Yoga 2 Pro: auto disabling keyboard in laptop mode bug

Hello.
I have a problem with my Yoga: very often (even if notebook placed on table) in laptop mode its disabling keyboard and touchpad on several seconds and then enabling it again. This enable/disble (flap) occurs time to time, most often after computer power on.
In this case work with mail or surfing web in laptop is not possible.
Someone have a hint how to repair it or how to enable keyboard manually permanently? Laptop is still on warranty, not broken, didn’t fall, win 8.1.
If need i can record some video on mobile phone with keyboard on/off.

Hi. Here it is. I tried to record the off/on process of this problem. On the seond part i typing in notepad and you can see interuption of letters.

Yoga 2 Pro No Virtual Keyboard in Tablet Mode?

I can't find a way to get a virtual keyboard to come up when Yoga 2 Pro is in tablet mode...even when I click on a search box in my browser or any other text box nothing comes up. Is there a way to make a touch keyboard come up so you can still type?
Many thanks!

Disable keyboard in sleep mode

My MacBookPro - wich is my second mac so far - unfortunately has a problem staying in sleep mode whilst being carryied. For me, this problem i quite serious since the otherwise fine sleep mode capability of Apple Mac's is one of the things that made me choose to 'switch'.
What I am experiencing is this; When I close the lid and make the MBP go to sleep and then moves it, a slight pressure to the lid makes the screen touch the keyboard - wich makes the MBP wake up.
Consequently I have had the MBP opened to try to adjust the keyboard ( Oooh - no warranty anymore ) but just discovered that the keyboard could not be adjusted. Looking at the keyboard at a very low angle reveals the sinner; the arrowkeys and right shift is about 1-1,5 mm higher than the rest of the keys.
So - I would like to know if it is possibly to disable the keyboard when the MBP is put to sleep.
Is there a hidden setting somewhere or maybe som 3. party software that will do the trick.
I really miss the rapid 'bootup' from sleepmode and the possibility to just close the lid and stow the computer away.
As things are right now Im booting up and shutting down about 10-15 times a day. It gives me a lot of time to drink coffee - but if that was my primary need whilst working with my computer I would be using a PC.

I know of no way to disable a USB keyboard while a Mac is asleep aside from disconnecting it.
Another approach is to make the keyboard unavailable with something like a keyboard tray that allows you to hide it under the desktop when not in use. Or one that lets you store it under the iMac.
But, the psychologist in me suggests a behavioral approach and teach the kittens to stay away from the computer. A squirt gun or spray bottle is a harmless way to teach them that this area is off limits. Squirt them and say NO firmly and quickly just saying NO will suffice. A few weeks of this and they should avoid the computer a together. Just do not spray your electronics!

Laptop mode tools problem with kernel 3.0

today I just updated the system and my laptop runs dramatically hotter after that. I read the archwiki, it does talk about the laptop mode tools problem with kernel 3.0 but when I opened the file /usr/sbin/laptop_mode, the lines which the wiki mentions are not there. Does anyone here have the same problem and can you offer the solution?
Here is my /usr/sbin/laptop_mode
#! /bin/sh
# Script to start or stop laptop_mode, and to control various settings of the
# kernel, hardware etc. that influence power consumption.
# This script is a part of Laptop Mode Tools. If you are running a supported
# power management daemon, this script will be automatically called on power
# state change.
# Configure laptop mode tools in /etc/laptop-mode/laptop-mode.conf, and in
# the broken-out config files in /etc/laptop-mode/conf.d.
# Please consult the manual pages laptop-mode.conf(8) and laptop_mode(8) for
# additional information.

# This is a 2 phase locking approach. LMT_REQ_LOCK is the outer lock and LMT_INVOC_LOCK is the inner lock
# We take this approach to ensure the scenario that, "At any point when an event occurs (AC/BATT), the
# kernel can generate multiple events spanning over a couple of events. The first event is honored and
# lmt executes. If the last event triggered at the 9th second, there is a fair chance that a good amount
# of state change would have occured in the OS, to honor that state, we keep an outer lock (LMT_REQ_LOCK)
# handy, so that those changes can also be applied and not forgotten.
# Workflow:
# Event-1 is generated and lmt executes (lmt runtime could span 5-10 seconds)
# At seventh second, 4 events generate. But Event-1 is still running.
# We don't want to discard all the remaining 4 events, but at least honor 1 so that we can act to the changes
# that occured in the last 7 seconds.
# So, Event-2 acquire LMT_REQ_LOCK and waits to acquire LMT_INVOC_LOCK (which is acquire by Event-1)

I had the problem but edited the line in /usr/sbin/laptop_mode and it worked. But thoes lines are not there anymore. I guess they changed it at the recent update of laptop-mode-tools.
Regarding your heat problem; is there any other thing you use to cut down power usage (from AUR maybe)? I use acpi_call from AUR had to edit lines there aswell, but it should be updated by now.

