 |

I have a problem on my laptop. It seems that my /proc/acpi/battry and ac_adapter is empty
My laptop is an Acer Travelmate 2301 LCi
Is there any workaround? |

There may be a problem with the DSDT provided by the laptops bios. There is a howto on how to use a patched DSDT on these forums https://forums.gentoo.org/viewtopic.php?t=122145.
Otherwise you may not have compiled or loaded the batters modules of the kernel ACPI.
Hope this helps |

Yeah, I did try that howto... however I'm not great with hacking the code 
But I give it a try again |

good luck
did you check to see if there is an already fixed DSDT on acpi.sourceforge.net |

yup, and now as I understand it's not DSDT that's messing with me, it's ECDT.
so I guess I just have to wait for a patch  |

sorry for the bad news, but i think you have a smart battery.
known smartbattery acer models:
Travelmate 4001 LMi/WLMi (mine)
Travelmate 4002 LMi/WLMi
Travelmate 8005LMi
Travelmate 4501WCi
some Travelmate 292 (Extensa 2920)
Extensa 3001
now probably travelmate 2301 LCi.
the problem with the smart battery is that there is NO linux support for it. so you will be left with no AC or battery information for some time.
i'm still to find out a method for people to diagnose the presence smartbatteries.
yes, the DSDT has some warnings that can be fixed but won't make it work if you have a smartbattery.

don't hold your breath. there isn't many people willing to write such and those who are (like me) don't have the time or the knowledge/experience to do so.l
the acpi mailing list has little activity on this subject, but some people there are working on it.

no.
the drivers are being built on a spare-time basis.
as far as i know there is no useful work yet, except for documentation research.

I've been looking for ACPI battery support for my ACER TRAVELMATE 4002 LMI and finally I found this post.
What's the diference between SmartBattery and normal Batteries? How can I compute remaining time of my battery? I've noticed that with windows it can work 4 hours more or less at minimus. But if I don't know how long battery left the computer will halt with any notice?
I'm really annoyed.

the smartbattery system is a structured and modular system for battery management. It supports more than one charger, more than one battery and works standalone. You can communicate with it's several components and control their functioning, but if you leave it alone, it will work without any direct or indirect OS or user influence.
basically it's a well built battery system. unfortunately it isn't a standard. Don't know if it's a question of time or not. the fact is that smartbatteries are rare.
If you don't have a smartbattery driver, there is no way to compute it's battery remaining charge, thus you'll have to wait (hopefully not for long) for a driver that reads your smartbattery settings and information.

hi everyone,
smartbattery test drivers are already written (not by me) and things are looking good. they still need time to mature before thinking of inclusion on the main kernel.
Stay tuned. I'll post download links soon for people to try it out.

I've followed all notice from acpi-digest and I'm trying to patch my kernel. But I received always the same message:
| Code: | /bin/sh: line 1: /home/chewie/acpi/acpi_sbs-20050118/.tmp_versions/i2c-acpi-ec.mod: Permiso denegado

I've read to include EXPORT_FILE(acpi_ec_read) in the drivers/acpi/acpi-ec.c but it doesn't works. Do you have the same problem? How do you solve it?

here's the link for the most recent build
http://shayol.bartol.udel.edu/~rhdt/download/acpi_sbs-20050119.tar.gz
this is not for unexperienced users. documentation is not abundant.
one needs to patch the kernel just to export some symbols in drivers/acpi/ec.c and then just
modprobe i2c-dev
insmod i2c-acpi-ec.ko
insmod acpi-sbs.ko
and /proc/acpi/sbs appears with relevant information. also /proc/acpi/battery and /proc/acpi/ac_adapter appear as legacy proc files.

please describe your exact steps. error messages don't mean much without context

that errors appears when I do the make from the files from the tar archive. I've patched the kernel with the diff file and when I do the make this warning appears. If I run the make install and the | Code: | | modprobe i2c-acpi-ec |
doesn't work and returns that message:
[code]
FATAL: Error inserting i2c_acpi_ec (/lib/modules/2.6.10-gentoo-r4/i2c/i2c-acpi-ec.ko): Invalid module format
[code]
Anyone knows what could it be?[/code]

make and make install worked perfectly here
probing the i2c-acpi-ec module gave an error (the same one as described in the previous reply)
dmesg showed:
| Code: | i2c_acpi_ec: Unknown symbol i2c_del_adapter
i2c_acpi_ec: Unknown symbol i2c_add_adapter
i2c_acpi_ec: Unknown symbol acpi_ec_write
i2c_acpi_ec: Unknown symbol acpi_ec_read |
so the firts problem i came across was that i didnt have the i2c-core and i2c-dev module compiled in my kernel (be sure to compile them as modules)
| Code: | Device Drivers --->
I2C support --->
<M> I2C Support
<M> I2C Device Interface |
then i modprobed i2c-dev and now dmesg only shows the last 2 errors
| Code: | i2c_acpi_ec: Unknown symbol acpi_ec_write
i2c_acpi_ec: Unknown symbol acpi_ec_read |
so modprobing i2c-acpi-ec still doesnt work
the next thing i tried was reinserting the module
| Code: | # insmod i2c-acpi-ec.ko
insmod: error instering 'i2c-acpi-ec.ko' : -1 Unknown symbol in module |
and dmesg shows this agin:
| Code: | i2c_acpi_ec: Unknown symbol acpi_ec_write
i2c_acpi_ec: Unknown symbol acpi_ec_read |
so that didnt work at all :p
modprobing the acpi-sbs module works fine though |

ow my god, i got it working now 
this is what i did:
1) download the source from http://shayol.bartol.udel.edu/~rhdt/download/acpi_sbs-20050119.tar.gz
2) Patch the kernel
| Code: | # cd /usr/src/linux
# patch -d1 < [PATH_TO_SOURCE]/acpi-ec-2.6.10.diff |
3) Enabeling I2C support (be sure to compile as a module)
| Code: | Device Drivers --->
I2C support --->
<M> I2C Support
<M> I2C Device Interface |
also, make sure you have disabled acpi battery and acpi ac adapter support in your kernel
they can be found in 'Power Management ---> ACPI ( ... ) ---> '
4) Compiling the kernel and booting into the new kernel (example shows a 2.6 kernel)
| Code: | # make && make modules_install
# mount /boot
# cp System.map /boot/.... (whatever the system.map name is in your /boot)
# cp arch/i386/boot/bzImage /boot/.... (whatever the kernel image is in you /boot)
# umount /boot
# reboot |
5) modprobing all the right modules
| Code: | # modprobe i2c-dev
# modprobe i2c-acpi-ec
# modprobe acpi-sbs |
6) enjoy
congratz to all who helped develop this, realy nice work |
