I have been asked if there is a secure hibernation option in the later versions of EEPC. We are currently using version 5.1.9 on most machines and have not allowed the machines to hibernate.
What do you mean by "secure hibernation"? When machine hibernates, it powers off. You will get normal EEPC pre-boot before Windows starts up and uses hibernation memory dump.
When we first starting implementing the Safeboot encryption, either there was not a secure option for the hibernation OR I was told there was not when I took over this support. I have tested this with my laptop and it works fine, but when I tried it on another laptop, it got a blue screen when trying to start back up. It had some error about trying to write paged data to a non-paged area.
I will continue to invesitigate, but wonder if you have seen something similar to this before.
Just to make sure we're comparing apples-to-apples: when you say "Hibernation" do you mean "Hibernation" by the Windows definition, or do you mean "Sleep" or "Stand-By"? Not trying to insult your intelligence but I've found people often seem to use these terms interchangeably. With regard to drive encryption the distinction matters quite a bit.
sleep, hibernate, low power, any and all have been supported for half a decade or so ;-)
You're right about the loose interpretation though. I mean stuff stored in hiberfile.sys and battery out, supported - yes.
From a "supported" perspective, yes I understand. In terms of understanding what the poster's question here is though it's important. If he/she is truly asking, "is hibernation secured by EEPC?" Yes. But if they are intending to ask, "is there a secure Standby option...?" No. No there isn't. Supported, yes, but the encryption is still unlocked when in Standby. Has nothing to do with the EE product. Maybe Microsoft should call it "Extremely Low Power Mode" since the machine isn't actually off in this mode. But that would never get past marketing... Mostly want to be sure we're helping to answer the right question here since the terms are so freely tossed around.
Thank you for the comments. I am speaking of "Hibernate" as defined by Windows. In addition to this, I have not seen the error again where it would not resume into Windows, but I have seen that the wireless driver seems to be disabled when it comes back up. Any ideas on that?
This is really unlikely to be related to EEPC. I'd take a look at: http://support.microsoft.com/default.aspx?scid=kb;en-us;885293 if you're running XP SP2 or earlier. Maybe update your wireless driver. Good luck!
