Hi,
I've noticed that my thinkpad is going through almost 15W of power on battery (reported by powertop).
The number one user of power is my wireless chip at 5W (that is 2.5x more power than my lcd screen).
iwconfig states that the chip is being power managed and powertop also reports that powermanagement for the wireless is activated.
If it is being power managed, why is it the #1 power sucker on my laptop?

same here, im really worried. intel 6205 consumes around 5-7W according to powertop.

My wireless card's power usage is starting to worry me now. It will peak at ~11W every now and then, but averages 5-7W with only light usage.
Output from powertop:
Power est. Usage Events/s Category Description
10.9 W 6850 pkts/s Device Network interface: wlan0 (iwlwifi)
6.94 W 2678 rpm Device Laptop fan
2.70 W 0.0% Device Display backlight
2.70 W 32.9% Device Display backlightI'm using the tlp scripts from AUR on my Thinkpad T520. I'm starting to wonder if laptop-mode-tools would be better. What are the differences between tlp and laptop-mode-tools?

I think laptop-mode-tools has more features than TLP, but it is harder to configure. TLP is aimed to provide a simple configuration through /etc/default/tlp. Furthermore TLP is made for ThinkPads. You can set battery thresholds in the config-file and the settings are aimed towards TinkPad related hardware.
However, there are some features, laptop-mode-tools does not provide:
- PHC-Settings (if you use a phc-kernel)
- PCIe ASPM
- Radeon KMS Power Management
- ThinkPad Battery-Threshold
- Turn off Ultrabay device
- Turn off Bluetooth, Wifi, WWAN on startup
