my problem looks like this: sometimes when i close my dm3 laptop to go to the sleep mode (sometimes it happens also when i press the sleep mode button (F3)), the screen goes black, but the computer is still running, all the LEDs are on and the touchpad on/off button doesn't work (the wireless/BT button works). After this happens, only sometimes it goes back to windows after several minutes, but usually it needs a reboot. Does anyone know where can be the problem?
I've installed new BIOS, but without change.

I have a very similar problem with my dv4 1500t (core2 duo, express 4 mobile chipset, DDR3) Laptop. It crashes every once in a while when going to standby. I tried hibernation as well. Same failure picture as described in your post. For me, I always have to switch it off to bring it back to life. If I leave it in this state for several minutes, it will eventually crash.
This is a serious issue, because you never know what will happen when you close the lid. The only thing to avoid a crash is shutting it off completely before closing the lid. And that kinda defeats the purpose of a laptop.
The problem here is that the HP customer support is really really bad. I'm not just saying that, I went through the following process over the last weeks:
I contacted e-mail support and tried everything they suggested without success. Then I sent it in for repair with the clear statement that simply switching it in and out of standby doesn't generate the fail. I also mentioned, that the failure sometimes does not show over several days. I was assured that they would look closely at the problem. Well, they received it and according to the Fedex tracking sent it back to me after only one day with no trouble found. After that, I got in touch with a case manager over the phone and the only thing they could come up with was sending it in again. I asked "what for???". Then they arranged a phone call with a senior technician. He never called.
I tried to change the DRAM on my own. That didn't fix the problem.
I guess I'm stuck with a brand new HP laptop and can never close it's lid without potentially loosing data...

All right, after a lot of experiments with installing and uninstalling drivers and running the laptop for a longer period of time in between, I found the problem.
It is the Intel PRO/Wireless Drivers for Microsoft Windows 7 update from 10-2009, Version 13.0 (or 11/19/2009 in Windows Update), which gets recommended by Windows Update, the HP driver website and the HP support assistant.
Everytime I install the update, the hangup as described above occurs after 1 - 7 days with regular use.
Rolling back the driver should do the trick, although I always used the System Restore tool to roll back to the restore point before the update.
For me, that fixes it. I'm running a Pavilion dv4t-1500 with Intel Wifi Link 1000 BGN wireless card. The last driver which works fine for me is from 7/17/2009, Version 22.214.171.124.

Hello, I hate the sleep and hibernate functions, and disable them as fast as I can.
Inevitably I'm running a program that does not "sleep" well, and my laptop is hosed up anyway.
If sleep is not what you want, I can explain how to disable it.
Heck, Click Start, type sleep, click "change when the computer sleeps".
