Mid-2015 MBP Not Charging Normally

Since the battery was replaced almost 1.5 to 2 years ago, there is no longer any warranty on it. While 2 years is a short time, sometimes a battery will fail a bit early. Unfortunately it is hard to say if the battery is bad at this point since the DC-In Board or even the Logic Board could be the source of the problem. Make sure to disconnect all external devices in case one of them is causing a problem. I would also look closely at the contacts on the Thunderbolt ports to make sure they are not showing any corrosion or scorch marks....they could easily interfere with the system. Here is an Apple article for troubleshooting Magsafe charging issues:

If your MagSafe cable or power adapter isn't working - Apple Support

I would examine the Magsafe connector on the laptop looking to see if the contacts are clean and making sure there are no small thin bits of metal stuck onto the magnet of the port. Staples or something similar also tend to get stuck there, sometimes pushed up against the inside edge where they may be hard to see. If the power adapter is not seating completely, it may sense the power adapter, but not charge the laptop. Many times even a clean port still requires me to fidget with the Magsafe connection to get a good connection.

Also examine the pins of the original power adapter to make sure none of them show any burn or scorch marks...if they do, maybe it damaged something on the laptop.

You can take the laptop to the Apple Store or another AASP if available to have the laptop evaluated, but the laptop is now considered "Vintage" so repairs may no longer be possible.....it will depend on the availability of parts.

Of course the battery may actually be bad as the diagnostic reports since the last error you listed (PPT004) seems to be a stronger indicator of an actual battery issue.... the other could be anything interfering with charging.

FYI, if you can boot macOS normally, then you can use the following command to get battery information (not sure if it is available in Recovery Mode since that mode is very limited):

pmset  -g  rawbatt

Same as previous command, but will print new report once every minute until terminated by pressing Control + C:

pmset  -g  rawlog

This gives some basic battery information....sometimes even showing a battery failed message which I believe is being pulled directly from the battery itself, but I've only seen that occur a few times (there is a possibility the previous commands may show it as well, but I am not certain):

pmset  -g  batt

FYI, this only works on Intel Macs. Unfortunately when used on Apple Silicon Macs, the information displayed is slightly different and not as useful.

I have a Mid-2015 15” MacBook Pro (DG). In early 2022, I had an Apple Authorized Service Provider replace a swollen battery. At that time, I did not additionally replace the power adapter, even though the cable from the MagSafe to the power brick appeared a discolored yellow and stiff. Shortly after getting the battery replaced, I bought an external monitor and left it connected to the MBP 99.9% of the time. Sixteen months later, this laptop suddenly would not take a charge even though I followed the technician’s instructions of letting the battery discharge every month or so. However, running Coconut Battery close to a week after it did not take a charge, it showed 100% design capacity as shown below.

Hence, I ordered a new Apple MagSafe 2 power adapter (genuine) from OWC — it would not charge.  Then, I tried resettling the SMC and PRAM several times — it would not charge.

Doing a diagnostic test, I get the following errors:

PPP003

There battery might not be charging correctly

PPT004

The battery requires service. The battery is not functioning normally, though you might not notice a change in its behavior or the amount of charge it holds. You can continue to use your battery before it’s checked without harming your computer.

During all this time since it first would not take a charge, I rarely disconnect the new power adapter from the laptop.  When I do and reconnect the power adapter, the computer instantly powers on.  I leave this MBP powered off most of the time, while I currently use a slightly older MBP in the meantime.

The technician who serviced this laptop is no longer with us and the shop closed its doors.

Is there any other probable solution I can try to make it take a charge before trying to have it serviced?

Is it worth having it serviced a second time if I intend for it to be my daily driver once again, or am I better off getting a new laptop or desktop as a replacement?

Thank you!

If you reset the SMC Reset the SMC of your Mac - Apple Support several time and no resolve...

I would take it back and let them sort it out if you paid for the replacement, typically there is a 90 warranty for parts & labor
