.

REALLY? A reset bios message and it took that many people that many days/weeks to figure out to replace the battery? Granted it's not a common problem, and granted I've only been in the IT industry for the last 15 years, but it is an old-school problem with an old-school solution. After one message, sure, just a hiccup. After the second message and updating the bios didn't work, I don't see how there is any other option BUT to change the battery.... Who cares how old it is? If you get a new cell phone, out of the box, from the manufacturer, and the battery dies after 15 or 20 minutes on a full charge do you honestly suspect that it might be the date and time of the phone that's causing the obviously dead battery? Or has the quality of the workers in the IT/Support industry gotten so pathetic that no one even knows what a BIOS battery is? Really....? Reminds me of any of the hundreds of versions of 'how many _____ does it take to change a lightbulb?...'

Being a 4 month old mobo you wouldn't suspect the battery. I hope it was just a bad/weak battery, otherwise you may have something draining it too quickly.

Yeah, it's like nobody has heard of a new defective part. I've been in this industry doing hardware repair since the first IBM and Apple PCs. Don't assume anything! If a system is losing the bios it's almost always battery related and changing the battery is kind of easy and inexpensive. Even if you just rob one off of another mboard. If the problem either doesn't go away or returns shortly then it's time to look elsewhere. Yes, over the years I've also overlooked the easy repair many times by second guessing myself and wasting time and money on what should have been something simple. We all do it at some point. You just go "DUH" and move on.

I've worked on more computers than I care to remember and maybe I'm just just lucky, but this is not common for a new motherboard. After several years of operation, yes, but not fresh out of the box. Must have been a bad batch of batteries, or let's see if the problem recurs. Maybe zackery69 can post back if it does.
