Blinking red-blue LED on side?

I was about to resurrect a thread with a similar title, but my symptoms are a little different. I changed the title only slightly because the other thread was the closest I could find to my problem and I figured for someone else with this problem would more easily find this.

FW 13 Intel Core US1, Ubuntu 24.04, BIOS/firmware 03.04. Everything is working fine. However, when the charge reaches 80%, the charge limit I set, the side LED almost always blinks red-blue. If it’s not fully charged, it is a steady red. Normally, when it reaches 80%, it is a steady blue. It only blinks on the side where the charger is plugged in.

I checked the keyboard cover micro-switch. It clicks when I press it and the pad seems to line up correctly. The screws on the bottom are properly tightened

As a test, I loosened the screws and while on the charger, I lifted the keyboard. The LED went from blinking red-blue to blinking just red. I put the keyboard back down and it went back to blinking red-blue.

I’d like to leave it on the charger once it’s full because, as I understand, when it’s charged, charging stops and the computer is powered directly from the mains – best for the battery. Without knowing what the blinking means, I’m reluctant to leave it plugged in.

Any ideas? Thanks!

You should file a ticket with support. Not all the blinking states are well known.

I believe the change from Red/Blue to just Red flashing is indicative of the switch recognizing the cover is off while it is running. (Like a chassis intrusion indicator)

I know when the charger reaches the charging limit I have set on a Framework 13 (11th gen board) and the Framework 16 it turns white. Maybe it is different with the Ultra chip version?

Could be something with the BIOS (in one of the modules like the charge controller or EC) or something on the hardware level that is causing the blue/red flashing state. I would guess that is an indicator code of something; what though support should be able to help detail for you.

Let us know how it turns out.

Yeah, that’s why I did the test, to make sure the red-blue wasn’t somehow related to the intrusion switch.

Blue, white. Might be the same. It’s a very light blue, like sky blue with whispy clouds and seagulls flying. More or less.

I’ll ask support. I wanted to see if anyone else has had this issue.
