There's NO "on screen tab" in Advanced Settings tab

Does this apply to Windows 8?

I have the same problem. There's no on screen tab in Advanced Settings.

Please answer this. Windows 8 do not have on screen tab

Answer the question!

I had to change the harddick in my Lenovo G40-70. Now the computer does not access the SD card slot containing recovery media. "no bootable device". Only option given by Boot Manager is EFI Network 0 for IPv4, which is not successful. How can I re-install from SD slot?

"there's NO "on screen tab" in Advanced Settings tab"
What can we do in this case?

Here's a solution that worked for my new Y50.
0. Restart your computer, and after you get to the Desktop, keep tapping the Caps Lock button. See if you get a pop-up allowing you to turn the notification off. If you don't get the pop-up, go to step 1.
1. Windows Key + R
2. Type "regedit" and hit Enter
3. Click Yes
4. Navigate to HKEY_CURRENT_USER/Software/Lenovo/Energy Manager.
5. Double-click on NotShowMsgAgain.
6. Change the value to "00 00 00 00".
7. Click Ok, then restart.
8. Tap Caps Lock repeatedly after you get to the desktop, and the pop-up should appear, letting you choose "No Thanks".
You should no longer have to deal with this annoying problem!

I have the same issue with my Flex 3. But i can't find the NotShowMsgAgain under energy manager. Is it called differently?

If you follow what Michael instructed, and get to #5 and can't find that line, look for "enable OSD" and change that one to 0s.

My lenovo G50 that has Windows 10 and doesn't have Energy Manager under Lenovo at step 4
the options are as follows

Is it in one of these files or in a different place for newer laptops?

Same, I don't have Energy Manager:/

I report the same: no energy manager on Lenovo Z51-70 with windows 10.
No "Widdcom" entry in registry either.
No "On-Screen Display" in either advanced display settings or "Display adapter properties".
I have not yet found a solution to this problem.

Found solution:
I disabled "LenovoUtility.exe" in task manager, and then prevented it from running on startup (to do this, navigate to the "Startup" tab in task manager and disable it).
I don't know what else Lenovo Utility is used for, so disable it at your own risk.

STOPPING CAPS LOCK NOTIFICATION: For Lenovo laptops with Windows 10, energy manager is already in Lenovo Vantage, so that is the only app you need. You can fully uninstall the Lenovo Utility and then the message will no longer be there. As for the conservation mode, it is within the Vantage app. Look for battery settings. SWITCHING BETWEEN POWER PLANS: It is frustrating now to change the power plans, but if you want to learn to do so, right click the battery notification and go to power settings. If there is no High Power mode, you can set up a High Performance mode in there by yourself. When you switch to Balanced mode, clicking on the battery icon allows to move the slider only to the Performance mode or ECO mode, but if Performance mode is selected, then the Balanced mode can be activated only by going into the Power Options and choosing Balanced mode there. Weird and annoying, but that's how it works now in Windows 10. Make sure to double check the power plan choice before using computer for intensive tasks because Energy Manager worked better than the Windows Power Options do in Windows 10. After a full and clean upgrade from Windows 8.1 to Windows 10, the power plan sometimes does not change even after attempting to do so. Try two or three times and it will change. Since I play games a lot, I choose to use Performance mode for everything. It is way too easy to forget to change the power plan. So, be careful not to damage your computer!

Truenotebook, thank you for ruining the comment with your formatting preferences. Now it is barely readable.

(WINDOWS POWER OPTIONS) ECO MODE WARNING: Be careful not to harm computer components by choosing an ECO mode for all tasks and then making it to do extensive and demanding tasks with little power because computers need a specific amount of power to perform specific tasks. If tasks are requiring more power then an ECO mode is set to supply or there is barely enough of power to keep on running, that is causing a quicker ageing of computers. For a light and careful user an ECO mode can be enough, but an average user needs to choose a Balanced mode for general use and Performance mode for intensive tasks. Performance mode is for those users who run intensive programs or play high-end games a lot of the time. VR and 4K contents often, but not always, require high or highest power mode. Switching between the power modes can be forgotten or the purpose misunderstood. So, take your time to understand them correctly and choose the one which suits the purpose.
