Laptop works on battery but not the charger (HP Pavilion DV7)

Microsoft Windows 10 (64-bit)
Dear community,

I have recently disassembled my laptop in order to clean the dust. As soon as I assembled it back the computer started perfectly. However, it was not charging. It isn't one of the "Plugged but not charging" issues as the computer is not detecting that the charger is plugged in.

I disassembled the laptop again to check if any connections were not plugged in correctly. Everything looked fine. It's not my first time disassembling laptops.

The light on the charger port does not light up when the charger is plugged in. However, it is flashing white as the battery is critically low. When I press power button it flashes amber color. I have tried to remove the battery and start the laptop but it won't start.

Does anyone have any idea of what the issue could be?

Thank you

You might want to take a look at this document: Battery Does not Power Notebook or Hold a Charge.


It suggests troubleshooting steps to determine if the problem is the battery, the power supply, or the system board.

You might find the answer to your battery/power issue as you work through the steps in that HP support article.




Hope this helps, for any further queries reply to the post and feel free to join us again !!
