Lenovo ThinkPad Yoga S Series :: Disabling Secure Boot On S1
Nov 16, 2014
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.

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?

is there any possibility to make boot from SD Card on Lenovo Thinkpad Yoga?
I have live linux image, but there are no optical drive on system, so I would be glad to use the SD Card slot. When start with boot selection, there no SD Card slot listed even if I have the bootable SD Card inserted into. On other system the same card booting properly.
Are there some bois settings to allow booting from SD Card slot, so it will be included in boot device list? The same system boot from USB, but USB consume one USB port, so the SD Card is more preferable option.

I just purchased a refurbished Thinkpad Yoga, and all was great for a little while. Then I decided to shut it down and set it aside for a few minutes.
Current Status: System responds in no way other than the 'i' light (in the Thinkpad logo) blinking three times when the charger is connected, or the same when the reset button is pressed while the charger is still connected. Nothing else illicits any sort of beep, light, or otherwise.

My computer doesn't seem to start up anymore. It only enters the "Boot menu" tab with no further information. When I'm trying to press "Enter" it just returns back to same screen again. Is my harddrive broken? Is there some reset button available anywhere on the device?

I have a Thinkpad Twist. I started it up and got a thermal sensing error before the boot screen. I looked up the error on various forums, tried turning it off to see if the message would still be there. When I rebooted it, it went away. Should I still be concerned for the fan or CPU?
My laptop has been overheating before this, but it's never shut itself down, even after the error message.

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....

Is there anyway to disable the center scroll button on the x-240 trackpad. I keep hitting it when I try to use the left mouse button. I never use the scroll button and want to get rid of it. The new trackpad's design is horrible with the undefined buttons.

I've got the 12inch thinkpad yoga. The left shift key works intermittently. This started happening to me a couple of weeks ago (I've had the computer since December and haven't noticed a problem. I sent it in twice and supposedly, they replaced the whole machine this last time, but I'm still having the problem. Could this be a fault in this model in general?

The label on the charger says:
MODEL 45N0261
FRU P/N 45N0262
Lenovo P/N 36200253
It was advertised as X1 charger, but when it arrived I thought it's too small in size, so I googled it. Having done that, I've realised it's actually being sold by Lenovo as a charger for Yoga.
Am I safe to use this charger for my ThinkPad X1 Carbon (3460-CLG)?

Is there a possibility of installing a 3G/LTE module on the Thinkpad Yoga? To my understanding there is an m.sata slot on the Yoga that allows for us to put extra SSD hard drives on it. Is it possible to replace it?
If not, are there other methods other than using usb-dongles or hotspots?

two days ago my Lenovo Twist S230u laptop started to freeze a lot, especially when I tried to multitask (like switching to a separate window). It probably took ten minutes each time for the computer to unfreeze and continue.
the in-built 'Lenovo Solutin Center' software ran an automatic diagnostic test, and said that the laptop failed the SMART short-self test (unfortunately I forgot to copy the error code). I didn't think much of it at the time since my laptop is only 5-months old. Just in case, I performed a disk cleanup, disk defrag and made sure everything is up to date. This was when the laptop began to freeze quite a lot. In desperation (and stupidity), I typed the chkdsk /r command in command prompt and asked it to run at reboot. Apparently the SMART short self test is a physical problem rather than a software problem, so obviously chkdsk won't work.
chkdsk ran for about two days now which is clearly too long for a 500gb HDD laptop. I've only used about half of this space too. I forced a shut down and now I cannot access Windows 8.1 through the boot menu (it just hangs on a black screen). Loading a rebootable USB recovery drive is not doing anything too.
I previously sought support on the Microsoft Answers website. They said that my 'hard disk is failing' and I will need to have my HDD replaced.I just want a second opinion here. Is warranty valid under this circumstance? From what I remember, 'Lenovo Solution Center' said I still had a few hundred days of warranty left on the machine.

Some texts look blurry on some windows. I have attached a picture to show you what I mean. If you see "Device Manager" window, the text is blurry. On the other "System" window, the text is just fine.

I have S430, bios 2.58 I decided to upgrade my HDD to SSD and install clean Windows on it.
I've downloaded Windows 7 ISO from [URL] ....
Then I have loaded it into Windows 7 USB DVD Download Tool
Prepared with that app bootable DVD and flash
First I tryied to install Windows from usb, installer runs and asked me for CDDVD drivers. I sat up USB3.0 to disabled, then in browser window I can see my flash, but the message about drivers remains..
Also I copyed USB3 driver from [URL] ... to another flash and tryed to give them instead of CD-DVD drivers, but they are shown as "not compatible"
Next i tryied with DVD, but I can't even load installer - DVD begin to roll, but then shows me "choose boot device" dialog. Secure boot is OFF, UEFI tryied both Legacy Only and UEFI only....

I have had this laptop for 7 months now, but since about 4 weeks ago when i click on shutdown i realised that it looked like it was shutting down... and 30 seconds later would fire up again. At first i thought it was me clicking the wrong button, but it has happened daily now. Only way to shut it down is my removing the power cable and then shutting down.

S440. I prefer to use the function keys F1-F12 without using the Fn key. It seems like in other models there is an option in the BIOS to change this, but not on my machine. Also the Lenovo software nor Windows configuration seems to be able to change this. Is there anyway to do this?

I only bought the one link pro to connect my Thinkpad Yoga 2 to my Samsung monitor with WQHD-Display with 2.560 x 1.440 Pixel. Lenovo told me that this is possible. With DVI I only get the maximum 1920 x 1200 which makes round circles look like eggs...
I need the full resolution.
I there any configuration, cable, display port instead of DVI cable?
(I have the newest, best, DVI cable (forgot the specification for high resolution DVI cable, ports)).

I just flashed BIOS on my thinkpad yoga 20CD00B1US. I got the lates BIOS 1.18/1,09 and sice this flash, I cannot make any changes in BIOS. I can list in BIOS but cannot highlite and change any setting expect quick boot Enabled/Disabled
My even manager is reporting me this warrining: : The embedded controller (EC) returned data when none was requested. The BIOS might be trying to access the EC without synchronizing with the operating system. This data will be ignored. No further action is necessary; however, you should check with your computer manufacturer for an upgraded BIOS.
I do have set up supervisor password for BIOS, password on power on. When going in BIOS, I am not asked to put password in, which could be the issue.
