Yoga 2 Pro Brightness stuck at 100%

Hi,
After the last BIOS update my laptop brightness is stuck at 100%.
Lenovo tech. did remote access and reinstalled Graphic drivers and changed registry for brightness and that didn't work.
He told me I will have to send the laptop in and they would have to reset the BIOS manually there to fix the issue and that everything will get wiped out.
Has anyone else had the same or similar issue.
If yes is there any other fix?
Thank u guys.

Hi
have the same issue, cannot change brightness since yesterday, it is stuck at 100%, brightness keys don`t do anything, in Charms bar brightness level shows a lock.
But it all happened WITHOUT the latest bios update and before latest grahics driver from Lenovo website was installed!
I even made the bios update and tried all newer/older graphics driver in hope of a change. but nothing changed. Unfortunately my Windows recovery points from days ago are showing errors, so i can`t go back a few days, can only try to refresh windows if there is no other solution...
Any help??

Yoga 2 Pro Windows 8.1 stuck in automatic repair loop

So my Yoga 2 Pro is stuck in the (in)famous Windows 8 Automatic Repair Loop, and I'm not sue how to fix it now. I unfortunately neglected to create a Recovery USB stick, so what are my options without it?
I've already tried booting the computer with the Novo button and choosing System Recovery, but at that point the system goes right back into the Automatic Repair loop. I'd strongly prefer to back up my data before resintalling Windows if that's an option--is it possible to stick the SSD into another computer to do so?
Also, would a USB recovery disc created by someone else with a Y2P be useable on my system? I don't need the full partition image since the one already on mine should suffice. I'm also unsure of my system's Windows 8 Product Key, where can I get that if/when I do need to reinstall Windows?
Thanks for any help, it's greatly appreciated.

First and foremost, good luck:
Method 1:
Wait for the machine to boot into the 'Automatic repair couldn't repair your PC' error message.
Click the 'Advanced Options' button
Open cmd and type:
bootrec /fixMBR
bootrec /Fixboot
bootrec /rebuildBCD
and also
chkdsk /r c:
chkdsk /r d:
Method 2:
https://www.youtube.com/watch?v=iNKEsOF7e4M
Method 3 (copied from a youtube comment):
1. Turn on the computer.
2. Wait for the machine to boot into the 'Automatic repair couldn't repair your PC' error message.
3. Click the 'Advanced Options' button
4. Click the 'Troubleshoot' button
5. Click the 'Advanced options' button
6. Click the 'Startup Settings' button
7. Wait for the system to reboot into the 'Startup Settings' menu (is the same menu for safe mode)
8. Select the 'Disable early launch anti-malware protection' option. (Press '8')
9. If this worked for you, you should now boot into windows.
10. Now you can shutdown your system and it should hopefully work first time the next time you start the system.

Yoga 2 Pro stuck volume, missing cursor, onscreen keyboard unusable

I'm having several issues with a Yoga 2 Pro laptop running Windows 8.1 that's about a year old.
1) Volume is stuck at 0. I can raise the volume, but it automatically lowers back down to zero, as if the volume-down key is stuck. The volume indicator is always onscreen.
2) Cursor is missing, however I can still right click/left click. Also, the cursor will reappear when I uninstall the Synaptic touchpad drivers.
3) The onscreen touch keyboard is unusable. I can click on the icon and it pops up, but it immediatly goes back down.
4) Side screen charms won't stay on screen (example: pressing the F10 key or project screen the side menu pops in but immediately pops out, similar to the keyboard). Also if I swipe in from the right and try to use anything (devices, settings, etc.) it does not respond
5) Pressing the start key doesn't bring it to the start screen, but holding it down for a few seconds does.
The above problems still exist in safe mode.I'm thinking it's a hardware issue or a bad connection of some kind. I've tried:
1) Removing/reinstalling various drivers (touchpad, audio, graphics)
2) Disabling services (YMC comes up often when looking at trackpad problems, but this hasn't worked for me)
3) Uninstalled/reinstalled programs (Energy Management, Transitions, etc.)
4) Did a complete factory reset at one point, had no effect.
I've had the problem a couple times before, and one thing that DID work was to hold down the power button for ten seconds while the computer was off, then let it reboot. Unfortunately that solution is no longer working. The threads I've linked below have been the closest I've found to a problem like this, but neither of their solutions worked for me.

