Lenovo Yoga Flex 2 :: System Crashes - Data Lost
Nov 15, 2014
I bought this laptop 1 WEEK ago. 2 Days after purchase it crashed. Unable to get back in... tried turning on and off numerous times. Finally able to reacess, but system completely reset itself to factory settings. Thought it was a glitch..Its a brand new computer.. 3 days later, same problem. Finally able to get back on, through system repair, but all data is lost AGAIN. System update search states that "there has detected a serious problem loading language files and cannot continue. Please contact Lenovo Support Center" Also, touch screen no longer works.This is a brand new computer!??

After I open the lid and the tablet starts getting out of sleep mode, the blue screen appears with the following error message:
SYSTEM_THREAD_EXCEPTION_NOT_HANDLES (rtwlanu.sys)
What is causing this and how to resolve it?

I lost the restore partition on the original SSD that my Yoga 13 shipped with. Is there a collection of drivers and whatnot that would allow me to restore it to factory defaults on my own with a fresh windows installation? I have the win8 key from the BIOS but don't want to lose out on all the required drivers if I were to just reinstall windows myself.

Am I right in thinking that because System Update is not supported for the Yoga 3 Pro, the new tool for updating the system is the OneKey Optimizer?

After doing a system backup the intel wireless n7260 disappeared. I reinstalled it under device managers action and the driver got installed as (2) and not working, meaning the driver 1 must be actually there but is not visible and also not working. I therefore cant get an internet connection or see any available wireless networks. How to get this driver working again?

I wanted to do a fresh install but my restore files are in Windows 8 and I wanted 8.1. I used my 8.1 pro disk and created a bootable media for installing using USB. I had to go into the BIOS and change it to legacy before it would see the USB drive. Went ahead and deleted all the partitions then created a single new one for windows. The installation worked flawlessly then I went ahead with the driver installs.
The very first driver was the firmware update. The system updated the firmware without any issues but once it rebooted I only receive the following message "Default Boot Device Missing or Boot Failed. Insert recovery Media or hit any key. The select 'boot manager" to chose a new boot device or to boot to recovery media. When I go hit any key it leaves me with no boot options probably due to them being legacy options. I've tried F2 on startup to get into the bios and change it back to legacy but this never works.. I have also tried F12 trying to get it to let me select the startup drive.

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´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 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.

I own a Lenovo Yoga 2 Pro (Model 20266) with a stock 256GB Samsung SSD MZMTD256HAGM-000L1. It works well in general, but occasionally it'll freeze for several tens of seconds, particularly when I'm idling or working on something that doesn't use the hard drive. I thought it was an issue with the SSD going to sleep, but disabling hard drive sleep via the Windows Power Options doesn't work. I've tried installing Samsung Magician, but it doesn't support the drive even though it detects its a Samsung SSD.
Is there some setting I need to disable? Failing that, is there some way I can upgrade the firmware? This model doesn't appear on Samsung's website either.

I just got it about 2 weeks ago and it's all booger up. I think I accidentally installed some malware and it now there's stuff I just can't get off it. I've been running windows 7 for years and never had malware issues like I'm running into on 8....
Since there's no DVD drive and it didn't come with a system restore thumb drive like my mac air did, how do you do a full factory reset?

My battery is at 0% available, plugged in charging, but it never goes about 0%. I've tried resetting the battery gauge in Energy Manger 1.0.1.49 but that only runs for a few seconds and reports that the gauge reset is complete. I've also disabled the ACPI control in device manager then enabling it and the icon appears to be charging but only for a few seconds then stops. Having conservation mode on or off doesn't seem to make any difference.
The latest BIOS is installed and I believe I have the latest version of Energy Manager.

After applying the latest BIOS patch (76CN38WW) I've noticed a degradation in performance.
Looking at task manager I see cpu speed fixed a 0.77 GHz and looking at resource monitor I notice only CPU 0 with any load the other 3 cores appear ideal (disabled?)
Power plan is set to performance and is on main power.
