We’ve yet to see a Windows laptop with battery life longer than 5~7 hours, unless we add an extended battery to the system. But when hpand dell launched its new series of laptops last week, one big push wasfor longer battery life.
When you purchase your notebook, charge the battery to 100 percent,discharge it completely, and then fully charge it to 100 percent againto help the battery remember exactly how much electrical charge it canhold. From then on, you’ll never need to completely discharge the
laptop battery again, but always make sure when charging it that you let it reach 100 percent. DeHoop told us to “remember to plug in the
laptop AC adapter(or dock/port replicator) whenever you get a chance. Most notebookswill recharge quickly.” Salinas had another tip for your batteries:“Keep them cool. Exposure to high temperatures can be a battery’s worstenemy,” he said
Hope the list can give you some help when you purchase a laptop or battery:
