What is forced ePSA?
Dell Latitude laptop PCs have a recovery feature called forced ePSA. Forced ePSA can attempt to recover a Dell Latitude laptop PC from a POST or a boot failure so that additional troubleshooting may be attempted if required. Forced ePSA can help recover a Dell Latitude laptop PC in the following scenarios:
- POST failure: The PC may show signs of power but will not display the Dell logo after powering on. Caps Lock LED indicator may not illuminate when toggled using the Caps Lock key. LCD screen (LCD display) may appear blank or black after powering on the PC.
- Boot failure: The PC may display the Dell logo after powering on but will not boot into the operating system. This includes failure to boot completely or stalls while booting into the operating system.
Note: Forced ePSA is currently available only on Dell Latitude laptop PCs.
