***Yoga 2 Pro Owners Thread***

My color profile makes a very subtle change to the default Y2P color space.

The only thing I can think of is that your machine has a modified color profile via some other means, such as the Intel color correction tools and that interferes with my profile.

The Yoga 2 Pro only had the Samsung panel with the Yoga Yellow issue.

Also, make sure that you are using the latest version. This is for the latest version of the Lenovo energy manager.

Ping me privately if you still have questions.

 

Thanks, I actually did use the older one posted back on page 178, now I used the updated one for the .51 Energy Manager. To me, switching from f.e. the standard sRGB or Adobe RGB 1998 to your profile does not seem "subtle", I can see a noticeable difference in the whites immediately. I dont know, maybe the display takes a second or my eyes get used to it...starts to look normal after a short while. No way to demonstrate that here.

I haven't touched any of the Intel Color Settings in the driver Settings. Driver version is 20.19.15.4474.

If there is a way to message you privately, I'd be glad to, but couldn't find it so far.

 

@DudeFromKalispell

You don't want to use sRGB or Adobe RGB in your color profiles... remove all and use no profile or my own profile.

I started a conversation with you, in case you needed.

 

HI All,

I have a Y2P that is a couple of years old. I upgraded to w10 a few months ago and have noticed several issues (not sure if it is related). I would appreciate any advice:

• When I close the lid (not shutdown) and open it back up the computer seems to lag when waking back up. Sometimes it becomes very laggy and I have to restart
• Screen: Occasionally I will get a flicker, it goes completely black for about 1-2 seconds, and then comes back on. Doesn't seem to be any problems after that.
• Mouse: Changes speed when closing and opening lid. I do not use an external mouse.
• I'm running f.lux and Classic Shell. Never had any issues with them before W10

I've only updated drivers when upgrading to W10, probably done though Microsoft. I'm not really computer savvy so may need a little more explanation if I have to update drivers or look at anything else.

I really appreciate any advice!

 

For screen flicker, right click on the desktop and click Graphics Properties to open Intel Graphics Control Panel -- inside, click Power, then On Battery in the menu on the left (you're probably seeing what you describe only on battery power)

In the options shown, disable Display Power Saving Technology.. AND/OR Panel Self-Refresh. I say and/or, because I'm not really certain which does the trick.. I remember in the past ending up disabling both, and that did it, as I had trouble determining which it was. They get re-enabled when the driver is updated (just happened to me the other day), so I'm currently trying with just DPST disabled, will see if that does it. I believe Panel Self-Refresh yields a fair bit of battery savings, so seems better to leave on if it works ok with it (but I base that on not much direct knowledge). Anyway, I'm pretty sure that between the two, it solves the problem -- if anyone can confirm which one is the culprit, by all means chime in.

Re f.lux, I'm running it, haven't had any problems.. is it not working?

 

To follow up on the above, it seems to be Panel Self-Refresh that is the culprit for that (i.e. the occasional random screen flickering to black for a number of seconds).. having said that, I was reminded that Display Power Saving Technology is also responsible for screen brightness adjusting in rather schizophrenic fashion, hence why I had had that disabled also. Battery impact aside, I have the most consistent screen experience with both of those disabled.

 

Thanks, gilgamesh0 for the response. I made the suggested changes, so we'll see what happens. I do believe the ficker always happened on battery, as you mentioned. I'm not having any problems with f.lux, just wanted to mention other programs I have running to rule out any issues.

The mouse issue is driving me bonkers but something I can live with.

 

That's interesting, I can't recall seeing speed changes with the mouse. I use a USB mouse (Intellimouse) frequently at home, and an MS Bluetooth mouse occasionally when away -- the top speed is slower than I'd like (I've got it maxed out in settings), but I don't think it ever changes.

 

Hey guys, I signed up for this forum out of sheer desperation. I bought my Lenovo Yoga 2 Pro January 2015. I absolutely love it except for the fact that it's not the sturdiest device. I've had to send it in three times during my warranty. Once for a defective audio jack 2 months in, once for all the screws popping out the back, and the third time due to the back cover literally popping off on one corner with my wifi card and USB port damaged as a result (No, I do not abuse my device. It has never been dropped and I carry it in a laptop case). Now, my warranty has been over for a couple of months and my audio jack started acting up again today. It was working just fine yesterday and now, I can only play sound out of my speakers. The laptop doesn't even recognize the earphones that I put into the jack. No pop-up notice about an audio device. Just doesn't even recognize that it's there. I've restarted, tried the mute/unmute thing, redownloaded the audio drivers and it's still not working. I know the earphones are fine because they work on my phone and tablet. I have a horrible feeling it's a hardware problem, but again, my warranty is already over. So three questions:
1.) What have I not tried so far that I can still try?
2.) Let's say this is a hardware problem. How much would it cost to get this fixed?
3.) Let's say the fix is out of budget. Is there some substitution for the audio jack? When my wifi card stopped working, I had a Wifi adapter that I used through a USB port. Is that possible for audio?
Thanks.

