HP Compaq V3000 adapter is the number of V
Hp also seen 18.5v. 18.5v can also be used
You view the notebook product warranty card product name information, if the letter u at the end of the integrated graphics;
If the letter x ends, it is configured for the discrete graphics.
You can also view the output (input / output) in the power adapter label configured with the notebook to confirm the specific information.
Hope that the above reply can help you.
