Disable chassis intrusion blinking

No worries. I emailed support. This issue affects both 12th and 11th gen. Also the 12th gen doesn’t power on with “ac attach”.

The BIOS setting to disable the blinking LEDs for chassis open is called “Standalone mode”


Which bios version does that show up in? Where is it?

11th gen, BIOS 3.17, under the Advanced section, option is called “Standalone Operation”

The option description says:
Skip hardware checks for chassis open, display, battery and C cover when operating in standalone mode.


Where can I find this bios? I have searched and can’t find it.

Oh, It is in beta. BIOS guide
No thanks. I tried a beta bios update on a 12th gen and bricked the board.

@Andy_Clemenko Bricked the board? As in rendered it completely non-functional with no recovery? Because that would be new to me.

Yup, a 12th gen. After the first update on one side it would not boot/post.

I even had 2 boards die on the left hand usb ports.

Just tape over the LEDs or the intrusion sensor then I guess, or just don’t look.

…and technically, it’s in an enclosure…one that lacks the design to press onto the intrusion sensor. So, maybe improve the design of the enclosure.

@Andy_Clemenko Have you reached out to support about this? Or messaged @Kieran_Levin? Beta software can have issues, yes, but shouldn’t be capable of bricking boards entirely. I’m sure they will at the very least be interested in learning what went wrong.

I have reached out several times. I got the 1280p replaced. And I opened a ticket about the LED.

Turns out I thought I was on the latest bios. Nope. sorry… But now I can’t update the bios without a battery?

@Andy_Clemenko That does seem like an oversight. @nrp @TheTwistgibber?

I found the work around. NOT IDEAL.

@Andy_Clemenko details please in case someone else stumbles on this thread looking for answers? But yes, this doesn’t seem to be a terribly good UX.

Not an oversight as we mentioned that the BIOS had to be updated in order to utilize a “no battery” setup.


@TheTwistgibber Ah thank you, so if there was a battery present, he could update and then future updates would not require a battery?



The work around is to extract the platform.ini from the exe, modify it and then add it to the boot device.

I believe we also have an updater improvement in development that allows for an update process without a battery. Part of the challenge in this is being able to update the PD controller firmware, which can’t be done if the PD controller is actively handling keeping the board powered. Instead, we have to update in sequence, switching the plug to the opposite side of the board partway though.