Keep Yoga 3 Pro in Laptop Mode

I connect my Yoga 3 Pro to a Lenovo USB dock and display to a large monitor at my office desk.
When I close the lid, my Yoga changes from Laptop Mode to Tablet Mode. I would like to keep it in Laptop Mode when the lid is closed at work, so that I can display some programs in larger font -- in Tablet Mode on my external monitor, QuickBooks is unreadable.
Is there a setting I can change so that, when I connect to my external display, I can close the lid and keep my Yoga in Laptop Mode during that session?
Thanks!

I'd try disabling the ymc service.
Try stopping it in Task Manager -> Services
I'm running without it, since my accelerometer is shot and makes the Yoga think it's in tablet mode all the time, and it seems to keep it in laptop mode all the time.

Yoga 2 Pro display/screen wobble in laptop or stand mode

Been looking around but can't find anyone mentioning the screen/display wobble when using the yoga 2 pro in laptop or stand mode. That baffles me. I tried normal touching on the screen on the Yoga 2 Pro at Best Buy in laptop and stand modes and the display bounces back and forth horribly. I can't believe this wouldn't be a deal breaker for many people unless most people just aren't using the touch screen (in those modes) that much. And if they aren't, what's the point of having the touch screen (other than tablet mode). Windows 8 is meant to be used with a touch screen in ANY mode.
So, can anyone comment on their experiences with a wobbling/bouncing screen/display?

Hmmm. Wonder if you've actually used the Yoga 2 Pro. Or maybe you're trying a little too hard to defend your expensive purchase. Either way, calm down, buddy. This system seems nice, just not for me with that wobble when *BARELY* touching the screen. The Surface Pro 2 solves the issue with a backstand. The Samsung Ativ series doesn't seem to have this issue. And, yes, both of those are comparable systems.
I actually searched a little longer and DID find others complaining about it on the Yoga 2 Pro. It may not be a dealbreaker for you, but it is for some. Its irrelevant if it "comes with the territory...for this form factor" if it distracts *enough* from its usefulness (and thats putting it nicely).

Yoga 2 Pro - Black screen when on tablet mode

Hi,
2 weeks Yoya 2 pro out of the box, and get a black screen when reaching the tablet mode (back of the lid touching the back of the laptop base).
I try hanged the setting under power management, with no success. When reaching the tablet mode, I get the same result as closing the lid in laptop mode.
I connect my Yoga 2 to a TV through the HDMI and can see the screen and interact with the black screen (not easy to touch the right spot).
My bios is updated and I have Windows 8.1.
Any suggestion???

I found the answer to my problem at
http://forums.lenovo.com/t5/Idea-Windows-based-Tablets-and/Yoga-2-Bios-Update-Crash/m-p/1322487/high...
Now that I found that post I do recall the instructions telling me to turn it off manually when I updated the bios earlier this year. However, the current instructions do not mention it at all, perhaps they should be updated?

Yoga 2-11 Onscreen Keyboard won't stay up when in tablet mode

I have seen many topics about the onscreen keyboard not staying on when in tablet mode but most of it from 2013. I am having this problem and I cannot find a solution. I have to go to laptop mode to sign in and then go back to tablet mode. The keyboard pops up but as soon as it does it goes away. What is the fix? Yoga 2-11 purchased Dec 2014 from Best Buy.

Thank you for your swift suggestion! I think it has worked I will monitor it for a couple of days

Laptop mode tools shut off keyboard

When I have the laptop mode tools daemon enabled in rc.conf, the keyboard will stop functioning if a) I'm in the console and b) I leave the keyboard alone for ~10 seconds. There's no freeze, because the cursor is actually still blinking, and if I keep typing it doesn't shut off. I assume this is the LMT disabling my keyboard after some degree of inactivity-- of course, I can't get back after this, because the mouse doesn't function in console and the keyboard can't reactivate itself. I don't see anything relating to the keyboard in the config, is this a bug?
I have a Macbook 6.1, by the way... I'm not sure if the Mac's keyboard is any different from another laptop's in how it transmits data.
EDIT: If I start X, then go back to the console, this still happens, but it gives a message this time:
PCI_PM_runtime_suspend():hcd_pci_runtime_suspend +0x0/0x20 [USBCore] returns -16
I think this is indeed LMT shutting off USB support when it's not in use-- but on the Macbook, the keyboard needs that function. 'options usbcore autosuspend=0' in modprobe.conf does not fix this, so I'm stuck at this point...
Last edited by DrKillPatient (2011-08-31 13:18:23)

