Sharing Linux: Problem Solved, How to Show 'Battery Status' Indicator on Ubuntu 12.04 Precise Pangolin (Lepi = Toshiba Satellite L645)

Sharing Linux: Problem Solved, Battery Status Indicator on Ubuntu 12.04 Precise Pangolin (Lepi = Toshiba Satellite L645) 

before.. 

after..

Have tried to how to install battery status, or battery state, or battery indicator, or battery icon, or battery power management, or battery notification, or battery percentage, or batmon.app (maybe adekroisa have tried) with the notebook/netbook/lepi/laptop that have same specification with this? check this out..

Spesification:
Merk: Laptop (lepi) Toshiba Satellite L645
OS: Linux >> Ubuntu 12.04 Precise Pangolin
Kernel Linux 3.2.0-26-generic-pae
GNOME 3.4.1

Case: Machine is NOT running on battery and hence we cannot measure power usage
sudo add-apt-repository ppa:colin-king/
sudo apt-get 
sudo apt-get install 
sudo pm-powersave true
powerstat
on adekroisa's lepi >> "Machine is NOT running on battery and hence we cannot measure power usage."

How can I install that all apps that I mention above, I just realeased that the problem is about Fix Toshiba battery issue for Linux. Yes, thats right on some Linux. Toshiba are two set data boot that give information OS hardware what is include in machine. Windows can read it well, but Linux notyet. We need to build kernel on our own to create it happen. We need to take DSDT from machine with ASL modification and AML DSDT can be compiled.

DSDT mean Differentiated System Description Table.

OS lepi=Ubuntu, OS hp=Android, that great.. but how if the battery cannot be detected?? hemm.. look cupu.. wkwk

Don't forget to be super user, sudo su on terminal first. To launch the terminal just type 'Ctrl+Alt+t'
sudo su
then, type your password.

[STEP 1] Check battery detection status on lepi (Toshiba Satellite L645)
cat /proc/acpi/battery/BAT1/*

like this ye? present: no
yeah, its mean that battery is not detected

[STEP 2] Now, get the original DSDL of machine (Toshiba Satellite L645's with Ubuntu 12.04 Precise Pangolin 'OS Linux')
cat /sys/firmware/acpi/tables/DSDT > DSDT.dat

[STEP 3] Disassemble it with iasl, failed? try to install it before
apt-get iasl
iasl -d DSDT.dat
vi DSDT.dsl

note:
search for line : OperationRegion (EMEM, SystemMemory, 0×FF808001, 0×FF)
then replace it with : OperationRegion (EMEM, EmbeddedControl, 0×00, 0×FF)
save it.

[STEP 4] Build the DSDT, in condition of super user mode on terminal (for me: root@ar-mscdr:/home/roisa#). This will creat a file DSDT.hex for kernel recompilation.
iasl -tc DSDT.dsl

if you find error, try to edit again
gedit DSDT.dsl

Line 2656 changed to
0xFEB00000,         // Length

Line 2663 changed to
0×00005000,         // Length

iasl -tc DSDT.dsl

[STEP 5] install some package (necessary packages)
apt-get install fakeroot kernel-wedge build-essential makedumpfile kernel-package libncurses5 libncurses5-dev

apt-get build-dep --no-install-recommends linux-image-$(uname -r)

needs enough time, depend on connection :)

[STEP 6] play on folder 'source'
mkdir /root/source
cd /root/source

apt-get source linux-image-$(uname -r)

[STEP 7] Play on linux folder (as your kernel version, ex: linux-3.2.0 on adekroisa's lepi)
root@ar-mscdr:/home/roisa# cd /root/source/linux-3.2.0/
cp -vi /boot/config-3.2.0-26-generic-pae .config

note: 3.2.0-26-generic-pae its depend on yours, its kernel version on adekroisa's lepi
cp /home/roisa/DSDT.hex /root/source/linux-3.2.0/include/

[STEP 8] Play with file .config and the word 'config'
gedit /root/source/linux-3.2.0/.config

try to change like this (save and quit):
CONFIG_STANDALONE=n
CONFIG_ACPI_CUSTOM_DSDT=y
CONFIG_ACPI_CUSTOM_DSDT_FILE="DSDT.hex"

  start compiling the kernel,
  first: load the .config file,
  second: save menu for .config file and last: exit.
  note: maximize the terminal window

  make menuconfig

[STEP 9] Get Knowledge about your concurrency level (case: adekroisa's lepi have a Intel Core i3 processor)
root@ar-mscdr:/home/roisa# cat /proc/cpuinfo | grep -i processor
processor : 0 
processor : 1
processor : 2
processor : 3

adekroisa got 4 processor, its mean that concurrency are 4+1=5
export CONCURRENCY_LEVEL=5

[STEP 10] Let's start, my custom kernel is adekroisa, hehe.. its my name get from 'Roisatul Azizah' called 'Adek Roisa' or 'Roisa', recompiling kernel.. but you also can do it without recompiling kernel. 
make-kpkg clean

fakeroot make-kpkg --initrd --append-to-version=-roisa kernel-image kernel-headers

note: this take several time (wkwkw.. much time dink.. :)
on adekroisa's lepi its start before adzan and pray ashar, and finish before maghrib (2.30 pm until 4.30 pm).. wow.. 2 hours.. Alhamdulillah.. hope it will be useful.. size 6.5GB.. hmm. superr..
preview here.

[STEP 11] Let's find the built kernel 'roisa' not 'adekroisa' or 'roisatul azizah' or 'roisa mscdr'
cd /root/source
dpkg -i linux-image-3.2.19-adekroisa-10.00.Custom_i386.deb
dpkg -i linux-headers-3.2.19-adekroisa-10.00.Custom_i386.deb

make initramfs:
update-initramfs -c -k 3.2.19-roisa
update-initramfs: Generating /boot/initrd.img-3.2.19-adekroisa

update-grup

Finish, wokee.. restart lepi (laptop) to feel the great effect..

NOTE: special for ATI user or ATI Mobility Radeon, after this recompiled 'new custom kernel' do this to show your missing launcher, dash and navbar, check ki dot:
sudo apt-get install --reinstall unity && sudo reboot

or this
sudo apt-get install fglrx

Finish, wokee.. restart lepi again to feel the great effect..

Alhamdulillah.. how it will be useful :)
