| 1 | power saving for maximum battery on x240. | |
| 2 | ||
| 3 | First, let's enable power-saving functionality on all devices. | |
| 4 | ||
| 5 | Then, comes the most important part. Keep you cpu-usage low, all the time. | |
| 6 | I can easily get my laptop to draw 20watts if i feel like it (at least in short bursts), 15watts on average is not impossible in any way and will drain the battery in 1/3 of what i'm getting from it. | |
| 7 | ||
| 8 | Become a slave under powertop for a while to get a feeling for what continuously needs cpu, and what doesn't. that way you know what to avoid when battery really matters. :) | |
| 9 | ||
| 10 | what to do: | |
| 11 | Install tlp: | |
| 12 | # sudo apt-get install tlp tlp-rdw | |
| 13 | ||
| 14 | ||
| 15 | configure tlp, i set everything to battery-mode, always, that way i don't mind any potential performance drop when i unplug the laptop.. It also charges faster (since there's more power available for charging). | |

| 255 | Install suspend-tab addon in firefox to suspend tab's you don't have active at the moment (saves cpu-cycles, makes suspended tab's restart when you open them) | |
| 256 | https://addons.mozilla.org/en-US/firefox/addon/suspend-tab/ | |
| 257 | I've configured suspend-tab to suspend tabs after 30seconds. | |
| 258 | Also, Install flashblock (flash sucks a lot of cpu..) | |

| 260 | tlp provides features some nice commands to easily rfkill the different radios. | |
| 261 | wifi on/off | |
| 262 | bluetooth on/off | |
| 263 | wwan on/off | |
| 264 | ||
| 265 | I always try to remember to kill the radios i don't need. | |
| 266 | ||
| 267 | As long as cpu is idle power-usage should be at it's lowest. | |
| 268 | Get a usable baseline measurement: | |
| 269 | I reboot, log-on to my desktop, start a terminal (i use urxvt), start powertop, put display on lowest, disable wifi/wwan/bluetooth and let the machine sit for ~1minute, then check the discharge rate powertop is reporting, and also check the number of wakeups reported. | |
| 270 | ||
| 271 | My X240 has a bit high baseline measurement at the moment since i'm at work. I need firefox and hipchat in the background and i'm connected over 3g, but wifi and bluetooth is off, i lowered the display to the lowest possible setting for this measurement. | |
| 272 | Also, Powertop only reports the discharging battery, so if you have two like i do, one internal on 23.7wh and one external of 77.2wh, you need to keep track of this (it shows the currently discharging one in gnome-power-statistics, or "tlp stat") | |
| 273 | ||
| 274 | My estimated runtime on the dimmest brightness is about 15hours, that's with about 75% remaining (been running on battery for 3hours) add the other battery and it ends up somewhere at 21-22hours, | |

| 350 | Note that cpu is in c9 or c10 all the time.. no load on the system should put it there immediately. | |
| 351 | Also, the gpu is in rc6 all the time (no unneccesary screen redraws) which is due to the i915 stuff we did earlier. | |
