ThinkPad T470s BIOS bug - WOL and Thunderbolt 3

Q: ThinkPad T470s BIOS bug - WOL and Thunderbolt 3

It appears that the only way to report a BIOS bug to Lenovo is to post in the Forum (at least that is what hardware support told me), so here goes! Base system:20HF-CT01WW (T470s)BIOS: 1.11 (issue also showed up under 1.10)Windows 10 Pro Edition, Creators Edition, fully patched. Behavior has been observed both on a freshly built SSD (Samsung 960 EVO 500 GB) and on the shipped Samsung 128 GB SATA SSD with the shipped Windows install.Thunderbolt Firmware: n1wth02w.exeThunderbolt Drivers: n1wta10w.exeBIOS Issue related to Wake On LAN and Thunderbolt 3:"Wake On LAN" (Config -> Network) will be referred to as WOL"Thunderbolt(TM) 3" (Security -> I/O Port Access) will be referred to as TB3Using F9 in the BIOS to select defaults and then setting WOL to Disabled and TB3 to Enabled results in:Booting with AC power has no problems. The Thunderbolt port only shows up in Device Manager when the Thunderbolt firmware utility is run - it appears that Thunderbolt ports dynamically attach to the PCI bus only when necessary (i.e. firmware utility asks it to turn on or a device is plugged into the port).Booting with battery from a cold boot (machine powered off for at least 15 seconds) results in a hang with the windows boot time circle of dots cycling endlessly. Powering off the machine at the circle of dots, waiting a second or two, and then powering on the machine usually results in a successful boot into Windows 10.Once the notebooks successfully boots under battery power, restarts are fine.Shutting down the notebook and waiting 15 seconds before powering results in the circle of death hang.Using F9 and then setting WOL to Disabled and TB3 to Disabled results in:Booting with AC power has no problems. Thunderbolt 3 is unavailable (tested using Thunderbolt firmware utility).Booting with battery from a cold boot results in Thunderbolt 3 showing up in Device Manager (use Devices -> View by Connections, look on the PCI Express Bus for stuff attached under "PCI Express Root Port #1 - 9D10"), the Thunderbolt software launches (icon in the notification area of the Taskbar), but the Thunderbolt firmware utility doesn't see the port!Booting with battery from a cold boot and then restarting results in a hang at the initial Lenovo BIOS screen with the fan going to maximum speed.Resetting WOL to "AC Only" resolves the issue.Doing this with TB3 Enabled results in Thunderbolt port that only shows up in Device Manager when the Thunderbolt firmware utility is run (which is believed to be the correct behavior). This behavior is observed both when booting with AC and with battery.Doing this with TB3 Disabled results in a Thunderbolt port that stays resolutely off. This behavior is observed both when booting with AC and with battery.It certainly looks like there is an issue with the WOL setting and that the issue interacts or is involved with the Thunderbolt 3 support.BIOS Issue 2:It does not appear that F9 (Defaults) affects whether "Thunderbolt(TM) 3" (Security -> I/O Port Access) is Enabled or Disabled. I would expect F9 to reset this setting to a default (probably Enabled). BIOS Observation:If you switch "Boot Mode" to "Diagnostics" (Startup page), the BIOS boot screen includes the line "FOR EVALUATION ONLY. NOT FOR RESALE." I doubt this is intended!

HiI just would like a description and confirmation on what the following options do under the Thunderbolt 3 dock in the Bios for this series laptop I tested the option "No security" and this seems to bypass the authentication pop up when logged into Windows when plugging in the Thunderbolt 3 dock. So essentially it enables network ethernet connection to work straight away Can someone tell me what the other options do?

Am running a T470s with a Gigabyte eGPU. Been working fine until I upgraded to the latest BIOS 1.31 the other day, and now it no longer works. The small fain of the eGPU will spin up but the main unit itself (main fan, lights, etc.) will not spin up at all.Thus far I have...1. Checked BIOS settings (No Security)2. Installed/reinstalled Thunderbolt software & firmware3. Downgraded BIOS to the last two versions and back4. Tested eGPU with work laptop & it functions as expectedI'm running Windows 10 but I believe that the issue is unrelated to Windows 10. The reason is, is that beforehand, when the laptop first boots and is still in the BIOS phase, the eGPU used to fire up immediately (lights & main fan). But I cannot even get that, which tells me the issue is not Windows 10 related.Any other suggestions before I go open a support ticket with Lenovo? I'm still under warranty at least.

