Hi, I (carelessly) purchased a N140HCG-GN1 to fit an E14 Gen 3. The screen hasn't arrived yet, but I just realised that it lacks the sub board that the current screen has, so I am in a similar situation to OP. Was wandering if anybody had any luck fitting this screen in the T480, or maybe I should s...

I just compiled it. Anyone has pictures where is EEPROM chip located so I can hardware flash if I brick my machine?

If the x2100 is anything like the x210 you don't need to hardware flash. Coreboot can be flashed via software with

Thinkpad X380 Yoga in very good conditions, very gently used for a couple of months only. The battery only underwent around 30 charge cycles and the warranty extends until August 2022. Please note that the keyboard layout is ITALIAN. The machine comes with stylus pen, WWAN card and Lenovo Gigabit et...

I am considering sensible offers for the material in picture (thinking around 600GBP): X210 3rd gen i5-8250U mainboard in x200s (slim) case. Offered assembled as shown without storage and RAM but with an Intel AX200 Wlan card. 16Gb RAM in one module, one slot free for expansion 256Gb NVME Intel AX20...

So I spoke briefly with Xue and showed him the problem. He believes that the mainboard connector might have become loose or damaged and suggested to check for broken connections with a multimeter. Could be an easy fix for someone with the appropriate skills, however I don't have the resources, equip...

So, my x210 started doing this: https://imgur.com/a/ESgI4jz If I move the lid back and forth the picture comes and goes. Happens with the 3K screen AND with the 1200p one, which flickers like hell. That makes me think of a bad connector on the mainboard rather than bad cable(s). What should I do? :...

Checked it today, and in 5.12.6 r8169 still disables ASPM unconditionally with a scary warning: /* Disable ASPM completely as that cause random device stop working * problems as well as full system hangs for some PCIe devices users. */ rc = pci_disable_link_state(pdev, PCIE_LINK_STATE_L0S | PCIE_LI...

And has anyone (successfully) tried to neuter ME on the X210, or do people generally tend to leave it in, and if so why? Yes, the ME can be neutered with me_cleaner during the coreboot building process, people routinely do that. Keep in mind that you don't strictly need coreboot if your only concer...

Also, assuming the pins on the GPIO need to match up with the pins on the BIOS chip (through various clips, cables and possibly adapters), I would imagine there is a left and right, and it matters which way I connect the clip, relative to the pins on the GPIO. How can I know which way is right and ...

Hi yitzhaq, if you only have one RAM slot filled try switching your stick to the other slot. Alternatively try booting with an external screen attached. If nothing works I'm afraid you'll have to hardware flash the stock bios or a precompiled coreboot image. You'll need a SOIC8 clip and a hardware p...

As for the question - well, why not? People (including me) put FHD screens in T430 because they want to (EvanJoo being a godsend here), do tons of other stuff (wifi replacement included), so why not upgrade from AC to AX? Apart from "why not?" - I frequently transfer a lot of data between PCs and r...

The X210 EC firmware directly reports the values it receives from the battery. Most X201 batteries appear to report incorrect values, but it's entirely possible that some third party ones using a different controller could provide accurate values. Ah! I stand corrected then, sorry. I've seen around...

Yes it is, but the readings are all wrong, we apply a correction in coreboot https://review.coreboot.org/plugins/gitiles/coreboot/+/01b6b245f00a3fb498f43c8d59e144c86a51c84a I thought your patches fixed that at the EC level Nope. Out of the box, X2100's EC can't read discharge rate. At all. My patch...

Does your mod work with the X210 too? I think X210's EC is already capable of reading discharge rate from the battery. Yes it is, but the readings are all wrong, we apply a correction in coreboot https://review.coreboot.org/plugins/gitiles/coreboot/+/01b6b245f00a3fb498f43c8d59e144c86a51c84a I thoug...

If you use my modded EC patch, you should be able to get power consumption data directly from the battery.

Does your mod work with the X210 too?

Just did a build as of 3858fb121e4322f7a835b23622bf9452790fcec6, with https://gist.github.com/mjg59/41072100b0799b1e58ec6c9baef25f99 as the config. Works fine for me, other than the firmware splash screen being upside down. Hmmm. Doesn't work. Compiles fine, but doesn't boot. The only difference (t...

Hello all,

has anyone built coreboot for the X210 recently? In the last couple of months I haven't been able to make a bootable build and can't figure why...

The X210 was just merged in the official Coreboot tree

Does the r8169 Ethernet driver provide proper power saving on 5.4+ tho? r8168 seems to be dead now and only builds for 5.3. r8168 builds with 5.4+ kernels with this patch: https://aur.archlinux.org/cgit/aur.git/tree/kernel-5.4.patch?h=r8168-dkms r8169 still doesn't enable aspm, but that can be chan...

You also need to set a custom CLKREQ number to 4. The CLKREQ number is 1 for PCIe port 4, and 0 for ports 1 and 2. Setting this number is a requirement to enable L1 substates. Thank you, it worked! I wonder why wasn't all this the default tho. The stock bios defaults are a little bit.. erratic, to ...

I don't have these. The sata controller resumes ok, and nvme ASPM can be turned on in the bios: you have to manually switch on L0sL1 and ASPM substates for the last PCIe lane in the config. Alternatively you could try the script http://drvbp1.linux-foundation.org/~mcgrof/scripts/enable-aspm After e...

It's been mentioned in Phoronix: https://www.phoronix.com/scan.php?page=news_item&px=Intel-Gfx-DoS-Fix-Hit-Power Apparently, a recent fix for a possible DoS attack resulted in the iGPU not reaching the lowest power modes as often. Ah! That was it, thanks. Easy to revert, fortunately. God I hate Intel

Hello, I'm interested in hearing from people who are using Coreboot and/or the stock BIOS on the X210. Is it me or the last two kernels (specifically the i915 module and firmware) have been completely wrecking power saving on the X210? With 5.3 and the latest v5.4 kernel I get: # turbostat --quiet -...

EDIT2: A different mPCIe USB-C card appears under lspci just fine. So either my M.2 card is damaged or the port is not enabled properly. I'm attempting a return to see if I can claim a DOA replacement and whether said replacement works... Care to share which mPCIe card you are testing? Also, where ...

At a second look, I think the description on 51nb said that the M2 slot under the palmrest is storage-only. xytech might know better.
Are there any mini-pcie style usb-c boards, to go in the wwan slot?

To add USB-C obviously :) And no, it doesn't work on stock either, but then the BIOS has so many options I wouldn't know if it was disabled... I see... :-) Then you'll have to carve a new hole in the case I guess. Where are you going to do that? They don't really make standalone Thunderbolt control...
