How to do ctrl-break on Yoga 11s Ideapad - Break, Key, Keys, Keyboard, Pause, Windows 10, 2016

As there is no Break/Pause key on the keyboard ... What is the key stroke combo that allows you to do a ctrl-break?

 

I have searched around and cannot seem to find an answer.

 

I have tried all the variations that are listed on wikipedia

https://en.wikipedia.org/wiki/Break_key

 

I have also tried the other suggestions that are listed on this site, however they are for other products, and they do not work for the Yoga 11s Ideapad

Hi Warcop  , 

 

Welcome to the Community Forums. 

 

As those combinations you have tried aside from FN+Alt+B  / fn+Ctrl+P , if Onscreen keyboard and an external keyboard is not an option for you . It's worth a try to follow this guide specially item 5 (Add Functions You Don’t Have) remapping the key instead for the same purpose instead of using keyboard scan codes for registry changes. 

 

Due to the architecture for the yoga 11s maintaining its small size , some key features may have been omitted. 

As this is a probable work around , we hope that other members can also share ideas to such case. 

 

Update us how it goes.

 

Regards

Re: How to do ctrl-break on Yoga 11s Ideapad - Break, Key, Keys, Keyboard, Pause, Windows 10, 2016

Hi Spidey101 ... Thank you for the welcome and the suggestions.

 

  • Fn+Alt+B / Fn+Ctrl+P both do not perform a Ctrl-Break on the Yoga 11s Ideapad.
  • The default Windows 10 Onscreen keyboard does not have an on screen Break/Pause button.
  • An external keyboard - is just an ugly solution ... (why would a person buy a nice small portiable machine and then want to carry around an external keyboard?!?!)

 

I was hoping not to have to do a keyboard remapping as it can leads to loss of functionality if the Break/Pause key is re-assigned to another key that "might" be used in some other program. And that program could be from the OEM or from some other source. 

 

The OEM's have available keys that they can assign functionality to ... I believe windows key in combination with the numbers 1 through 7 are available to OEM...  Does Lenovo make use of all those?

 

So what key/keycombo is "truely" avaialbe???   ... or versley ... Whats the least used Function Key?  Would F10 be the best to remap for the "new" Ctrl/Pause button? Or would "Widnowsbutton #7" be better??? 

 

The guide you sent is good to perform the remap, if you want to load third party software.

 

Alternatively I found these articals on performing remap via the Registry.

 

Describies Creating the Registry Key 

Customize keyboard with Scancode map in Registry

Shows how to customize a keyboard in the registry.

Edit the registry at your own risk!

Navigate to the following registry key

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Keyboard Layout

Add a binary key and call it “Scancode map”.

Add 1 line of empty values:
00 00 00 00 00 00 00 00

The next part specifies the number of entries (set of 4 byte values or DWORD values). For each change you will add 1. You will then add a further 1 for the null value terminator. So for 1 change this value would be 2:

02 00 00 00

Now we change a key:

The first 2 bytes represent the new key, the second 2 the old key (so to speak). So for example lets make Scroll Lock output the ‘a’ key:

46 00 1E 00

Then add the null line terminator:

00 00 00 00

Our binary key now looks like this:

00 00 00 00 Version – all zero
00 00 00 00 Header – all zero
02 00 00 00 2 entries in the map, including the terminate
1E 00 46 00 a key (first 2 bytes) to Scroll lock (last 2 bytes)
00 00 00 00 Terminator

We can add more entries. Lets make Caps Lock output the b key

00 00 00 00 Version – all zero
00 00 00 00 Header – all zero
03 00 00 00 3 entries are now in the map, including the terminate
1E 00 46 00 a key (first 2 bytes) to Scroll lock (last 2 bytes)
30 00 3A 00 b key (first 2 bytes) to Caps lock (last 2 bytes)
00 00 00 00 Terminator

 

 

Shows the hex for ctrl/pause key to F10

*Changed the capitalization on Variable name from "Scancode Map" to "Scancode map" - Notice the M is no longer capitalized - I am not sure if capitilization matters but the above document show map in lower case ... and that is how I typed it - and that worked for me... after reboting ... Now pressing Fn+F10 will preform a Ctrl-Break on my machine.

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Keyboard Layout] "Scancode map"=hex:00,00,00,00,00,00,00,00,02,00,00,00,46,e0,44,00,00,00,00,00"

Hi Warcop , 

 

Tried to pull up documentation manual but does not give assigned shorcut for this model unlike other think machine. Don't have this model at the moment to test as same reason monitoring our post for others to share as there are designs that really don't have its break/ pause counterpart as with other manufacturers but no reason to give up. 

 

As for now , dificult to debug and code without it so provided workaround may help. 

I did not include the registry scan code solutions as i felt better in tested automated tools than changing registry (avoiding unintentional errors , better backup registry first ) .

 

Anyways those are choices for you , whichever would be convenient for now. Will update as soon as info is available. 

Update us too on your end . 

 

Regards

Sounds good ... would be nice for you guys to test out and give recommended button to assign the break key too.  If using the software you first suggest or the regedit method ... either way ... the recommended assignment would be appreciated.

I completed the regedit method ... I rebooted my machine ... I ran a long running program loop ... and I used the key combo Fn+F10 to break the program loop.

 

Still would be nice to know if F10 would be the best choice or if there is a better key/keycombo to use as the "new" Ctrl-Break key.