Did you try turning off USB suspend in LMT itself?
in /etc/laptop-mode/conf.d/usb-autosuspend.conf:
CONTROL_USB_AUTOSUSPEND=0

Laptop mode tools disables bluetooth.

I have a weird issue with laptop mode tools, when i boot up on battery bluetooth is disabled until i plug in a power supply. After its enabled i can unplug it and bluetooth will work.
Bluetooth control is disabled in bluetooth.conf. I tried switching off usb-autosuspend but that didn't help. The only thing that helped was turning off auto modules in laptop-mode.conf and enabling only cpufreq. I tried enabling everything by hand but the problem came back so it seems like some module other than usb-autosuspend or the bluetooth module is the problem.

Laptop Mode Tools is configured to set my SATA link power management to "min_power". Essentially, it does
# echo "min_power" > /sys/class/scsi_host/host0/link_power_management_policy
when I unplug, and
# echo "max_performance" > /sys/class/scsi_host/host0/link_power_management_policy
when I plug in the laptop. I can check the value with

Setting max_performance when plugging works great. Unfortunately, when I unplug, it stays stuck at max_performance. Restarting the LMT daemon fixes this temporarily, until I unplug again.
Is this a bug? Or am I missing something? I'm on a Dell Inspiron 7520, about 3 months old, and so far, Arch doesn't seem to like the more esoteric features of the laptop, like the switchable graphics card.
Thanks for any help!
Have you searched the all-powerful google or the Arch wiki, friend?
Oh, and welcome to Arch Linux since this appears to be your first post! Hope that you like it here and enjoy your stay!
Also, I don't know anything about the Laptop Mode Tools, since I don't use them even though I have a laptop, perhaps I should take a look into them for my own benefit as well.

Trouble with Adobe Reader Touch on Lenovo Yoga Pro 2 in tablet mode. Pdf shows up as blank pages.

I have a Lenovo Yoga Pro 2 and when I change it to tablet mode and use the Adobe Reader Touch app, my pdf shows up as a blank page. I have installed other pdfs in the past and those show up fine. However, as of three days ago, whatever pdf I install shows up as blank on my screen. Is there a solution to fix this?

Could you please share your test file?

Yoga 2 Pro -- how to turn off switching mode notifications -- e.g. "tent mode", "tablet mode", etc?

Does anyone know how to turn off the notifications that pop up in the upper right corner telling you that you have just changed from one configuration to another -- e.g. changing from tent mode to tablet mode?
Solved!
Go to Solution.

Just disable it -
Task manager > Startup > Click "Yoga Picks" > Click "disable"
Next time you start your computer no more annoying pop ups. If you want to be annoyed again you can always re-enable it.

[SOLVED] Temporarely enable/disable laptop-mode-tools while on AC?

There's an option in laptop-mode.conf for it to run on AC by default
# Enable laptop mode when on battery power.
ENABLE_LAPTOP_MODE_ON_BATTERY=1
# Enable laptop mode when on AC power.
ENABLE_LAPTOP_MODE_ON_AC=0
I'd like to keep it off on AC like it is by default, there's just scenarios where I'd like my laptop to run especially quiet, even if plugged in (eg. gf sleeping)
Is there a command to turn it on/off on demand?

"laptop_mode stop/start/auto", I'd say.

Problem heat macbook pro on AC laptop-mode

Hi,
i m confuse, I dont understand why on AC the top left part of my Macbook pro is getting hot.
xsensors show my CPu around 65 under AC
on BAT my cpu are very cool and my laptop too. ְ This is how I want it all the time !
I have laptop-mode-tools installed I change th config file to use also laptop mode on AC but i dont know why it is still heating more than on Battery.
I adjusted laptop-mode/conf.d/wireless to be powersave even on AC with latop-mode.
cpupower shows on AC or BAt powersave, i switched off the bluetooth on AC, But i still heating up on AC
Someone can tell me where to look ?
It fixed it just when the battery is charging btw 30 percent and 80 percent that is getting hot
