Ubuntu doesn't boot after laptop runs out of battery

[Vadim Peretokin]

If my laptop runs out of battery, the next time I start it up and put in my disk password, I get a black screen that goes nowhere. I always have to hard-reset the laptop in order for the OS to load after I put in the disk password.

Vadim Peretokin, as per http://h20564.www2.hp.com/hpsc/swd/public/readIndex?sp4ts.oid=5428311&swLangOid=8&swEnvOid=4192 an update to your computer's buggy and outdated BIOS is available (1.33). If you update to this following https://help.ubuntu.com/community/BIOSUpdate does it change anything?

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, if the problem is still reproducible:
1) Please provide the output of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date
2) Please make a comment specifically advising on if there was an improvement or not.
3) If the issue is still reproducible, please mark this report Status Confirmed. Otherwise, please mark this as Invalid.

Thank you for your understanding.
