HP Notebook PCs - Purchasing a replacement AC power adapter

Purchase a replacement AC power adapter that is designed for your notebook if the original one fails. You might also want to purchase an additional power supply for travel or use in an alternate location.

Test the power adapter

Use one or more methods to check the operation of the AC power adapter.

Check the power icons

Use the system tray icons to confirm the AC adapter does not work.

Connect the output cord from the AC adapter to the notebook, and then plug in the power cord to a working electrical outlet.
Check the power icon in the system tray.
- If the icon resembles a power cord, and if moving the cursor over the icon displays the On AC Power message, the AC adapter works.
- If the icon resembles a battery when the AC adapter is connected, the adapter does not work.

Check the AC power adapter (removable battery only)

Check if the AC power adapter powers the notebook when the battery is removed.

Turn off the notebook.
Remove the battery from the notebook.
Connect the power adapter, and then turn on the notebook. The notebook should start and operate normally.

If the notebook does not start and operate normally, the power adapter does not work.

Order an AC power adapter

AC power adapters are designed for specific notebook models. Find your product number, and then use it to order an AC power adapter from the HP Parts Store.

Note:

Some countries or regions might not be supported when ordering parts from HP.com. See your local HP retailer or contact HP directly to purchase additional power adapters, batteries, or other parts.

Find the product number for your notebook. Look on the notebook for a product information tag, or press fn and esc to open the HP System Information window. In Windows 10, you might need to download HP System Information from the Microsoft Store.
Go to the HP Parts Store.
In the Find your part field enter your product number, and then press the Enter key.

Note:
Remove the suffix from the product number. For example, DZ357U#ABA is entered as DZ357U.
If prompted, select your model number.
In the Category search box, select Batteries and Adapters from the drop-down menu. One or more compatible power adapters display in a parts list.

Note:
Unless explicitly written in the description, the power adapter does not come with a power cord (the cable that connects to the power adapter and the wall outlet).
To choose a power adapter, type the quantity, and then select the check box in the last column.
Click Proceed to checkout to finish ordering the part, or click Add to Cart to add the part and continue shopping for other parts.
