Lenovo X1 Carbon 2nd gen - Won't POST or boot after BIOS update 1.35

Q: Lenovo X1 Carbon 2nd gen - Won't POST or boot after BIOS update 1.35

Greetings, I've been a happy owner of the following notebook. Yesterday after using Lenovo Vantage I got info that a new BIOS is available 1.35. I updated, the system rebooted, it was all fine and working. I eventually turned off and rebooted the laptop a couple of times during the day and still everything was fine, until later that day in the evening I put the laptop to sleep (closing the lid). After trying to wake it up I got a cold shower. - The screen doesn't light up- There is no POST or boot picture at all- The Keyboard backlight lights up and works- The adaptive touchbar works (and cycles thru the two menus)- The fan spins for about 5 secs after power om The things I have tried so far: - Connecting to an external monitor to see if there would be any activity - no signal- Tried pulling out the battery and draining the system (holding power button for a minute)- Tried the reset button. Unfortunately nothing worked, and im stuck and in need of assistance. Thank you in advance for your kind advices.

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

This morning, I'm working on downloading available BIOS updates related to Meltdown/Spectre, and creating bootable USB keys with the updates for each model computer that we use.  I've downloaded the update for the 20BS from here: https://pcsupport.lenovo.com/us/en/products/LAPTOPS-AND-NETBOOKS/THINKPAD-X-SERIES-LAPTOPS/THINKPAD-... According to the readme file, this update should include a tool for making a bootable USB key to install the update, but the tool and the "Instruction US - BIOS flash USB memory key.txt" file referenced in the readme both seem to be missing from the download.   Please advise how to create a bootable USB for installing this bios update.

Hello,
I am having problems with direct booting into Windows 8 installed into a VHDX file.
This is a four-partition UEFI boot on a GPT drive. EFI files are residing on a second partition of disk 0 (the ESP partition) in the EFI folder. The boot virtual disk is residing on the fourth partition of that disk 0.
When I turn on the PC, it shows black screen after the BIOS POST screen. No Windows 8 boot menu, no other information is displayed. However, if I press Shift+F12 (or F12) to start Dell BIOS Boot Menu and choose Windows Boot Manager from the UEFI part of
the boot menu, Windows 8 starts to boot without difficulties.
How do I make Windows to boot automatically without having to select Windows Boot Manager in DELL BIOS boot menu?
I believe I messed up with boot sector somehow... What needs to be fixed provided that Windows 8 will boot into VHDX file?
Thank you.

Well this is the world we live in And these are the hands we're given...

Hello all, this is my first time posting here so please forgive any mistakes/oversights. I've just updated my Samsung laptop's system BIOS via their software update program, and my Nvidia GPU (GT 650m DDR3) no longer seems to work. The Nvidia control panel is still there, and it still gives me the option to select which programs use the GPU, but there is no GPU actitivity showing up. Also,I've tried playing Skyrim (which auto-detects the PC's graphics cards) , and the game no longer seems to detect the Nvidia GPU (just the Intel integrated graphics).

My laptop model is NP550PC7, with 6 gig of ram, and an i7 quad core CPU, and the OS is Window 7 Home Premium 64bit.

I've tried looking in the BIOS but I can't seem to find anything related to the GPU or display options. Any help or avice is much appreciated.

Hi,

Have you updated your GPU with the latest drivers?

Please navigate to:

Start> Control panel> Swith to icon view> device manager.
Look under "Display Adapters"

Is the Nvidia GPU listed there? If so are there any yellow symbols etc?

