Yoga 11s Windows 8 to Windows 8.1 Upgrade - Power Management Compatibility Issue

I recently upgraded to Windows 8.1 on my Yoga 8.1 device. I followed the application removal instructions before upgrading, then reinstalled the correct drivers for 8.1. Everything works well except for the fact that I get a Windows warning that there is a Power Management Compatibility Issue with the Lenovo ACPI-Compliant Virtual Power Controller. Any idea how to fix this? All hardware in the Device Manager are working properly.
Thanks in advance for your help. I have BIOS 7xxx.
Regards,
Nate

I have this exact same issue, but with the 8.x BIOS.
My 11S also has issues going to sleep automatically when plugged in or on battery power, as well as staying asleep more than one second when on battery power, regardless of whether I initiate sleep manually via the menu or by closing the lid/pressing power button. I figured they could be related to this, but I'm pretty sure I had the same issues before the Windows 8.1 upgrade.

IOS7 upgrade Zagg keyboard compatibility issues

I recently upgarded my iPad 2 to IOS 7 and my Zagg keyboard that I have always used with the iPad stopped functioning. Im showing that its connected to bluetooth but I get no functionality. Is there a fix for this that anyone knows of? Thanks.

Have you tried to go into the settings and 'reset all settings'? That's helped with some.
Mine is working just fine, which I know is a cold comfort. I have an older one, before they came out with the lit keys, so that could be part of it. I also have an iPad 2, so if your iPad is a different one that may also play into things.

Lenova ideapad yoga 11s

i probably wont be able to explain this properly but i will try my best else i will be going to contact lenova via hte phone.
For some reason i cannot launch anything on my lenova ideapad yoga 11 s.
for instance i click on the internet explorer icon in my little panel or the camera or the calendar or the photo's icon and they do not actually open, what happens is that they appear in the bottom task bar as if they are open but they arent opened i cannot see or access them. To open internet explorer i have to go to the search field on the computer and click on it here once it appears and then it opens.
does anyone know what the problem is with the computer and why it has suddenly started doing this.
I am not sure where to post this query on the lenova forum so if its the wrong section could you let me know and i will re-post in the correct forum.
Thanks in advance.
Moderator note: moved it for you.

Just for your information...I recently returned the yoga 2 pro to Best Buy and bought a yoga 11s instead. I have it upgraded to windows 8.1 without having any problem. All you have to do is to wait until the system automatically download and install the windows updates. And after rebooting the computer, go to Windows Store, the free upgrade to windows 8.1 will be available for you to download. While waiting for windows 8.1 to be downloaded and installed you can just go to Lenovo support website to find and download all the updated drivers for yoga 11s, which are compatible with windows 8.1. Then when the system automatically finishes the upgrade to windows 8.1, just simply updated the drivers one by one. So yeah, in my case, I did not have any problem or error when upgrading to windows 8.1
Hope this helps.

Just bought the Lenova IdeaPad yoga 11s Some tips, please .....

Okay, after a lot of faffing about, I finally decided on the 11s (i3 processor, 128GB hard drive, 4GB RAM, Windows 8). I wanted something that was fairly cheap (less than £500) portable, much lighter than my current laptop and good enough for basic use. This fits the bill. It should be with me tomorrow morning.
I have two main jobs on my list when I get it before starting to use it for what I bought it for. 1) Update to Windows 8.1 and 2) Remove all bloatware.
1) From experience, is the upgrade from Windows 8 to 8.1 going to cause me grief? What steps should I take to make this as painless a process as possible, please? What should I look out for?
2) What bloatware can I happily remove? I understand Lenova ae one of the worst companies for shipping their products with bloatware but I really don't want anything on it that doesn't need to be on it.
Any other top tips from 11S owners?
Thanks for your help.

Yoga 11s touchpad cursor jumps after finger release

Hi,
I have a problem with my yoga 11s touchpad on windows 8.1. Everytime I use the touchpad to point at something and then release the finger, the cursor jumps away. It does not jump far but it is enough to make me have to point again. I have the newest touchpad driver from the lenovo site installed. I tried all settings of this driver but it did not help.
Does anyone have the same problem or a solution for this problem?
Thanks and kindly
Peter

Dear Customer

How to handle power managment features of Windows Vista

Hi guys
I searched a little bit in the Toshiba Technical Knowledge Base and found very interesting article about the power management features of Windows Vista.
*[How to handle power management features of Windows Vista|http://aps2.toshiba-tro.de/kb0/HTD84026Q0000R01.htm]*
The point is that you will not find a same Toshiba Power Saver tool on Vista like on the Windows XP notebooks and the power saver settings are a little bit hidden in the Vista Power Saver settings.
But you can also control the certain options like Cooling Method or Power Saving Mode.
I think this document could be interesting for some here in the forum!
Greetings to all!

