An external monitor works Good. This way you know the problem is either the Video Cable, or inside the Display Assembly.
With the Compaq Presario C700 series of Notebook PC's, the Video Cable connects to the motherboard; in an area under the Keyboard, and Switch Cover. (Above the F4 key)
It then leads under the left Hinge, and up into the Display Assembly. From there a small cable branches off, and connects to one side of the Screen Inverter. The main part of the Video Cable, goes on to connect to the back of the LCD screen.
The large connector on the Right side, connects to the back of the LCD screen. The smaller connector shown at Bottom connects to the motherboard. The small cable leading up to the Top/Left, connects to the screen Inverter.
Just from repeated normal opening, and closing of the laptop; the Video Cable may become pinched, and pulled on. Sheath of Video Cable also hardens over time, and this also adds to the equation.
However, this laptop has been dropped. There's a real good chance of a problem with the Video Cable.
Pulling on it can lead to the connections coming loose. Motherboard side, screen Inverter cable, and LCD screen side.
Procedure is to go through the various connections, and PHYSICALLY check them. Try to plug them in tighter.
Motherboard connection: 1) Remove ALL power. Remove the AC adapter (Charger), and Battery.
2) Disconnect the Keyboard, HOWEVER do not disconnect the Keyboard Cable from the motherboard.
Once Keyboard is removed from Palm Rest Cover, take the LCD screen side, and roll the Keyboard over. Bottom side up, lay on Palm Rest Cover.
3) Now remove the Switch Cover. The Switch Cover is the wide strip of plastic, above the Keyboard, and below the Display Assembly.
The Switch Cover is just that........a Cover. No wires attached.
Physically check motherboard connection. Reinstall power. Turn laptop on. No change? Remove ALL power again.
LCD screen side connection and screen Inverter connection: 4) The plastic frame in front of the LCD screen, is the Display Bezel. Remove it.
Right behind the Display Bezel, and mounted on the bottom/middle of the Screen Frame; is the screen Inverter. Just physically check the screen Inverter connection, but go on to the LCD screen side connection.
The LCD screen is an assembly of layers. These layers are held in the factory set position, by a metal Screen Frame. Resembles a picture frame.
Attached on either side of the Screen Frame, are Brackets. The brackets are attached to the Hinges, and the whole assembly is just referred to as a Hinge.
There are screws that hold the Hinge brackets to the Screen Frame. There are also screws that hold the Screen Frame together. Be SURE as to which screws you remove. You do not want to remove the Screen Frame screws.
Remove the screw that hold the Hinges to the Screen Frame. Tilt the Top of the LCD screen forward towards you, and physically check the LCD screen side connection; of the Video Cable.
Lay the LCD screen back, put a screw in on each side, to temporarily hold the LCD screen in place. Reinstall all power. Turn the laptop on. Still no joy?
Remove the Video Cable. The Video Cable needs to have a continuity test performed, with a multimeter set to OHM's. (1K) Every wire in the Video Cable is checked. No reading on a wire indicates a stretched/broken wire.
An assistant should also be used, to gently wiggle the Video Cable while checking. An intermittent reading on the multimeter indicates a stretched/broken wire.
Or take the Video Cable down to the nearest small computer repair shop, and have the resident tech check it for continuity. Should only be a coupla' bucks.
The Video Cable MUST be ruled out, before going on........
5) Video Cable checks out OK, or a replacement is used; and still no display on laptop's internal monitor, the screen Inverter is next in the diagnosis.
To test a screen Inverter requires a sensitive multimeter. Read fairly expensive,
Your laptop's power button sits directly on top of a device called a power button board. This is a small circuit board where all power and control buttons interface with your laptop's motherboard. The repetitive use of the power and control buttons can damage the power button board. Repairing your power button means removing and replacing the power button board, which requires partial disassembly of your laptop.
1.Power down your laptop. Unplug the AC power adapter and all external devices from the computer. Close the laptop's LCD panel and place the laptop face down. Rotate the laptop so the front opening edge is facing you. Remove the battery pack from its compartment on the laptop's bottom side.
2.Flip the laptop over, and pull open the display panel as far as possible. Use a thin, flat-head screwdriver to pry the keyboard cover from the laptop. The keyboard cover is the plastic piece situated above the keyboard assembly that houses the power button board.
3.Lift the keyboard cover out of the laptop slightly, and disconnect the cables extending from the power button board to the motherboard. Remove the keyboard cover from the laptop.
4.Place the keyboard cover face down on a flat surface. Remove the Phillips-head screws fastening the power button board to the cover, and remove it. If your speakers are situated inside the keyboard cover, disconnect the speaker cables from the power button board before removing it.
5.Place the new power button board inside the keyboard cover. Align the screw holes on the button board with the holes on the keyboard cover. Replace the Phillips-head screws fastening the button board to the keyboard cover. Reconnect the speaker cables to the button board, if necessary.
6.Reconnect the power button board's main cable to the motherboard. Place the keyboard cover back inside the slot above the keyboard assembly. Press down on the cover until it snaps into place. Replace the battery pack and reconnect all cables.
To access the mouse cable remove the battery - remove the screws securing the keyboard - carefully lift the keyboard out and check the security of the cable BUT in your instance look at the small on / off button in front of the mouse pad and ensure it is turned on ( blue light ) for on yellow off -- if it is blue go to Started - all programs - recovery manager - activate recovery manager - select advanced options - select reinstall a selected driver - select the touch pad driver - reinstall - reboot if that fails go to http://h10025.www1.hp.com/ewfrf/wc/softwareCategory?os=2093&lc=en&cc=us&dlc=en&sw_lang=&product=3872064#N1238 & download & install the latest touch pad driver. If still no go your up for a new top cover assy 498410-001Chassis
top cover assembly - With touchpad (Presario)
Also it maybe the on / off cct board assy that failed 502907-001Touchpad

y this procedure. It very serious problem. For someones... To remove that password there are few steeps:
0. remove AC power 1. remove system battery (primary and multibay if present) 2. remove harddrive from harddrive bay 3. remove Multibay Devices from multibay 4. remove small round battery pill 3.3V, located under a cover on left side of touchpad. Remove cover gently (is no need to remove keyboard, but cover is removable with some power...) Delicate unplug small conector with cables leading to battery, 5. wait 5 minutes 6. connect AC power 7. Turn on computer unit (BIOS gets a few errors = date, time, mismatch etc. no need to panic, if everything is ok then get into computer setup pressing F10, change existing setup values as needed, if ok power down computer. 8. unplug AC power 9. Plug small battery into motherboard 10. install Hdd and multibay devices 11. Install system batteries 12. Power Up computer, there could be no password anymore
It is a known fault with the speakers - obtain a replacement set but be aware though the panel is easy to lift the plugging in of the cables into the m/board requires some dexterity.part number from hp,
Switch cover - Plastic panel above keyboard that houses the LEDs, power switch, and Internet buttons plus speakers
You do not need to dismantle to base, you have some star screws under the battary and one either side that loosens the small panel near the screen (where the power button is). The screen cover has screws under the plastic covers then just unclips, be gentle. after that it is self evident
