Base Board Serial Number changed twice after BIOS IC repair and HP account shows a different laptop

[elizmj]

Hello everyone,

I need some advice regarding my HP Pavilion Laptop 15.

My original laptop details are:

• Product ID: 6PT92EA#UUG

• Serial Number: <Please do not include the product serial number or any private information>

The laptop underwent a BIOS IC repair. During the repair process, the Base Board Serial Number changed twice:

• Original factory Base Board Serial Number:

  >Do not include the product serial number or any private information<.

• After the first BIOS IC repair: PHZYA018JC11ET

• After DMI information was reprogrammed:

  >Do not include the product serial number or any private information<.

   (current)

Currently, the BIOS/DMI reports:

• Product ID: 6PT92EA#UUG

• System Serial Number: #

• Base Board Serial Number: RGUND7FS1CICUS

However, my HP account still detects a completely different device:

• Serial Number: #

• Product: HP Pavilion 15-cs2010tx

My questions are:

1. Is it normal for the Base Board Serial Number to change from the original PHZYB028JCG0UA to PHZYA018JC11ET, and then again to RGUND7FS1CICUS, when only a BIOS IC was repaired and no motherboard was replaced?

2. Should a BIOS IC repair or DMI programming alter the Base Board Serial Number at all?

3. Why does my HP account still recognize a different laptop even though the BIOS now shows my correct Product ID and System Serial Number?

4. Does this indicate incorrect DMI programming, or does HP need to update the device information on its servers?

I would appreciate guidance from HP experts or anyone familiar with HP DMI programming.

Thank you.
