Lenovo X Series ThinkPad :: X1 Carbon - How To Re-enable Secure Boot
Aug 19, 2014
On my X1 Carbon, I had to move from Win 8.1 pro to 8.1 Ent. I did a fresh install from scratch to only install what I need.During my setup, I had to disable Secure boot, to boot on a USB Key, install 8.1 Enterprise. Now that everything is working, I would like to re-enable the secure boot option.
If I don't it directly in the BIOS, the laptop doesn't book any more.Do I have to import key from my 8.1 Ent to the Bios or something like this?
I am trying to disable UEFI Secure Boot on my Thinkpad Yoga S1 but it keeps getting re-enabled after a reboot. If I set secure boot to disabled I can boot into the non secure OSes installed on the machine imediately afterwards but if the machine is restarted the Secure Boot seting in the BIOS is re-enabled. It's important for me to have secure boot disabled as I use OSes without secure boot.
I try to disable Secure Boot in the BIOS on the following screen :

But if I re-enter the BIOS either after booting into an OS or simply re-entering the BIOS, Secure Boot is back on:

I have also tried to disable "OS Optimzed Defaults" but it also returns to enabled after a restart.

Some of the other BIOS settings save correctly so I can't figure out why the secure boot settings don't. The BIOS version I have is the latest (1.18).
It's inconvenient to manually disable secure boot each time I want to use the laptop. The two operating systems (Ubuntu and Android x86) do work reasonably well once booted.
It's been a yeah that i work on this X1 Carbon laptop and no default. I got a windows update yesterday, i did it and my computer powered off naturally. This morning, i cant start it, It boot well, Lenovo sign appear but nothing after. only black screen with blinking underscore.
A friend ask me to upgrade her G70-460US Notebook PC to Win 8.1 from Vista. The bios doesn't have a secure boot option and when checking HP the update for this machine doesn't show it either. It this notebook to old to update to Win 8.1? If not where do I find the Bios upgrade with the Secure Boot option?
Yesterday, I updated to win 8.1. The process appeared to go smoothly, but I now have a number of issues:
1 If I close the lid and reopen, the sytem does not wake up. It does not wake up if I press the power button. All I can do is a hard shutdown and reboot. This occasionally gives an error message on restart, but has not produced any solutions.
2 There is a message about secure boot not being configured
3 The support app has a cross on it and won't work
No doubt there are other problems, but number 1 is the killer....
I have a 3 month old X1 Carbon. Last night i turned it off and suddenly today morning, I find that the device is not powering on. What's the deal? No response at all even after continuosly pressing the power button.
My X1 is about 18 months old. It was fine until today. The battery was low, so I plugged it in. The little blue light where the power connects illuminated, however the battery indicater in Windows did not change to show "charging", and the battery continued to drain.
Over the next hour or so I tried many things like shutting down, waiting, new A/C outlet, new power settings, etc. Tried the little reset hole on the bottom of the laptop. Nothing mattered... the little blue light is on, but the battery just drains.
Eventually, the battery drained and the X1 shut down. When I try to boot, I get a pre-boot message about a critical low power error, even plugged in, so my laptop is now a brick.This is a 3448-34U Thinkpad Carbon X1.
I have an AC adapter left over from my first generation X1 Carbon. It is 90W/20V. The adapter that came with the new machine is quite a bit smaller, and only 65W/20V. Can I use the 90 watt adapter with the new model X1, or will it damage it somehow? Dont want to ruin my brand new computer.
I currently have an issue with my original X1 Carbon (2012, 3443-CTU) light not working on the LCD. I attached an external monitor to the laptop and it works without issues so it's not the motherboard. Under the right lighting conditions and angle, i can see very very faintly my desktop background.
This leads me to believe that the screen inverter is damaged, or the lcd. Since my ultrabook isn't under warranty, i believe the best course of action is to find the screen on ebay and replace it. [URL] ....
Is replacing the LCD as easy as it sounds? It looks like i need to remove much of the parts underneath the keyboard panel, and remove the LCD bezel and replace the screen. Is there something i'm missing?
Just got my new x1 carbon, and I like it alot, trackpad isn't as bad as everyone is complaining about. However one big issue is that I want to keep the Function row on by default, and only switch to the default one with volume controls if I press the FN button to do so. Right now no matter even if I chose not to show the default keys, with volume and cloud and all that, it still comes back anytime I switch to a different app.
Bought a unit with this problem: As soon as I unplug the AC Cord from the laptop, it power off without notice and can't power up the laptop. It seems like the battery is not giving power .When I plug back in the AC, I can press the power button.
One strange thing is that the battery is 100%, state : good. Tried the reset battery so now 3 cycle counts. The thing is that if I unplug the AC cord only from the power outlet to the ac adaptor then the power is still up, the brightness goes down a bit and then power off without notice.
