Replaces Lower-Watt 7.4mm Barrel Adapters

Use this 150W unit wherever a 130W / 90W / 65W 7.4mm barrel was supplied; your device will negotiate its required power.

130W class (7.4mm barrel families): common PA-4E / 130W kits and model codes such as DA130PE1-00, LA130PM121, HA130PM121
90W class: PA-10 / PA-3E 90W families (7.4mm)
65W class: PA-12 / LA65 65W families (7.4mm)

What’s Included

• 150W AC adapter with 7.4mm x 5.0mm barrel
• AC wall cord (when included by kit)

Fit Notes

• Use with notebooks that originally shipped with a 7.4mm barrel adapter rated up to 150W.
• Systems that specify 180W / 210W / 240W require the corresponding higher-watt adapter.
• 7.4mm barrel only — not for 4.5mm blue-tip or USB-C systems.

Quick Label Check

• Output line: should read 19.5V 7.7A and typically shows 150W; minor punctuation/spacing differences are normal.
• Connector ID: barrel measures ≈7.4mm outer / 5.0mm inner with a center pin. If yours is the smaller ≈4.5mm blue-tip or a USB-C port, this is not the right adapter.
• Power inlet style: brick uses a C5 three-prong AC inlet (cloverleaf). If your old brick uses a flat 2-prong C7 cord, double-check the model.
