I have a macbook pro 16 inch from 2019. Recently I have been experiencing the issue that when my macbook is fully shut down in my bag, after a few days its battery will be 0%. The battery condition is still normal (less than 150 charges). I only use my laptop every few days/weeks.
I deem that the issue is that my macbook powers on likely due to pressing a key/trackpad while inside my bag. It's a pretty tight bag with equipment and I also see the black roundings from around the screen (on the grey part surrounding the keyboard) when opening the lit.
I have already disabled autoboot when opening the lit. But the issue is really that the macbook turns it due to a key/trackpad getting pressure when inside the bag. I have also checked all other battery settings that the macbook would not turn on by searching for wifi, bluetooth etc. (all relevant settings turned off)
Please can someone help me to fix this issue? Any support would be highly appreciated. Thanks in advance.
The battery may be 6-7 years old. Even though it shows as "condition normal" and has had relatively few cycles, batteries wear out over time whether used or not. If it is connected to a charger all the time, that can also stress a battery, unless you are using Apple's automatic battery health management.
I have the same laptop model as yours. This model turns on automatically if or when the lid lifts even slightly from the keyboard/pad. What might cause this to happen? One possibility is that the battery is swelling slightly and keeps the lid from closely securely, or pushes the lid even a tiny amount, thus triggering the automatic power on. This in turn could result in the battery fully discharging over some hours or a day or so. This can be v ery damaging to batteries, and thus worsen this behavior.
A battery can start to swell slightly when it has aged and is starting to fail. This can in fact be dangerous because such lithium batteries can leak damaging fluids and chemicals or even spontaneously burst into flame. A swelling battery can also severely damage other parts of the computer.
To see if this is happening, scrutinize the track pad under a strong light. Does it look perfectly even all around its border? Are any sections or corners higher or lower than others? Place the laptop on a very flat surface. Does it sit perfectly flat and even when viewed from all sides? Does it "rock" a little back and forth, even very slightly? When you shine a strong light under the laptop, does it look similar from all four edges? When you close the lid, does it close evenly and look flat and well sealed from all four viewing vantage points?
If the laptop is being distorted even slightly by the battery, this is the cause because it can result in the laptop not closing fully and thus powering on unexpectedly, or it can result in keys pushing up and being depressed by the screen, which would also power on the laptop. And it means your battery must be replaced. An Apple Authorized Service Provider (these are listed on Apple's web site) can probably do this for a moderate fee. I would not undertake that battery replacement myself. It may be challenging to find a new battery to replace the old one with. AASPs know where to obtain these parts.
