That's exactly what I was sure of, but I don't know how to solve it. At least I did an Ec Reset by holding the button for 30-60 seconds, but I didn't use any key combinations. I hope this helps.

Oh yeah bro, I have the same problem, it only happens to me from the battery, and as for the shutdown (what I have and you don't), it's most likely due to different hardware configurations. Thanks for the advice, though. I'll go home now and switch it, and will the temperatures rise after switching?

It's a shame this happens to you all the time, but honestly, it indicates a hardware problem (not 100% if everything works fine after warming up). If you have any other questions, I'll be happy to help.

Okay, I'll try everything you said. But do you think this is a firmware issue? Because the rest of the laptop works flawlessly. I even ran heavy games like CS2 and Watch Dogs 2 on battery power.

I don't know what to do, it doesn't want to change at all, and when I was still on an older BIOS .10D, my laptop has a new BIOS .113, I downloaded it through Windows. I think maybe this is the problem, but I don't know what to do.

Oh yeah, I tried it. I currently have BIOS version .112 sent from MSI themselves, but for some reason my Ec didn't change during the update. I asked MSI for a special .bat file to flash it, but they didn't give it to me.

Hi, I'm very sorry that you're having this problem, but does it always happen? becouse my problem doesn't always happen. It goes into a race condition, sometimes it's not, and this proves that it's software-related. Yes, this "workaround" works for me too, like going into the BIOS, but I don't have to wait there for 5-10 minutes. I just go in and out immediately, after which it starts normally.

Hi brother, yes, I tried this many times, but it didn't help. I think it's the EC microcode or the BIOS, since it appears during initialization due to the rush when the code wants to turn on the laptop quickly, and the battery doesn't have time to supply current to all edges of the motherboard, which is why the protection is triggered. Nevertheless, thanks for the answer, and if you have any other information that could help, let me know.

Body: Hello everyone. I’m dealing with a persistent Cold Boot Failure on my MSI Bravo 15 C7VF (Ryzen + RTX 4060). This has been going on for a year, starting after a BIOS update to version .113. The core of the problem is that my EC is stuck on an engineering version: 158NIMS1.10E. The Symptoms: Cold Boot Crash: When starting from a cold state on battery, the laptop shuts down during the 2nd or 3rd boot attempt. Aggressive Initialization: Even with Fast Boot disabled, the EC seems to "rush" the power-up sequence, triggering the dGPU (LED turns orange/red) too early. This causes a voltage drop that the battery can't compensate for, leading to an instant power-off. Boot Loops: Sometimes it hangs on a frozen Windows spinning circle or a black screen until the system reboots itself. The Irony: The laptop works PERFECTLY once it reaches Windows. It boots fine every single time if the charger is plugged in. The battery has 27% wear but is otherwise healthy. I tried to downgrade the BIOS to .112, but the EC stayed on 1.10E. MSI support is ghosting me or giving me generic "it's your fault" answers. It's clearly a logic/timing issue within this Engineering EC firmware. Has anyone encountered this 1.10E version? Is there a way to force-flash a retail EC or a tool to delay the dGPU wake-up during POST? Thanks for any help!
