Telling us it's a PC doesn't tell us whether it's a desktop or laptop computer.

If the subject computer is a HP Dv2422ca it's a laptop.

Having no video on a laptop's built in display is very common, after the laptop has been used a lot, or at any time if it's been dropped or had liquid spilled on it, or if your battery or charging system isn't working properly.

Since it last worked properly...

- have you dropped this laptop, or have you spilled liquid on it ?

- have you re-loaded Windows from scratch from a regular Windows CD ?

- have you just installed video drivers ?

How old is this laptop?

If it's over two years old, how long has it been since you changed it's main battery ?

Laptop no video (or video problems), and battery, AC adapter, power jack T shooting.

See response 1:

DO NOT plug in or unplug a monitor's video cable into / from a video port while the computer is running. Doing so can damage the monitor's circuits and/or the video adapter's circuits.

Some laptops will display on an external monitor without you having to do anything.

If you get no video on an external monitor, some laptops have a key combo that you must press to toggle the display to external video only / sometimes both / built in display video only - see the Owner's or User's manual for the model.
