Be careful with Dell supplies. Modern ones may be different this is from ~15 years ago
They still do this.
Interestingly, Dell and HP use compatible "Big Barrel" and "Small barrel" power connectors. The voltage and polarity are the same. A Dell adapter will work just fine on an HP laptop, because the HP does not use the third pin to identify the adapter. However a Dell laptop will complain about an HP adapter because it cannot read any identifier on the third pin.
