Will X220 ever get a BIOS microcode patch for the Spectre?

Q: Will X220 ever get a BIOS microcode patch for the Spectre?

https://support.lenovo.com/tw/zh/solutions/len-18282 In this official support page of Lenovo, the X220 is not among the listed machines. I think there are still a lot of people out there using this xx20 series laptops(X220, T420..), will lenovo ever release the BIOS update for this laptop?

Preferred Solution: Will X220 ever get a BIOS microcode patch for the Spectre?

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.)

According tohttps://www.intel.com/content/dam/www/public/us/en/documents/sa00115-microcode-update-guidance.pdfThere is a microcode patch for the Arrandale i5-520M out there. As of yet this patch is neither in intels linux microcode archive (latest version in there is 0x4 which is years old)https://downloadcenter.intel.com/download/27945norin the Windows Update cataloghttps://support.microsoft.com/en-us/help/4090007/intel-microcode-updates I have scraped vendor sites for other laptops that shipped with that processor. A few of them had recent Bios updates with microcode patches. Especially the Panasonic Toughbook CF-31. I unpacked all of those bioses and the microcode was only for later CPUs not this one. So no luck there either.I contacted Intel support and they told me if its not in their official downloads then I have to ask the OEM. It was acknowledged that this patch exists and was shared with OEMs but the person on the other end was not allowed to give me any more Information. At Lenovo it seems all Arrandale Laptops are EOL now, so no new bios updates.Still that machine is pretty useful for me and I'd like use until it turns into dust. Afaik 20655 was used in Thinkpad X201, W410 and T410 which are EOL So if there is no kind stranger out there that can provide me this file somehow I have to give up on that matter. Does anyone of you forum users have more Info?

Lenovo please update the BIOS for your older PC with the available microcode from Intel to help avoid Spectre.  When will Lenovo add Sandy Bridge based Intel cpus, and many others, to the list of products at "Reading Privileged Memory with a Side Channel" linked here https://support.lenovo.com/gb/en/solutions/len-18282 I see Intel have already released new microcode for Sandy Bridge cpu's to mitigate Spectre and many other cpus.  See the long list here https://downloadcenter.intel.com/download/27431/Linux-Processor-Microcode-Data-File Lenovo need to post far more target dates for BIOS updates, with the new microcode, beyond the recent PCs listed!  I see HP are ahead here, they have aready published dates for their products using Sandy Bridge cpus.  See this link https://support.hp.com/us-en/document/c05869091  Several HP products on this page use Sandy Bridgde cpus and already have target dates for new BIOS/microcode.  For example the HP Compaq 8200 Elite gets new BIOS and microcode on 19th Jan 2018 - well done HP - a very simlair business class PC to the Thinkcentre M91p.

Hi! Recently Spectre fixing BIOS patch F1KT73A was released for ThinkCentre Edge 72. Web page and change history states that only Ivy Bridge microcode patch was included.So, what about Sandy Bridge? We have different models with Sandy i3-2130 and with Ivy i3-3240.According to Intel's Microcode Update Guidance, Sandy Bridge fix was released too. Are there any Lenovo plans to release BIOS containing both Sandy and Ivy microcodes soon?We just want to protect all our workstations, not just half of them...

Just posting here because I have a Toshiba Satellite NB10t-A-101 and after running the checker tool available on the net regarding the machine vulnerability against Spectre and Meltdown, I am concerned by Spectre.

Here after a link to another thread where I arrived after a search.
I include a link to a Toshiba page with some information on that critical subject.

Seems there is, as of today, no schedule date for my machine.

Greetings, I have many M82s in my organization, a little over 4 years old. However, I am not seeing M82 listed on the Lenovo support page here for the products that do/will have the microcode mitigation for the Spectre vulnerability CVE-2017-5715. Does that web page contain the complete list of products for which firmware will be updated? Or will older models be added? I am hoping that Lenovo will continue to support products that were sold in the recent past, such as M82s and perhaps even some earlier models, particularly for PCs that are targetted to businesses.

