Repeated Error Message Almost In Every Second: "toshiba_acpi: Unknown key 401"

[Rendy Eko Prastiyo]

First of all, sorry for my bad English.

I'm using Ubuntu 14.04 32bit on my Toshiba L645 core i3. The problem is: something is like firing a key up when I press and hold a key. It happened not just in terminal, but everywhere. I guess the problem is caused by toshiba_acpi as the syslog said (10 recent lines):

Rendy Eko Prastiyo, thank you for reporting this and helping make Ubuntu better. As per http://toshiba-asia.com/sg/support/drivers an update to your BIOS is available (2.70). If you update to this following https://help.ubuntu.com/community/BIOSUpdate does it change anything? If it doesn't, could you please both specify what happened, and provide the output of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date

For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette .

Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful. As well, you don't have to create a new bug report.

Once the BIOS is updated, then please mark this report Status Confirmed.

Thank you for your understanding.

I confirm that upgrading my BIOS to version 2.70 helps me solving this problem.

Thank you for the assistance, Mr. Penalver.
