Thanks for your reply.

At that time I did manage to get Hauppauge to exchange cards that were exhibiting the problem a couple of times. I ended up buying used cards on Ebay and running sleep/wakeup cycles repeatedly till I had working cards.
Hauppauge support told me the never heard of an issue like this. You are the third person I'm aware of to report this specific issue to Hauppauge support.
Seems that their knowlegdebase has some flaws..!

The rev of the card as reported in Device Manager needs to be newer
than 88000 to avoid the losing the card on wake problem.
Cards marked 88041 report as 88000 and often don't return from sleep
Cards marked 88061 report as 88051 and may work in x1 slot
My card is marked as 88061 LF and reports as 88051 in device manager.
After reading your post, I pulled the card from the x1 slot and put it in the first x16 slot. The following then happened :
1) Upon restarting windows, Windows installed the following drivers :
Hauppauge WinTV HVR-2250 (8851)
Xeon(R) processor E3-1200 v2/3rg Gen Core processor PCI Express Root Port - 0151
(Why the latter one installed *only* at that moment remains a mystery to me..)
2) The sleep function worked properly on all times !
3) After putting the card back on the x1 slot, the sleep disorder problems came back.
4) I then put the card in the 2nd x16 slot (*) : sleep disorders persists !
(*) Depending on the HP datasheet you read, the second x16 slot is sometimes identified as an x4 slot. In my system, the BIOS "Slot Security" option lists it as an PCIe-x4 slot.
5) I finally put the card back in the first x16 slot : sleep works as expected !!

An alternative you could investigate is that Hauppauge now has a USB dual tuner that may exhibit better sleep/wakeup behavior but I have not tried one out.
Given the poor support (or lack thereof) I got from Hauppauge, I doubt I will ever buy another device from them. Known issues or incompatibilities (with workarounds, if any) should be listed on their support web pages and they should be more proactive in helping troubleshoot the issue, just as you did !!
Thanks again for your input !!
