Thinkpads Forum

New w510, I continue to run into little stumbling blocks.

In order to save space on my SSD, I've disabled auto-hibernation and deleted hiberfil.sys (was taking up a pointless 10GB)

but I was curious what would happen if I accidentally press fn+12. Result: the computer still hibernates, and re-creates that annoying hiberfil.sys.

is there a way to remap or disable the fn+f12 command? I've been digging and haven't found much.

Thanks!

It's extremely difficult to accidentally hit Fn/F12.
Just don't DO it.

I've done those things.

Even after disabling hibernation, if you hit fn+f12, it gets re-enabled and the hiberfil.sys gets recreated.

I'm not so worried about doing it myself, but someone else using the computer, or a cat on the keyboard...

I don't want it to even be possible. is there no way to reassign fn +* keys?

I saw a thread on another forum with links to a series of unsupported bios flashes for different models that have the effect of swapping the Fn and Ctrl keys. Don't have a clue though as to whether it might be possible to go the extra step and change or disable a specific key combination. If this sounds at all promising, follow the link in the first footnote at
http://en.wikipedia.org/wiki/Fn_key#cite_note-0.

The stock w510 BIOS has an option to swap fn and ctrl, but that's apparently the limit of the customizable parameters.

I have tried to achieve the same thing. When the function is pressed, it is intercepted by the ThinkPad Power Management service (ibmpmsvc.exe for me), which follows a routine to hibernate the computer (makes the hiberfile if not present). The TP PM does not consult Windows Power Management preferences.

The only way I know of to disable the F12 hibernate function is to avoid TP PM. You can either kill the process, or uninstall it, or disable the service. However, that will disable the other Fn-functions as well. I think you can be confident that nobody will use the shortcut. Fn must be pressed before F12, so the chance is small that a cat will trigger it. Most people I know interpret the blue Fn markings as well as Egyptian Hieroglyphics: unless they use a ThinkPad themselves, they never give any thought to using the Fn functions. But even if they know the power management shortcuts, people who borrow my computers tend to leave them as they found them: usually on or off, nothing in-between.