The spectre microcode update (KB4090007) contains microcode updates for most modern intel cpus. 

The Broadwell-E family of CPUs (6800K, 6900K, etc) with CPUID 406F1 is NOT listed in KB4090007, and the update in the catalog reports "not applicable" when attempted.

Intel released microcode updates for Broadwell-E along with the other CPUs, so I'm curious why it would be excluded from KB4090007.

Is the Broadwell-E omission intentional or accidental?  The CPU is reported to be vulnerable to spectre.

Thanks for any clarification you can provide, or correction to KB4090007.

I have installed the "pulled" BIOS update for Spectre/Meltdown, and now have significant stability issues. There are no instructions on this page of how to rollback this update: https://support.lenovo.com/us/en/solutions/len-18282 In this situation, does Lenovo advise re-installing an older BIOS? Or is there a solution coming very soon? It's been several week without any updates.

A:How to rollback withdrawn BIOS (CPU Microcode) Update? - T550 BIOS 1.19

Downgrade to older BIOS version will not help, as installer won't be able to downgrade CPU microcode. Currently Lenovo and Intel are working to provide a solution which allow downgrade to previous microcode. They have adviced to wait till downgrade method will be developed. But... you can do something to restore stability of your system. It was found, that stability issues are present, when OS is using fixes against meltdown/spectre. Actually, you can disable them. Below you'll find a guide:https://winaero.com/blog/disable-meltdown-fix-amd-cpus-installing-kb4056892/ Personally, I've tested it on few devices and stablility issues were no longer present.

Hello Lenovo! I expected to see a new BIOS-Update for my X220 at end of february: https://support.lenovo.com/de/en/solutions/len-18282 I was glad to see that, because Intel is just unable to make any clear statement and refuses to fix older CPUs. This is now removed, without a notice! Dangerous security issues must be always fixed, there is not out of support in general. Despite that, the X220 was sold till 2013 and 2018 is in the ususal five year warranty range of the ThinkPads. Can you tell us please, what is going on? I hope you will follow your own path of good support and not Intel. Interestingly there are still listed Microcodeupdates for SandyBridge (Server), same architecture. Thanks

Hi, the changelog of the BIOS 1.29 states that it contains an update of the CPU microcode.Afetr I upgraded successfully to that new BIOS, I've been surprised to notice that the microcode wasn't updated.Booting on lunix, I can see that the CPU is still running the old revision 0x24 of the microcode: [ 3.081408] microcode: sig=0x306d4, pf=0x40, revision=0x24
[ 3.081446] microcode: Microcode Update Driver: v2.2. I expected to find the revision 0x25 which was released by intel several months ago (see: http://metadata.ftp-master.debian.org/changelogs/non-free/i/intel-microcode/intel-microcode_3.201705...) By comparing the line below extracted from that link to the boot message I reported above, you can verify the CPU signature and the processor flag mask associated to that microcode update perfectly match my CPU. sig 0x000306d4, pf_mask 0xc0, 2017-01-27, rev 0x0025, size 17408 So I wonder why that micocode update was not included in the BIOS 1.29.Is it a mistake ? or did Lenovo have a good reason to omit it ?

I have several dc7800 (2 SFF & 1 CMT) I would like to update the BIOS & Microcode so I can upgrade the processors to the supported Q9400 CPU's I have sitting here. Can somebody help me on the process to upgrade the BIOS & MicroCode?  

A:dc7800 BIOS & MicroCode Update

Hi: Here is all the info you need to update the microcode for your dc7800's. Files are the same for the SFF's and CMT's. You have to copy the DOS flash files in the microcode update folder to a bootable usb flash drive, with DOS command files on it. Put the flash drive in the PC, turn it on and the PC should boot to the usb flash drive. At the command prompt, type Flashbin.exe and hit the enter key. Follow the on screen instructions to update the microcode. I zipped up and attached the utility to make a bootable flash drive below, the DOS command files you need, as well as the dc7800 microcode update files. You make the bootable flash drive first by running sp27608. After the utility has formatted the drive and made it bootable, copy the dos files to it, then copy the Microcode update files to it. Copy just the files in the folders, not the folders. After you update the microcodes, I will give you the instructions to update the BIOS.  I don't want to confuse the attached microcode files with the BIOS files. So, you can let me know when you have completed that process. Updating the BIOS will be easier.

