Sorry, I haven't checked back here in a while since I almost already gave up hope ;-)
Thanks so much for all your suggestions/advice! I will check if it works for me and post back here...
PS: and no, after a first "not-helpful-at-all" support from hp with my first new pc (which then I simply exchanged in the shop after two weeks) I did not think contacting hp support would solve my problem. Generally forums seem to be a far better place than any support hotline - thanks to all you big and little helpers...

I have a HP HDX X16T-1200 notebook that also wont stay in either sleep or hibernation mode after setting it go into that state when closing the lid. When I'm done for the day, I'll close the lid and it does go to sleep. The HP logo light also turns off on the lid when in sleep mode. In the morning, I'll see the HP logo light back on and it is not in sleep mode when I open it up. If I'm lucky and the power brick was plugged in, all is well. But if I don't have the power brick plugged in, the battery is dead. I can't seem to make this computer conserve energy other than a full shut down.
I looked at the Device Manager and both Network Adaptors (Intel WiFi Link 5100 AGN, and Realtek PCIe GBE Controller) do not have the "Allow this device to wake up the computer" box checked. What else could be waking up the computer?

I have a similar problem with a Realtek sound card causing immediate rewake. I have spent hours on the net trying to get a solution.
Following the advice from TechiZone, there is no Power Management tab on the sound card. I have also used Powercfg to no avail. Any help would be very gratefully received.

It's not your sound card, check the ethernet or wireless adapters in Device Manager they should have the power management option.
If a device doesn't have the Power Management tab listed that it doesn't support those power management feature and it's not something to worry about it since it's not causing standby/sleep issues.

Thanks for your incredibly quick reply - I've been away for a couple of days so could not respond. The reason I blamed the sound card was because one forum said that the command powercfg/requests would show the culprit.
However, since your reply, I went to Device Manger and checked EVERY item looking for a Power Management tab.
The wireless LAN card has a "wake" option that is greyed out and unavailable, the Realtek PCIe GBE Family Controller has a "wake" option that does not make any difference. What really surprised me was that when EVERY Power Management was set to Off, it worked alright and when I allowed wake one-by-one, i discovered two culprits - the mouse and the keyboard!! They are the ones supplied about two weeks ago with the PC, a p6-2022uk from HP. Subject to further extensive testing, it would appear that leaving "wake" ticked on the Realtek audio and Realtek Controller makes no difference, but my problem is solved if I disable wake on keyboard and mouse.
Sorry about the long and rambling reply.
