Why is my laptop not charging?
Often your laptop will be plugged in but not be charging. Common causes of why it will not be charging are because of a faulty charger. Laptop chargers can sometimes supply power to charge the battery to enable power for the laptop to function. When the charger cable is damaged and requires replacement, it may mean the laptop is powered up but the battery is not charging. In this case, consider a universal laptop charger as a quick and cheap alternative.