Hi Jayjay
Thanks for posting this here in the forum.
Several days ago I searched for such further power option in Vista.
This document was really, really helpful for me.
Thanks again

Installing Acrobat Standard 6.0 under Windows 8 & Microsoft Office 2013 - compatability issues

In older Windows/Office versions, a PDF Printer was integrated into software, such as Word. this would allow you to print directly into Acrobat in PDF format.
Under Windows 8 Office 2013 there seem to be compatability issues and I can not longer print to Acrobat.
Are there any patches or solutions out there ??

i'm a fan of doPDF: www.dopdf.com
which allows any app with print capabilities to print a pdf document.

Windows Power Management settings don't work with ITunes

Purchased a refurbished Dell Optiplex system a few weeks ago with a 3.2 Ghz Pentium processor, 1 gigabyte of RAM, and 160 GB of hard drive - so a nice, new, fast system running Windows XP.
I set my Power Management settings to go to screen saver after 20 minutes, and power down after 45 minutes. It worked just fine for a month, and the day I downloaded Itunes onto this computer, those settings do not work.
I have reset them.
I have changed them (to as little as one minute).
I have changed them back to the original settings.
I have rebooted my computer.
I have run 2 different spyware programs (Spybot and Adaware) as well as run an anti-virus scan (TrendMicro Housecall).
Nothing has changed, and my only conclusion is that Itunes is somehow interfering with the power settings for my computer and monitor. This is rather frustrating, as I'd like my computer to shut off on its own if someone walks away (I can't trust my kids to log off on their own).
Any ideas on what the problem might be?

Hi, I just bought my iPhone a couple of days ago and am having the same problems.
I have a Macbook at home, but need to be able to sync with my work computer for contacts and calendar. At work I'm running on Windows XP Pro SP 2 and MS Outlook 2003 SP 3. I've made sure to update all MS software. I'm running on iPhone 1.1.3 and iTunes 7.6.
My contacts sync fine, but, so far, no luck with my calendar. I've gone through the trouble of completely deleting everything off my calendar and am trying "test" appointments to no avail. What's really frustrating is that I've logged out of my ID on this computer and logged in using a test ID. I can successfully sync a test appointment following those steps.
Tech support tells me that since I'm successful under those conditions, it must be a corrupt entry on my main calendar. But, as I've mentioned, I deleted everything I can find off my main calendar and am still not able to get it to sync successfully.
This is quite frustrating.

Yoga 11S upgrade to Windows 8.1 issue

My YOGA 11 S came with Windows 8.0. I upgraded to Windows 8.0 Pro W - Media Center without an issue a few weeks ago. Today I have twice attempted to install the WIN 8.1 Upgrade from the Store. Both attempts failed and rolled it back to WIN 8 pro. It's a stock machine, no mods at all. Please let me know if any others are experiencing issues.
Both times the error info were reportedly sent to MS.
Thank You

Found this link for a conexant driver for another Lenovo device:
http://support.lenovo.com/en_US/downloads/detail.page?DocID=DS037884
Downloaded and installed it on my yoga 11s, now with 8.1 pro. After download and install, a restart was required. After that, the conexant HD audio and Dolby Digital Plus Home theater returned to my list of programs. Windows Media player worked with video and audio. Flash player worked using WatchESPN.com. Seems to have fixed one of my 2 errors.

Cannot install Windows 8.1 Update on Lenovo Yoga 11s

Hi guys,
Hope someone will be able to help me out from this never ending issue.
I have been trying to update my Yoga 11s to Windows 8.1 for the last 2 weeks, but it just doesn't work. It kees failing when it gets to "Applying Settings" and then reboots twice and eventually rolls back to the Windows 8 installed. I have tried everything I've read on the internet from disabling my BT to installing all the latest drivers to even installing from a clean boot of Windows 8, but NOTHING works.
Has anyone successfully made this upgrade? Any assisstance will be highly appreciated.
BTW my laptop is installed with Windows 8 Single Language and running BIOS version 77CN20WW (v1.06)
Thanks

Thank you for your input. I must say that I did have 8.1 installed and used it for about a month with no issues. Then recently when I was installing an update for graphics I got the black screen as described. I have since then not been able to install 8.1. I will continue to look for a solution. Thanks for your reply

