Lenovo X121e wifi & 3G problem

GRUB...

The only way you could get any different results by editing GRUB is if the kernel module for this key combination is not being loaded as it should. I doubt that's the case.

To check, boot linux first when you can use Fn+F5 and use the command "lsmod" to see which kernel modules are loaded at boot. Then boot linux while unable to activate functions with Fn+F5 and use the same command. If there is no difference in the results and the acpi module is listed in both cases, editing GRUB woun't do anything to solve the problem.

You may just have to live with this limitation. There may be a bug in the acpi module, but it may be a limitation built into the way the hardware works.
