Lenovo Yoga 2 Pro Flex :: Micro HDMI And Bitstreaming HD Audio To AV Receiver
Apr 26, 2014
I have an A/V receiver which supports HD sound up to DTS-HD MA and with my old laptop I was able to bitstream DTS audio from movies with an optical toslink cable. When I saw the Yoga 2 Pro laptop had a microHDMI port, I assumed that I would be able to get DTS audio and maybe DTS-HD and DD TrueHD audio from HD movies by bitstreaming it to my receiver. I've only tried it with VLC and where I was able to get the spdif pass through working for DTS audio before, this has not proved straightforward with this laptop. Trying passing the audio to their receiver to get HD audio? Is this generally not possible with laptops?

My new Yoga 2 Pro has a secondary display connected through the micro HDMI port. This worked like a charm initially. But after upgrading to newest Windows 8.1 (this is done automatically) it no longer outputs anything to the micro HDMI port. Display and cable is fully functional. But even though the display is powered on, the computer fails to register it and apparently it cannot output anything. Seems like the micro HDMI port is non-existing.
After the windows upgrade I have tried to uninstall / reinstall the display driver. I have also upgraded the Intel drivers to Win 8.1 versions found on the Lenovo support site (including BIOS 76CN38, Intel HD 4400 display driver 15.33.18.64.3496 and chipset 9.4.0.1026). But nothing seems to work.

Just bought my Yoga yesterday and am thoroughly enjoying it. A problem I encountered was when trying to pair the Bluetooth to a Belkin A2DP receiver (essentially, it appears as a Bluetooth audio headset to the computer). Audio quality sent to the speaker is very poor. I verified that the Belkin unit was functioning properly by pairing two other Bluetooth devices and having no issues with audio playback. I also updated to the latest RealTek Bluetooth driver on Lenovo's website. Still with bad audio quality.

I´ve got a problem when I connect the yoga 2 pro with my TV (8 year old sony, full hd) with HDMI. The picture doesn´t fit into the screen, it is too big. I tried changing the resolution of both yoga and tv and at the Intel graphics driver I can´t change the scaling option. H

I have a yoga pro 2 and I want to connect to an external monitor. I bought a mini HDMI to HDMI cable. Video is perfect but no sound. If I plug into a TV the sound comes from the TV so cable is OK. Can I change the settings on the Yoga to allow the sound to come from the computer speakers when plugged into an external monitor using mini HDMI?

I have a brand new Yoga 2 Pro that has an audio jack problem. The internal speakers play audio just fine. When I plug in a pair of headphones into the jack on the right side of the unit, no audio comes out of the headphones. The internal speaker continues to produce audio as if there is nothing plugged in.
Failed solutions:
I've tried using various types of headphones. No change.
I tried re-downloading the audio realtek drivers from the lenovo website and re-installing them. No change.
I tried rolling back the audio driver to the Windows version. No change.
Is there anything else I can try? Non-working audio jack makes this a dealbreaker and I'll need to return the unit.
Update: According to Lenovo phone support, all my headphones are 3.5mm and they need to be 2.5mm. Frankly, I think they have it backwards and what I have are 2.5mm plugs, but either way I'm headed to radio shack to find an adapter to make this work.

So the Yoga 2 Pro's single 1'8" audio interface is billed as a "combo" jack that functions both as a line-out (for headphones, speakers) and a line-in (for plugging in other audio devices to play through the computer's internal speakers). Well, this doesn't seem to be the case - I've tried ini vain to do this with a Line 6 guitar interface with no luck whatsoever. The Realtek Audio HD software shows the jack as performing two functions, but you cannot change what it's being used for - a difference from earlier versions of the Realtek software (apparently this was most easy to change in the Windows XP version).
How I can properly configure the combo jack to work as a line-in port, as was advertised when I bought the computer?

I upgraded to WIndows 8.1 a few hours ago (available in Store). However, ever since the upgrade I can no longer watch videos or hear sound in all Apps.
Netflix gives me a message that there is a problem with this system's configuration that prevents Windows from playing protected video and error code W8156-8007007E.
Xbox Music player gives me "Can't play. Make sure your computer's sound and video cards are working and have the latest drivers" error code 0x00d11d1 (0x8007007e).
All the other Apps that have video, and or audio, give various errors messages (e.g., "The video failed to play".
Now I can watch imbedded You Tube videos in Internet Exployer.
I did find KB2756872 that seems to address the problem with protected videos not playing. However, it doesn't mention if it is compatible with Windows 8.1 and when I follow the manual update method where you make changes in Regedit. I did not see the key that needs to be deleted.

Yoga S1 output audio through the mini HDMI port? I see it listed as a possible output in "sound", but it just says "not connected". Not sure if it is my TV, my laptop, or the HDMI to mini HDMI cable I'm using.

Well, didn't check before installing Macrium Reflect Professional but it detected 7 (seven) partitions in my Yoga2 13 (Not Pro) as follows:
1 - WinRE_DRV 1GB total 313MB used - NTFS Primary
2 - System_DRV 260MB total 28.5MB used - FAT32(LBA) Primary
3 - LRS_ESP 1GB total 497MB used - FAT32 (LBA) Primary
4 - NONE Unformated Primary (?)
5 - Windows OS 422GB total 44.58GB used (C NTFS Primary
6 - Lenovo 25GB total 2.46GB used (D NTFS Primary
7 - PBR_DRV 15.75GB total 12.46GB used NTFS Primary
All Yoga2 13 are like that from the factory or Macrium created some of them? If they are like that from the factory what each of the partitions have inside (other than, obvlously, the #5 Windows.)
In creating an image for restore in case one is needed which ones I should include in the image?

