Lenovo 65W Type-C Laptop Charger for ThinkPad X1

The load power must always be less than the adapter’s rated power.

Using a lower current adapter to replace a higher current one is not recommended, especially when connecting many high-power devices, as it may be unsafe.

2. Is it normal to see sparks when plugging into the power adapter?

Sparks may occur if the adapter is connected to the laptop before plugging into the power outlet.

To avoid sparks, follow these steps:

(1) Turn off the power outlet switch.

(2) Connect the laptop power adapter to the power outlet, then turn on the outlet switch.

(3) Connect the adapter’s DC plug to the laptop.

3. Is it normal for the laptop adapter to become warm?

Yes, it is normal for all laptop chargers, including phone chargers, to generate some heat.

This is due to part of the electrical energy converting into heat.

However, if the adapter becomes hot enough to burn your hand, it indicates a poor-quality charger.
