Disable "sleep" shortcut on backspace key on Thinkpad P73

I have a Lenovo Thinkpad P73 running Windows 10. The backspace key above the number pad doubles, for some reason, as a sleep shortcut key:

I use the number pad a lot and regularly hit this key by accident, and it's extremely irritating (like, HR-complains-about-my-language-at-work level irritating).

Is there a way to disable the sleep shortcut on this key? I didn't find any settings in Lenovo Vantage or in the keyboard control panel, and I'm having trouble doing an internet search because of how generic the words are.

One of the strange things about this key is its functionality is reversed compared to the F? keys and their shortcuts. By default, with Fn Lock off, the F? keys do shortcuts (volume and such) but the backspace functions as backspace, while with Fn Lock on, the F? keys are the F keys but the backspace is sleep.

Since I use the F? keys regularly I keep Fn Lock on, so while I know turning Fn Lock off at least requires me to press Fn with backspace to sleep, I keep Fn Lock on almost all the time, so that's not a solution. However, I would accept a solution that just swaps the functionality (Fn Lock on requires Fn+backspace to sleep) as an alternative to disabling it.

If I can't find a software configuration solution, the fallback plan is to just physically remove the key, since I don't really need it. But I'd rather not do that, for various reasons.

Solution 1:

One solution would be to. . .

1. Go in "Power & Sleep" settings
2. Then "Additional power settings"
3. Select "Choose what the power buttons do"
4. Select "When I press the sleep button: Do nothing"

Solution 2:

In addition to the solution by Ben, there is another location that you might want to check if something doesn't work as expected. The setting above is for all power plans, but apparently the plan itself can still override.

In the Power Options overview click on "Change Plan Settings" and then "Change advanced power settings". Scroll down to "Power buttons and lid" and set the Sleep button action to "Do Nothing". Note that this does not affect the general setting except if the plan you're editing is the "recommended" plan.

In my case the general setting was set for the PC to go to sleep when pressing the sleep button, but in the details of the currently used power plan it was set to "do nothing", so for this power plan, nothing happened when pressing the button.

Solution 3:

You can reverse the FnLock key so if it's on, you have the special functions and if off you use the Fn-keys. But the keys above the number pad aren't reversed! So if the FnLock is off, you have the Fn-keys and the '=' and Backspace.

The option is in Lenovo Vantage settings at Devices > Input ...
