Re:Lenovo X1 Carbon Gen 9 Throttling Issues

@mcjazzman I wish I had a better grasp of what the underlying issues are - and how updates can address them.  Perhaps the update README will tell us more.  If I can dig up additional detail I'll post it.

In my opinion the best we can expect is a new BIOS setting to limit the charging power, manually or automatically in the thermal regulation loop.

 

And, let’s have a dream, a clear statement about any hardware/heatsink issue.

Yeah, ideally they could cut the corporate bullpoop and tell the truth:

- Should we get an i5 config instead of i7?

- Should we get a 45W charger instead of 65W?

 

I would much rather have the truth and make an informed choice than having to guess based on obscure updates Readme files...

Day 6/14 and we have no new BIOS. 🙄

 

What surprises and worries me the most is why lenovo does not detect these bugs (we have two and very serious) in the design and testing phase of the product.

 

So many engineers and so many quality tests to end up releasing a BIOS update every week?

Yeah, I noticed :(  I'll dig around a bit and see if I can find out what's up.  No promises, except that I'll try...

All,

 

Seems there was a miscommunication re internal vs. external access to the update.  Best I can come up with is an expected 6/24-28 date for general availability.  I can't swear to that.

 

My sincere apologies for raising expectations prematurely.

It's hard to imagine at this point that they can fix it with a firmware update. It seems there is a thermal design issue and it's always going to be a trade-off between over-throttling and over-heating (or over-fanning).

But ok, let's give them one last chance before I order another laptop. July is the deadline for me.

I would expect them to keep fine-tuning that, but without better venting/heatsink/fan options (hardware changes), that's about all we can expect. The worst case scenarios of heavy CPU usage/need and combined fast-charging would still be a problem, the design is the issue, a tradeoff for being thin and light.

What I did to lower the effect ot this the crappy assembling on my (20XW / i7-1185G7) is to set Power Balanced on AC at BIOS, lower the multiplier with ThrottelStop to 30. Now even with AC and ext. monitor on USB-C temperatures is not going over 77C.