Any help would be much appreciated! Definitely affecting my usability of this otherwise wonderful machine.

Update in case anyone else comes across a similar problem: I ended up sending my laptop into warranty, and it came back a week later working completely. No idea what the problem, cause, or fix was, although they didn't replace any major parts (battery, cable, cpu, fan, hard drive, keyboard, touch pad, display, memory, motherboard...going off the list they sent back, none of those were replaced), so I'm not sure what to think. Not even a factory reset. I'd love to know what the issue was, in case it comes up again but am happy that my laptop is once again functioning in either case!

Guilherme1010,
Welcome to the forum. I see that you left this comment on this KB article on autobrightness and so I moved it out here so that others in the community would be more likely to see it and chime in with suggestions.
If you have not installed your own applications or data yet, and you are having issues with the system not responding to check for updates even if there is internet connection, and not opening settings, then you can try to debug this, or you might consider doing a system reset to restore to factory condition.
Sometimes, the preloaded image gets corrupted and can just be reset, and then will work fine.
Here are some instructions on how to reset. http://windows.microsoft.com/en-us/windows-8/restore-refresh-reset-pc
I realize this may be a bold step, and it will wipe out all data and settings on the system so make sure you are ready to do that.
Best regards,
Mark

MacBook Pro battery level indicator is stuck at 100%

Got this MacBook Pro in January of 2008. Great machine, replaced battery last spring and more recently had some sort of repair done when the screen would not activate. No problems otherwise. Now all of a sudden my battery level indicator is stuck at 100% regardless of actual battery charge level. The computer will allert me that it needs plugged in immediately or it will go to sleep, but it would be nice to have the indicator working again. Any ideas?
JG

If it's a pre-unibody MBP with a removable battery:
1) Shut the computer down
2) Disconnect the Magsafe AC adapter
3) Remove the battery
4) Hold the power button down for 5-6 seconds
5) Reinstall the battery.
6) Connect the Magsafe adapter to power and turn the computer back on.
This will reset the System Management Controller. One of the SMC's functions is reporting of the status and remaining charge of the battery.

Yoga 2 Pro - Light bleed on screen - is this acceptable / normal for this screen?

Hi all,
I wonder if someone could give me some advice as to whether the light bleed I'm experiencing on my Yoga 2 Pro is 'acceptable'. It doesn't bother me in normal day to day tasks like office work, email, web browsing but it's pretty distracting when watching videos in a dark / dim room, particularly where the video itself contains dark scenes or letterboxing.
I've done a bit of searching on the web it seems that black light bleed is a pretty common issue with these types of displays.
The following photos were taken on a DSLR in a totally dark room whilst running a video of complete black on youtube:
Brightness 100% - overexposed a bit in camera to show main areas of light bleed. The lower right corner is the most severe. Light bleed is also quite prevalent along the bottom of the screen.
Link to image 1
Brightness 70-80% - exposed to represent as closely as possible what i see when watching the black video in a dark room.
Link to image 2
Brightness at 50%
Link to image 3
Would this light bleed warrant a return? I bought this from John Lewis in the UK and they have an excellent returns policy. I do love the laptop but the light bleed is pretty annoying. I've seen some images of other peoples light bleed and I worry that if I was to get this replaced I may end up with one with much worse light bleed than what I currently have.
Any thoughts and advice would be most appreciated.
Cheers.
Moderator note: large image(s) converted to link(s): About Posting Pictures In The Forums

Ok, I think I have identified the source of the light bleed from the top right corner. It seems that whatever they use to glue the panel down to the backing has loosened. If I press down on the top left corner of the screen it is rock solid. If I press down on the top right side where the light bleed is it flexes downward. When I push down on the border the light bleed disappears.
So it would appear I don't have a panel problem, I have a glue problem. Bummer. Will contact Lenovo today. Hopefully getting this fixed won't involve sending my Y2P into some shop for 3 weeks.
The light bleed sucks but what concerns me more is that the panel's integrity seems to be failing and could get worse. I hope Lenovo has a local shop that can take a look at this.

