Can the adapter (the same nominal voltage but the output current is different) be used in the same laptop?
The adapter voltage is the same, but the output current is different, can it be used in the same laptop? The basic principle is that the adapter of large nominal current can replace small nominal current one. Someone will probably think that the adapter of large nominal current will damage the laptop due to large current. In fact, the current is decided by load in the case of same voltage. When the laptop is under high-load operation, it requires larger current. When the laptop is in standby status, it requires lower current. The adapter of larger nominal current has enough current margin. On the contrary, if someone uses a 56w adapter to replace 72W one, it will also work, because usually the adpater is designed to have a little margin. The load power is less than the adapter power, so it is viable to use a 56w adapter to replace a 72W one, but the remaining power margin is become lesser. Once you connect your laptop with other external devices, such as two USB hard drives, and make the cpu run in full speed, or even connect one more docking station and charge your battery at the meantime, then you should take care and touch your adapter to see if it can be used to boil eggs. Therefore it is not recommended to use small current adapter to replace large current one.
