Dead unit that needed to be revived with T2 Recovery. Computer finally turns on, this is a brand new MacBook Pro. I reinstalled os, works, but one issue. Battery says Service Battery. The battery has one battery cycle. (So it's new and the macbook is new). It wasn't booting before until the reset from T2 DFU mode. Now it boots but the battery is not charging and yes there is no physical water damage. This is a very common issue we are seeing in these models. Any suggestions would help, before we replace the battery.

Re: MacBook Pro 16” A2141 Battery issue
I am a teacher and I have a cart of 25 A2141 Macbook Pros 16". So far 14 of them have needed battery replacement. They sat for over a year due to the lockdown, and 5 were dead when we came back, four more died this spring (plugged in), and despite being plugged in on an intermittent timer, we lost 5 more over the summer... Seems normal, right?Comment

Re: MacBook Pro 16” A2141 Battery issue
OMG.
1) Contact Apple and raise your voice on this issue. Mention that you have boatloads of their product and that you are a decision maker - they do support volume clients such as yourself - regardless of warranty status. Have seen it over and over. Speak nicely but firmly and ask to be escalated to the next level if the first one is not able to assist you.
Have many local cases including how my buddy with butter fingers dropped his rather new iPAD and cracked the display -> with a sweet sob story -> the management handed over a brand new unit. He was going into attack mode which would have led to having his tires slashed by the Apple store staff. He failed to understand - his kid dropped the unit but Apple has to replace it???
2) Batteries do have lifecycles and Apple, for the most part, should last around 500-1000 charge cycles. There is a counter inside their BMS (battery management system). Are you confident that the battery is the fault ?
What are the exact symptoms ? The unit will not charge or hold the charge ? After you replace with a fresh battery, the unit works on battery ok ?
What does the Apple battery report say? Replace the battery ?
I am sure that you are not alone on this case, do contact Apple FIRST for assistance and continue to update this thread.Comment

So I have replaced the battery. First I ordered a battery from Mobile Sentrix on our business account. Come to find out their batteries are not OEM, and after testing it had a charge but the battery would not charge when plugged into the oem 96w charger. So we assumed the battery was defective and asked them send a replacement, which they did, so they sent another one, tested that and nope same issue, battery doesn't charge. It just shows the charger plugged in and the battery status as NOT CHARGING, with 0 cycles.
So we returned that assuming well its not OEM so nevermind, so I decided... -

My question pertains to understanding the control circuity inside a Dell PT434 type battery used in Dell E6400, E6410 and other Dell notebooks?
Does anyone have a circuit diagram for the inside of a Dell PT434 battery and/or a description of how the control lines work to control this battery?
My reason for asking is I have a battery which I cannot get to charge beyond 1% in a Dell E6410 or E6400.
The LED bar graph charge indicator on the battery shows one LED lighted when the info button is pressed.
I have tried multiple different Dell power adapters. My Dell... -
Hi everyone,
I'm having an issue with my Lenovo ThinkPad P43s. The laptop does not power on when the internal battery is connected, but it works fine on AC power alone (battery disconnected). Once the battery is reconnected, the system becomes completely unresponsive — no lights, no fan spin, nothing.
Here's what I've tried so far:- Power/EC reset (held power button for 60 seconds with battery and AC disconnected)
- Booted successfully on AC power only with the battery disconnected
- Visual inspection of the battery — no swelling, burn marks, or connector damage

Hi, so the old battery was getting error stated it's capacity is starting too get low and should be replaced, so the customer bought a new one and replaced it, but the new battery was also getting this notice that it's capacity is getting low and should be replaced, so i took the laptop for testing and the battery is charging at the terminal at 8.03V , the voltage of the battery is 7.7V, and drawing around 600mA when charger is put and the laptop is off...so that should be ok... but the bios system test doesn't recognize the battery and can't do the battery test and so is the hp battery manager,...
