HDMI Module Power Drain Issue

Hi there, I received my framework laptop today and so far everything seems to work just fine.

I am however curious about whether or not the Battery Drain issue caused by the HDMI module has been solved already, or if there is some sort of workaround, assuming it hasn’t been solved yet.

I asked this same question on reddit and got told that this issue continues to persist due to the fact that the issue lies with the hdmi module rather than the laptop itself. They haven’t gone into much further detail unfortunately, so I thought I’d ask here.

Thank you in advance.

Hi and welcome

This has been discussed in other topics, try a search.

If I find one I will update here and ask that your query be move to it.

What issue do you have?
When powered off there should be no drain
In sleep mode there will be

Maybe read the examples below and contribute in one of them

Not solved yet, but if you read through this other thread, Framework is working on a firmware update for the card to solve this issue.

thank you for the info.

I thought the power drain also happened when powered off completely. But if it doesn’t then It’s completely fine for me.

Thank you again for replying to my post.

For some more clarification on this, the issue is DP Alt Mode devices (HDMI Expansion Card and DisplayPort Expansion Card for example) keeping the Intel retimers from entering into a low power state. In theory they should, but in practice, there seems to be some bugginess in their behavior. This impacts active and standby power, but not shutdown/hibernate power usage. We have firmware work in progress which works around this issue and forces the retimers to suspend correct. In addition, we have a beta DisplayPort Expansion Card firmware that changes the card behavior to work around the retimer issue. We’re also working on HDMI Expansion Card firmware that does the same.
