Now a days we started using the laptop instead of PC. The major advantage of laptop is power saving. This is true, we can surely save the power as it is having rechargeable batteries. But do we use that properly???
Many of us (including me ;-) before ) done the same mistake, that when ever i will start work then i will switch on the charger also. But this is not required, In case you are a frequent traveling person you can have two batteries. The impact of always keeping the laptop in charger will reduce the life of batteries. Make sure the battery is mostly dried then only you can charge it again. Otherwise the life of the battery will reduced.
