Re: X210s

Did a bunch of testing using memtestx86+. After a bunch of passes, 0 errors on both modules. I've now managed to upgrade to the latest possible in debian (debian 9.7 with kernel 4.19). With both modules installed, I rarely can even get into a logged in state without the system crashing. If I run on...

X210 CPU cooling improvement options?

The cooling setup of X201 is inadequate to unleash the full potential of the modern i5/i7 CPUs. I wonder what are my options to improve it. The current power dissipation can be displayed by tools like `throttled --monitor`. For instance, my X210 with i7-8550U CPU at 92°C with a stock X201 cooler and...

Re: FS: [OFFICIAL CONTACT] 51nb's 4th Batch X210 [*PIC*]

It must be easy to quantify, since Intel CPUs report their power dissipation to the software. It can be displayed by tools like `throttled --monitor`. For instance, my X210 with i7-8550U CPU at 92°C with a stock X201 cooler at 25°C ambient temperature during `sysbench cpu run --threads=9` load dissi...

OK. I'll test your config with vanilla kernel. (No plans to install gentoo now).
The patch should not do anything affecting the behaviour anyway, the kernel is otherwise vanilla, and also the kernel used to work well for X201 and X230.

Re: X210 and Linux: snd_hda_codec_generic hdaudioC0D2: Unable to sync register 0x2f0d00. -11

Suspend/resume works very well to me. The only issue, I have, is related to the EC: the mouse pointer makes some jumps and random clicks on resume. And external mouse is buggy unless I touch the trackpoint. Which kernel version are you using? Are you using any uncommon patches? Post the kernel conf...

My kernel hangs for a ~minute at each suspend/resume producing this message in `dmesg`, unless i `rmmod snd-hda-intel` (and lose all the sound I/O of course). Have anyone encountered this?

Re: X210 EC datasheet/better brightness control?

It is challenging to poke the SPI flash with an external programmer: the EC gets powered as well and pulls all the signals the wrong way. It seems like i have to find a level shifter to hopefully power the flash chip enough to talk to me while the EC is underpowered.

Not really an answer to my questions, but https://github.com/erpalma/throttled/ can adjust CPU temperature ceiling and display CPU power consumption (among other immensely nice things) that can be used to tune the battery performance of X210 and other newer Thinkpads.