 

1. Try uninstalling the audio driver, rebooting and then reinstalling it. I've seen situations where the driver configuration gets screwed up and this "may" fix it.

2. For a hardware option (external), you can get a Digital to Analog audio hardware device that uses (and is powered by the...) USB port. I use one for my larger setup and works very well (Micca Origen+ DAC, but there are cheaper options as well).

3. The headphone connector can probably be replaced, but you'd need a Lenovo part number to have it done correctly.

Hope this helps... and keep those screws tight

 

I've actually already tried the first. When I downloaded and installed the audio driver from the Lenovo website, it automatically uninstalled the existing driver before installing the one I had downloaded. It then restarted upon completion of the installation. No luck. I don't know what could have happened to make it a hardware problem. As I've mentioned, I keep my laptop in good condition. It was sitting on my desk overnight, so I have no idea what occurred in the meantime.

 

Does Windows detect the insertion of the headphone plug?

Did you then check the volume levels (independent from speaker volume)?

 

No, Windows doesn't even detect the insertion of the headphone plug.

 

I still suspect the driver... is THIS the driver?

Some users have had luck by repeatedly (30x or more) connecting and removing the plug, or by squeezing/tapping the area above or below the headphone jack.

 

After looking at the costs to buy a new Ultrabook I decided to refresh my Y2P. I picked up a Samsung Evo 850 500GB SSD on Amazon for $165 to upgrade my stock 256GB SSD. I wanted to do the 1TB but at $352 I didn't need that much storage.


I also finally got the Wireless AC card : https://www.amazon.com/gp/product/B00GUNZUG0/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1

The wireless card install was a breeze and my wifi connection is rock solid. I am not sure why I waited this long to do that.

The SSD drive upgrade was a little more cumbersome. I used this thread as a guide. https://forums.lenovo.com/t5/Lenovo...pgrading-the-SSD-in-a-Yoga-2-Pro/td-p/1389081

I ended up having issues with partitioning the new drive and I wasn't sure how to get the unallocated space into the C: drive. So, I decided to download a fresh copy of Windows 8.1 from the MS site. https://www.microsoft.com/en-us/software-download/windows8 It turns out the software Key is embedded in the Y2P so no issue there.

With a fresh copy of 8.1 there is no bloatware. I was able to download all the drivers from Lenovo and everything works.

I did do a benchmarck on the old SSD verses new SSD and it is quite a bit faster. Before the upgrade and windows reinstall I couldn't play 4k video without it being choppy. It is smooth as butter now So, all in all it was worth it....I will get a few more years out of this thing



One pro tip on pulling the connector of the batterey free for the SSD and Wifi Card upgrade...use your fingers and not metal tweasers.

The one issue is that I can no longer log into my old Microsoft account with Windows. I spent 3 hours with Microsoft Support...they took control of my laptop and couldn't fix it. So, my Onedrive days are over but I switched to Amazon Prime Photo storage.

 

Well, I discovered an issue. The battery consumption is out of control :/

Airplane mode, dimmed display, the CPU is hovering around 1 - 3 % at .76 ghz and I am seeing around 9,000 mW up to about 13,000 in the lowest power setting on Energy Manager. I used to see around 5,100 mW to 7,000 mW in this configuration. Ideas?

 

I've been seeing a new problem with the yellow color fix and EM since upgrading to Windows 10 last year (I think that's when it started, have waited for a while to investigate).

Basically the yellow fix in general continues to work as before with the latest energy manager and bios -- however what I'm finding is that periodically it just "goes away", basically the colors revert to how they are without the fix applied.. similar to how it looks when you first boot up, before energy manager starts up and the color correction kicks in.

Whenever this happens, I can remedy it fairly quickly within energy manager, by selecting a different mode (say Cinema) and then selecting Daily Mode (which I normally run in) again, and the colors come back to normal.

It's a pain to have to regularly do this though. It may be that this is being triggered when the screen dims due to inactivity, seems that way offhand, but I haven't been tracking it carefully (since usually I'm not paying attention at such moments by definition ). Adaptive brightness (or what seems to be the equivalent in win10) is not enabled.

Is anyone else seeing this behavior? Any known remedy? Thanks.

 

Hi Everyone,

Over the last few weeks I realized the driver for the laptop camera was gone, and there was just nothing under the driver manager. I went on the lenovo site, and downloaded one of the camera drivers, which seemed to work for a day, but today when I tried to skype with someone, the light turns on (which it didn't before) but no image shows up in Skype or with the camera app. Does anyone have any ideas?

https://pcsupport.lenovo.com/us/en/...books/yoga-series/yoga-2-pro-lenovo/downloads

I tried both the Bison and Liteon drivers, but neither of them seems to work. The Bison worked a few weeks ago, but not now. Am I using the wrong driver, or is it possible my camera has just physically died, and there is nothing I can do about it? My hope is that its just a software issue, as that's what seemed to be the issue originally, but now I'm not so sure. I rarely use my camera, and usually keep it covered with a sticker (yes I'm paranoid), but I think there might be a chance that the Fall Creators Update messed it up, but I don't use the camera enough to know for sure. Would appreciate any thoughts.
