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... -
Hello everyone,
Mark and model: ASUS X571
Symptoms: not turning on. There is only the LED battery indicator working. The owner of the laptop told me this problem arrived one week after having changed the battery. He then managed to power on the laptop only once, and then it never powered on again.
Tests already made:
- Battery is charging when laptop is plugged in. The LED battery indicator turns white after a couple of hours of charge, indicating that battery is fully charged. However, laptop won't turn on anyway, with or without AC plug.
- I have removed... -
Hello. Sorry for the long post, but I am trying to decide if this is a simple battery replacement, or potentially something more complicated.
I bought an open box MacBook Air M1 2020 A2337. Seller claimed it was never used. Visually, it appears pristine.
On arrival, the battery was completely flat. Computer powers up and boots fine. Battery status showing 1% and charging, 1 cycle. coconutBattery showing 0 mAh and ~6 watts.
After some hours, the battery status did not improve. Restore via DFU did not help.
I connected the power adapter to a Kill-a-Watt... -

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...