I bought a Thinkpad Thunderbolt 3 Dock Gen 2 for my Thinkpad X1 Extreme.  I booted up in Ubuntu 18.04 and it wasn't detecting anything connected so upon reading online it seemed clear that I needed to enable Thunderbolt in bios.  I  enabled everything in the Thunderbolt dection, with no security.  After booting up, the system said "Configuring Thunderbolt Controller... Please do not power off".  It stayed like this for 30 minutes and I finally decided to attempt power off but it would not respond.  Holding the power button for as long as 60 seconds does nothing.  I tried closing laptop lid... I tried unplugging thunderbolt... nothing works.

System Specifications:- X1 Yoga (Gen 3) with i7-8650U and 16GB RAM- BIOS Version: 1.19- EC Version: 1.08 Hello, exactly one week ago, I changed enabled "Thunderbolt BIOS Assist" in the BIOS to support Linux.  Following this, the system refused to boot to anything but a black screen.  Thus, I sent the machine in for depot repair.  I just received the machine back again today and the same thing occurred after enabling the same setting.  After a long series of calls, I was told that no one is authorized to report BIOS bugs and that I should post here instead.  I sincerely hope this is fixed, as this is a major error that required a motherboard replacement previously and will most likely require one again.  I have started a new ticket for this repair and will be receiving a box tomorrow.  However, I wanted to make sure this is passed along to someone who can fix this error.

A further reboot without changing anything takes me back to 'None' controller version and nothing in Device Manager. Open to the idea it could be my adaptor has died, I understand you sometimes need a TB3 device connected to update the FW (?) but I do not have any other devices, hoping to try my adaptor on another machine at head office next week to ...

Does the Thinkpad P51s support the Thinkpad Thunderbolt 3 Dock? I have the Thinkpad P51s with stock Windows 10 Pro and updated to latest drivers and Windows version and installed the latest Thinkpad Thunderbolt 3 Dock drivers. Attaching the Thunderbolt 3 Dock to the P51s as described in documentation, it charges the notebook, however, noting attached to the dock is recognized. I've tested with attaching USB flash drives, headphones, Ethernet, HDMI, and DP, but nothing is recognized nor are any warnings/errors displayed in Windows. While the Thinkpad Thunderbolt 3 Dock is listed as being compatible with the P51s and T570, the notebook order page does not list the Thunderbolt 3 Dock in any of the accessories lists. Lenovo Sales also confirmed that the Thunderbolt 3 Dock is fully compatible with the P51s.  However, I needed to purchase the Thunderbolt 3 Dock separately from the notebook order. What's going on? Has anybody successfully used the P51s or the T570 with the Thinkpad Thunderbolt 3 Dock? Or is this something I need to wait for full support via a future BIOS/driver update? Or perhaps my Thunderbolt 3 Dock is defective? Thanks,Boris

A:Thinkpad Thunderbolt 3 docking station does not charge Thinkpad P51 battery.

Everbody's p51 would be the same.  The thunderbolt port won't work as a charging port.  The thunderbolt specs specify 100w max.  That's not enough.  Your thunderbolt port is not for charging.  To charge via the dock, you need a workstation dock, not a thunderbolt dock.  A thinderbolt dock can charge things like an x1 carbon (5th gen) or x1 yoga (2nd gen)

It's not clear to me what 'Wake by Thunderbolt' (hereafter WbT) does and whether or not it's required for 'Wake On LAN' (hereafter WOL).  In the T470s and T480s user guides, there's no mention that WbT is required for WOL so I'm thinking it's not.  But then again, since Ethernet is in the dock itself, and seeing how there are controls for PXE, I could see how it might be required. ReferencesT470s User GuideT480s User Guide