Hello. TL;DR version: I think that BIOS 1.34 update for X1C6 botched the CPU microcode or something, which causes severe power drain, and I wish to contact Lenovo. Long version (I'll try to make it short): My system is:X1 Carbon 6th Gen (20KH)Core i5-8250U / 8GBWindows 10 ProBattery at full capacity (bought the laptop in October, the battery is at about 30 cycles)Default BIOS settings ("battery optimised" and "balanced" when on battery)Power plan: Balanced (there are no any other plans anyway) My usage is quite minimal: Microsoft Office, Firefox, Slack, with Google Drive and OneDrive running. For the first 1.5 months of using it, I was getting more than 10 hours of work time from the battery - I was never able to test that 15.5 hours promise, but after 10 hours of active use (i.e. minus sleep time) I still had had 25-30%. After installing the BIOS 1.34 update via Lenovo Vantage, my battery time was cut at least in half. The symptoms were:- the CPU was running at the maximum frequency regardless of the power mode I selected- the CPU temperature was around 50C (120F) or higher all the time, even on battery, while previously it had used to be at 36-38C (below 100F)- the promised work time from the battery even in the Battery saver mode was around 6.5 - 7 hours- EDIT: the strange thing is that everywhere - in the BIOS settings, in the OS - my CPU is shown as Core i5-8250U @ 1.60GHz, 1800 MHz. The former frequency is right, the latter is wrong - it's ... Read more

I have been going crazy as I am sure others have been trying to get my computer patched.  I ran Powershell commnds to see if I am ok.  I found out it is incomplete without a patch from Lenovo.  It would be a mistake to not issue a patch as this would seem to be a betrayal of trust for those of us who bought Lenovo products. Please issue. Here is an explanation. The image means that your system received patches for the Meltdown bug, but has received incomplete patches for the Spectre bug.This was to be expected, as Google said yesterday that Spectre is harder to exploit, but also harder to patch.What the red text means is that you need additional chipset firmware updates. Microsoft and Google say that OEMs will need to provide users with these additional firmware updates to complete the Windows OS-level Spectre patches. Depending on your computer's age, some OEM might not make these firmware updates available, meaning you'll be stuck with an incomplete Spectre patch.If your laptop/desktop/server vendor has provided extra chipset firmware updates, you can get them from their official sites, install them, and complete the patch.

Lenovo Support offers two ways to update the BIOS on my X220 laptop: within Windows, or booting to CD/DVD/USB.  When I try the first, I get a Page Fault in Nonpaged Area BSOD.  What failed: WinFlash64.sys.  I tried a couple of the eight or nine suggestions found online for fixing the Page Fault in Nonpaged Area issue, to no avail.  Thought to try method 2.  Lenovo's readme for this says: WHAT THIS PACKAGE DOES

This package provides the ISO image file of UEFI BIOS which is compatible with
CD/DVD/BD writing software to create the CD/DVD/BD for the UEFI BIOS update.
Hereafter the CD/DVD/BD for the UEFI BIOS update is called as "BIOS Update CD".

The BIOS Update CD can boot the computer disregarding the operating systems
and update the UEFI BIOS (including system program and Embedded Controller
program) stored in the ThinkPad computer to fix problems, add new functions,
or expand functions as noted below.

For that purpose, it is necessary to have the CD/DVD/BD writing software (with
CD/DVD/BD creation function from the ISO image file) prepared separately.
Well, where or what is "the CD/DVD/BD writing software"? I have several CD/DVD writing softwares, which don't write to USB. I downloaded a couple of programs to make bootable USBs, but either they require $29.95 to function or they don't seem to work with the Lenovo ISO. Any suggestions?