Best feature of Yoga 3 Pro? What would you change?

For those who have Yoga 3 Pro systems, what do you think are the best features after having used it for a while?
What new features or changes would you want to see on future models?
Thanks!

Hello,
I have mainly used my Yoga as a document creation station (Microsoft Word, Microsoft Excel, Microsoft PowerPoint, etc.), so I am looking at it from that perspective.
The Good:
Screen is bright and high enough resolution so that I can see a full page of information.
System does not weigh much (but see below)
The Meh:
function and meta keys missing. making it harder to use Microsoft Office
yet another keyboard layout to learn
no TrackPoint (I find the touchpad so abhorrent that I use a Lenovo N700 wireless mouse)
Micro HDMI port
yet another one-off power supply connector
I'm concerned about how this notebook computer will last over the long-term; while it seems fine, so far, it is so thin that I'm concerned it is not very durable
the external AC adapter (see below)
The Asks:
Frankly, I would be happy to have a thicker, heavier unit. Adding a few millimeters to the thickness and a few 100 grams to the weight would be fine by me. It would make the unit appear more solid and less likely to break.
Can I have te function keys back, please? Also meta keys (PrtScn, ScrollLock, SysReq, etc.)
Can you please standardize on a power connector and use it across multiple lines and models?
Standardize on one video conector so each laptop doesn't have to get a bespoke set of adapter dongles. My preference would be MiniDisplayPort, as adapters for that are much easier to locate than for Micro HDMI.
The "wall wart" style AC to DC transformer is very small and does not take up a lot of space. It is also impossible to plug into many AC outlets that use decorative outlet covers, like my local coffeeshop chain does. As a result, I now have to carry an additional short AC power extension cord with my notebook computer. Frankly, I'd just rather have something like Lenovo's own Ultraslim AC adapter, with a detachable AC line cord. As an added bonus, if I travel to a new country, I can just get a new AC line cord conformal to local power outlets, and be up and running in no time.
Recovery media would be nice. Even DVDs are okay, since external USB DVD±RW disc drives are plentiful and inexpensive.
That is all I can think off off the top of my head.

