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!

I have an old Lenovo Thinkpad Yoga type 20CD. Recently I lost the system after a Windows 10 update.It took me a month to get the Lenovo recovery CD because the BIOS of this machine is locked.I found myself under Windows 8.1.The PC ran for 2 days but failed as the SSD was in poor condition.So I bought a SSD in the trade identical to that of the machine with a similar reference Lenovo. After formatting, the repair CDs refuse to install the system.I think they are good but they are intended for recovery only and do not recreate the proper disk structure.Who would have the solution to recreate this structure? I almost succeeded (UFI partition in fat 32, partition MSR, partition of data in NTFS but I can not create the locked system partition (1000 Mb) I could have done it using the commands in CMD but they no longer work under Windows 10 (for example SET DISK or other instructions that worked previously are no longer recognized.How to do it?Help!

A:Thinkpad S1 Yoga 20CD will not power on

I'm facing the same issue. Suddenly it won't power on. Only LED indicator blinks when plugging in the power supply; and the LED turns on for a few seconds without plugging in the power supply. Beside that nothing happens. Any clue how to solve this? I've checked the connectors but they look ok. I've also tried resetting via "reset button" on the backside. further I've tried several sequences pushing the power button and holding it for 30 - 60 seconds.So far nothing helped. Any clue?

After running updates the computer will no longer POST.Turning on power only boot cycles (turns on for 3 seconds, turns off, turns on etc.), screen is black, no POST.Possibly a BIOS update fail?

A:After update ThinkPad Yoga, 20CD cannot POST!

I wish they would stop pushing BIOS updates other than at the request and guidance of support, they seem to fail too often and brick far too many systems.       You can usually perform a Boot Block Recovery on modern motherboards, but I do not think Lenovo has implemented that technology on their laptops for security reasons, but you might still check with Lenovo Support to see if they have any options short of replacing the system board.  BTW:   Does your system have the emergency reset hole on the back side of the case, and if so have you tried unplugging it from the power supply, and then pressing it for about 10 seconds or so?  (see item #1 on page 46 of the Hardware Maintenance Manual) Hardware Maintenance Manualhttps://download.lenovo.com/ibmdl/pub/pc/pccbbs/mobiles_pdf/s1_yoga_hmm_en_sp40a26742_01.pdf

Long story short, i erased everything and performed a clean install of Windows 10 64bit and the computer stopped shutting down or go into sleep mode. I had Windows 8.1 64bit, i upgraded it to Windows 10 about a year ago, when it first came out. The upgrade went almost fine, some bit issue with the OS but nothing serious, so i went on till i decided, to correct those little issues, to perform a clean install.  So i downloaded the media creation tool, the version with the anniversary update, and erased everything, but keeping the recovery partition. After the install, i started having troubles with entering sleeping mode or shutting down the laptop.I installed the power management driver i found on the site (n1cku04w). With that I can shut down even if it strangely blinks a few times before shutting down. I can enter sleep mode and wake it up properly if I do it from the start menu, but if i close the laptop or try using the power button takes me to a state where OS is sleeping and HW is still awake, so i can't do anything apart from force it off. Strangely too, the driver on the site is overriden from another version i recieve from System Update app. But, with the version from System Update app, i can't even shut it down properly, the OS dies but the HW is still awake and fully functioning leading me to kill it pressing the Power Button. Anybody have faced the same issue?

Hello Everyone! My ThinkPad Yoga was my daily laptop for years until it stopped charging. I replaced the wall adapter in hopes that it would be a cheap, easy fix, but that didn't work any better than the original one. It won't turn on and the red charging LED (the dot on the i of the ThinkPad logo) doesn't light up anymore.

Hello to everyone,I'll need your help. I installed a new, fresh Win 8.1 operating system on my Yoga S1. I also mount a new Intel SSD in the place of the old HDD. So it's way faster now I need to have a HDD password, also a start-up password. So, i set the same password (I'm sure, double-triple check it) for supervisor, power-on and HDD password. I enabled the password on restart option.So here is the problem - when i power on the Yoga, it asks for the power-on pass. I enter it and it is corect. Then, it shows that it enters the HDD1 pass automatically and it is succesfull. The system boots and it's fine. But when i press Restart from Windows, it powers off, ask for power-on pass - correct, then it asks for HDD1 pass. It's the same and should be automatically filled, like in cold start. Ok, it enter it manually, but it is incorrect. I also tried with blank pass, but without succes. So, after three incorect passwods, it freezes. Then, I power off completelly, start again, enter the power-on pass and it's fine, it boots the OS. So, it's not working on restart, but cold starts are OK. As I said, I checked many thimes that the passwords are the same. Please advice guys.Thanks to everyone

