3. Do I need to unplug my laptop once it reaches full charge?
No, you don’t need to unplug your laptop once it reaches full charge. Leaving the charger cable plugged in your laptop won’t “overcharge” or harm the laptop’s battery life.
I can tell this from my own experience of having seen thousands of computers that need repairs.
I myself have always preferred plugging the charger in whenever I can. While my wife has always used her laptop on battery. Both of our laptops have lasted for well over 8 years!
So, you don’t have to worry about leaving your laptop to charge overnight. You can just leave the charger in while you use it, while you’re not using it, anytime really.
The lithium-ion batteries on modern laptops are made with a mechanism that is designed to stop charging the battery once it reaches full charge.
This avoids the accidents that may happen if the battery keeps charging and starts to heat up. If you click on the battery icon on your laptop, you should see it indicating “plugged in, charging” or “plugged in, fully charged”.
If you’re concerned about battery life deteriorating, that shouldn’t be a big problem with lithium-ion batteries. Lithium-ion batteries are also made to be able to be recharged over and over again, without losing their power capacity.
You could charge your laptop hundreds of times and that wouldn’t change its average battery life and performance. Of course, after about 600 charging cycles or more, the battery could lose its performance and start to fail. Then you’ll need to replace it.
4. What does “service battery” on my MacBook mean?
Apple MacBook laptops have different battery status indicators that tell users about their batteries and when it needs to be serviced. This includes “service battery”, “replace soon”, or “replace now”. Newer Macs may just show “service recommended”.
“Service battery” means that the battery may be holding less charge or isn’t working as well as when it was new. The battery is still working and can be charged up and used, but will need a little attention soon. You might want to take it to the Apple Store for some TLC.
As we’ve mentioned above, a high charging cycle count means that the battery may be on its way out soon. You can check your cycle count on your Mac, from “System Information”. Go to Hardware > Power, then you’ll be able to see “Battery information”.
There you can find information like your laptop’s full charge capacity and cycle count. You can only look up the maximum cycle count for your Mac model from Apple Support.
Although a high charging cycle count should be something to be aware of, it’s not the only cause of laptop battery failure. Even a battery with a low cycle count can fail. Along with the performance of the battery, the way the battery’s been used, and the overall performance of the laptop can cause battery failure.
5. Should I use a surge protector?
Yes, you should!
A surge protector can protect your laptop from getting fried by a current gone awry. When a power surge happens, the current is redirected to other sockets and can pass into your laptop through the charger.
This can do all sorts of damage, including burning the motherboard or frying the battery.
However, don’t assume that a power board with surge protector will prevent power spike from damaging your computers completely. It helps, but it’s not 100% protection.
Uninterruptible Power Supply (UPS) is a much better power surge protector for your computers.
If your computer is critically important for your business, you should consider getting a UPS. Many businesses have UPS for their main computers, printers.
