Hi all,

My older MBP that I use more than my new one doesn't seem to keep time. If I close the lid then come back to it, it sticks at the time I closed the lid. For example I closed the lid at 15:57, just opened it and it stayed at that time when it is in fact 17:29.

The only way for me to get the right time is either turn off the wifi then turn it back on again or go into settings, time and turn it from auto and back on.

The first time it did this was when I had been away and it had died for a while - the only way to get it to the right time was in terminal and putting in some prompts I'd seen on the apple website.

The laptop is a 13-inch, 2020. 1.4 GHz Quad-Core Intel Core i5. Intel Iris Plus Graphics 645 1536 MB. Intel Iris Plus Graphics 645 1536 MB.

Just wondered if anyone has any ideas as to the root cause? Any help would be great. Thank you!

Thanks,
B.
 
Might be the CMOS battery/capacitor but they usually last like 10-20 years+ what happens if you don't use AUTO time and just manually set it?
