  • I just had the same issue. Optiplex 755. Anyone in the Dell community able to shed some light on this?

    We would certainly appreciate it.

    TIA,

  • I've got an Optiplex 755 exhibiting the same behavior.  Received a warning "System Battery Voltage Low".. so I replaced the motherboard battery (CR2032 3.volts) and on next reboot received the same error damtrung_hp noted (above). Upon trying to boot the system, Windows XP is now BSOD'ing. ;(   ... Going to test the hard drive in another 755,.. assuming that works, I'm not sure what else to do besides submit this unit for a motherboard replacement. (because I'm not finding any software download tools to reset the system management hardware)

  • CHKDSK found no errors on the drive. Pulled hard-drive and tested it in another 755... everything booted fine. Going to submit system for motherboard replacement.

  • I experienced the same string of events. CMOS battery died. Replaced with new battery. Got the same message at boot up.

    "The system management hardware requires a reset.System setup configuration and the date/time require attention after the reset.
    Strike the F1 key to continue,F2 to run the setup utility
    Press F5 to run onboard diagnostics
    "

    Resolution:  I found that if I entered the asset tag into the BIOS and saved it, the message went away and system returned to normal.

  • I have tried different and it did work!!,

    following explains how to reset system management hardware

    Press Ctrl-P while booting up

    Management Engine will open

    use 'admin' as password

    you are required to setup a new p/w, do it.

    it will prompt and say if you do it will reset, thats what we needs!

    then exit,

    once restarts, error message disappears!! now you can install os as usual. 

  • Una consulta , yo escribo cualquier contraseña y me muestra mensaje "error intel me password change rejected" , hay algun ejemplo de contraseña que puedo agregar.

    te antemano agradesco tu respuesta prontamente.

  • abra alguna solución para este problema , intente con todos los resultados  que hay en este post. pero no se arregla el problema. o simplemente ya se daño la placa....???

    "El hardware de administración del sistema requiere una configuración setup reset.System y la fecha / hora requieren atención después del Reset.

    Presione la tecla F1 para continuar, F2 para ejecutar la utilidad de configuración

    Presione F5 para ejecutar el diagnóstico a bordo "

    favor de responder si, encontraron alguna solución certera...!!!

  • I tried this but using "admin" for password did not work for me. What do I do know? Please help!

  • This worked for me thanks.

  • Hello, I've tried this fix but every dumb password I put in says it's rejected.  I'm able to use the "admin" one to get into the management screen but it won't let me change the password.  Can you tell me what you used or a version of it?  Or do you know the password requirements?  Thanks!!  Ron