I have since March this machine which is giving me quite a lot of problem. I had several BSOD (or the nicer version Win 10 provides) since several months. I updated even the BIOS. Now it seems related to a specific situation: if the notebook is connected to power supply and goes to sleep.If instead it relies on battery, such issue does not occur. Looking at the minidumps, I notice the main error is always the same PAGE_FAULT_IN_NONPAGED_AREA caused by ntoskrnl.exe + 1640e0 As I use my machine for computations, it becomes really and issue. If I close it and force it to sleep, everything seems OK (or less reproducible events). I made the Lenovo tests and nothing looks wrong. Missing the CD, I do not know how to make a memtest. I read elsewhere that it be related to nvidia drivers, which I do not think concern this machine. I will attach the minidump files. Thank you for your suggestions and help.

Not sure what you mean by you searched for drivers at Lenovo?  Or are you saying you found the drivers but they dont work?  Either way below is the link to T470s.   Click "Drivers and Software" on top.  You can Choose Windows 7 32 bit or windows 7 64 bit.  Also that link will have "system update" as well.  It should pull down all software for your laptop automatically.  Also you metnion T470s but wasnt sure if you had the 20JS, 20JT, 20HF or 20hg models.

Dear community, (please bear with me, I am not an English native speaker.) This is not about the "plugged, not loading" issue I found around here multiple times. My Thinkpad will charge via charger only when it is switched OFF. It loads perfectly when plugged via docking station.Batteries are getting empty, power save mode and all that. Pluging two different power units show same result. Behaviour, reproducable:Computer running, info tray says battery 1 in use and battery 2 not loading (or vice versa), no matter if charger is plugged or notWhen charger is plugged while PC runs, the charger indicator light right besides the power plug remains darkOnce my ThinkPad is truly off (shutdown), any of my chargers work just perfectly: orange light while charging, green light when finishedAdditional weirdness: ThinkPad does not start when plugged to the charger. Hitting/pressing the power button at the right of the keyboard has no effect at all. Once unplugged from charger, it boots just as usual. While typing this with 9% remaining capacity, computer shut down. I plugged it to the charger and closed the lid --> orange light. Waited a couple of minutes. Opened lid. ThinkPad wakes up, and I continue writing.Again: charger is plugged, LED light is off again, info tray says not loading/in use. Any ideas?Frederik I am running M$ Win10 Enterprise.

I have a Thinkpad T470s Windows 10 pro 64bitI enabled bit locker a month ago everything was fine.Now last week everytime I boot up my Laptop, Windows 10 keeps asking for the Recovery key. I typed it in suspended bit locker. Shut down then turned it on but still keeps asking for the key.There is no new hardware on the laptop and has the latest bios.TPM 2.0 is enabled.Boot priority is ATA HDD0 SSD drvieUSB HDDNUME0USB CD In the bios under SATA drive is set to UEFI/Legacy Support for both -UEFI and Legacy.As a test I tried setting to UEFI only and Legacy one but Bitlocker still keeps asking for the Key during the bootup.For now I turned off bit locker until as solution could be found.If anyone has a solution would really apperiate the help.

Good day and welcome to the community.

Hope it has some clues for you.

My new Thinkpad T470s has a backlight keyboard.  The User's Manual indicated that there are four backlight modes: Off, Low, High, and Auto.  However, pressing Fn+Space key would cycle through Off/Low/High modes only.  Any suggestions on how to turn on the "auto" backlight mode?

Hi,
 
Check the Lenovo Settings app. IIRC that's where the auto option is available.
 
I don't have LS installed on the ThinkPad I'm typing on so can't tell you exactly where.

Hi Guys ! I have been getting this error for a while now. Since august I think. It happens very randomly and I don't know what triggers it really. I tried to put another m.2 and it worked perfectly, no errors. But with the factory m.2 I get this error and I never got the way around to fix it. When I first got this error I barely could start my computer. 9/10 times I got the error and I couldn't start the computer at all. I replaced it with another m.2 and worked fine until I decided I wanted to put the factory one again ( because it has twice as much storage ). Now I still get the error but rarely. Casually. In very random situations. I still find it very frustrating and I was hoping someone has any solution. Thanks and have a nice day
