Remove Your Laptop Battery To Make It Last Longer

pretty sure this is a myth.

New generation of battery discharge when it's full??

Your colleague is an idiot. All laptops today bypass battery once it's fully charged.

No, your colleague is not an idiot, almost NO laptops bypass the mains when plugged in -- they continue to use the battery since that's the actual power supply for the laptop, not the mains (the mains is just a battery charger).

If you are solely using your laptop while plugged in, be sure your battery remains at least slightly charged while sitting around since a fully-discharged lithium battery is a dead battery. Operating a laptop without a battery obviously does not degrade any battery and is therefore good advice; the only downside is if you accidentally disconnect the power connection since you won't have the battery acting in its normal role as a UPS.

Guys, i have 2 laptops & i use both of them equally ( 6-8 hrs each a day) I started doing the same trick almost an year back; removing battery & plugged in all the time &  other one is being used just like the way every other person uses it;  with battery connected/pluggedin to a laptop  (continously getting charged). & guess what....."IT WORKS".

Well I agreed if you wish to make your laptop battery last longer you need to unplugged it after it fully charged and when your used power adapter.

But I like to leave the battery plugged in laptop because sometime I not regularly save my works, and it well be a disaster when their is no electric :)

Pretty useful advice and pretty useless advice at the same time. the good of having a laptop is that you can carry it wherever you want. if i have to remove the battery from it, it is like having a desktop computer. If i have to put the battery back every time i want to carry my laptop in the living room or in the bedroom...well it is going to be a pain in the butt, plus it will take all the fun away of having something portable

Strange, I always thought the battery had to stay in to use the notebook, that they would not run just on AC. Proves what I know.

Some laptops work on AC without the battery, and some dont. Remember, as noted above, without the battery, the slightest power hit or accidental jiggling of the power cord will shut your machine down - losing all your work. Its alot easier to accidentally loosen the power cord on a laptop than on a desktop.

This tip is probably more trouble than its worth.

i seriously doubt that. cause once a battery is fully charged they get disconnected from the main supply.
