Laptop Battery drains extremly fast!

sk8harddiefast · Feb 10, 2015

Hi. I know. Passed a lot of time from my last login. Sorry. I didn't forget you!
Here Is my problem.
I have a Lenovo Ideapad p400 touchscreen. Using Linux my battery was keeping at least 3 hours.
Now with FreeBSD almost 30 minutes! I follow this wiki: https://wiki.freebsd.org/TuningPowerConsumption
I made everything of them but still battery drains too fast! Is decreasing ~1% every 2 minutes! Before this was decreasing ~1% every minute!!! All this in idle state!!!
Writing this lines my battery went from 86% to 82%! Is insane!
How can I tweak my power management?

Just to confirm, have you enabled powerd(8) by adding powerd_enable="YES" to /etc/rc.conf?

Further discussion on the use of powerd(8) is here: Thread 172

sk8harddiefast · Feb 11, 2015

Yes. Ok. Now My settings.

I use 10.1-RELEASE with default kernel for now.

On /boot/loader.conf

Code:

debug.cpufreq.lowest=600
hint.p4tcc.0.disabled="1"
hint.acpi_throttle.0.disabled="1"

On /etc/rc.conf

Code:

powerd_enable="YES"
powerd_flags="-a maximum -b adaptive -i 85 -r 60 -p 100"

My /etc/sysctl.conf

Code:

dev.cpu.0.cx_lowest=C5
dev.cpu.1.cx_lowest=C2
dev.cpu.2.cx_lowest=C5
dev.cpu.3.cx_lowest=C5
dev.cpu.4.cx_lowest=C5
dev.cpu.5.cx_lowest=C5
dev.cpu.6.cx_lowest=C5
dev.cpu.7.cx_lowest=C5

My battery still drops too fast! Almost 1% per minute! Using it like this in 6 months I will need a new battery!
PS. The only I want is a normal react of my laptop as all the laptops in the world. Full power on AC and on battery but do economy when is open and I don't use it.

Hello!
Just a wild guess: this laptop has NVidia video card. Which driver do you use? Which NVidia profile (in settings) do you select?

sk8harddiefast · Feb 11, 2015

Hi nekoexmachina! How are you?
Has Intel HD 4000. I am in a new fresh install. I didn't even fetched the ports.
I have no reason to go further if my battery cannot hold at least 2 hours of hard compiling on battery.

sk8harddiefast · Feb 11, 2015

Ι used Manjaro Linux on laptop. I went back to FreeBSD because just I love FreeBSD. I want to make it work. On my desktop works perfect everywhere 4.5 years now.
On laptop I am disappointed. Wifi, brightness etc, will work. Now or in the near future. Some things will be hacked to do my job. Is not this the problem.
But power? On a laptop is the biggest problem! Imagine the reality.
Battery 100%

Code:

cd /usr/src
make buildkernel KERCONF=MYKERNEL

make installkernel KERNC.....bzzzzzz Battery 0%. Please connect charger on your laptop to install the kernel!!!

Code:

Sudo portsnap fecth update
portupgrade -a

Battery 0%. Please connect charger on your laptop to install the rest updates!!!

Code:

ssh ember@192.168.1.18

Battery 0%. Please connect charger on your laptop to connect to desktop!!!

Ok. I Finished my system after a month of hard tweaking.
Lets Power on.

Battery 0%.
Battery damaged.
Please change battery on your laptop to boot into FreeBSD!!!

As you understand this make the laptop unable to run FreeBSD.

Please post the 'dmesg' output after boot so we can see what hardware is in the thing. Thanks!

Right, ivy bridge.

So, do this:
# pkg install intel-pcm
# kldload cpuctl
# pcm.x 1

Run it for a few seconds, hit ctrl-C and paste the results here.

It's likely that the CPU isn't going fully into deep sleep states and your battery is being chewed.

Then put this in /boot/loader.conf, reboot, and try again:

Code:

drm.i915.enable_rc6=7

sk8harddiefast · Feb 11, 2015

So to be late to answer. I went to get my girlfriend from the University.
This are the results:
http://pastebin.com/GUJQqtX6
I upload them to pastebin because forum cannot upload a big text
Also I add this line to /boot/loader.conf

Code:

drm.i915.enable_rc6=7

sk8harddiefast · Feb 13, 2015

Here are the right configurations for Power Management.

1) According the developers we shouldn't have -i (idle%) higher than -r (run%). The defaults are
-i 50 -r 75.

2) C-states:

In /etc/sysctl.conf, this is wrong:

Code:

dev.cpu.0.cx_lowest=C5
dev.cpu.1.cx_lowest=C2
dev.cpu.2.cx_lowest=C5
dev.cpu.3.cx_lowest=C5
dev.cpu.4.cx_lowest=C5
dev.cpu.5.cx_lowest=C5
dev.cpu.6.cx_lowest=C5
dev.cpu.7.cx_lowest=C5

Apart from the oddity of C2 on cpu1, setting these is NOT the way to do this, you have to set hw.acpi.cpu.cx_lowest instead, then cpufreq(4) uses that to set the individual cx_lowest per CPU (and all to the same state) which is usually and best accomplished by setting the below in rc.conf, as stated in https://wiki.freebsd.org/TuningPowerConsumption:

Code:

 performance_cx_lowest="Cmax"
economy_cx_lowest="Cmax"
