HP Pavilion dv7-3074ca laptop ac adapter-replacement HP Pavilion dv7-3074ca power supply

This is a laptop ac adapter ( laptop power supply ) replacement for HP Pavilion dv7-3074ca; It is rigorously tested, meets or exceeds original HP Pavilion dv7-3074ca laptop ac adapter ( laptop power supply ) specifications, brand new with 1 year warranty.

It is very important to compare our adapter's output voltage with your original adapter's output voltage, to compare our adapter's output voltage with your laptop computer's input voltage! They must be same voltage. Adapter with wrong output voltage will burn the computer.

Output power ( W )=output voltage ( V ) X output current ( A ); for example, 90W=19V X 4.74A

The HP Pavilion dv7-3074ca adapter's output current can not be less than the computer's rated input current. Otherwise, the adapter will be overloaded and become very hot and burned. However, adapter with high output current can work well with the computer as long as the output voltage is correct.

The computer needs low current when you are editing files or writing emails. The computer needs high current when you are running discs or seeing a film. Normally, the HP Pavilion dv7-3074ca adapter does not provide the computer with its maximum output current. Computers only draw as many current ( amperes ) as they need.
