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.)

My S1 Yoga, 20CD-00B1US, is stuck with the screen off and the power LED stuck on. When I try to push or hold the power button it beeps two short beeps and the LED stays solid. I was running the Lenovo Bios Update Software directly from their site. The power cord was plugged in and no other programs were running (aside from background programs). Now it is just stuck like this. Any thoughts or help would be great. I can't even get it to force shut off. Thank you in advance!

My Yoga S1 has contradictory, intermittent power issues that I'm trying to chase down. Culprits are bad power bric/cord/plug or power socket on mother board or power board that feeds into power button/led on. One day it blacked out and wouldn't restart to hard drive or windows stage. I did get an error code which I can't remember 5100 or 5500 poss?, that seemed to indicate the power board or ribbons to that needed replacement or re-attachment. So fiddled with it and it did fire up in windows all ok. Then ran out of power and died again. power button wouldn't light up. plugging in power unit did light up led as getting charge. Left it overnight and then it miraculously charged up. pushed power button light up twice then nothing. took out power board/detached ribbon, then it fired up to windows, fixed some hd errors and has been restarting without problems. Except now there is no plug showing on battery icon when plugged in. So not recharging but I'm sure the battery is good. And logically, the power brick and plug must be feeding electricity into laptop to get it to recharge enough to start up. So power socket and plug may be suspect with intermittent contact problems. Or the power board somehow is involved in this? I've ordered a new powerboard as easy screw in and cheap. My question about powerboard is does this control ability of plug to charge battery? power brick with new plug is next order from ebay. but the power socket, which see...

I purchased a refurbished ThinkPad S1 Yoga (20CD-00BYUS) a month ago, from eBay (US-based shop) with guarantee active up to April 2015. Everything was fine and satisfying until yesterday. After a normal shutdown the night before, it won't power on anymore. The battery was still about 50% on the last shut down. If I press the power button (normal press or even more than 5 sec press), the "red i dot" will light for about 4 sec and then off. No noise, no other sound. I tried to push the emergergency reset button as instructed on the manual, but it didn't work.I tried also making bootable USB, but also didn't work.Anyone have idea what I have to do before the ultimate option = send it to the customer service for repair? I read some similar problem in this forum and it seems useful to check the MB cable. Is it true?Will it affect the guarantee? Thank you for your help.

A:ThinkPad S1 Yoga won't power on

no. i was the one that provided the MB cable solution. From your description, it does not fit the problem. If the MB cable is disconnected, the led should not even lightup when you press the power button. the laptop should be totally unreponsive, except when the power adapter is unplugged then plugged back in.

I have a TP S1 Yoga (Model 20CDCTo1WW) running Windows 8.1 Pro 64bit. I utilize it mostly at work and have it hooked up to a Thinkpad Onlink Pro Dock.  I use the dock to run two external monitors, for connecting to our network (through an ethernet cable) and utilize the USB ports on the front/back to hook up a wireless keyboard/mouse, for powering my phone and for thumbdrives.  I had the problem of the Onelink having port "flapping" issues (network would disconnect and connect at random times) as discussed elsewhere in these forums.  The solution that I found was to update the bios.
 
I proceeded to attempt to update the bios (which I had not done since I purchased it in January 2014).  The current bios version is: GQET32WW (1.12), 1/22/2014.  I downloaded the TP Yoga bios update utility for Windows 8.1 (64-bit), Version 1.18.  I read the README and then ran the utility.  It installed the utility software to a location on the local drive ("c:" ) and then proceeded.  I went through the setup screens, selecting the "Update ThinkPad BIOS" clicking through a few more text boxes (with the warning about not powering off, keeping it plugged in, etc) until it asked to reboot. I clicked OK to reboot, which it did.  This is the next thinkg I seen on the screen:

Hi! We have a number of ThinkPad Yoga 11e, most of them are about 1.5 years old and we're currently updating their Windows 10 image and BIOS. Imaging process completes fine, but updating the BIOS has caused us a lot of issues. When updating BIOS from within Windows with the latest BIOS Update Utility (1.26) from Lenovo's website the laptops crash with a blue screen of death (BSOD). We then tried all previous BIOS versions (from 1.10 and up), but they all crashed too. The current BIOS version on the laptops is 1.10, but even that failed. We initially ran the installer from our network drive with the installer file renamed for easier identification. We have since tried renaming the installer file back to the original name and running it locally. Have also tried running it only with wireless enabled, running only with Ethernet enabled. At one point we thought there might have been another installation process running in the background (drivers, Windows Update), so made sure that had all completed. The BIOS upgrade still crashed the laptop. We have been unable to pinpoint any of the above scenarios to be the culprit, as now some of them work randomly. Two machines side by side, one will work and the other one will fail. We're pulling our hair out with this one. Has anyone else had this experience and have you found what steps need to be taken to successfully complete the BIOS upgrade every time?

