HP 15-g029wm Troubleshooting

The laptop is connected to power, but not charging.

Check the serial number of the Cord and Adapter. Both should match up to these:

AC Cord: 490371-001

Adapter: 741727-001

If the above serial numbers do not match, it is recommended that a replacement charger be ordered from an Authorized Parts Retailer.

The AC adapter is a part of the charger which plugs into the laptop. Take this part and carefully visually inspect it to determine if the brick at the end has any damage.

The portion of the brick that connects to the DC adapter may have had its prongs bent or broken off. If that section appears fine, the part that plugs into the laptop may be bent.

A tell-tale obvious sign of a faulty charger is melted or misshapen plastic along any part of the charging cord and brick. The brick should be rectangular with smooth edges.

If damage is found please contact HP for a replacement part or click here.

The DC adapter is a part of the charger which plugs into the wall. Take this piece and see if the electrical plug prongs are bent or missing.

On the other end, there will also be an electrical connector that connects to one side of the brick AC adapter.

If the plastic on there is melted or damaged. CAUTION: DO NOT PLUG IN. Contact HP for a replacement part or click here.

If you notice the cord of the laptop has exposed wiring or cuts into the plastic stop use.

This is most common in two areas the part that plugs into the laptop itself and then the wall plug area.

If there is notable physical damage contact HP for a replacement part or find a replacement part here directly from HP.

Check the laptop bottom and side air exhaust vents for debris. Carefully clear it out by using compressed air, then a microfiber cloth. This can be done by following this video tutorial.

Then, verify you are using a manufacturer (HP) certified/original charger.
