Product: HP EliteBook 840 G3 Notebook PC
Operating System: Microsoft Windows 10 (64-bit)
Hello. I recently bought a replacement battery at an authorized HP service center. However, the HP PC Hardware Diagnostics for Windows and the HP Support Assistant apps could not identify the serial/TC number.
- The HP PC Hardware Diagnostics for Windows result was Primary_BatteryCTNumber: abcdefghijklmnop
- The HP Support Assistant result was CT Number: N/A
What does this mean for the authenticity of the battery I got at the authorized HP service center? Is this a common theme with genuine/original battery replacement?
Thank you in advance.
