Ubuntu 11.04 on Thinkpad T420 with HDAPS Working

[mejo]

followed instructions but now i see:

'LilArooni ~/tp-smapi-0.40: sudo modprobe tp_smapi
FATAL: Error inserting tp_smapi (/lib/modules/2.6.38-8-generic/updates/dkms/tp_smapi.ko): No such device"


LilArooni ~/tp-smapi-0.40: sudo modprobe hdaps
FATAL: Error inserting hdaps (/lib/modules/2.6.38-8-generic/updates/dkms/hdaps.ko): No such device
LilArooni ~/tp-smapi-0.40:

.. any ideas what to do now? t420 with 11.04 here.

you need to patch tp_smapi first, and rebuild the module.

1. install tp_smapi sources: 'sudo apt-get install tp-smapi-dkms'

2. edit the file at /usr/src/tp-smapi-0.40/thinkpad_ec.c, add the following line at line 463:
TP_DMI_MATCH("LENOVO", "ThinkPad T420"),

3. remove the installed kernel module: 'sudo dkms remove -m tp-smapi -v 0.40 -k $(uname -r)'

4. build the kernel module with modified sources: 'sudo dkms build -m tp-smapi -v 0.40 -k $(uname -r)'

5. install new built kernel module: 'sudo dkms install -m tp-smapi -v 0.40 -k $(uname -r)'

6. load the new installed kernel module: 'sudo modprobe tp-smapi'

Hi, I am trying to use tp_smapi on my ThinkPad Edge 15, I did the patching and building as detailed, but I still get the error-

shaan@shaan-laptop:~/Desktop/tp-smapi$ sudo modprobe tp_smapi 
FATAL: Error inserting tp_smapi (/lib/modules/2.6.38-10-generic-pae/updates/dkms/tp_smapi.ko): No such device or address

I tried both TP_DMI_MATCH("LENOVO", "ThinkPad Edge15") and TP_DMI_MATCH("LENOVO", "ThinkPad Edge 15").

Any suggestions?

Hi, could you just download the attached file? Then do:

sudo aptitude remove tp-smapi-dkms

Next extract the file and install the extracted file:

sudo dpkg -i tp-smapi-dkms_0.40-9_all.deb

Tell me if it's working.

How to know it's really working well?

Great HDAPS instructions, worked like a charm.

Thinkpad T520
Ubuntu 11.10
tp_smapi is at 0.41 now.

The tp_whitelist in 0.41 now contains an entry for ("LENOVO", "ThinkPad"). I took a guess and added ("IBM", "ThinkPad T520") and ("LENOVO", "ThinkPad T520"). I don't know if this change was necessary, I don't know which of those two, if any, are correct, I don't know if it works without this modification -- I didn't try it. =) But, for reference, mine is:

	struct dmi_system_id tp_whitelist[] = {
		TP_DMI_MATCH("IBM", "ThinkPad A30"),
		TP_DMI_MATCH("IBM", "ThinkPad T23"),
		TP_DMI_MATCH("IBM", "ThinkPad X24"),
		TP_DMI_MATCH("IBM", "ThinkPad T520"), /* added */
		TP_DMI_MATCH("LENOVO", "ThinkPad"),
		TP_DMI_MATCH("LENOVO", "ThinkPad T520"), /* added */
		{ .ident = NULL }
	};

I did have to install debhelper, quilt, and dkms -- they all worked as-is.

Thanks again!

Do "find /" and watch it stop when you bump the machine.

As for working well... I suppose you could take two identical ThinkPads, load hdaps on one of them, and count how many times you need to throw each one down the stairs before the hard drive crashes. If all goes well, you should get a few more tosses out of the one with hdaps.
