Most newer Laptops will have a sturdy battery and there is no reason to remove it while you are also Plugged-In.
That said, as a maintenance procedure I recommend that you allow the battery to drain once a month as low as possible and then plug the power adaptor back in to recharge the battery fully.
You can play games while you do this.
Have fun Playing games.
So can i play games while charging?? Because someone told.me that it is dangerous because it might blow the battery inside. Or it becomes fat. Thank you in advance. Bythe way now i am doing like this charge the battery to full then plug out then play then after 10% battery i pluged in and wait to full before i play games again
Yes you can while the power adapter is plugged in and the battery is charging continue to play games.
Note however if it is not plugged in
stop playing games when the battery is down to 15% it looses its power rapidly after 15% so save anything in your games that you need to and perform normal tasks while you run the battery down as low as 5%. At 5% it normally stops working and powers down to a standby waiting for you to plug in the power adapter.
(NB: 5% is dependent on your battery (Power Options) settings)