Trying to create dual boot with Windows 7 on Yoga 11s

I was trying to install Windows 2008 server (I said Windows 7 in the title because it's essentially the same) on a Yoga 11s in dual boot configuration with the factory-installed Windows 8 upgraded to 8.1, and as expected it's a pain in the butt.
I ran into the catch-22 that you can only boot from a USB external optical drive in legacy mode, and then Windows refuses to install on a GPT-type partition. Dead end there.
As plan B, I tried installing from my MSDN DVD from within Windows 8.1. It chugged along for a while, but then hung after the second restart. It reached a state where the machine is dual boot, and goes into Windows 8.1 OK, but 2008 server hangs on startup even in safe mode. Probably it's a driver problem. I downloaded all Windows 7 drivers for the Yoga 11s from the Lenovo website, and they would work fine for 2008 server if there was a way to put them in place.
I have been through the process twice before on previous machines. After getting the server OS to install, none of the devices work well or at all, but I could patiently install the drivers using device manager. This is the first time where I can't get the server OS to install to a bootable condition. Is it hopless, or might there be documentation somewhere about how I could manually place drivers in the right folders to enable the OS to start?
Plan C might be to follow Lenovo's instructions to create a UEFI bootable USB flash drive and try to install from that. Would that work better than installing from within Windows 8.1, or just reach the same roadblock?

Reformat that new drive with SL DVD.
Go into SL DVD again, go to Utility Menu and choose DU.
Then try repairing the drive or better yet, just erase the drive (not the volume) and try again.
There are enough changes between Tiger partition scheme and SL that you would want to. RAID arrays built with Leopard will not allow installing SL, they have to be recreated (and can then have Leopard and SL).

Yoga 11s webcam Windows 8.1 Driver

When we updated to windows 8.1 we lost use of the webcam on this yoga 11s. I was advised to uninstall and reinstall it. I have uninstalled it but now unable to install another webcam. My daughter lives 1100 miles away and can no longer skype. Help please
Moderator Note; subject edited.

Hi,
I have a similar problem. I bought my Yoga 11S in july 2013. It ran windows 8.0, unfortunately I did not check the camera was working at this time. I updated windows to 8.1 some time after (I will not speak about problems with dolby, etc...) and just check recently if the webcam was working (skype usage). The webcam is not in the device management, I tried to installed the driver given by Lenovo for windows 8.1 64 bits but the result is "No appropriate Driver to be installed".
Unfortunately I am not able to say if it was working in Windows 8.0
I contacted the French Lenovo Support who asks me to come back to initial configuration, they refuse to do anything else before that to know if it is a hardware or software problem.
I understand but I I am not willing to come back in 8.0 and I am pretty sure there is another option.
Any ideas or suggestions ?
Thanks
Laurent

hi 2jj3,
According to this website, the ACPI\CIND0C60 is the Intel(R) Dynamic Platform and Thermal Framework Processor Participant Driver (DPTF). Have you tried running the Intel DPTF Driver for 64-bit Windows in Win7 compatibiity mode?
The root\LenovoVhid is most likely the Lenovo Energy Management as discussed in this thread.(this is the software that controls the Function keys). You may try this driver but if it doesn't work, you may need to leave this out for now.

Yoga 11S on Windows 7

Hello,
i tried to install Windows 7 64bit Enterprise on a Yoga IdeaPad 11S and downloaded all available driver setups for Windows 7 64bit from the lenovo website. I was unable to install the following driver packages:
- Conexant Audio Driver
- Camera Driver (Bison, Chicony)
- Intel Chipset Driver
- Intel USB 3.0 Driver
- Intel Video Driver
- Touchpad Driver (Elan, Synaptics)
At the moment we need to use Windows 7 because an important software isn't compatible to Windows 8. Is there anyway to get the Touchdisplay working?
Kind regards,
Michael

Hi Jonas,
i need to use High Speed Data Converter Pro from Texas Instruments. It is a tool for evaluation boards from TI and the problem is the usb connection on Windows 8. You can install the software on Windows 8 but you can not connect to the evaluation boards via USB. I asked for this problem in a TI forum as well, but the developers have no idea why the software isn't working on WIndows 8.
I got that idea with a virtual machine too, so i installed Windows 8 again on the Yoga 11S and tried to run Virtual Box, but now i have the problem to install a Windows 7 64bit version on the virtual machine. Up to now i'm only allowed to install 32bit OS although i enabled the hardware virtualization in the BIOS.
With Hyper-V i made it to install Windows 7 64bit on Windows 8 but wasn't able to run USB on that Hyper-V. First attempts were via remote desktop connection but didn't work so far.

