RMBP battery damaged?

[Geforce3]

Hi all,

I currently own a RMBP 13" early 2013 edition.

Recently I noticed that my MDP will auto shutdown once the battery is left with about 30%.

I checked the system report and the battery is reported as fine and the cycle count is currently at 257.

Anyway, I took a screenshot of the report:

Should I send it in for a service just to see what is wrong? Or should I try re-calibrating my battery first?

Do a PRAM and SMC reset.
Then calibrate your battery.
and see if it repeats.
If it does, do not bring it down to the service centre.
Call up AppleCare first (this step is important, because our AASPs have really terrible customer service)
then after you have a case ID. Head down.

will calibrate it tmrw, just did the PRAM and SMC reset

Yes SMC reset will the first step in troubleshooting power-related issues.
Did you get any message after the computer restarted? like a kernel panic message or something?

If it does happen again, open up Console on next boot and paste the log during the period it auto shutdown here.

Same thing happened again. MB just died at 29-30% and when I charge it to turn it on, the clock is reset to 8a and the date is all wrong.

I think I should really call apple support first

You may also want to run Apple Diagnostics prior to the call. The results may help the AppleCare advisor in providing you a solution.

i think e batt is kaput but like what asriznet suggested u might want to try a diagnostics to check.

if time and date is wrong, quite likely that the logic board battery has run out. not a very expensive job but needs AASP to assess and replace nonetheless

The MacBook Pro retina do not have a CMOS battery installed on the logic board.
Only older models of MBP/MBA have a CMOS a battery.

The functionality is built into the main battery itself so very high chance your battery needs replacement if a MacBook does not retain PRAM settings after reboot.

Reason for this change: I don't see why a portable computer needs a CMOS battery when there's always a power source(battery). For a desktop, it's understandable as user might turn off the main power so it needs a backup battery to retain the PRAM settings.

Diagnostic boh taichi leh zzz.

hmm retina pro models I think some of e batt cells r glued to e casing. some more is not 1 big cell. is several small cells. gonna be hard to troubleshoot.

ok what happens is at around 29% 30%, the mac just dies. It shut downs and doesn't go into sleep. There is no warning etc.

When I use the adapter, the mac doesn't come alive automatically, I have to press the power button and the dates and time are all reset to the default.

It's only on the 2nd reboot with wifi that the date and time are changed to reflect the current time

Because the issue cannot be replicated anytime you want, AppleCare Advisor cannot provide a direct solution at time of call. All they can do over the phone is running through the Apple Diagnostic Tool and check Console logs for any hints of any.

If all above returns no results, they will most likely refer you to an AASP for further hardware diagnostics.

In the AASP, the AST test will run a quick check to make sure the communication to all the components is running properly. However based on your symptom, they may need to take in your macbook to run the ASD(stress test) until the issue replicated to identify the failing part.

yeah making it more harder to self diagnose and repair.

That's 1 reason I'm still sticking to a non-retina model for now...

But for troubleshooting the battery, nothing much to do other than disconnecting and reconnecting the connector which don't require removal of the battery.

Called Applecare, got case id, going to AASP.

 

[Geforce3]

Sent it in for servicing. Hopefully all goes well.

got my mac back, they didn't do much. Seems like they couldn't repeat the problem. but they changed the battery and the top plate

Well at least the went ahead with a force replacement of the battery despite not being able to replicate the problem.

Hopefully that was the issue and not the logic board else you will see them again not too long from now.

Hopefully, but when I collected my mac it was about 28% battery and it was fine so shrugs
