Re: tp_smapi 0.40-9 incompatible with thinkpad w520
[6.385415] thinkpad_acpi: ThinkPad BIOS 8BET44WW (1.24 ), EC unknown Yuck. It is failing the DMI version string checks. [8.814881] thinkpad_ec: no ThinkPad embedded controller! thinkpad_ec is less nice about it than thinkpad-acpi. No W520 in thinkwiki DMI ID, so I have no idea what's wrong. -- One disk to rule them all, One disk to find them. One disk to bring them all and in the darkness grind them.

Re: Re: tp_smapi 0.40-9 incompatible with thinkpad w520
Hi, Henrique, Yeah, thanks for your analysis. So do you know how to report the problem to lenovo so hardware engineers there could be aware of this problem or should we wait for updates of tp_smapi from debian community? Many thanks!

Re: tp_smapi 0.40-9 incompatible with thinkpad w520?
Hi, all, Another symptom, although on the panel the gnome power management applet indicates the battery is charging, actually it is not. Now with the power adapter connected, the laptop cannot charge the battery! I think the incompatibility of tp_smapi with bios gives the wrong control on battery charge threshold.

Who said anything about a bug in the thinkpad firmware? Until I get to see the dmi string, I don't know what is happening. It is far more likely that the driver needs to be updated. Sorry for the misunderstanding. I got a wrong idea about the problem. I know that I should wait for an update from debian now. Thanks!

tp_smapi 0.40-9 incompatible with thinkpad w520?
Hi, Before the bios update made available on 19th May, my thinkpad w520 couldn't boot into debian wheezy/sid even after a successful installation. However the latest bios update solved that issue. But still the tp_smapi can not be loaded. usr@debian-thinkpadw520:~$ sudo modprobe tp_smapi [sudo] password for usr: FATAL: Error inserting tp_smapi (/lib/modules/2.6.39-1-amd64/updates/dkms/tp_smapi.ko): No such device By the way, if I remove the hard drive to install it to an old T60p, it boots into debian and loads tp_smapi normall. Any ideas about loading the module properly? Thanks in advance!! -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe. Trouble?
