Cold Boot issue on Symbol VC5090 FLT Terminals

You can manually change the power setting to stop this behavior. The best thing to do would be to create a .reg file out of the following keys....

[HKEY_CURRENT_USER\CONTROLPANEL\DEVICES\CDL1:]
"TIMEOUTWAKEUPFLAG" = DWORD:00000000
"POWERKEYWAKEUPFLAG" = DWORD:00000000
[HKEY_CURRENT_USER\CONTROLPANEL\DEVICES\CDL2:]
"TIMEOUTWAKEUPFLAG" = DWORD:00000000
"APIWAKEUPFLAG" = DWORD:00000000
"POWERKEYWAKEUPFLAG" = DWORD:00000000

...and then copy that reg file onto a terminals \Application directory.
Then make the terminal cold boot, which will merge these reg keys and the terminal should be set so that if you suspend using the power button, remove power and then replace power, press the power button again the terminal should resume where it left off.
