 Posted: Tue Dec 16, 2003 11:50 pm Post subject: Optimizing Battery Life on HP Pavilion |
 |
|
I've got an HP Pavilion ze4560us and when I had WinXP installed my battery would last for about four hours, but now only lasts about 2 hours. I emerged cpudyn and added it to my default run level, but if I do /etc/init.d/cpudyn start I get this:
rohan:/home/cjohnson# /etc/init.d/cpudyn start
* Starting cpudynd...
* ACPI throttling support found, but hardware doesn't support it [ !! ]
So... I don't know what to do now. I was wondering what else I can do to squeeze out some battery life. Any help is appreciated.

What kernel are you using? You have to enable this for a 2.6.0 kernel:
[img:3e178e9116]http://mnm.uib.es/~gallir/cpudyn/powersave.png[/img:3e178e9116]
Also you need to add support for you processor's technology (speedstep, powernow, etc).
Then cpudyn will act accordingly like this:
| Code: | gustavo linux # cat /proc/cpuinfo
processor : 0
vendor_id : AuthenticAMD
cpu family : 6
model : 10
model name : mobile AMD Athlon(tm) XP2400+
stepping : 0
cpu MHz : 530.125
cache size : 512 KB
fdiv_bug : no
hlt_bug : no
f00f_bug : no
coma_bug : no
fpu : yes
fpu_exception : yes
cpuid level : 1
wp : yes
flags : fpu vme de pse tsc msr pae mce cx8 sep mtrr pge mca cmov pat pse36 mmx fxsr sse syscall mp mmxext 3dnowext 3dnow
bogomips : 1048.57 |

I have a HP Pavilion ze4145, but I'm having difficulties getting ACPI to function properly. I'm using the 2.6.0 kernel.
| Code: | root@laptop mizery # /etc/init.d/cpudyn start
* Starting cpudynd...
* Neither CPUFreq nor ACPI throttling support were found [ !! ] |
2.6.0 kernel configuration:
| Code: | │ │[*] Power Management support │ │

Although, I'm using grub and /boot/grub/grub.conf:
| Code: | title=Gentoo Linux 1.4 (2.6.0)
root (hd0,0)
kernel /boot/kernel-2.6.0 root=/dev/hda3 acpi=off |
Right now I'm removing the "acpi=off" and rebooting. My system hangs during the boot sequence:
| Code: | mtrr: v2.0 (20020519)
ACPI: Subsystem revision 20031002
spurious 8259A interrupt: IRQ7. |
That last line is new. I've never seen it before. Several times the system would hang at the previous line. I'm researching the new response now in hopes to find a solution myself.

| mizery, disable APIC and IO-APIC in your kernel configuration, then ACPI will load properly and you will be able to use cpufreq. |

I am trying to get gentoo installed on my HP Pavilion ze4560us and I am wondering about acpi and battery life. After I compile a kernel with acpi support, do I need to emerge anything else to get acpi to work? Such as acpid, and is there a howto as far as using this cpudyn?

| You'll need cpudyn and also a kernel patch to enable the frequency tables. |

Just wanted to thank you for this advice. My Sony Viao would get to the power down state, but wouldn't power off. After I disabled APIC and IO-APIC in my 2.6.4-gentoo-r1 kernel, it now powers off! It was just the clue I was looking for. I was really getting tired of manually shutting the thing off. Thanks Again! |