Is there any way to boost volume on Yoga 13?? I have my system volume and video player volume maxed out and it's STILL not loud enough. No it doesn't have anything to do with what I'm watching, and no, nothing to do with the player. Windows Media, VLC, and Divx have been tried.

I purchased a new Flex 2-15 online the past week. The model name shown on the back is "20405". Manufacture date is May 12, 2014. The User Guide refers to a "Novo Button", which is shown in diagrams as being on both the left edge and the right edge near the front. Neither location has a button of any sort. The right edge has a pinhole in the supposed button location. A curved arrow icon is next to the pinhole. I have an inkling this may be some sort of factory reset button. Lacking the Novo button, what is the procedure for accessing the features which the manual says are accessed by pressing this non-existent button?. That is, BIOS, and/or the one touch image backup/restore system?

I got my new Yoga Pro 3 and it is looking and working great except from the two fingers tap which does not. This is a real bummer since I use it all the time on my mac and Asus devices.

I paid $60 just for some recovery discs to recover my accidentally formatted Yoga 2 Pro. The discs came with no instructions whatsoever, and using them is weird. First of all, there is two disc 1's, no disc 2, yet there is a disc 3 and 4. Support confirmed this is normal. There is also no prompt between discs 1,1, and 2, so despite making my best guess at when to switch, I can't confidently say I'm not screwing things up.
After the whole process completes, the bios can't find bootable media.

I had bought yoga 2 pro from Malaysia three weeks back. And I had traveled back to India last week.The PC was working fine till yesterday. Yesterday while I was working suddenly the system hangs and I had to hard reset. But after that the system didn't boot up. It shows boot device not found. I have switched it off and tried booting using restore button and opened the bios it shows that HDD not detected.
Similar kind of issue I faced two times before but if I hard boot again it worked fine.

I just had my Yoga 13 for about two months and really liked it. Upped RAM to 8GB and added the second SSD. Sweet.
But now I managed to nearly brick my nice little Yoga by spilling juice all over it, and now I am in recovery process.
I checked the original mSATA SSD on another machine, and it looks like it still works fine, all partitions are still there.
In the very beginning after first "drying" the Yoga I got it to boot a couple of times. But now all I get is "Default Boot Device Missing".
Next thing I'll try is putting the SSD in an external USB enclosure and try and boot from there.

I just got the Yoga 2 Pro and it seems like a great laptop / tablet. I have one big problem: the touchpad is near-unusable for me. It seems like I'm constantly activating the switch app gesture and just cannot use it.
How do I turn off all of the gestures on the touchpad so that it just functions like a normal mouse????

I've got a Yoga 11s which is barely a few months old and hasn't seen much use. Having the same problem - it won't power on or charge (powers on only when plugged in). In Lenovo Energy Manager battery status shows "Good" and charging status shows "Battery Connected". WIndows power management icon however, shows Plugged-in, not charging. Never had that problem before either, but it came with the power-on failure so I guess they're related.

I cannot get the Y2P to shutdown or sleep. When I try to shut down it powers off but after about 2 seconds it turns itself back on and boots up. Same thing happens when I try to sleep.I've tried pretty much everything I could find online including the following:
-Turn off wake on lan on the network adapter
-Turn off auto restart on windows errors
-Updated bios
-Updated drivers
-Disabled all non microsoft services
-Factory reset of the OS
Went through every device in device manager and turned off "Allow this device to wake the computer"powercfg /lastwake (shows nothing).Shutting down isn't a huge deal as holding down the power button will eventually turn it off. But not being able to sleep the laptop when I close the lid is a deal breaker as the battery constantly drains.

I just got the Yoga 2 Pro, I also have an older Thinkpad 65W 20V AC adapter with a ThinkPad Slim Power Conversion Cable, so it will fit, but is it ok to use? All the specs match except my new Yoga 2 adapter doesn't have the wattage listed on it.

I just bought a Lenovo Yoga 2 pro and installed windows 8.1 by itsef. During Windows 8.1 initial setup I was able to use keyboard to type in PC Name, but after that the keyboard and touch pad was not working/no any response any more. After Windows 8.1 lunched the keyboard also no any response. I have to use touch screen soft keyboard. But when laptop in BIOS mode (turn power off and press a small round button next to power button) the keyboard was working fine. So I think that the keyboard hardware is ok, but some thing iwas wrong with Windows 8.1 software issue. I also un-selected all on Easy of Access->Keyboard section in Windows 8.1.

I have the issue that my newly bought Yoga 11 (three weeks ago) is charging whenever it seems to feel like. The first time I have charged it, it went up to 92 % telling me its now in power state and not charging. This happened triple. Yesterday my Yoga was beneath the 50 % mark and I plugged in the powercable, the same again: not charging. I unplugged the power cable and at 0 % and a shutdown I booted it and it charged perfectely up to 99 % without moaning. I unplugged the cable and at 77 % the same again, I plugged in the power cable and it charged up to 99 % again.
Is this a bug (battery problem) or a feature (thresholds for a long living battery)?

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.
