    Default Use laptop while charging???

    Hi!
    I just wanted to ask that can I use my laptop when it is charging i.e. connected to AC mains??? Some people say that doing so reduces the battery life. Whenever u have to use it on main line, remove the battery and then use. But its too cumbersome 4 me coz most of the times, I use it at home where ac line is available. Wt should I do? Any good suggestions?
    Thanx

    Many people is worrying about battery.

    A battery has something like 2 or 3 years of life and whatever you are doing to take care of your battery, she will anyway loose performances.

    The best thing to do is to use your laptop in the most comfortable way for you and when you see that your battery has lost 80% of the normal performance, buy one if you still using the same laptop.

    You can remove the battery while the laptop is operating, that is no problem. The reason why it's not recommended to keep the battery inside the laptop when running on AC is that it generates a lot of heat (from the battery charging, thus the laptop runs even hotter than usual).

    Heat is bad for both computer and battery, but it's very likely that the battery will feel it first. When you unplug the laptop and find out the battery only lasts 30 minutes, you'll know it. And batteries aren't exactly cheap. I have seen plenty of batteries fail within 6 months because of this.

    This is a prehistoric reason. It remember me my first cell phone. Actually when a battery is fully charged, the charger doesn't charge it anymore.

    Similar to mobile charging, laptops should also be intelligent enough to stop the charging when its completed.

    Why does the CPU gets overheated while battery charging ?? The battery is not heated at all.. !!

    I am using Lenevo Y410.

    I was talking about a laptop plugged but with a fully charged battery.

    While a battery is charging, this is different. Everything is running hot and it's normal.

    Then why do batteries left inside the notebook fail within 6 months? After the battery reaches 100% the charger still provides a "trickle charge" to keep the battery at that level. And Li-Ion cells don't like being kept fully charged for too long either.

    Are you telling me that if i let my charged battery in my laptop while the laptop is plugged, i'm sure to get battery failure?

    Because i never removed the battery from any laptop and i had some of them for years without any problem.

    I just sold an Acer few months ago. I bought this laptop from a friend (second hand in mint condition) just to be my cheap (350$ and less than 60w consumption...) "home download station" and i never turned off this laptop for more than 5 minutes (just reboot). After many years like this, i tested the battery before i sold it and the laptop ran 30 minutes before shutting down... Not that bad for a pretty old machine.

    If 30 minutes is great battery life to you, then i agree, you'll still have great battery life after 3 years on the AC line. You just gave the perfect example. After 3 years at 100% charge the battery ran for an astonishing 30 minutes. That means nothing bad can happen to your batteries if you keep them charging all the time, if a never-used battery lasts for 30 minutes then it's in perfect condition.

    Besides, HP batteries are a bit different from those from Acer. Hint: they wear out a lot faster.

    Just a little experiment for you: Try putting a battery in the freezer for 3 years, then tell me how long it lasts when you take it out vs one that has been in the laptop and charging at all times.

    You can use your notebook while charging and you can leave the battery in while on AC. The key is to cycle the battery (discharge the battery from full until your computer shuts off - windows shuts down) at least once a month. That ensures good battery life.

    Using this method, you will see no difference in overall battery longevity between taking the battery out while on AC or leaving it in while on AC.
