Laptop Batteries and Chargers
Maximise your laptops up time
Your laptop powers itself from the mains power supply and charges a battery. These batteries last from 3-5 years, sometimes longer. But the older they get, the quicker the power runs out. A new battery can help to regain the length of uptime.
Open applications on a laptop will take power from the machine, but the energy-saving is minimal if you close them.
