The HP V3000 notebook has a battery, and the screen will be black when the power cord is unplugged. Why?

Hello! Thank you for choosing HP products.

According to your description, I suggest you refer to the following information:

I suggest you try plugging and unplugging the battery of the machine again to see if the machine still has this problem. If there is no problem after plugging and unplugging, it is probably caused by poor battery contact. It is suggested that you can solve this problem by erasing the golden finger of the machine. If the problem of the machine still exists after you plug and unplug the battery again, it is suggested that you can directly contact the local HP Gold Service Center for testing and handling. It is likely that there is something wrong with the battery. For the contact information of the Gold Service Center, you can choose your province and city and the product type you use through the following websites:
