Check Your Original Power Supply

Confirm your current adapter shows 12V output and either 2.5A or 3A rating on its label. Ensure the DC plug measures 5.5mm outer diameter and 2.1mm inner diameter. Match the part number on your old unit to the Y27FE-120-2500U or Y27FE-120-2500J references.

Questions about this item

Does the adapter need a specific laptop model such as the HKC B2000 or a part number like Y27FE-120-2500U to work?

The adapter is listed as compatible with the HKC B2000 and part numbers Y27FE-120-2500U and Y27FE-120-2500J, so one of those devices or part numbers is required for proper fit.

Can I keep using my original 12 V 3 A power supply alongside this 12 V 2.5 A adapter?

Both units deliver 12 V; the original supply provides 3 A while this adapter provides 2.5 A, so the original can remain in use if its connector and polarity match.

How can I verify the adapter is working correctly after connecting it?

The adapter includes an LED indicator that lights when power is being delivered, confirming normal operation.
