Hi Below is the output of 'grep -n thinkpad_acpi /var/log/messages' on my x230 model 2325-77G ########## 504:Oct 15 07:40:13 localhost kernel: thinkpad_acpi: THERMAL ALERT: unknown thermal alarm received 505:Oct 15 07:40:13 localhost kernel: thinkpad_acpi: unhandled HKEY event 0x6040 506:Oct 15 07:40:13 localhost kernel: thinkpad_acpi: please report the conditions when this event happened to ibm-acpi-devel@xxxxxxxxxxxxxxxxxxxxx 507:Oct 15 07:40:13 localhost kernel: thinkpad_acpi: EC reports that Thermal Table has changed 557:Oct 15 07:40:13 localhost kernel: thinkpad_acpi: EC reports that Thermal Table has changed ########## I'm using CentOS 6 with all current patches applied. Most likely not relevant: - Hd is replaced by a Samsung 840 Pro 256GB SSD - Memory is upgraded to 16 GB (2x Kingston KTL-TP3C/8G) Unfortunately, it seems I can't create a ThinkWiki user at the time. The data for my model as should have been listed by http://www.thinkwiki.org/wiki/List_of_DMI_IDs is: || LENOVO || 232577G || ThinkPad X230 || LENOVO || 232577G || Win8 Pro DPK TPG || LENOVO || Not Available || LENOVO || G2ET95WW (2.55 ) || 07/09/2013 || <nowiki></nowiki> Latest BIOS is 2.56, only fixes some USB memory stick problems. Thank you for doing a great job. If there's anything I can do to help, please let me know.
