Standby does not work since I installed the latest XP SP3. When the 1230 goes into standby, the screen goes blank and the keyboard is locked. It will not quickly resume with an active screen regardless of which key is depressed. In order to recover, the power must be turned off, and then back on in order to continue. In effect, standby works like hibernate, even though hibernate is not enabled. Any ideas about the cause of this type of problem? Does the BIOS have to be updated??
