Error parsing arguments

[sheef0]

Hi there!
I was trying to unlock CPU undervoltage on my hp gaming laptop 15-dk1. when I run .\setup_var.efi CpuSetup:0xDA=0x0 I get the error "Error parsing arguments: Unexpected value: CpuSetup:0xDA=0x0" . Any Ideas?
Thanks !

Note the following:

The new usage document is for git master version. For current newest release (0.2.x), refer to document of that version.

To use the new-style syntax, feel free to use a fork I created a while ago: https://github.com/GeographicCone/UefiVarTool

Hey thanks a lot for the answer ! So I used the right syntax and I got "error while writing data ... Variable CpuSetup WRITING PROTECTED". Do you think there is a way around this other than physically flashing the bios? I'm desperately trying to undervolt the cpu on my laptop. Cheers!

Do you think there is a way around this

Not by using this utility, which simply makes a call to UEFI Runtime Services:

setup_var.efi/src/utils.rs

Lines 166 to 167 in 7cc8929

	runtime_services
	.set_variable(&var.name, &var.vendor, var.attributes, &var.content)

Unless you have a setting for this in your BIOS (UEFI) Setup, ways to bypass any such restrictions are platform-dependent.
