Know the Complete Information About Your Laptop’s Battery

If there is anything frustrating about a notebook or a laptop, it’s the battery. When you buy a laptop, the battery is brand new and thus it gives power backup for 3-5 hours. But after a few months, the backup time reduces to a great extent.

This is because of the habit that we use laptop keeping the AC power ON all the time. As a rule of the thumb, you should unplug the AC power and use the laptop running on battery power. When the power is drained out, you should shut down or hibernate the computer and put the notebook back on AC power.  Keep it for an hour and wait for the laptop to get fully charged. Then start using the laptop as usual.

This is the advice computer vendors give us but we hardly follow this routine because of two reasons. First, our lives are too busy and there is no time to wait. You can not afford to spend an hour without the computer, just because it’s charging. Hence, the laptop is always put on AC power which considerable damages the battery life.
