I'm having some major issues with a Hewlett Packard Elitebook 755 G2 (EnergyStar) laptop in my office.
We bought this computer for use as an office/business workstations. The issue makes it now ineligible to use.
Issue:
The computer will not wake after hibernation or sleep. Attempts made to wake it is by integrated keyboard/mouse, and power-button. To be booted again, I need hard-shutdown the computer (with power-button), and remove all power-sources from the laptop for 5 minutes. It then boots normally with prompt on how to boot windows cause it was not shut down properly last time. After sleep the screen goes black after sleep, and does not come on until I do the procedures as described above. If I try to boot computer before 5-7 minutes, the computer is in a standstill with a black screen, though after 30 seconds, the fans start to speed up (as if the computer needs to be cooled down).

When booted and in Windows, if I try to shutdown or restart the computer, the EXACT same issue occurs, as if I tried to sleep or hibernate the computer.

Specs:
HP EliteBook 755 G2 (EnergyStar)
Windows 7 Professional (64bit)
More: full specs here (hp.com)

I have tried:
* Installing older / newer graphics-drivers.
* Uninstalled any HP-management software which is pre-installed upon delivery.
* Disconneced all perephials.
* Deactivated all non-vital HP-management services.
* Connected mouse/keyboard to wake.
* Listened for discrepancies.
* Checked hardware for marks of burns etc.
* Checked system-log for any faults, and there is no errors which is linked to this issue.

I am at a loss of ideas on how to proceed. If you need more info, please tell me what you need and I'll provide it as fast as I can!

All help much appreciated!

Hi,

seems like I have exactly the same issues on HP Elitebook 725 G2.
I managed to mitigate it with disabling build in audio device in BIOS.
However I'm not sure if it's audio device disabled the ASPM support on the PCI bus changes accordign to HWInfo report. So might be a BIOS or Drivers issues as well. Also I noticed that issue had disappeared some time back but now is back again and I can't correlate to any changes I made.
of cause I tried all possible driver versions from HP, Realteck (audio device vendor) and AMD (chipset vendor).
I hate HP Elitebook 7XX series by now :(

let me know if my workaround works for you or you eventually found a solution.
