Hello,
I have a Asus K53T laptop. My system setup is Windows 7 dual booted with OpenSuse 13.1 x64.
I noticed that windows consumes significantly less energy compared to OpenSuse, which is a bit surprising considering that windows loads a lot of **** aware plus an antivirus, things that are not running on OpenSuse.
I am looking for advice on how to configure OpenSuse power options, so my battery lasts as long as it does on windows.
Hi! There are a few good ways to save power. The largest boost I noticed is to install laptop-mode-tools. I am going to use some links to the arch-wiki to help you find more info, but aside from references to their package manager it should mainly work exactly the same on openSUSE.
https://wiki.archlinux.org/index.php/Power_saving
https://wiki.archlinux.org/index.php/Laptop_Mode_Tools
You can use powertop to see how much energy you are using.
I also recommend adding this line to /etc/sysctl.conf it should help to keep writes in bursts.
vm.dirty_writeback_centisecs = 1500
Thanks for the suggestions 
I am reading trough Laptop Mode features. Is it mostly done automatically or do I actually need to configure something?
I made sure that I have hdparm and cpupower installed.
Also trying to interpret the results provided by powertop. I am getting around 450wakeup/s with the PC idle, but I don’t really have anything to compare this to. I noticed that the CPU usage displayed by powertop is usually higher than the one displayed by System Monitor, but have no idea what conclusions to take out of this!

Does it have an hybrid video setup, like Nvidia plus Intel graphics?
Without the proper drivers, the Nvidia card will be powered even if not
used.

Hi,
Yes, I have a dual graphics set up in my laptop. I have the AMD APU A6 CPU (integrated graphics) plus the AMD HD7670 dedicated card.
I am already using the AMD proprietary drivers

Well, using the integrated graphics on the CPU uses much less power. How
to disable the dedicated card, I do not know. I guess that the idea is
to use the integrated g. on battery, and the card while on mains.
Possibly Windows side handles this automatically and correctly.

bingo…
it seems that hybrid graphic is still a nightmare on linux.
take a look on this man, maybe this will give you a clue:

read the chapter 3.2…
Hi,
I have followed all the suggestions, and my battery has been lasting a substantially higher amount of time.
But I am having a problem that I believe is caused by laptop mode tools. Every time I use a USB mouse it gets switched off after a few seconds, and wakes-up if a press one of the mouse buttons, but not by moving it…
For what I have read, I need to blacklist my USB mouse on “usb-autosuspend.conf”.
On that file I see the following entries.
AUTOSUSPEND_USBTYPE_BLACKLIST=""
AUTOSUSPEND_USBID_BLACKLIST=""
I think it would be best to use USBTYPE so I could blacklist all mouses (if that’s possible?), I am just not sure on what should go there, to accomplish that.
Still not sure what parameters to use :
(bump)

I have an idea about this, but I need having a good look at my laptop,
and then write it here. But I always forget when it is powered up. Sorry.
I need to do some errands… perhaps when I come back.

I’ve been busy… highly technical tasks such as cutting iron bars to
size or pruning greenery on a garden
Yes, I was going to suggest looking at
“/etc/laptop-mode/conf.d/usb-autosuspend.conf”.
You could try this section:
# The list of USB driver types that should not use autosuspend. The driver
# type is given by "DRIVER=..." in a USB device's uevent file.
# Example: AUTOSUSPEND_USBTYPE_BLACKLIST="usbhid usb-storage"
AUTOSUSPEND_USBTYPE_BLACKLIST=""
(errata corrected above)
If you run “lsmod | grep usb” you can find out which are in use.
The other one:
# The list of USB IDs that should not use autosuspend. Use lsusb to find
out the
# IDs of your USB devices.
# Example: AUTOSUSPEND_USBID_BLACKLIST="046d:c025 0123:abcd"
AUTOSUSPEND_USBID_BLACKLIST=""
As the comment say, using “lsusb” should list the IDs. It gives an
output like this:
minas-tirith:/etc/laptop-mode # lsusb

But as you see, we can not see which one is the mouse. Let’s try with
“verbose”. …] Nope, I can not identify my touchpad.
From /var/log/Xorg.0.log, I know this:

I think mine is not connected via usb at all. It is connected via
something they called “i8042 AUX port”. :-?
(I see an item “/sys/devices/platform/i8042/power/autosuspend_delay_ms”
which could be interesting to manipulate)
I have a note from a thread dated 2012-09-11, on which they use:
AUTOSUSPEND_USBTYPE_BLACKLIST=“usbhid”
This should help you, I think; your mouse is external. But of course,
the entire usb bus will remain powered up.

Hi,
I am not being very successfully in getting the USB driver type. My external usb doesn’t seem to show up at all, when I run “lsmod | grep usb”
$ lsmod | grep usb
usb_storage 62062 1 ums_realtek
That’s my MMC/SD/MS card reader.
Also tried “lsmod | grep mouse” but it doesn’t return anything.
dmesg gives me this:
$ dmesg |grep -i mouse

Well… we can use the ID:
AUTOSUSPEND_USBID_BLACKLIST="093a:2510"
Try and find out if that works
(the driver I think is “hid-generic”)

Using the ID works
I will try using that driver, and see what happens.

No, don’t (IMO). The ID is more precise, as it only affects that device.
If you happen to plug in another device that uses the same driver, it
will not be affected.
