Woohoo!!. I’ve been having this problem ever since I’ve had my latest laptop: The computer occasionally does not hibernate and you receive an “Insufficient System Resources Exist to Complete the API” error message in Windows XP with Service Pack 2, in Windows XP Tablet PC Edition 2005, or in Windows XP Media Center Edition 2005.
Apparently, the problem is caused by the fact that the Windows kernel power manager doesn’t manage to find a block of contiguous memory to hibernate. This happens occasionally on laptops with 2Gb of RAM. It can be quite annoying when you put your laptop to sleep, pop it in your haversack, then some time later find a discharged battery and a VERY HOT laptop bag (my laptop uses a 180W PSU, just to give you an idea of how much power it sucks up).
Anyway, it’s nice that they solved the problem, HOWEVER, you can’t actually download the hotfix, but have to contact Product Support Services for it. I’m not sure if there’s a fee to be paid for it, so I just Googled the hotfix and found a copy elsewhere.
Here’s a copy if anyone wants it: Download here: WindowsXP-KB909095-x86-ENU.exe
