Lenovo Yoga 2 Pro Flex :: Screen Not Rotating On New Windows 8.1 Install

Dec 1, 2014

I got my new Yoga 2 Pro last week and the screen rotation worked properly. I decided to wipe the partitions and install my own version of Windows 8.1.

Since then the screen rotation doesn't work. The screen rotation button doesn't do anything and I don't have the 'Enable auto-rotate' checkbox in the resolution screen
In my device manager I have an error on 'HID Sensor collection' saying "This device cannot start" (Code 10). Failed to initialize sensor from HID collection descriptor". I am not sure if this is related.

Lenovo Yoga 2 Pro Flex :: Can't Install Windows Updates

Sep 29, 2014

I love everything about my yoga2 pro, except, when I got it I installed a win 8.1 upgrade because windows told me to. everything seemed to be fine.

After that, the system asked me to install another upgrade. when trying to install that one it said it could not install and was undoing the changes. I read some forums awhile back and it talked about a particular update that needed to be uninstalled before you could proceed. I tried to do that, but it wouldn't let me uninstall the initial 8.1 that i installed.
I let it go because it was asking me like every month or so to automatically shut me down and install updates. But now it forces me to install updates every two days and then can't update so, it undoes it changes and it takes like 30-45 minutes or so. Plus, i do need to get it to be able to accept the updates at some point.
I'm thinking I have to wipe everything and start from scratch??

Lenovo Yoga 13 Flex :: Screen Brightness / Flickering

Oct 29, 2012

Loving my Yoga 13 so far have had it since Oct 26th when it was released. Like everyone else I had some issues with partitioning yadda yadda yadda, got that taken care of, but lately I've noticed that my screen brightness seems to flicker, ALL the time, when switching from program to program if the color changes on the screen I notice that the brightness changes as well in noticeable increments. I have the automatic brightness setting set to OFF, so I can't imagine that's the reason.

Lenovo Yoga 13 Flex :: Way To Disable Touch Screen

Jul 26, 2013

I have a crack on my screen that starts in the bottom left and spreads to almost the top right. It is not bad and everything works fine except for the touchscreen. Only half the touchscreen works and sometimes the crack causes the other half of the touchscreen to act on its own and its very annoying and messes me up when I try to surf the web or use Microsoft Office. Is there a way I can disable the touchscreen?

Lenovo Yoga Flex 15 :: Screen Keeps Changing Brightness

May 21, 2014

I have just bought the Flex 15. I looked at the power settings and set the brightness, but it is ignoring the settings and always either darker or brighter than I want it. It keeps flickering between being darker and brighter and it's giving me a headache. It is unplugged if that makes a difference, I haven't used it plugged in yet to know if it does it then. How can I stop it? I've looked through the settings and can't find anything.

Lenovo S440 ThinkPad Yoga S Series :: Install Windows 8 From Recovery Disc In Virtualbox Hangs On Splash Screen

May 13, 2014

when I try to install the Windows 8 copy I got with my Lenovo S440 in a virtual box environment

the installation procedure hangs on the windows splash screen. I never saw a Windows 8 installation

procedure before, so I booted my laptop from the installation media to check if it is corrupted.

This works fine. A loading dot circle is displayed under the logo after a few seconds and than after quiet

a while the lenovo wizard is shown... so it has to be an issue with the virtual box. 

I attached a screenshot to show you where it hangs.

Lenovo 15 Yoga Flex :: Black Screen After Memory Upgrade?

Aug 29, 2014

I have a Lenovo Flex 15 device (i5 version with 4GB ram). I upgraded it with an SSD, reinstalled Win 8.1 in UEFI mode. Everything works fine.
Next I replaced the 4GB memory with an 8GB version (same speed, Kingston) now the machine won't boot anymore, all it shows me is a black screen, both with power switch and novo button. If I reinsert the original ram it boots just fine again. The 8GB ram is not faulty, I tried it in another device and it works. I also tried disabling secure boot in bios but it's the same problem.

Lenovo Yoga 13 Flex :: Black Screen - Bios Settings

Jan 14, 2014

I've been having problems with the dreaded "black screen" when starting my Yoga13 (but only somethimes!). To try and narrow it down, as there seem to be so many things that can cause this, I went into the Bios settings from "F2" and setup it up to ask for a "Power on" password before starting windows.
What I have discovered is that when the black screen occurs its BEFORE the Bios asks for the initial "Power on" password, ie I cannot see the box asking for the password and so Windows has NOT yet started to load. To overcome this, I just press the power button to switch off the system, wait 20seconds and then it will usually start.
Once past this, no errors ever occur on the windows side.

Lenovo Yoga 2 Pro Flex :: Black Screen After BIOS Update?

