At some point in your laptop's life, the battery will stop holding a decent charge and you'll be plugging it in every few hours.
It's inevitable – even if you buy a laptop tomorrow – the battery on it will eventually start to hold a charge for less and less time.
It won't happen instantly, but eventually you'll wonder if you even need the battery to use your laptop when it's plugged in.
Good news. You probably don't.
People are starting to favor laptops as their personal computer instead of the much larger desktop computer – and they leave their laptops permanently placed on a desk or counter.
There are a few things you should know before you yank the battery and retire the portable side of your laptop.
Use The Original Power Supply
If you're going to be leaving your laptop plugged into your outlet full-time, be sure you're using an original power supply.
Laptops are sensitive to electricity fluctuations and it can easily damage the internal components. An original power supply is less likely to fail and cause a problem over a long period of time.
Use A Surge Protector
You can pick up a surge protector power strip almost anywhere. This will stop any spikes in power that would have been sent to your laptop. A strong power surge can completely kill your laptop to the point where it will need to be replaced.
Shut Down Then Unplug
When you're using your laptop without a battery, be sure not to disconnect it from the outlet until you've shut it down properly.
Get A Back Up Power Supply
You can go even further and protect your laptop from power issues by using a backup power supply – or sometimes called an uninterrupted power supply (UPS).
This will detect a power outage and supply your laptop with power until your power gets restored. They won't be able to power your laptop forever, but it will be several hours. This will give you enough time to save and shut down your laptop properly and avoid damaging it.
Protecting A Good Battery
Maybe you have a good laptop that runs great on battery and you'd like to protect the battery and keep it's capacity in good shape.
If your laptop allows it, removing the battery will help extend it's life – by how much is up for debate.
A lithium-ion battery will deplete at about 5% per month, so if you charge the battery to about 60% and then remove it, you'll have a battery in good shape when you need it next.
There's a myth that batteries should be stored in a fridge to prolong their life – but that's only in extreme heat.
Plug In Or Battery Every Day?
I use my laptop daily – i'm writing this post on it right now – and i charge the battery to 100%, then disconnect from the outlet and allow the battery to run down.
Some times I run it down to 10%, other times I run it down to 40%.
I know the battery run time will get shorter and shorter – i'll just have a new one installed when that time comes – in a few years I expect.
I think the most important thing is that you just use your laptop and be productive and creative.
Is There A Program To Disable Battery Power?
I thought this was a cool idea.
Instead of having to remove your laptop battery, why not just instruct your laptop to avoid charging the battery and connect directly to the outlet power?
I haven't seen any software that does this and i'd expect it would have to come from the laptop manufacturer and be pre-installed on any laptop.
Maybe we'll see that some time?
Can You Overcharge The Battery?
Almost all laptops have a smart charger that will discontinue power once the battery reaches 100%.
You shouldn't have to worry about overcharging or damaging the battery, just be sure to use an original charger.
