Real time clock error and System timer error - please help

Question

Hi all

My clock does not update, and when running a diagnostics I get the following 2 error codes:

Real time clock error code 4C00:021D

System timer error code 4C00:041B "channel 0 (mode 3) is generating the wrong interrups count per second. Expeced 18. Actual 39.

Any suggestions? Your input is most appreciated.

Both of those errors are tied to a bad realtime clock chip - not the battery (or CMOS battery). Having that chip replaced will solve both - you will need a shop that can do board-level soldering (not a typical parts-swapper like Geek Squad, EasyTech,etc., which will simply tell you they must replace the system board.

Expect a clock chip replacement to run $150-200, part and labor (about 1/3 the cost of a replacement mainboard).

By the way. In my hardware I have a PCI device that is not working properly. But I can not figure out how to find the relevant driver, because the device is presented as unknow. My laptop is a Dell M1730. Could that be the root of the probelm with my real time clock?

The real-time clock chip needs to be replaced - which requires a soldered mainboard repair (or replacement of the mainboard).

Thanks ejn63. Any chance of it only being the battery that needs replacement?

Thanks ejn63. Any chance of it only being the battery that needs replacement? Will the possible change of chip cover both errors?
