System restores from saved bios settings after power loss.
System restores from saved bios settings after power loss.
Hey guys, I have been having a problem where my BIOS settings, date, and time resets whenever the power to the computer is shut off. I already checked the 3V motherboard battery and it is good and seems to be making good contact, so so I am not sure where to go from here. There is no system battery voltage data in the BIOS, so I am not sure how I would verify that the board is actually receiving power from the battery. Thanks in advance for your help!
I meant to share my specifications. This was about a year ago. Appreciate your assistance with the CPU Intel Core i7 6850K, motherboard Asus X99 Deluxe, RAM 2 X 8GB G Skill Tritent Z RGB 3200 MHz, GPU EVGA GTX 970 FTW with EK FC waterblock, case featuring Fractal Design, storage Samsung 960 Pro NVME 512GB, PSU Seasonic Prime Titanium 1000, display options including Samsung 4K TV with cooling, custom loop keyboard, Logitech G710+ mouse, built-in sound, TV speakers, and running Windows 7 Ultimate 64 Bit.
Nice rig my friend.... For 1 year your dealing with this that is crazy. I think you should buy a new battery, or something fishy is going on with the motherboard. However it does save your OC settings or whatever changes you have made ? .... Best thing I can suggest after the above is to just put your computer to sleep instead of shutdown. Also you can look into flashing the BIOS of your motherboard and that might trigger things and the time and stuff will stay.
Thank you for your help. To be clear, I can leave the computer shut down for as long as I want no problem as long as the PSU is plugged in and the switch is turned on. But if the switch on the PSU is turned off or the computer loses power, all my BIOS settings are reset to default and I have to reset the date and time. Long story, but this is my second X99 Deluxe motherboard because my first one died and Asus sent me a refurbished one, which has other problems like dead fan headers, dead ports, and missing serial number. I thought about updating the BIOS, but I am somewhat afraid to since I am not sure what would happen if the BIOS is flashed with no power from the battery. I presume nothing bad would happen since to the best of my knowledge the battery isn't used for anything while the system is plugged in, but I am not sure. If you have input on this I'd appreciate it though
ASUS consistently delivers me fresh components. It's frustrating when it's only affected by power management—like turning off the power button or unplugging it. I assumed it happened during a basic shutdown then restart. Actually, it seems modern systems handle power switches without drawing much power. When the power is on but the PC isn't, it doesn’t consume significant watts and the motherboard indicator stays lit. USB devices can charge, using a few watts based on the load and number of devices.
Thank you for your feedback. I understand it’s not a major issue, but I’d still prefer to resolve it without swapping the motherboard. It frustrates me that I’m forced to restart all my BIOS configurations, dates, and times whenever I power down the system for cleaning, upkeep, repairs, or outages.
Ya it's a bitch I know... But one tip I have is, Save your overclock settings; your motherboard gives that option. So next time you just go and choose that overclock you saved and load it. Unless it gets rid of that as well.. hmmmm sighs. I would be happy your system is stable because it is a refurbished board and this is the problem it came with ya know.
Good thought to store my preferences in a profile, I haven't explored that yet. I'm sure the device would erase them as well. I'll likely jot down my custom settings or save them on my phone so I don't have to recall everything. It's frustrating, but it might be worse than the alternative.
I discovered fixes for AM4 motherboards regarding losing BIOS settings after powering off. These steps only apply to your situation. You need to replace the CMOS battery and flash the BIOS, but still you might require some soldering skills or someone with expertise. The reset pin jumper draws 1.5V, and locate a resistor close to it—this one is 1kΩ. Change it to either 200Ω or 300Ω, but avoid applying voltage directly to that line since it connects straight to the processor’s RTC. If you see a short circuit, locate a capacitor and regulator near that resistor and repair it. Always remove the processor before working on it. For 2-pin resets, check the one with 1.5V and find that resistor. For 3-pin resets, measure the middle pin. You can find tutorials on Xinzhizhao software; an AB350 schematic is a good reference. AM4 socket motherboards have similar CMOS battery wiring. Proceed at your own risk if you’re unsure—don’t proceed without proper knowledge.
