Trying to track this down. 3 boards all same problem. Rampage IV Extreme, Z87 Pro, Z97 pro. All boot and function correctly but all lose bios and time settings if power is shut off. If power is maintained, sytrms boot and reboot normally. I have verified cmos battery is supplying 3v to board. 8 pin bios chip has continuity to ground but no voltage to vcc pin. I assume that's the pin that maintains the settings with power to bios chip. How do I track this down? What voltage do these bios chips require?

You should be able to read the BIOS Chip thats on the motherboard and look into datasheet. There should be listed what voltage the chip needs. -
I guess im not really lookig at this correctly. Apparently the bios chip gets 3v when it's powered on and indeed it is. I always assumed that it should have voltage when board is unplugged. I ordered a bios chip for one of these boards to see if that isn't the issueComment

Hi all, I've spent the past week digging through the forums and guides to try correct my foolish mistake of changing hidden settings while tinkering around, and to be honest my heads overloaded so I'm hoping you'll be able to help.
I used a tool called 'Smokeless-UMAF' to access usually hidden settings in the bios. I tweaked one or two 'safe' things but made the mistake of tweaking a lot of settings under 'USB/Thunderbolt Configurations' when I didn't know what they did. For... -
Hello. I am asking you for a hint on how to solve the problem with my touchbook Panasonic CF53-2 standart model. After setting up the BIOS, the laptop displays the wrong image until Windows loads. (More precisely, it displays, but distorted, instead of the Panasonic image immediately after turning it on, it displays what is in photo #1 in the attached file) Then the image appears when Windows starts loading and then there are no problems with the screen until the reboot. If you enter the BIOS, just a black screen. If you connect an external screen, the image on it is the same as on the built-in... -
Hello everyone,
I’m currently working on a dead MSI GP75 Leopard (MS-17E71) motherboard (i7 CPU, NVIDIA GPU) with a no display/no backlight issue initially. After extensive investigation, I’m at a critical stage involving EC firmware, BIOS/ME region interaction, and possible deep corruption. I'm seeking advanced insight from anyone with experience in EC/BIOS sync issues or PCH-level behavior. Here’s a full breakdown:
🧩 Initial Issue- Board powers on (fans spin, keyboard lights up and can be adjusted, caps lock led lights), but no display or backlight
- External display (HDMI) shows

Hello... Where do I start. I have 2 questions/scenarios that might bring this laptop back to life, so here it goes!
I have this laptop (Asus UX52VS) where I was flashing the BIOS to it and it froze during the process. I didn't have a reliable BIOS chip programmer at the time (It was a CH341A USB Programmer from Amazon where it took hours just to get the clamp on the chip and then every time I read, it gave me different results/corruption, and never would pass the verify test as no 2 reads were the same data), so I brought it to a shop. They had it for almost 2 months, but during... -
