Centos 7.3 Installed

Lakshmana

I have installed Centos 7.3 KDE version in my machine now. For learning RHEL class. I face one issue is that battery indication is shown as 0% but the charging is happening. How to install only that package in the machine. Since i have yum update it asking to update up to 400 MB. Now my data is less. So need to update only Battery indication. How to do this ?

Reid Cooper

You need to find the name for that package. Once you have that, the command to install a package is...

yum install packagename

I would assume that to some degree this is hardware dependent. Maybe CentOS 7.3 does not support your laptop. CentOS is not known for working well with laptops, it's not really designed for that. And at this point, CentOS 7 is decently old and 7.3 is not up to date. The combination easily might simply mean that you don't get a battery indicator.

Whether the name of the package helps?

@reid-cooper how can i find the battery package name?

It's required. If you don't know it, or we can't figure it out, there is no way to install it.

I don't know, perhaps knowing what hardware you are using would give us a lead?

If nothing else, get off of 7.3 and move to 7.4. You can check the battery from the cli by typing acpi. If that works, it's probably whatever KDE is using for measuring the battery doesn't work with your system.

@stacksofplates for acpi "command not found" is the error

You'll have to install it.
yum install acpi

The package has one more letter in the name. Should be this...

yum install acpid

Then you can fire it up like this...

systemctl start acpid
systemctl enable acpid

It's systemctl not sysctl. Two different things.