Lenovo Yoga 11s SSD and RAM Upgrade - Great Results

Picked up a Lenovo Yoga 11s from Best Buy. I chose Best Buy for price, color, and processor. They had a slightly better deal than Lenovo.com. The clementine color looks great. Quality is great. I'm very happy with the purchase. It has the i5 processor, 4GB RAM, 128GB SSD.
I upgraded the SSD and RAM and found the upgrade relatively easy. Here is a basic step by step and results. (note the parts I chose increased the cost by close to $400. I chose these parts based on quality, performance, and power usage. There are cheaper alternatives, but I wanted an upgrade and money was not my concern.)
Upgraded Parts
RAM - Patriot Memory 8GB PC3-12800 1600MHZ CL11 1.35V - Purchased at Newegg, but could have saved a couple dollars on Amazon.
I chose this part based on previous experience with Patriot and the low voltage RAM. A lot of the RAM is higher voltage and I wanted to make sure I reduced heat and power usage. When you look for 1.35V RAM, there are not a lot of options...
MSata SSD Drive - Intel SSD 525 Series 240GB Drive
Intel SSD Page
I purchased through Newegg
I chose the Intel drive based on previous experience with Intel. They cost more, but I've found their performance to be good and reliability good. There is also a good review on this drive on Tomshardware Tomshardware Intel 525 Review. Toms review shows top performing drive and low power. I also looked at many other manufacturers and Intel had the lower power consumption. This means less heat and longer battery life.
Cloning Software
Intel provides a free cloning software from Acronis
My Digital SSD MSata external case
I purchased through Newegg.
Nice quality device. I used this to help in cloning the OEM SSD to the new Intel drive.
T5 Torx Screw Driver
I purchased this from Home Depot T5 Torx Home Depot
I read all the reviews, posts and issues around cloning the Win8 SSD drives. Many people have/had issues. I was prepared for problems. Another reason I chose Intel, as they have migration software that I felt would be top notch.
You need to have the Hardware Manual handy. I read how to remove keyboard and top cover. This is required to upgrade RAM and SSD. It was very easy. Take your time. Note, this is very different than the Yoga 13 youtube video for part removal. I think it's easier. Here is the link to download manual Yoga 11s Hardware Manual.
How to clone your SSD
I expect if you're doing this project you can learn how to use the Intel software for cloning. Read the web, watch their youtube video. Read the manual...
Remove your factory SSD and insert new Intel SSD (note, you must insert Intel drive in notebook for cloning. Do not try and clone on the USB external drive. Intel software will not detect drive properly). Create a bootable version of the Intel software on a USB drive. Install your factory OEM SSD in the external MSata SSD drive. Go to BIOS and set boot to support legacy, no fast boot, boot to USB.
Boot to the Intel Acronis app on the USB drive. Then connect your OEM SSD via second USB port.
Then follow the wizard on Intel's software. Cloning process took less than 5 minutes.
Unplug your USB devices, go to BIOS and set all all your boot settings back to factory UEFI, fast boot etc.
The PC booted to windows second try. The first time it said it has issues and went through a process to repair. It then said it failed. I rebooted again and it went straight to windows. Did all my windows updates and everything is fine.
Performance
Windows Performance Improvement
Memory - Factory score was 5.9 - Patriot Memory is 8.2 *** Nice Improvement
Hard Drive - Factory score was 6.2 - Intel 525 Drive is 8.2 *** Nice Improvement
This pc is crazy fast booting and shutting down. It boots in 7 seconds. Not sure it's really faster than OEM, but I've never seen a pc boot this fast.
Over all performance is fast. I installed Office 2010 pro from a USB drive in under 5 minutes. Web browsing is crazy fast. I'm super impressed with the speed of this pc. Much faster than I expected.
Size, Shape, Weight, color is great. Performance is great. Happy with upgrades and quality of parts. May be my best notebook purchase to date. I don't have any battery life numbers to report yet. Everything is new and I haven't really spent much time off the charger.
Issues I've experienced during this upgrade of parts
I first tried to clone the SSD drive by putting the Intel drive in the USB enclosure first. The intel software would not work as the PC detects the external SSD drive as a SCSI drive and Intel cloning software could not identify the drive as an Intel Sata drive. I called Intel and they had no advice or help. I also tried a few other cloning softwares that ultimately did not work. As a last resort I switched the drives and everything worked great. Lesson learned, swap the drives first and use Intel software to clone.
Factory restore - doesn't work. Not sure why the factory restore is not working on my new Intel drive. Windows works great! All the partitions are there. I suspect I messed up the OEM restore portion of the drive. At one point I thought I had booted to the Intel drive, and tried the restore (I had about 7 failed cloning tries before the final one worked as I outlined above). It went through the restore process and then failed. However, what I later found was that I had actually booted to the OEM drive in the external USB case and I may have corrupted the restore functionality.
I contacted Lenovo Support and explained I could not restore using the 1 key restore. They walked me through some basic troubleshooting and then opted to mail me factory restore disk. I have the disk and will keep them available for when/if I ever need to restore.
Solved!
Go to Solution.

I upgraded from the Yoga 13 to the 11S and am happy to report that the machines are so identical that apparently you can just yank the SSD from one and drop it in the other. I had upgraded my 13" to 240gB SSD + 8gB RAM and simply plopped the two components into the 11S and after about 30 seconds of Windows alerting me that it was 'setting up devices' the machine booted normally and has been working perfectly since!
