Inspiron 545S error code 4c00:021e

HI,

I ran the embedded Dell Diagnostic on a Inspiron 545S after replacing the power supply.

I got a RTC Functionality Test error code 4c00:021e.

The error message is "The time registers did not increment correctly. The RTC did
not generate the expected time after it was set for the maximum value and
allowed to roll-over."

How can I fix it other than replace the motherboard?

    I would at a minimum replace the DL2032/CR2032 battery.

    Most Grocery Stores, Radio Shack, *** etc have these batteries.

Ensure that the object is inserted between the battery and the socket before you attempt to pry out the battery. Otherwise, you may damage the system board by prying off the socket or by breaking circuit traces on the system board.

    Good advice SpeedStep.

    I'll give it a try later this evening.

    I'll keep you posted.

    Thanks.

    Hello SpeedStep,

    I had left the PC unpowered (power chord removed) for the entire day.

    Before changing the battery, I wanted to check if I still had the error.

    So I powered it back on and reran the RTC test.

    It passed this time.

    I don't know if draining the residual power for the entire day did the trick, but the PC is all OK.

    Thanks a lot for your help.
