[Bug 1449621] Re: Connecting to external display turns off laptop screen

 

Samuel, as per http://support.hp.com/us-en/drivers/selfservice/HP-
Pavilion-m6-1000-Entertainment-Notebook-PC-series/5259226/model/5273903
an update to your computer's buggy and outdated BIOS is available
(F.36). 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, and the information above is provided, then
please mark this report Status Confirmed.

Thank you for your understanding.
