My Compaq Evo N1000v not want to turn on

Do you get any lights when you have the charger connected?

Try removing the battery and see if it turns on.

If you have and know how to use a volt meter you can check your charger to make sure it is providing the proper power. The charger should have a label that says how many volts it provides. The inside of the connector that plugs into the computer is the positive (red probe on your volt meter), and the outside is the neutral or ground (black probe on your volt meter). Switch your volt meter to DC, and the reading should be close to what is written on the charger.
