Recently,
Worldstart ran a tip on laptops concerning the dangers of keeping
them plugged in for too long. Corrections are in order, I feel, and
although some of the information found in the article holds true,
I'd like to take the time to explain a key point with more
detail.
On the topic of batteries exploding or being ruined form being
plugged in too long.
Don't break out the bomb suit just yet. While there has been cases
in the past of laptop batteries exploding in the past, this was put
down to faulty hardware and not overcharging. Most, if not all
modern laptops can be left plugged in for as long as you like with
no danger of combusting.
As far as ruining your battery from overcharging. Most modern
laptops will stop the charging process once the battery is full and
switch over to a plugged in state where the battery no longer
continues to charge. Once again, this is a feature of modern
hardware, so if you have an older system you might want to check
the manufacturers website to see if the model you're using is in
any danger from staying plugged in.
Hope this helps!