Aryeh Goretsky

Yoga 2 Pro - Broken in less than a year - A terrible experience with IdeaPads

Hi guys!
I'm hear to tell everyone about my pretty terrible experience with Lenovo and my Yoga 2 Pro IdeaPad. It's not a review or anything but more of a forewarning to those who are thinking of buying from Lenovo.
I'm also here to help others out in my situation, that is, if you are stuck with a half broken (or in my case, completely faulty) laptop and Lenovo won't help you out (fixes are in italics).
The beginning
So I bought a Yoga 2 Pro at BestBuy in the USA about a year ago. I live in Australia so I asked about international warranty and they said that the notebook is covered by international warranty.
The day the screen flashed black and white
About a few months in the screen began flashing black and white rapidly (it goes from black to white about twice a second) for about 30 seconds to a minute. I found that you can stop this from happening if you open and close the lid a couple of times. Not really a big issue unless you set your laptop to go to sleep/shutdown when you close the lid. I don't so everything was fine.
The day the Wi-Fi NIC stopped working properly
So then a couple of months after that my Wi-Fi began to play up. I recently found out that you can prevent this from happening by ensure that you don't put any pressure on the sides of the base of the laptop (Eg. don't put your elbow on the side of the laptop and hold your head up with the same elbow).
I also worked out a while ago that you can get the Wi-Fi to work again if you go Right click Wireless Icon->Network And Sharing Center->Change Adapter Settings->Right Click Wi-Fi->Disable it->Renable it
Here comes the bad stuff...
Screws began to fall out
So then the screws began to fall out. I screwed a couple back in when they were wobbly but they eventually fell out without me realising. This suggests that the screw holdings have poor quality threading and as a result the screws begin to fall out. I now have 5 out of 11 screws on the backplate of notebook.
And also the screw holdings.
Yup, the actually thing that the screw screws into fell out as well. About three of them fell out. I don't know how it could possibly do so but it did, it happened when I picked up my laptop from the desk.
And then the charger socket broke
I can no longer charge my laptop -> I now have a very expensive beverage coaster
So then the charger socket cracked in half too! Again, not really sure how it happened but it did, it might possibly be from the heat of the laptop causing the plastic to expand when heated and retract when cooled. I have the i7 CPU version so it may get hotter than normal.
The laptop no longer charges so I no longer have a laptop to use (I use my desktop to work (and occasionally my phone)).
Not to worry! I'll just make use of my international warranty...?
And then the customer service were not helpful:
And then they said I didn't have international warranty...
And then they admitted that I did...
And then they claimed international warranty does not apply in Australia...
So I emailed Lenovo customer service and they kept claiming that my notebook did not have international warranty.
I talked to Jessica, Jason, Jai, Jasmin, Jackie (why are there so many J's?) and Adam.
Eventually one of them admitted that I do have international warranty but it is not supported in Australia. How convenient for them.
The notebook has never been dropped
I am the only user of the notebook
The notebook is kept in a padded laptop bag.
I was very polite to customer service.
All I'm left with is a very expensive notebook that doesn't actually work.
As a result I can only strongly recommend that you avoid buying from Lenovo. I worry for those who have bought Yoga 3 Pro, with it's watch band design and all.
Here are some pictures I took a few weeks ago (I photoshopped the stickers out):
This is what the charger socket looks like now (Hard to take a good picture, sorry!) Note that it ha...
6 Missing Screws, 3 Missing Screw Holdings
This is what happens when you open the laptop
Hope that cuts down your options when you go out to buy a laptop! Have fun deciding!

Same issues with my Yoga, from India.
Screen (twice), wifi, charger and battery issues, SERVICE issues, no screws in the back...
Beside that my laptop USB and bluetooth is also not working and it is soo slow...
I just bought a non lenovo charger.
Yes and my laptop never left my office table.
I was hoping to fix it in Australia and I guess not.

Yoga 3 Pro or Yoga 2 Pro? Opinions from dual owners please

Hi,
I'm tossing up between the Yoga 2 Pro and the Yoga 3 Pro.
I like the design of the 3 very much, and the weight.
I will run Ofiice apps, Photoshop CS6 on the road, and lightroom 5.7.
Any pros and cons from dual users with experience of this software in daily use would be apprecited.
Regards,
David.

I will be doing a video review on my experience soon but here are some points I can tell you already -
1) It is a great travelling companion, movies, videos, songs, small gaming is all perfect.
2) Battery life is really nice, I watched 3.5 hour long Lord of the rings and still had about 60% left
3) Pretty light and rotates 360 degrees, very comfortable to use in any and every mode.
4) Does not get hot, remains cool.
5) Exquisite looks especially the Bright orange color, which is my fav.
6) Screen is beautiful and everything is crisp (I use it at 1080p)
7) Some apps are very useful like ShareIt, transfer data from android, iphone etc in seconds over a wifi network.
8) Performance is good for browsing as well.
9) Boots in 3-5 seconds
10) Keyoard is backlit and very nice but shallow, trackpad is an absolute delight.
2 finger taps, 2 finger swipes, 3 finger swipes, 2 finger zoom, 2 finger scrolling of pages, everything is smooth and responsive.
11) Sound quality is awesome as well, very loud and clear. Enough bass to provide enjoyable experience.
What you should not expect -
1) Heavy graphics intensive tasks.
2) Lags a bit on some web pages scrolling (NOT noticeable)
3) Some software which are useless and can be uninstalled.
I typed this whole post on my Yoga 3 Pro and it is a great for me to type on this beauty.

