Hey guys!
So I notice a lot of these questions get asked a lot, so I figured I would just cover them here, since there doesn't seem to be an aggregated thread for this kind of stuff:
Q. My yellow is really gross looking.
Update to the latest BIOS as well as the latest version of Energy Manager. You can find them here:
BIOS: http://download.lenovo.com/consumer/mobiles/76cn31ww.exe
Energy Manager: http://download.lenovo.com/consumer/mobiles/em10149.exe
Q. My yellows are still off.
Double check that you installed the latest BIOS and Energy Manager again. Then make sure you're not in stable mode, it makes the yellows look bad.
If you've done all of that, maybe the yellows just don't look good to you.
Here's what the Chrome Icon looks like with and without the fix (yours could look worse):
(Disclaimer, these are photos taken with my Nexus 5)
Notice that without the fix, yellows essentially look brownish/mustardish.
Q. I want to upgrade my wireless card, but I can't figure out which one to buy.
The Yoga 2 Pro uses the newer M.2/NGFF standard for its wireless card, instead of the older, mSATA, so a lot of wireless cards aren't going to work.
Since both form factors are conveniently named the Intel 7260, it makes life a bit confusing.
What you want is one that looks like this (M.2):
Not this:
Personally, I got mine from M|Factors Storage, but I am in no way endorsing the company.
For information on how to install a new Wireless card, please consult the Service Manual: http://download.lenovo.com/consumer/mobiles_pub/lenovo_yoga_2_pro_hmm.pdf
Q. What about a bigger SSD?
The SSD on the Yoga 2 Pro is a standard full-size mSATA SSD, so any mSATA SSD will do. Please refer to the Service Manual for disassembly instructions.
Q. My screen keeps changing brightness/flickering. Make it stop.
There are two things that could cause this: Intel's Display Power Saving Technology, and Windows Auto-brightness.
These are two very different beasts:
Auto-brightness adjusts the backlight of your laptop display based on the ambient light conditions. This happens based on the readings from a sensor located to the right of your webcam. In darker environments, the display will automatically dim, while in brighter environment, the display will automatically brighten. To test this out, simply turn on the feature and press your thumb over the area roughly half an inch to the right of your webcam; after a few seconds, the screen should dim. Note that this does not override your manual brightness, but rather works around it. If you manually turn up your brightness, it's roughly equivalent to saying you want your screen to be brighter in all situations.
Display Power Saving Technology adjusts the backlight of your laptop display based on the content being displayed on the screen. A white image will cause the backlight to brighten, whereas a dark image will cause the backlight to dim. This will happen even if you are sitting still in an evenly-lit environment.
If you guys have any questions you want me to cover here, leave a reply, or send me a PM; I'd be happy to include your questions.
To turn off Auto-brightness: Go to Power Options > Change Plan Settings (on the plan you want to turn off auto-brightness for) > Change Advanced Power Settings > Display > Enabled Adaptive Brightness > Off
To turn off Display Power Saving Technology: Go to Intel Graphics Control Panel > Power > On Battery > Intel Display Power Saving Technology > Off
Turning off both of these features significantly reduces flickering, although some users still claim it happens on low brightnesses.
I hate the two-finger scrolling. It's backwards.
There are two ways to reverse the direction of the scrolling. I prefer the second.
The first is very straightforward. Simply install the touchpad drivers from the original Lenovo Yoga 13 from here: http://download.lenovo.com/consumer/mobiles/0ttp18ww.exe
And then there should be an option in your Synaptics Control Panel (under Control Panel > Mouse) to reverse the scrolling direction.
The second method is to use the Yoga 2 Pro drivers and simply make a small registry change:
Go to:
HKEY_LOCAL_MACHINE\SOFTWARE\Synaptics\SynTPCpl\Controls\2MultiFinger\NestedPropertySheet\1TwoFingers\ReverseScrollCheckBox
And change Visibility from 4 to 0.
Alternatively, the key may be called "Transparent", in which case you should change it from 1 to 0.