Dec 10, 2013

I just formatted my yoga 2 pro, downloaded the drivers and ran the Bios Update. I followed the instruction on the read me, ran the .exe, clicked next/ok until the laptop restarted and if I'm not mistaken a red menu with a progress bar showed up. At that point I left and when I came back a few minutes later the laptop was turned on, the screen lighting was on but the display was black, the keyboard backlights were also turned on and everything else was off. The lights on/near the power button that signal if it's turned on and plugged to the AC are turned off.
It's been like this for over 30 minutes now, no signs of progress. I'm not very keen on turning off or unplugging the laptop while flashing the BIOS, but at this point there's not much else I can do.

Lenovo Yoga 2 Pro Flex :: Screen Is Unwantedly Adjusting Brightness

Nov 9, 2013

I've noticed the screen on my Yoga 2 pro tries to automatically adjust the brightness of the display depending on how dark or light the content being displayed is... I want to figure out a way to make it stop. For example, my desktop background is just plain black, and when i got to my desktop, it starts to dim by 4-5 levels lower, and then when I go back to my browser, it reverses and starts to turn up the brightness by 4-5 levels. I've already tinkered with all the power settings and even the advanced power settings to turn of auto dim/automatically adjust brightness etc and all those settings but it still does it.

Lenovo Yoga 2 Pro Flex :: Major Screen Flicker Followed By Black Out

Apr 18, 2014

I don't think this is the same screen flicker that is experienced by the few others due to auto brightness problems...
It's flickering black and then the whole thing turns unresponsive after a while...and although the video shows it happening during a low light environment, i have had this encounter during a brightly lit area as well...

I've posted a copy of what really happens on google drive. Is this a case of motherboard problems? I jsut got my laptop about 3 weeks ago. Any chance for a 1-1 exchange?

Lenovo Yoga 13 Flex :: Lag After Updating To Windows 8.1

May 24, 2010

I recently updated my Yoga 13 to Windows 8.1 and am now experiencing significant lag when resuming from suspend and periodically while I work. Often I will type and not see the text on the screen for another 5+ seconds. 
I have run Malwarebytes and Windows Defender and found no malware. By keeping an eye on the task manager I have not been able to identify a misbehaving process.

Lenovo Yoga 13 Flex :: I5 Model - Screen Auto Dimming Won't Disable

Oct 23, 2013

Just picked up this model from Best Buy yesterday. Like everyone else in the large thread I am having the yellow color issue as well. However, I have another issue that I can't seem to find any information on.
The brightness on my screen is constantly adjusting. It is most obvious when making the move from the desktop to Metro. After hitting the windows key, I can see the brightness increasing in stages (about 4 times) after flipping over to Metro.
I have disabled Auto-Brightness under the Change My PC Setting -> Power and Sleep menu. I have also disabled Enable Adpative Brightness under Windows Power Mangement but the issue still persists.
Is there any other location I might be missing a setting that can be affecting this ? Brightness is set to full and keeps dipping down.

Lenovo Yoga 3 Pro Flex :: Movement (scrolling) On Screen Interferes With Sound?

Oct 19, 2014

Just picked up my brand new Yoga 3 Pro a few days ago and on the whole I love it, except I've just noticed there's an odd issue when listening to music (whether it be local or streaming thru spotify).
If I'm browsing a document in Word or even when accessing the Lenovo Support screen from the Start menu, any left to right horizontal scrolling (either with the touch screen or touchpad) causes a crackling interference to the sound. I did notice it would crackle as the Discussion forum cards were loading up and appearing too. 
It's not the physical speakers themselves because this occurs thru headphones as well. 
Strange thing is it doesn't occur when scrolling vertically through a document. 
On the whole it's not a HUGE problem, but given it's a brand new 2grand laptop, now while it's still brand new and I haven't even had a chance to load much onto it. How to stop this from happening?

Lenovo Yoga 13 Flex :: IdeaPad Touch Screen Not Working After Plugging In USB Device

May 24, 2014

I use a USB MIDI keyboard (Akai LPK25) with my Ideapad. I've not previously had an issue with this configuration, but since about a week ago, as soon as I plug in the device the touch screen becomes disabled. Removing the device doesn't restore touch screen functionality; I actually have to reboot.
Was there a recent USB upgrade that's causing this issue?

Lenovo Yoga Flex :: IdeaPad Does Not Switch On - Shut Down In Windows 8.1

Sep 19, 2014

My Lenovo Ideapad Flex laptop does not switch on when I press the power button.  It was working till this morning, when I switched it off (via an operating system shut down in Windows 8.1). When I tried to turn it on an hour later, I found that pushing the power button has no effect at all. 
I tried pushing the novo button.  In this case the laptop does turn on and shows the "lenovo" welcome screen for a few seconds.  However, it promptly switches off again.  The symptoms do not depend on the laptop being connceted to power: they are exactly the same in the two cases.

Update your Chrome browser to Version 37.0.2062.94 m and above ... It works fantastic with the Y2P and the text is so sharp now for high res laptops running Windows ...

I've just updated mine 15 minutes ago, haven't come across any bugs or usability issue.

Touching on the screen when typing still does bring up the OnScreen Keyboard ...

Oh well ... At least the text is much sharper now compared to the previous versions of browsers ... I have a Y2P (i5) ...
