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.)

I recently bouht refirbished Yoga 500-15IBD, It has Intel HD 5500 and GeForce 940M. When I bought the laptop online I was under the impresion that the display is FHD. Unfortunatly the maximum resolution that I see in the Windwos 10 display settings is 1366x768. Is this a software issue or the display is not FHD? I am wondering if it is possible that seller changed the original FHD display with HD display. I can't find the full spec of the laptop. Machine Type Model: 80N600FWUK.

Hi, I've tried looking for tech specs (I know the hardware specs) for the monitor so I can work out what pen/stylus would be best for the touch screen. However, I can not find this particular product (spec specific) on the website.  If anyone could help me out that would be great, Ideally I'd like something with pressure levels as I do digitally draw from time to time, and would be helpful whilst writing. But would settle for something that isn't due to owning a GFX tablet anyway. Also, I'm unsure if this ideapad is referred to as a 15, 500 or 8 due to not know where this terminology is based from (model name, model series ect) seems unclear, perhaps I'm just looking into it too much and it is just a 500. Thanks to anyone that spends time reading, and thanks in advance for advice. ~Kris

I bought the yoga 500-15IBD(w/i5 5200U;GT 940m and 8G of RAM) in summer of 2015. At first the notebook is doing fine. But at mid-late 2016 the notebook start acting strange, the CPU start lock the frequency at 0.44 Ghz while charging. I find out that the BD prochot is the reason and I disable it with throttlestop. Then when I start gaming for few minutes the laptop just shut down, because of overheating. So I try playing game with BD prochot on and with battery. And the gameplay become very laggy. Not like low fps, but just very laggy. I monitored the CPU and the CPU just get throttled massively frequently and the frequency just go up and down. Which never happen before, the laptop used to be at least playable with consistent (low) fps.  What should I do. Is some component damaged? Should I clean the fan (I checked the fan and it seems fine to me)? Should I charge the thermal paste?  ps I try to stress test both CPU and GPU, it's fine when doing test alone. But when testing both CPU and GPU the temp of CPU just go sky high (~100 C) and the GPU seems to be cool in terms of temperature(75 C)and than the laptop shut down. Even when testing GPU only while CPU is idle both temp got ~75 C. When doing only CPU test CPU temp ~88 C max and GPU stay at ~55 C. It seems the GPU is transfering heats to the CPU.

I bought a new Yoga 500 15IBD 2 Months ago and since a view weeks the Laptop had several power breakdowns while in battery mode. All of a sudden the Laptop turns black, all lights and the hdd turns off and I have to connect the power cord to get it started again - although the Battery certainly isn't empty according to the OS-Battery indicators AND often having the Laptop fully charged less than half an hour ago. (The Yoga runs for at least 3 hours if the bug does not appear). Now this is no driver issue, I have the problem while running Windows 10, Linux Mint and Backbox Linux. I suppose it's either a battery issue or a faulty architectual design. Since  I see a lot of similar power-off related messages accross the spectrum of lenovo devices, could someone finally publically explain the source of the problem so there is a chance to get rid of it ... especially in future products?

Hi, I got a problem with my laptop. The fan is making loud noise everytime I open a new window, a new tab, any setting window and so. I believe it is supposed to make this kind of noise when I'm stressing it with more programs running, not by simply open the files explorer... Any idea on what to do? (model is Lenovo Yoga 500-15IBD)ThanksNstant

A:Lenovo Yoga 500-15IBD loud fan noise

Hi Nstant,  Most probably a program or App is running at the background cause fast spinning fan to cool down CPU temp.  To figure it out, right click in your taskbar and from the opened menu click on task manager.  -From top menu click on performance tab then click on resource monitor ==> from top menu click on CPU tab and look at to the Average CPU usage and see which App or Program is using a high percentage of your CPU capacity==> right click on it and end the process.  .Regards,  **If the issue has been resolved please, mark me as solution provided to help others find the solution easily and click the Kudos.**

Hi everybody, when I unplug the charger on my yoga 500 the screen starts to flicker like a rave party, I have searched like crazy all over and have found no solution to the problem. Things already tested:-Unplugging and plugging battery cable.-Disabling Windows error reporting service and Problem reports and solutions-Trying to update intel drivers from driver section and intel site.-Trying to update, and disable realtek hd audio driver. Things to take in account:-When connected to a second monitor, the new one won't flicker.-Laptop has warranty voided because of ssd install. (problem still occurs on bios with and withouth an HDD/SSD) so it shouldn't be considered a Windows 10 problem.-After SSD install, windows update doesn't allow me to update anything. I believe it thinks I'm booting from external hard drive. I cloned the original HDD into the SDD so that shouldn't be happening-Flickers increase with mouse, cursor and touch. Anybody has a fix for this? I read that a lot of people have this problem but I rarely see fixes.proof video https://www.dropbox.com/s/gttvhylvggtug7x/2017-05-26%2013.00.00.mov?dl=0

I need help recovering from my Yoga 2 Pro freezing during the reboot while updating my BIOS.   A few months ago I upgraded my original EVO 850 128GB SSD to a matching EVO 850 1TB SSD, with fresh install of Windows 10 Pro from a bootable ISO thumb drive and restored data from MS Office 365 OneDrive. Battery conservation mode stopped working after that, even with that feature set in a new copy of the Lenovo Settings tool.  I tried tackling that problem (and a few other glitchess) by downloading updates from the Lenovo Support site.  Drivers that were newer installed with no problems, skipping ones that were older than MS Windows Update versions.  But the BIOS update is now a real problem.  I confirmed I have a Yoga 2 Pro and it told me it is proceeding from version 31 to version 43.  I assume it completed the flash and was trying to reboot when it hung.  Of course I am out of warranty, and probably now can't get premium paid support considering I don't have the original 128GB SSD with recovery partitions. Can anyone help me?  It might be as simple as powering off and restarting into the BIOS to reset some defaults I had changed.  But I'd rather let it sit until I get a response here.  Thanks in advance for any help from someone that had this problem and got past it with a known solution.

I upgraded my yoga to Windows 10 soon after purchase a year and a half ago.  I have had few problems but one persists, intermitent problems charging with the AC adapter. There appear to be many Bios updates since the one that came with my yoga. I am running v1.03 and would like to update to version 96CN31WW(V1.17) but am justifiably concerned. - There is no means of backing up and restoring the current Bios so an update failure could be catastrophic.- The Bios readme file indicates it is for Windows 8 and 8.1.  I read a forum post that indicated that this shouldn't be a   problem on WIndows 10 and I agree but there is so little feedback in this forum or elsewhere about successful or   unsuccessful Bios updates on Yoga 2 13 so I am nervous about proceeding.- I don't know if this Bios update will solve my problem (no documentation from Lenovo about what any of the prior   Bios updates fixed) and there is always the possibility that this change could make my notebook more unstable. Again,   no means of going back.- For the reasons above, I always consider a Bios update a last resort. Anything else I can recover from and I am out of   warranty. I would appreciate any feedback on the stability and success of 96CN31WW(V1.17) updates and any information about what problems prior Bios updates for Yoga 2 13 addressed.

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 all, I've been reading tonnes of threads here trying to solve my problems (which seem to keep getting worse) to no avail.

I had some spare time at home and decided to download and install my free upgrade to Windows 10. I backed up all of my important documents etc to OneDrive as I intended on performing a clean install. 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.
