120W Replacement Power for Compatible HP Business and Workstation Systems
When a compatible HP laptop or workstation stops charging, powers off under load, or the original AC adapter has been lost or damaged, identifying the correct power-supply part number is more reliable than choosing an adapter by wattage alone. The HP PPP016L-E, HP Part No. 619484-001, and LiteON PA-1121-42HP references identify a 120W-class AC/DC power adapter platform designed for compatible HP systems.
This adapter provides 19V DC at approximately 6.32A, delivering about 120W of rated output power. The model, HP part number, electrical rating, and connector should all be compared with the original adapter before replacement.

OEM Replacement Compatibility
This adapter is identified by the following power-supply references:
- HP PPP016L-E
- HP Part No. 619484-001
- LiteON PA-1121-42HP
These identifiers should be checked against the label of the existing power adapter. Matching the complete part number is recommended because HP has used multiple 19V adapters with different wattage ratings and connector configurations across its laptop and workstation product lines.
Compatible Devices
The PPP016L-E / 619484-001 power platform is intended for compatible HP business-class laptops and workstation systems requiring a 19V, approximately 120W external power adapter.
Because HP used different adapters across closely related product families, verify the exact laptop or workstation model together with the adapter part number before ordering. The device model alone should not be treated as sufficient proof of compatibility.
Replacement & Fault Diagnosis
A failed AC adapter can cause symptoms that resemble a laptop hardware problem, including a battery that will not charge, intermittent power loss, failure to start, or shutdowns when the system is under heavier load. If the original adapter is damaged or no longer produces the required output, replacing the external power supply can restore normal operation without replacing the computer itself.
For a PPP016L-E replacement, compare the original adapter's HP Part No. 619484-001 or LiteON PA-1121-42HP reference, 19V output, approximately 6.32A current rating, and connector configuration. Do not select an adapter solely because the plug physically fits.
Power Requirement & Compatibility
The 19V output and approximately 6.32A current capacity provide up to 120W of rated power. A replacement adapter should have the correct voltage and connector configuration, while its current capacity should meet the requirements of the HP system.
Using an adapter with a different voltage can cause improper operation or damage. A lower-wattage adapter may also be unsuitable for a system that requires more power, particularly during processor-intensive or workstation workloads.
Frequently Asked Questions
What is HP PPP016L-E?
PPP016L-E is an HP power-adapter model associated with HP Part No. 619484-001 and LiteON P/N PA-1121-42HP. It is a 120W-class AC/DC adapter with a 19V DC output.
What are the output specifications of PPP016L-E?
The adapter is rated at 19V DC and approximately 6.32A, corresponding to approximately 120W of output power.
What is HP Part No. 619484-001?
619484-001 is an HP power-supply part number associated with the PPP016L-E adapter platform. LiteON identifies the related adapter as PA-1121-42HP.
Does PPP016L-E use an HP 7.4mm x 5.0mm connector?
The adapter platform is associated with the larger HP barrel-style connector with a center pin. Verify the connector on the original adapter before ordering, especially when replacing an adapter from a different HP product generation.
Can a different 19V HP adapter replace PPP016L-E?
Not automatically. The replacement must also have a suitable power rating, connector configuration, polarity, and compatibility with the specific HP computer. Matching 19V alone is not sufficient.
HP PPP016L-E, HP Part No. 619484-001, and LiteON PA-1121-42HP identify a 120W-class AC/DC power adapter providing 19V DC at approximately 6.32A for compatible HP laptop and workstation systems. The adapter uses an HP-style DC barrel connector with a center pin and is intended as a replacement when a matching external power supply is lost, damaged, or failing. Buyers should verify the exact HP adapter part number, device model, output rating, and connector before ordering.
