Hope this helps and do let us know if you need any assistance.

There is possibility that the system hangs on suspend and then eventually crashes with 9F.  Check your %SystemRoot%\Minidump folder to see if there is a memory.dmp file.  If there is one, upload it to your skydrive and share the link.

Hi,

I am facing similar issues and tried all the mentioned things in the forum. I have a HP Pavillion n003tx. I have pasted the link to the dump files. Please help.

Yeah my laptop (HP4740s) isn't waking up from sleep either. So I have checked my minidump folder and I am having a couple created every time I try to put the laptop to sleep.

This is not really an answer but wanted to check if you have all the updates on your system.

If not, could you run windows update and make sure that you have all the updates?

Thanks.