Similarly, the reverse scrolling direction option should appear in your Synaptics Control Panel.
Using this and similar registry tricks, it's also possible to enable a bunch of other options, but I won't cover them all here, since I don't remember them right now. PM me if you want more information.
I get a humming/buzzing/static noise through my headphones plugged into the 3.5mm jack
Unfortunately, there's not a really good fix for this one. If you have very sensitive headphones, then they're going to pick up a lot of static since the audio output of the Yoga 2 Pro is pretty dirty. I definitely have found that uninstalling the Realtek drivers and using the Windows one significantly improves the noise, but once again, if you have sensitive headphones, you'll still pick up noise. Also, the Realtek drivers significantly improve the volume of the speakers, so I opted to keep them installed.
Outside of buying an expensive external DAC (which is the real solution), the best solution I've found is to use an inline impedance adapter like this one:
http://www.monoprice.com/Product?c_id=108&cp_id=10823&cs_id=1082703&p_id=7116&seq=1&format=2
Basically, this will reduce the volume of everything coming out of the jack. Since I normally have my volume at around ~20/100 when I use headphones anyways, I just turned down the volume control using the analog knob, and cranked the digital volume up to 100. This significantly (read: eliminated) the background static even with the Realtek drivers installed, and only cost me about $3.
My laptop is too loud. I want to make the fans quieter
The general recommendation on this forum appears to be to use NotebookFanControl 1.0.0.0 (or newer) to control your fans.
You can download it here: [Vorstellung] NoteBook FanControl (NBFC) - ComputerBase Forum
The process is very simple. Just install the program, start it up, and choose the correct laptop and it should start working immediately.
Personally, I had an issue where running this program at startup caused features such as gesture-based passwords to take a long time to execute/start up.
Alternatively, you can use TCFP, which you can get here: TPFanControl by troubadix
Make sure you download the correct version for the Yoga 2 Pro.
It operates similarly to NotebookFanControl, but lacks a few options such as Hysteresis, but it doesn't cause any startup lag, so it's what I've been using.
You can manually edit the behavior of either program, but you have to be willing to work through some config files, which you'll have to figure out yourself. I've attached my personal settings for TCFP here (it's quieter, but runs hotter than the default config file): https://mega.co.nz/#!jY92HQzJ!YsxlhBGNHVYGgxQ9Tb38C1ZTrLpChAGKehgjeVVJ-0c
To use it, just replace the file with the same name under your unzipped folder.
What is undervolting? Is it safe? Should I do it?
Undervolting refers to forcing a chip to run on less voltage than it's spec says. Generally, more voltage = more stability (I won't get into the details, but if you want more information on timing, I'm a computer engineer, PM me) so undervolting your machine can cause stability issues. However, these issues are generally not permanent and will be fixed when your laptop reboot with the stock voltages. Very very rarely will this cause permanent damage, but I take no responsibility if it does. Why would you want to undervolt? Because it saves power. I don't have the exact numbers to prove it, but at least theoretically it should.
To undervolt your laptop, download the latest version of Intel Extreme Tuning Utility from here: Intel® Extreme Tuning Utility (Intel® XTU)
Once you've installed it and rebooted, open it up, and go to the "All Controls" tab. What you'll want to focus on are the "Processor Cache Voltage Offset," "Dynamic CPU Voltage Offset," and "Processor Graphics Voltage Offset." If you don't know what you're doing, you should probably leave the other controls alone. These values can be tuned in order to "undervolt" your laptop (make sure you hit Apply afterwards). The more negative the values, the more you have undervolted your laptop, the less power you will consume. Generally, I would say -50mV is safe for all of the controls, but it varies from laptop to laptop. My controls are set to -70.31, -64.45 and -80.08. To find out your maximum undervolt, you just have to play around with the controls and figure out how low you can go without your laptop crashing.
If you guys have any more questions you want listed here, please feel free to reply, or PM me! I'm open to suggestions.
