Laptop missing clock and date sync at start up

[adavalos]

At start up I receive error 601, I changed the internal battery and the error is still there, the laptop starts up normally but the clock and date are incorrect every time I turn on the laptop, this is creating issus with the anti-virus settings, google chrome and more. I need to manually sync the date and clock using the "Internet Time" sync option. This is my laptop information

I followed up the procedure and error is still there, anything  else I can do?

[visruth]

Did you get new RTC battery and replace old one?

[adavalos]

Yes, it was a new one

Can you use a "multimeter" (such as an electrician would use) to measure both the AMPERAGE and VOLTAGE values for both the "old" and "new" batteries?  Values?

[adavalos]

both old and new has 2.8 V, the old battery has lower amps than the new one but the amps are not kept constanst, but the old one is falling faster than the new one.

I just install another new battery and the result is still the same "error 601", I'm affraid that the battery is ok and something else is wrong in the hardware, I hope not

> anything  else I can do?

Yes, see: http://noosphere.princeton.edu/time.regedit.html

Read the paragraph about "CurrentControlSet" -- update within that registry-branch.

You can set your computer to synchronize with a time-server much more frequently than the default "once-a-week" (expressed in seconds per week).

How often do you reboot your computer?