Also tried a second power supply.4) Removed cover and used voltage meter to validate 20V at board soldier points for the power jack (so power reaching board)5) Checked all chips, hard drives, connectors that were readily visible to make sure they were tight. Nothing when plugging back in. Questions:1) Anyone know of any common remedies or things I can look for?2) Any general guidance on getting something like this fixed? (ie, send to Lenovo, find a big name store like Best Buy, other?) Thanks!

One of my end users has a ThinkPad Yoga 20CD-00BYUS. He's one of the few users in my organization with a Lenovo device. His hard drive failed. I've purchased a replacement, but don't have any setup/recovery media. Is there a way to obtain this? I can't seem to find a way to do so on the Lenovo site, at least not for a device out of warranty.

A:Yoga 20CD hard drive failure - recovery media

If the machine has been upgraded to windows 10, you can download (free) from Microsoft.  To obtain the media to recover your machine to its original configuration, you can call 1-800-426-7378 and tell them you need to purchase a recovery set for a machine out of warranty.
 
I will add that Microsoft does not make it easy to apply security and driver updates to a newly-recovered windows 7 system.  If you had win 7 and you ever want to upgrade, now is the time.

Hi there, hopefully someone can help me. Back when my laptop was still under warranty, I complained to Lenovo about the many scratches I was getting on my screen from using their pen. I don't press hard when I draw, and I even bought replacement nibs just in case there was something sharp on the one I was using. Alas, nothing helped. This didn't happen on the last tablet Thinkpad (X61) I had! At the time, I couldn't afford to send my laptop in to get it repaired. I was in the middle of a VERY busy college year. But now, the scratches are so numerous, it's really affecting my ability to work on it. Is there a way to just... replace the matte finish? Looks like it's like a screen protector to me. Is that something I can purchase on my own, or would I nee to take my laptop to a repair place to get it put on correctly? I tried to see if I could take the thing off myself, but I can't even get my fingernail under a corner. I HOPE it's a screen protector of sorts, because there's no way I can afford replacing the entire screen.

Hello all. My laptop used work perfectly until the day I decided to remove all the extra stuff by doing a clean install of Windows 10.  I predownloaded all the drivers I would need and then did the clean installation.  Now I have an issue with my wifi.  It randomly drops connection to wifi and is slow to start working again.  After coming out of sleep it does not automatically reconnect to the ap and I have to trigger it manually.  Separately (i think) when coming out of sleep, the login screen does not respond to the keyboard and I am forced to use the mousepad to click or a touchscreen swipe to get to the password field. What I'm seeking is an official list of drivers that are required for a clean windows 10 install on a thinkpad yoga series 20CD.  If order of installation is critical, please give this also.  I believe I downloaded everything available from the support page but just want to be sure.  Sometimes not all drivers are available when filtering by OS "Windows 10".   Thanks in advance. Laptop specs are:512gb ssdmemory card slot2.4/5 n/ac wireless 7260ac w/bluetooth

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! 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 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.

I have tried multiple time to install the Thinkpad BIOS UPdate - 7/8 [32,64]/8.1/10 [64].
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.)
 
Any advice?

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.

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

A:Thinkpad Yoga 12 BIOS update disables cooling fan

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.

Few months back I got a Lenovo ThinkPad P40, it has been working just fine untill the latest BIOS update from Lenovo Companion (R05ET72W 1.50).  Since I use it for work, it is connected to power all the time. I have disabled Sleep & hibernation when plugged-in. When I leave the workstation, I usually just lock the machine (Win + L), so that I can access the laptop from home.  After the latest BIOS update, when I get back to work in the morning, ThinkPad does not wake up no mater what button I press. Opening the lid, shows a black screen, does not respond to anything. The red light on the "ThinkPad" logo is lit.  All I can do is hold the power button for 5 sec and re-power. This is horrible, as it will sonner or later corrupt my Windows installation.  I've had to do this now 3 days in a row, after the BIOS update.  I've updated all drivers and ran Windows 10 update. The EventViewer shows only this:"The previous system shutdown at 5:56:01 AM on ?11/?5/?2017 was unexpected." But I ran the force shut-down at 8:30 AM...