About three weeks ago I upgraded BIOS on my laptop (as suggested by Lenovo Vantage) to latest version (N14ET45W (1.24), 3/01/2018). I am running Windows 10 64 bit. Shortly after that I started suffering quite frequent momentary freezing events where I had to wait between 10 to 40 seconds for the machine to continue working. During this period many of the running apps were closed and then reopened and I could not type or do any other thing. As you can imagine, this turned to be quite frustrating. I started searching at several forums, mainly Windows 10 related forums for a solution. U tried every possible solution, from updating all drivers to editing Registry etc. with no positive results at all. I was finally considering a full reimage of my machine when my latest resource turned to be rolling back my BIOS, as after checking on dates it seemed my suffering started shortly after my latest Lenovo Vantage drivers and BIOS update. Accordingly, I rolled Back from indicated BIOS to N14ET45W (1.23), 2/28/2018.Voila! This was the required solution. After that, my machine has been running smoothly, with no freezing events.Hope I had found a solution at any forum, and that?s why I am sharing this information here, as I really spent almost three weeks of frustration and unsuccessful searching/testing. I think Lenovo should test better and BIOS release. Hope my post may help other X1 Carbon 3rd Gen with a similar issue. DO NOT UPGRADE BIOS TO version (N14ET45W (1.24), 3/01/2018!!... Read more

Hello, I have a ThinkPad X1 Carbon 3rd generation. Two days ago, I have updated the BIOS to the latest version 1.12. The installation went well and I successfully booted into Windows 10 with no issues. However, the fan was not working anymore. I did not notice this until the laptop was extremely hot (which is very unusual for this laptop under low/medium load). In particular, I was just running a "disk cleanup" using the native Windows tool and after 5 minutes I decided to kill the process (this operation usually takes 1-2 minutes). My feeling was that due to the temperature the cpu was in throttling. At that moment, I noticed that the fan was not active. After a shutdown, the fan was again working. However, I noticed that the fan kicks in much more often than it was used to. For this reason, I did two things:- I have downgraded the BIOS to 1.11: BIOS 1.12 updated the CPU microcode, I am not sure that the microcode was downgraded as well when I downgraded the BIOS. - I have run the "Intel® Processor Diagnostic Tool": I was afraid that the high temperatures may have damaged the cpu. The tool reported that the maximum temperature of the cpu during the benchmark was always safely within the expected threshold and all the tests were passed. Now, I still can see that the fan kicks in much more often than usual. I have noticed, using sensors under Ubuntu 15.10, that every time there is a very short burst/peak of... Read more

Hello, I just recently performed the 26-Jul BIOS update to 1.14, for my Thinkpad Carbon X1 (20BS) with windows 10.The update went ok, but afterwards, Windows is crashing when booting. Using a bootable Windows 10 installation disk also crashes when booting. The recovery environment also crashes when booting. Using detailed logs, it seems to crash when activating the ACPI microcontroller. I would assume that has something to do with the UEFI update, that I have disabled in the BIOS. Enabling it does not recognise the disk, as it is not a GPT partition. I tried to rollback the BIOS, but it does not allow it.  Do you have any suggestion on how to proceeed? Thanks,Pedro

I created a new USB stick and reimaged the machine. At the end of the installation I was interrupted and left the laptop for several hours. When i returned it was off. Now, when I press the power button, the keyboard lights flash, and the screen shows the Lenovo logo and briefly the message "To interrupt normal startup, press enter". Then turns off. I have tried:  - During boot, I have tried pressing enter, pressing F1, F2 and various combinations- Tried the power reset using the paper clip in the hole at the bottom.- When I press F1 repeatedly during boot, the computer beeps and says "Entering Setup" very briefly (so fast it's hard to read), then turns off- tried booting to USB sticks Other than the repeated pressing of F1 which shows the "Entering Setup" message, nothing has any affect, and the laptop just shuts down. Any advice?

I had the same problem.If you have windows installed, do not shut it down normally, but make a hard reset (press for a few seconds the turn-on button). It looks like Windows Computer (WC) does not really shut down so you miss the chance of entering the BIOS.To me it works by then pressing the F1 button (without any extra Fn or Ctrl, etc..) a few times after pressing the turn-on button again (no need to press them at the same time).Btw., if you want to install GNU/Linux and boot from USB, you may need to change this in the BIOS: _security _disable secure boot, and_startup _UEFY legacy -> both My system: Win10 (now Debian), X1 4th generation, PCIe SSD