- the battery pack switch - removed battery backup - removed and reset the battery pack
I'm out of options and I would be glad if I can find what cause that "unswitchable thing".
When I plug in the AC adapter, my x1 shuts off right away. I have to reset the time in the bios to get it to work again. This happened right after I changed the keyboard. Now, it seems to be permanent issue. I thought it was an adapter issue but I have two adapters and both work fine.
Have a brand new X1 Carbon running windows 7. It originally came with Windows 8 but had to downgrade to run a necessary work application (which could be the problem). My battery never exceeds 50% even when plugged in for extended periods. Also, I am not seeing any of the "Rapid Charge" that was promoted.
I recently put Windows 7 64 bit Enterprise on a brand new X1 Carbon Model 20A7-CTO1WW and I have a missing unknown device in device manager and when I searched for it I came across nothing for the X1 Carbon I found posts on here for X240. The little research I did I did see someone mentioned it could be the fingerprint scanner. Tried that and it did not work. Also Ran system update and that did not work....
Here is the hardware ID : USBVID_138A&PID_0017&REV_0078
I am trying to install windows 8 from the 3 disks that came with the X1 Carbon. There is no DVD drive and we have no external disk drive, so I need to create a bootable USB for this. The laptop came with windows 7 on it.
It is easy to use DISKPART to ready the USB as a bootable device, but how to I take the data from the 3 DVDs and put it onto the USB so that it works? The first one only has drivers but the OS install is split onto two disks. I referred to a KB article but it was talking about autorun files that are not present on these DVDs.
The DVDs I have are labeled as
(1) Applications and Drivers Recovery Disk, (2) OS Recovery Disk Windows 8 Pro [Disk 1 of 2], and (2) OS Recovery Disk Windows 8 Pro [Disk 2 of 2].
where is the printscreen button on the X1 carbon ? Where is the insert botton ?
The keyboard of the X1 Carbon is non standard compliant. The person who took keyboard classes and efficient at typing becomes inhibited with these changes The End botton is close to the A key which is usually the spot for the Caps Lock
I recently purchased a Lenovo X1 carbon, the weird thing is that the computer functions correctly when the power cord is plugged but when the power cord is unplugged the computer DOES NOT turn off no matter what you do. It restarts all the time. If you plug the power cord you can turn off your computer, but when you unplug it it starts working immediately?
In any case pushed the reset button on the back of the laptop but it didn't worked.
My X1 Carbon started running super slow since last week. The disk C: shows I still have 49.2 GB free space to use. So I think the problem does not relate to the space size. I am wondering if there is any way to clear something in my computer and make it run as fast as before.
I recently received X240 and new X1 Carbon (Gen2) laptops with the 256GB eDrive and am working to set up Bitlocker using Windows 8.1.
On the X240, I followed the steps in another posting here and successfully got hardware AES working (by manually installing chipset on newly installed OS, then installed everything except RST and Bitlocker worked with the eDrive).
Following the same process on the new X1 Carbon, however, I only am able to use software encryption and can't figure out what to do to use the eDrive feature.
Is there a process to follow on the new X1 Carbon Gen 2?
I just received my Lenovo X1 Carbon; it's a very good product and I really like it. Everything is working as expected (fast & smooth) except one thing: laptop works kinda strange with the closed lid
My product code is 20A70037US, I'm running Windows 8.1 Pro.
I've chosen (in power options) that laptop does nothing when lid is closed. Yes, it works but... I'm using TeamViewer to connect to laptop; it works but TeamViewer periodically loses connection and displays message "The screen can't be captured at this moment..", Microsoft installer (I'm installing Visual Studio 2013) is paused (!), and Google Chrome won't render pages (but Internet Explorer works fine).
If I open the lid, all symptoms described above are disappear: installer resumes downloading, Chrome render html pages correctly and TeamViewer works fine (no periodical messages shown).
For me it looks like laptop not in "normal" operational state but kinda under power saving.
I've set power option to "High performance" (laptop is plugged) but it doesn't work.
On my new X1 Carbon, with a new Netgear R8000 router, The X1 will not hold a wifi connection, even 3 feet from the router. There is plenty of signal strength on all 3 channels. It connects for a while, but then the icon turns to "limited", and I have no internet connection. It works with my older Netgear WNDR 4500. Xirrus Wi-Fi Inspector sees the three channels with plenty of signal, but will not plot them. I even tried reducing the maximum rate to 289 Mbps, and it still will not maintain a 5 GHz connection.
I have checked the BIOS settings. Intel Hyper-Thread technology is checked as enabled. When I try to turn on Hyper-V Platform in Control Panel, I am told that Virtualization support is disabled in firmware. I see nothing else in the BIOS menu to turn on. What am I missing?
