My new work computer (Dell Precision T3600, 16GB RAM, SSD) running Windows 7 takes roughly 40 seconds to wake up from sleep mode.
How can I diagnose what's taking so long? And what can I do to reduce the time?
You should install the Windows Performance Toolkit run xbootmgr to see why Windows is slow to resume from sleep. Generate the XML, and look at the resume nodes. if you're unsure, upload the ETL file, I'll take a look at it.