Yesterday I got some drivers updates along with BIOS update. BIOS seems to update successful (now its 1.14), everything under BIOS works. I had 2 OS: win10 and Ubuntu with grub. I've been a happy user of all these for several months, but... The problem is that after some driver update (which was done via Lenovo utility for Win10) I cannot boot any OS nor any OS installation even! Recovery ISOs, diagnostic tools... Nothing can be booted. BTW, I know how to deal with Secure boot and legacy mode. I can manage to start the boot process of anything listed above, but they all behave the same. They freeze in the very beggining. Everything which involves ACPI just hangs on boot. Linux hangs after message "ACPI tables successfully requested" or smth like this. Win10 displays dots which go round 1 second and then hangs. If I add "acpi=off" to Linux boot options, it boots (but almost nothing works there without acpi support). Things which don't require ACPI work. For example, I can boit BIOS update ISOS. Still it does no help as my BIOS version is the latest and it doesn't allow to rollback. It can't be hardware problem as it occured after Windows updated drivers and flashed some firmware (not BIOS, but I don't know what it was exactly). I can access data on SSD and can see some logs if needed. Hope for assistance How to flash again all possible laptop firmware from boot USB? What can be flashed except BIOS?

If I press any button laptop wakes up and all things are working great Until Restart when same loop occures.Trying upgrade bios from v1.07 to latest V38 (2.06) but as soon as insyde flasher starts flashing bios (erase/write) windows is restarted (without allowing flasher to finish I THING) causing the same loop to occure. After many restarts without proper post a message appear which states that the bios was not correct for that model. If I press any key to reset after many reset loops I concluded with window in stand by mode again. Any Suggestions for a propper bios Update which I think is the problem ? ? ?

Hi,
Sorry first time poster. I wasn't too sure whether to post to the Windows forums or hardware forums. From what I can see, this seems like a hardware issue of some sort.

The problem I have is that during bootup my PC goes through all the normal things. It detects my CPU, detects RAM etc. gives me nice BIOS Post messages that appear normal and then goes to a black screen. It will then sit there for 50 seconds (i've timed this twice) and then proceed to go to the windows XP startup screen (which takes about another 10-20 seconds to load up windows).

I've attempted to log the bootups by using the Windows Boot logger (by pressing F8 before windows boots). The ntbtlog.txt file isn't very descriptive, and only lists that a whole lot of drivers have been loaded, and some that haven't (it doesn't list any errors).

I've also tried using BootVis to analyse the bootup. I found this a little hard to decode the information it gave me, but there doesn't seem to be anything untoward happening.
The last boot logger I tried was bootLog XP (by greatis software). According to bootlog XP, windows is only taking 19 seconds to load up.

Can anyone suggest any other ways to analyse the boot sequence and discover where my computer is stalling?

(specs are below.)

Thanks in advance,

Matt


CPU: AMD Sempron 3000+ Socket 754 (unsure whether it is Paris or Palermo core)

I recently updated my BIOS to 1.40 and discovered that with no page/swap file in Windows the BIOS update hangs on shutting down the system. After forcing a shutdown by holding down the power key shows and booting, the Lenovo System Update history indicates the BIOS update has been completed, but MSINFO does not show an updated BIOS. Once a swap file has been created and the System Update is rerun, the BIOS update completes successfully. My X1 model is 20FB and the OS is WIn 10.

So I've messed around with this my whole afternoon.What I've found out is that the X1C I just got will not notice my monitor (samsung px2370), however, it will notice my TV just fine.Figured I would try a BIOS update...well I already have Linux installed and the BIOS update options are "Windows" or "CD"...why...there is a CD/DVD option...in 2018...on a model that does not have a direct CD/DVD drive - is beyond me.I've tried copying the iso image with 'dd' and booting from it but that doesn't work.Suggestions?

Sadly I installed the [now withdrawn] GRET54WW (1.31 ) BIOS update which patched the Spectre vulnerability on my X1 Carbon 20A7 model a couple of weeks ago. I've since been experiencing spurious reboots when coming out of sleep and random BSODs --- which are obviously the reasons for the update being withdrawn. Is there a way to downgrade the BIOS to a prior level? Not sure that I can live with this until 3/31/2018!

