Kabanov Dmitry, thank you for reporting this and helping make Ubuntu better. As per http://www.dell.com/support/home/us/en/04/product-support/product/precision-t7500/drivers an update to your BIOS is available (A16). 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

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.

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

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

Thank you for your understanding.

Title:
  Resuming after suspend I get only black screen

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  I use Dell Precision T7500 machine.
  My computer is suspended automatically.

  When I push the power button to wake up the machine, I get only black screen.
  I can't switch to another tty, probably, although I cannot confirm because of the black screen.

  If I uncheck the checkbox "Require my password when waking from suspend", then my computer
  wakes up correctly.