Hi and thanks for reading.After running updates through Lenovo Companion, I tried to run a game, and noticed that my performance was terrible. It was than that I noticed that my fans weren't working anymore, and the GPU was throtteling.I've tried a lot of different things. The fans just never spin up, not even on cold boot like they used to.I've looked around the forums for solutions (this was similar, amongst others), and tried running Lenovo Fan Test, which just gives me "Fan Unavailable". Other monitoring applications tell me there simply is no fan available, or the thing is running at 0 rpm, which is accurate.I read that fan control is part of the BIOS, so I checked, and I have the lastest version installed (1.14/1.24 as mentioned).The people from the Thinkpad yoga 12 thread suggested downgrading the bios. I tried different version but that just gives me the ol' "Secure Flash Authentication Failed" message. I have found the knowledge base articles telling me to turn off "Secure RollBack Prevention" in the BIOS. I went and had a look, and it was already disabled. I toggled it a couple of times, tried setup defaults, and "Secure Rollback Prevention" Enabled and Disabled to make sure, but everything I tried simply gave the same result: When I try to do a rollback, secure flash authentication fails. Period.The device doesn't have a CD drive, and I've tried running the flash tool from the ISO on a USB stick, which did run, but told me the firmware wasn't suitable for my device... Read more

Hi guys, I have no idea what's happening with my Lenovo Thinkpad Yoga S1 (it's about 3.5 years old, its warranty just expired). Every time I reboot, I get this weird message saying "Configuration changed, please reboot the machine...". I then proceed to reboot the machine and everything works but the bios options are always resetted! This makes the laptop extremely unusable for me as I always swap the fn/ctrl keys so that I don't have to learn a new keyboard every time I switch computers. If I go back and change the option, it works fine, but the next reboot it does the same message again and I have to reconfigure the bios at EVERY boot. I'm lucky this option is the only one I changed, otherwise someone that would have changed the boot order/graphics settings/passwords etc. would be in a much worst situation than me...At first this seemed like a typical bios battery being out of juice so that the config can't stay saved, but I've now changed the bios battery twice with new ones and this doesn't change anything... It's been working perfectly for 3 years but now it just suddenly stopped working for that reason (by not working I mean the bios that keeps resetting itself, I can still boot to my main OS just fine after).If anybody has any suggestion that would be greatly appreciated.

Hi all, I've been reading tonnes of threads here trying to solve my problems (which seem to keep getting worse) to no avail. I'm reaching out to anyone that can suggest some help before I end up bricking my yoga by accident or running it over on purpose.

Said clean install went flawlessly with Windows 10 installing the first time with no issues or errors. Since I had performed a clean install, all my previous apps, including the stock Lenovo apps, had been deleted. I had anticipated this and only really desired to reinstall the app that automatically adjusts the screen orientation when folding the cover back. So in an effort to find this app and any Windows 10 related updates that may be available I went to support.lenovo.com and used the handy Lenovo Bridge app to automatically detect my hardware and suggest relevant updates. While combing through the suggested software I noticed a BIOS update that noted added support for Windows 10.

I follow instructions to plug-in and close all programs.
The installing bars will not complete past 91%. There is a prompt that asks to pick Thinkpad or Model Number. When I click Thinkpad and NEXT the computer SHUTS DOWN immediately (right after warning not to shut down or damage may occur). The computer screen goes black and 3 ominous beeps repeated 3 or 4 times sound. When I restart my computer nothing has updated.
 
I am unable to complete the Critical Update after trying 4 or 5 times. (Tried downloading and deferring install and the same thing occurred.)
 
