Re: X210 EC datasheet/better brightness control?

Is it possible to set the bat thresholds with EC? If you want to undercharge the battery to prolong it's life, then it may be done already. :-) At least my laptop is constantly undercharging the battery by several parcent. My X210 charges the battery to 4.16 per cell, while ~4V ceiling during typic...

Re: X210 embedded controller fixes (was: X210 EC datasheet/better brightness control)

I've brought up some infra for comfortable patch selection and application: https://github.com/l29ah/x210-ec
It would be cool if you submit your patches/pull requests to avoid throwing lots of differing and poorly documented blobs around that bring a lot of changes and are a pain to merge.

Re: X210 embedded controller fixes (was: X210 EC datasheet/better brightness control)

I get 3.8W on lowest backlight and associated wifi. 3.5W with deassociated. All the ASPM is enabled, but i still never reach pc9 and pc10.
Out-of-tree r8168 module is necessary for ASPM support.

Maybe your CMOS Setup settings are not optimal.
You're right, ASPM was disabled for all the PCIe interfaces in BIOS, thanks.

Re: X210 embedded controller fixes (was: X210 EC datasheet/better brightness control)

No. The EC just reads a temperature and sets PWM. It has nothing to do with throttling. See code: Silly me, of course throttling is done by other means. But nevertheless it's really fishy that sensors jump from 7*->100*C. Something is wrong here, and I don't know what is responsible for this, as ea...

Wired, not wireless. Network manager somehow enables powersaving on wired network even when the interface is up, but there is no connection and reenables it after waking from suspend.

If so, let's take a debug log: # echo 4 > /sys/module/drm/parameters/debug $ xset dpms force off Wait some time, hit any key to wake a display, post part of dmesg after enabling logging here.

It looks, like you have updated a kernel, but forgot to patch the i915_psr.c to force-enable PSR.
Nah, i'm running the patched kernel.

They're great at designing the circuits and motherboard though.
I can't call a diode on the battery power input and the lack of the keyboard drain hole on the MB great.

Re: X210 EC datasheet/better brightness control?

Can't you just wipe your ME firmware for sure with me_cleaner? Short answer:NO. Long answer: I could and it's possible that this would remove the preinit hang, but it's a bad idea to remove ME in general. ME inits the MRC cache and some other timings, so this can induce some problems later. I'd lik...

Soldered an additional heat pipe to my X201 cooler. Got only ~13% more power at 10 minutes than the stock config. Is 13% not enough?

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...
