Dell Inspiron 14-5447 BIOS/HDD Password(s) Assistance needed.

When first turning on the laptop I get:

Harddisk Security
SATA Port 0 ST1000LM024 HN-M101MLock

After 3 incorrect p/w tries I get:

System Disable

Service Tag

The Seagate hard drive serial # is: S314JA0F703871

When I replace the original HDD and turn it on, I get a different box saying:

Enter Current Password

After 3x it shows:

System Disable

Same service tag of course but the system disable code is different with the new drive.

Asking for help is usually a last resort for me. My apologies if I didn’t post this correctly, it’s my first time here.

Please help a disabled veteran out. Thanks so much in advance.
