Uncertainty about whether the battery or charger is the issue with your MacBook Pro 15.
The MacBook Pro (MJLQ2LL/A) stopped working properly after a sudden battery drain. It seems the battery cycles have reached their limit, around 100. When you try to charge it, the charger lights up orange and the device powers on briefly before shutting off. Without the charger, it shows a red battery icon and needs charging. Your concern is whether the battery is damaged—if it didn’t show at all, it’s likely faulty. You’re considering replacing the battery or trying a different charger. Since you don’t have warranty coverage and want to avoid unnecessary costs, checking if the charger itself might be faulty would be wise. If you confirm the charger is reliable, you could try using one; otherwise, replacing the battery seems safer. Look for affordable yet dependable chargers online or at local stores.
The laptop should be at least four years and no more than seven years old. Replace the battery if necessary. If that doesn’t work, try using the charger. If neither option is viable, the charging system might require repair.
I begin with the charger. If the battery is faulty, you’re less likely to notice the screen indicating low power. You can check if you can borrow one from someone else before buying a replacement, or visit an Apple store to see if they’ll offer a different charger. If you must purchase a new one, opt for an authentic Apple charger. Yes, they cost more, but it’s better to protect your device than risk damaging it with a cheaper option.
