My MacBook keeps beeping every 25 seconds.

You can check on your battery anytime by clicking the apple in the left corner of the menu bar, About This Mac, More Info, System Report, Hardware, Power and see what it says about Charge Remaining, Capacity, battery Condition, Cycle count. The condition should always be Normal unless there is a problem. The ratio of the charge remaining to the capacity should be the same as the percentage charge indicated on the right end of the menu bar, allowing for roundoff. Most Lithium-Ion batteries have a cycle life of 1,000 cycles, but the cycle life doesn't necessarily mean it will fail at that point, just that the capacity is less than 80% of the as-built capacity.

You can try an SMC Reset, but regular beeps often mean a memory problem...did you install memory yourself in your MBP? If so, check to see it is seated properly. If not, visit the Apple store genius bar and have it checked by the techs.

Not a waste of time, good to here the problem wasn't the MBP itself, well other than a low battery 😀

Even though you didn't ask, a good way to treat the battery is to only discharge to 50% before recharging, deep discharging regularly to shtudown is actually not good for Lithium-Ion batteries. The best balance for use/charge/cycle life seems to be in the neighborhood of 50% cycling...gives about 4 to 5 times the cycle life of a battery regularly fully discharged.

You can leave the MBP plugged in, the charging circuit senses when the battery is fully charged and shuts off, then when the battery drops below 95-93% charge, restarts and tops off the battery, and keeps following that pattern. Best advice is unplug once a month and discharge to 50% then recharge. Follow that pattern if you like for a longer cycle-life for the battery.

You are welcome.

The MBP will not overcharge the battery. You may leave it plugged in.

Ciao.

You are welcome and good luck.

Ralph Landry 1, greeting; Nuts. Forgot about that. Well done.

Hi OG, we all forget stuff around here...unless you are one of the few that has created a set of canned responses for all kinds of questions and then just drops them in 😀
