Eprime Alert (for more info go to https://support.pstnet.com/hc/en-us)
Windows 11 laptops may exhibit timing issues where the OnsetTime is delayed and the OnsetTime value is inaccurately assigned and logged. Typically, this issue only occurs while on battery power. This delay period typically lasts a few milliseconds, but can be greater than a refresh, and does not occur on every trial.
Workaround 1:
Plug the machine into line power and do not run on battery power.
Workaround 2:
Change the computer's Power Mode setting. We observed these issues when using "Balanced" or "Recommended" settings. To check this setting and change if needed, open the System Settings (i.e., press Windows key + I), select Power & battery, and change the setting from "Balanced" or "Recommended" to a "Best Performance" mode (the specific Performance setting name may vary with specific Windows versions).
