Proper packaging is good to keep all laptop parts safe and undamaged. You can protect all the components either internal or external by packaging them in the required way. For this, wrap or enclose the untangled and organized cables in a small box or bag.

Wrap the laptop and its peripherals in cushioning material like bubble wrap and then put it in a bag or box. Try wrapping the accessories or related devices separately for maximum protection.

It’s better to provide your valid ID proof representing you as a citizen of India. However, while selling online, enter IMEI, the model number of your laptop so that you can keep a record/track of your device to ensure no one is misusing it in any way. Also, if it happens then their internet can be used to track illegal activities being carried on by them using that laptop.
