Another Lenovo Y460 user reporting in. Have been using it for almost 2 weeks.

There's a bit of a catch to the OKR (One key recovery) system in that it will only work if you did not change the partition size of your boot drive (by default the C drive). If you do then the OKR is useless. You can delete all Lenovo pre-installed software and the OKR will still work. But if you recover your system this way then it will return the system to factory default together will all the junks in it.

A better way will be to install the OKR software and use it to backup the system in the current state (ie. after all those junks have been removed) and use the DVDs created to recover your system. Hope this helps

My apologies for taking so long to reply,

As far as I have tested out you can reinstall windows without messing around with C Drive's size and OKR will still works. To make OKR work again if you've resize C Drive (assuming you've left the hidden partition as well as the D drive intact) then remove all the partitions you make on C and OKR should work again.

If all else fail, then you'll probably need to use another method of creating your system image for backup purposes.

If I'm not mistaken both mutesync.exe and audiodg.exe are used by the touch control buttons for the audio control on the laptop. Remove or disable them and the buttons will fail to function. Note that mutesync is only provided on the drivers in the D drive and cannot be downloaded from Lenovo's support page.

Yes, you can. Insert your own win CD/DVD and select custom installation and select the C drive as the installation partition instead of selecting the upgrade option. If you do it this way your previous installation files is assessable via a folder called Windows.old (you can access the files only but you cannot boot into your previous OS).

Note: You can also choose to format C and install your new OS there. Either way OKR should still remain functional. Please be aware that if you restore your system using OKR it's still going to return to factory default.

Funny, I don't have onetouch support.exe but I do have OnekeySupport.exe. I also have mutesynce.exe but not audiodg.exe. (Note my version of OS is a self installed version and not the one from Levono's factory default).

No, the hidden partition is another partition by itself and drive D contains the backup drivers. Your C Drive (the largest partition) is where the OS is installed. Actually Lenovo power management only works for the power management function (you can remove it and use win 7's default power settings and the rest of the touch controls should still work). The OneKey Theater II, mute and audio touch controls have their own drivers.

The only reason why that would be the case would be if these drivers share some common files but I've not tested that out before.



Yes, as long as you don't resize your c drive it will work.



Yes, it must be back to it's original size for OKR to work and do note that you'll need the hidden partition intact as well.



OKR will cause an error (it might hang while attempting to restore to factory default or from another backup source) when you attempt to use it after you've resize your C drive

Hope this helps clear up the confusion about OKR

Install this: Lenovo SlideNav (File name: IN8STW01WW6.exe).

Note: You cannot find it in Drive D but you can download it from Lenovo's support website.

After installing (it's actually only copying the files to c:\Drivers) go to c:\Drivers\Lenovo SlideNav\Installation and run Installation.exe Then go to c:\Drivers\Lenovo SlideNav\x64 and run SlidebarConfig.exe.

If all goes well you should be able to use the slidenav again.

Hope this helps

In actual fact it will affect the function of the OKR (One Key Recovery). It is a known problem across multiple Lenovo notebooks that OKR will only function if the size of your system partition (drive C) remains intact.

If you resize it then OKR will not work and you'll have one useless button on your notebook. There's a whole topic on OKR and partitions on the official Lenovo forums if you're interested to read more about it.