Yoga 3 Pro Brigtness Keeps Resetting

I've been having this problem with my Yoga 3 Pro whereby my screen brightness will reset to a very low value every few minutes, no matter how often I try to change it. Whether or not i change it in the charms menu, in the Power Options menu on the control panel or otherwise, it always resets to an annoyingly low brightness level within minutes and I have no idea why. I've searched online and none of the solutuions I found worked.

Yoga 3 Pro Touchpad "Momentum" or "Inertia"

The Yoga 3 Pro appears to use a Synaptics touchpad driver. I have used a Dell at work and an HP at home both using Synaptics touchpads as well as my wife's Toshiba Satellite. The device drivers for these offered "Momentum" which, once you get used to, you can't live without. Momentum allows you to flick your finger a little in a direction and the mouse cursor will continue in that direction across the screen until you touch the touchpad again which "catches" or stops the cursor movement and you can resume moving it to its final destination. The Lenovo Yoga 3 "Synaptics" touchpad driver does not offer this option in its settings. Does anyone know of updated drivers that will provide this capability?
I have looked a little deeper (into the registry) of the other computers and have found some settings that seem to enable it in the current driver (Synaptics 18.0.7.85) - MomentumMotion (setting to 1 enables it) as well as MomentumMotionFriction. No wonder it is disabled by default and no setting in the GUI to turn it on - it is very erratic and barely works (sometimes works a little if you make a very long pass across the touchpad and not too quickly before letting go). It is very unusable as it stands in this driver.
If anyone has any information on how to enable this feature properly through a proper driver that works, please let me know. This one feature really makes or breaks using a touch pad all day without getting so "tired" in the hands, fingers, and wrist. Even though it is a touch screen, it is just awkward to poke at the screen when in laptop mode with such a nice and light laptop

Yoga 2 Pro - Frequent issues after Tablet Mode and Suspend in Windows 8.1

Hi,
I bought a Yoga 2 Pro running windows 8.1 in December 2013. The machine runs fine, but from the beginning I experience frequent system issues whenever I have the Yoga in Tablet mode (display turned to the back).
The issues sometimes arise directly after I resume from tablet mode. More frequent the issues appear once I had the machine in tablet mode and after had it in suspend mode!
Some of the frequent issues that arise after I resume from tablet mode:
Power surge at right USB Port, where I have my mouse connected! The connected device cannot be provided with enough power. (Note, the left port still works), or
WiFi not working any more (No WLAN device detected, WLAN not functional), or
Bluetooth not working (No Bluetooth device detected, BT not functional)
All issues reliably disappear with a system restart!
I have already updated my drivers, scanned the Lenovo and Microsoft forum whether this is known without success and hope this avenue will bring me more luck.
What makes the bug hard to narrow down is that I do not have a recipe to reproduce the error. Not every time I turn the display in tablet mode the symptoms are equal! But what I can is that the tablet mode is the most common denominator I found so far.
Any helped/suggestions much appreciated.

Yea, great... it seems like these articles and suggestions come up in the forum, and then there is always someone that says "it didn't work but this solved it for me" which ammounts to setting the screen at full brightness all the time.   LENOVO, HOW ABOUT FIXING THE ISSUE!!! It definitly has something to do with power, in my case _the only_ thing that fixes it is either plugging in a power cord or closing the screen, reopening it and hitthing the power button to turn it back on (both are REALLY annoying if you're trying to get work done).
I'm a fairly experienced IT guy, and I used to swear by _IBM_ Thinkpads and related laptops, then when they went to Lenovo a few years ago it seems like the support has gone to hell and the hardware appears nice but is sketchy (this thing should have never shipped with this display problem or the wifi card issues that it shipped with).   Honestly if issues like this don't get resolved Im not likely to order any more, ever. Not for my self or for my organization, we will stop persueing contracts with you and certifying the hardware for our work (though with the lenovo purchase it was deemed that the hardware wasn't certifyable for certine applications anyway). Yes, that will cost you a few thousand sales a year, which is a drop in the bucket for you, but I'm sure I won't be the only one.

Yoga 3 Pro lmcfrundll.exe Run Problem, how to fix?