A few days ago I was prompted to install an urgent BIOS update.  I followed the screen prompts and the system rebooted and flashed the BIOS.  Our company laptops all have Sophos encryption, which requires a separate login prior to booting the OS (Win7).  I've always been able to enter user ID and password information on that screen using the USB keyboard connected to my OneLink+ dock (which is connected to the laptop). Following this BIOS update, I can no longer use the keyboard or mouse (also USB) connected to the OneLink+ dock until the OS boots.  I have to open my laptop, enter my Sophos ID and password on the laptop keyboard, then close the laptop.  Once the OS (Win7) boots, I can use both the USB devices fine.  Interestingly enough, the monitor attached to the OneLink+ dock functions just fine before the OS boots up. I checked BIOS settings and couldn't see anything there that looked odd or out of place.  I also checed Device Manager to see if there were any warnings or issues, and didn't see anything. I tried to downgrade the BIOS to an earlier version, but once you are above 1.23 that is not possible.  I did flash to the latest release - 1.27 - but that did not fix the issue. So I'm stuck with a rather awkward login process which was not an issue until this BIOS version was installed a few days ago.  I've reviewed other post for similar issues but have not found anything that points at a solution thus far...

Took my X1 Carbon on vacation with me in Thailand.  Used it once.  Tried to boot it the following morning and a message about something missing - in courier font without a screen driver.  Now it will not boot even into just the bios.   Press the power, and the power button lights up, the keyboard function selection is active and can be toggled through, the keyboard can backlight, but nothing else.  Then a short time later it shuts down on its own.  I have tried powering it on and using a paper clip to press the reset button.  Any ideas?

Is your warranty still active?  This would be a good time to use it.

Hello everyone! I ama new user and i am coming up with this post as I couldn`t find any kind of solution for my problem.Recently I decided to do a reinstallation of my operating system, which also previously was Windows 7 Ultimate (x64). The installation went as usual, and after finishing it I went on to install all the latest drivers from the Lenovo site, for my product. When getting close to installing almost all the drivers i`ve needed, i stumbled upon a new version of the BIOS amnd the drivers and sfotware recommended for my laptop, by the producer. So i proceeded to install the upgrade, restarted the computer when it prompted me to do so, but after the so-called restart the laptop did not boot up as usual. At first it was telling me to not do anything as the BIOS is being flashed and then it was telling me something about some sort of image processing, things that i did not understand at the time (i have never encountered anything like that). After that my screen turned black. I have not done anything for a few couple of minutes as i thought it was supposed to be like that, but then i just force shut it down and unplugged the AC adapter. When trying to boot it all up again, the only thing i got was a black screen and nothing else.After doing a little bit of research it appears that, somehowm i`ve managed to corrupt the bios on my laptop or something, and nothing else would work at this point. I tried to remove the BIOS battery and the ram and then put them all back, trye... Read more

I?m currently updating the BIOS of some Lenovo ThinkCentre M83 PC´s and I came across a problem. The Flash UEFI BIOS update (provide by Lenovo) worked almost perfectly on the first PC´s, despite it didn?t automatically open the console and started the flashing process.Anyways I did go on with my work. Almost all other PC´s had the problem that when the second phase (yellow font)/ afudos.exe imagefb.rom /defans /capsule /b /n /r /sp started the afuwin.exe stopped working (it crashed). It seemed like the Update wouldn?t get done this way so I decided to try it with the USB Flash method, also provided by Lenovo, but it also didn?t work. It says in the second phase ?15 - Error: Secure Flash function is not supported on this platform? Last but not least I tried to update the BIOS with the CD-ISO but when updating with this method it says that the BIOS-Version is too old. Some information about the system: ThinkCenter M83Type: 10BE0003GEOS: Windows 7 SP1 64bitBIOS-Revision: FBKT73AUSBIOS last Updated: 01.April.2014 Furthermore Information what I found out:BIOS-Revision seems to not matter (same version but some worked some not)Doesn?t matter if BIOS is set to UEFI only or Legacy onlySecure Boot also seems like it doesn?t matter if it´s on or notWhen the afuwin.exe crashes it only writes a return codeI use the update provided by this Page from Lenovo (Update: fbjycpusa)https://pcsupport.lenovo.com/de/de/downloads/ds035753 Thanks...