(In tandem, I'm getting numerous STOPCODE errors from Microsoft after updating with the Fall Creators update. Not sure if it's related. I've had a variety of problems since the Fall Creators update and was hoping the BIOS update might clear things up.)

This sounds a lot like a prior thread about porblems with BIOS 1.08, but that thread ended up marked as solved, while for me the issue returned on the latest BIOS update to 1.12. My CPU temp got up to 92C without the fan coming on. Conclusion: there still seems to be some kind of condition where the BIOS completely disables all cooling. I think it's the same problem as that earlier thread, and it's clearly not solved. Thankfully it IS possible to get out of this state by rolling back the BIOS version to the one that worked, instructions are posted here and three posts below that for further clarification.  Symptoms: you start noticing that the TPY gets oddly hot during normal use, or it experiences a forced shutdown due to overheating. It's also completely quiet. But: the fan itself is operational because you hear it briefly spin up during cold boot.  Given that LoneSentry mentioned that the problematic BIOS 1.08 did work on second install, there seems to be some 'random' glitch in the update process or in the BIOS. Meanwhile I'm pretty unhappy that I'm having to do continued truobleshooting on this machine.   Edit: going to the BIOS update page I saw that a newer BIOS was available (1.13), which you can install without having to disable Secure Rollback. Lo and behold. the fan is working again. The fan started blowing full speed right at the start of the EC flashing procedure. This is NO... Read more

Yep. At revision 1.13 and this is still going on. I have to roll-back BIOS revisions and then roll-forward to get the fan to work again. I've nearly burned myself in tablet mode quite a few times now. I just updated to 1.14 so we'll see how that goes.

There are reports of extreme throttling on X1 Carbon Gen6 (reviews on Lenovo reviews US page, or reddit). It seems X1C6 is limited to 23W/29W TDP, while X1 Yoga Gen 3 is limited to 44W TDP for short and long term bursts.  It makes little sense as physically X1C6 cooler looks bigger thus thould be able to handle longer/harder loads. Can we hope that it will be fixed in the nearest future? Or is there an actual reason for lowering X1C6 TDP, so people who expect 8650U to run at 44W should just look into buying X1Y3?

(sorry my english)  As other users solved this problem with - it did not help using more powerful adapter with 90W 4.5A or upgrade BIOS. Power Saver off, no other power saver activated. Many times HW tests from Windows Troubleshooting and Lenovo Vantage - everything OK.  I attached here HWiNFO specification. - Lenovo Thinkpad Yoga 460 (Windows 1709, all current drivers updated - no change with update 1803 - same situation)  The power adapter (and also i use many others - no change) will immediately reduce the processor frequency to a constant of 0.39GHz and using the bounce between 0 - 15% .Reinstall Windows, HW test and drivers etc. everything is OK.  Even no help from Settings - Windows - Options of Power - set min. usage processor 100% - no affects. The problem persists. ..omg... , whats that? Common opening of Explorer, Word, copying etc., and other elementary activities are now a matter of minutes - big loss of performance. Thank for your help

Everything was going fine until the day I updated my 20FY to the latest BIOS version (R05ET75W); now as soon as it goes to sleep mode, the olnly way to wake it up is rebooting ang losing all the not saved work.Everytime it happens I regret the day I sold my Dell Vostro to buy this machine.

I have a fleet of around 40 Thinkpad Yoga 260s (20FD-0004US) running Win 7 currently on BIOS package 1.50 that are unable to update the BIOS to any later version. Here's what happens: 1. Download any version 1.51 or higher BIOS2. Run BIOS udate utility.3. Yoga automatically goes to restart, but instead of restarting, it will shut down with blinking green power light. 1 blink every three seconds. Machine becomes unresponsive; will not wake up.4. Force shut down by holding power.5. Start up and receive "Secure Flash Authentication failed!"6. At this point, the system is very unresponsive; cannot even power down by holding power button. Must open bottom of Yoga 260 and pull the battery. This is happenning with our entire fleet of Yoga 260s. Troubleshooting:-Disabled Secure Rollback Protection in BIOS-Tried several different BIOS versions from https://pcsupport.lenovo.com/us/en/products/LAPTOPS-AND-NETBOOKS/THINKPAD-YOGA-SERIES-LAPTOPS/THINKP... No luck with any of them so far.

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.
