No power status shown

[Haituga]

Hi,
I was looking for a good distro for my Surface Pro 3 and came across elementary. After a few tests within a VM on my main PC I came to the conclusion that Elementary OS seems quite fitting for me and I love the GUI, the support you get from this repo, the software management and the quick accessibility. But I have the problem that is best described here. Instead of a battery life status, all I've got displayed is a little sun that allows to change the brightness and allows me to access the power settings. I tried some workarounds which I got from the issue tracker from this very repo and even against your advice installed tlp and powertop. But the GUI update that should came with laptop-mode-tools (which I uninstalled for tlp) or tlp isn't functioning.
I hope you can help.

Sincerely,
Lukas | Haituga
