The issue exists with the latest development release of Ubuntu ( utopic-
desktop-i386). The screen remained black after resume from standby and
the computer didn't respond. I tried the life-system from DVD.

Title:
  Dell Inspiron 1525 - suspend/resume failure

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  When laptop is in standby and lid is opened, the screen remains black
  and the computer doesn't respond. LEDs and fans are active. The
  computer is usable again after a restart.

  This bug was not present in previous installed Ubuntu 13.10.

  Resuming from standby works in most cases with a standby hook which
  kills pulseaudio and unloads the module snd_hda_intel before standby
  and reloads snd_hda_intel after resume. See attached file. In some
  cases the computer doesn't go to standby when I close the lid with
  this standby hook active. When I reopen the lid, the display remains
  black and the computer doesn't respond. So this workarround is not
  reliable.

  When I boot Ubuntu 14.04 with Saucy kernel 3.11.0-19-generic or
  mainline kernel 3.12.18-031218-generic for trusty, resume from standby
  works fine.