While Lenovo is in the process of developing a solution, an official work-around to the automatic update delivered on February 7th to Yoga 3 Pro laptops bas been released to address the following errors:
lmcfrundll.exe application error   unable to start correctly (0xc000007b)
problem starting c:\program files\lenovo\communications utility\libstartstub.dll specified module could not be found
Please note this is a work-around, not the final solution.
It is intended for Yoga 3 Pro systems running Win 8.1 on Lenovo Settings Dependency Package version 2.3.1.30 only.
The readme file and work-around can be obtained here:

Thank you,

Solved!
Go to Solution.

I have a Yoga 3 Pro, Windows 8.1 Pro x64.
There are errors in the Event Viewer related to the problems of LMCSTART1, LMCSTART2, LMCSTART3, which I will cut and paste below. These are there because they are failing to load as the error message on the pop-up window states.
As for the libstartstub.dll "specified module could not be found", there were not errors or warnings in the Event Viewer related to this, but I have noticed that if I disable LENOVO.TPKNRRES from running (via OneKey Optimizer), that particular error doesn't come up.
Here are the errors now from Event Viewer:
Event ID 1005 (same error listed 3 times as an Application error, with a different RecordID listed below)
Windows cannot access the file for one of the following reasons: there is a problem with the network connection, the disk that the file is stored on, or the storage drivers installed on this computer; or the disk is missing. Windows closed the program Lenovo® Multimedia and Communications Framework Custom Rundll because of this error.
Program: Lenovo® Multimedia and Communications Framework Custom Rundll
File:
The error value is listed in the Additional Data section.
User Action
1. Open the file again. This situation might be a temporary problem that corrects itself when the program runs again.
2. If the file still cannot be accessed and
   - It is on the network, your network administrator should verify that there is not a problem with the network and that the server can be contacted.
   - It is on a removable disk, for example, a floppy disk or CD-ROM, verify that the disk is fully inserted into the computer.
3. Check and repair the file system by running CHKDSK. To run CHKDSK, click Start, click Run, type CMD, and then click OK. At the command prompt, type CHKDSK /F, and then press ENTER.
4. If the problem persists, restore the file from a backup copy.
5. Determine whether other files on the same disk can be opened. If not, the disk might be damaged. If it is a hard disk, contact your administrator or computer hardware vendor for further assistance.

Yoga 3 Pro DirectX/Direct 3D Error

I have a Yoga Pro 3 which routinely crashes a few minutes into Neverwinter game with the following error:
Fatal Error: Direct3D driver returned error code
(DXGI_ERROR_DEVICE_REMOVED) while checking sync query
Technical Details: sync query 0 0x15ddf780 GetData == 0x887a005 0 NF 0
D3D11 Device removed due to E_OUTOFMEMORY 0x8007000e
A printout of DXDIAG is appended below.
Things I have tried:
- made sure I had the latest video drivers from Intel for the 5300
- research on the above code suggests that the last driver that would not crash on a particular game was 9.17.10.2932 in December 2012 LINK: https://communities.intel.com/thread/46821 I was not able to install that driver but I was able to roll back to a generic driver from 2006 that seemed to extend time until crash from 5 min to at least an hour. At some point system put latest Intel driver on again so I dont know if old driver ever crashed.
- installed latest video drivers from Lenovo which are a few months older than the intel drivers even though they were posted later than most recent intel drivers
- worked through several solutions with tech support from Cryptic/Neverwinter which led us both to the conclusion that this is a video driver issue.
Help will be appreciated.

**INFO OMITTED FOR BREVITY**

I have a similar issue with my Yoga 3 Pro. I play Runescape with the desktop client, which is Java based. I regularly encounter driver crashes. Every time this happens, the driver recovers, but it causes the game to go black for about a second or two. I have also noticed that Amazon Instant Video performs badly, especially in HD and to a much lesser extent when playing in SD. Netflix seems to play fine, as does Youtube in HTML5. I have the latest driver.

Yoga 2 Pro Brightness stuck at 100%