I got my X220 yesterday, so far I really like it, but it's very difficult to get access to the BIOS or the startup device select screen.  If I press the ThinkVantage button at the POST screen usually either nothing happens or the recovery partition boots.  Pressing F1 for BIOS or F12 for startup device seems to work if I get the timing just right, but I frequently have to try 10 times (rebooting the machine) before I can get in.  I've seen this problem on firmware 1.16 and 1.17.  What do I need to do here?  I've seen someone on another forum having the same issue, is there a fix?

A:X220 BIOS hard to access

I agree that there is opportunity to improve startup key recognition, but what I do I press the button repeatedly until the POST screen acknowledges it... e.g. twice a second or something like that.  It works for me, because pressing F1/F12 just a single time is definitely not enough.

I have a 10 year old Lenovo X220 originally came with Windows 7 Pro, last year I upgraded to Windows 10 Pro and it worked fine but was very slow. I recently upgraded RAM from 4 to 16 Gig and replaced the original HD with a Samsung SSD. The SSD migration had no problems and I'm enjoying a much faster boot up and improved performance. I'm still running the original BIOS version 1.11 and I'm interested in installing the latest BIOS 1.46 but the X220 BIOS Download page only shows OS Windows 8, 7, Vista and XP. It does NOT mention Windows 10. https://pcsupport.lenovo.com/us/en/downloads/DS018805 Do you think it's safe to install this BIOS version 1.46 if my X220 is running Windows 10? The reason I'd like to install the BIOS is because the X220 still won't recognize an external USB keyboard, either docked or undocked. The laptop keyboard works fine and  I've used the Windows Device Manager to delete the Standard PS/2 Keyboard from the Keyboard folder, and I've deleted and reinstalled all of the USB Hubs and Controllers in the Unversal Serial Bus controllers folder. Still won't recognize the external USB keyboard. Thanks, Joe

Hi guysHave an issue with an X220 where the system was ready to be sent to the user, I did system update the night before deploying which included a firmware update, next morning the wifi was disabled. (original bios 1.28 I think, new bios 1.4).The wifi card is no longer detected by the system at all, indicating the firmware has disabled the card. I managed to force it back to a previous BIOS revision but the issue persists, I then rolled to 1.4 official again and have tried the modded bios v1.4 (without wifi whitelist).I have tried the original card in a different unit and it works, and have tried the spare units wifi card (same model card) in this X220, also not detected. So it seems the BIOS is still blocking all similar Intel cards. Interestingly if I try a Broadcom card from a different model Lenovo, it is detected in the mini wifi slot.So this confirms the slot is operational.I cannot use it however since it is a full size card and does not fit in the mini wifi section in the x220.Last idea I had was to try all the cards in the 2nd (full length) slot but that will not pick up any Wifi cards at all. Anybody have an idea where to look to enable the Intel cards again? I have seen mention of a pin which is used for this but surely with the modded bios this should not be an issue? Note that with any of the intel cards inserted no devices are detected in Dev Man, and no option to switch them on via Fn+F5 (wifi option missing) Thanks for any suggestion...

A:X220 wont detect Intel mini wifi, detects full size Broadcom, BIOS 1.4 w/o whitelist

HiWhat's the wifi card model, its p/n, Lenovo FRU? If this card isn't approved to use in x220, do you get the lock screen with error 1802 message during the laptop booting with original BIOS? Regarding the patched BIOS any question should be addressed to its author, it's not a deal of this official forum.BIOS v.1.4 wasn't released ever. Intitial, factory released version 1.04 dated 2011 year is outdated. The recent version is 1.43. It's impossible to rollback this version to any previous version, 1.28 including.

Is there going to be a bios update with the intel microcode fixes for the Y50-70? Preferably one that doesn't make the laptop restart every 30 seconds like 3.03 does?(See https://forums.lenovo.com/t5/Lenovo-P-Y-and-Z-series/Y50-Bios-3-03-problem/td-p/2178818 about the restart thing)
