1. Disconnect the power cable and any printers, monitors or other peripherals you may have attached your M2000. Lay the laptop face down on a table, with the front of the laptop facing you.

2. Locate the hard drive on the right side of the laptop. Remove the two screws holding the hard drive cover in place and remove the cover. The hard drive will have a mylar tab on it to help remove it. Grab the tab and lift up on the left side of the hard drive until it disconnects from the motherboard. Pull the hard drive straight up to remove it from the hard drive bay.
   
3. Remove the single screw holding the optical drive in place. Stick the end of a bent paper clip into the disk tray release hole on the optical drive, located on the front of the disk tray. This will eject the disk tray. Grab the tray and slide the optical drive out of the laptop base.
   
4. Remove the memory modules. The memory compartment is located in the center of the M2000. Remove the two screws holding the cover in place and remove the cover. Use your fingers to spread the latches on the sides of the memory modules and slide the modules out of the sockets.
   
5. Remove the mini PCI card by first removing the last cover on the bottom of the M2000. Remove the screws on the cover and remove the cover to reveal the mini PCI card. Disconnect the white and black wireless antenna cables from the card. Spread the latches on the sides of the card and slide it out of the socket. Disconnect the antenna cables from the clip attaching them to the laptop base.
   
6. Remove the keyboard cover and LED board by first removing the two screws in the battery bay. These hold the keyboard cover in place. Flip your laptop over and open it up. Slide a flat-head screwdriver into the notch behind the "F1" key to unlock the keyboard cover. Do the same thing at the "F5," F11," and "Insert" keys. Pull the cover up to remove it. The LED board is under the cover. Disconnect the data cable from the motherboard and remove the two screws holding the board in place. Remove the board.
   
7. Remove the keyboard by first removing the four screws holding the keyboard in place. Lift the back end of the keyboard up and tip it over so it is resting face down on the palm rest of your M2000. Disconnect the data cable from the motherboard and remove the keyboard.

Remove the 18 screws holding the base enclosure in place. Lift the rear end of the base enclosure up until it comes free from the laptop. Once it's free, slide it back to remove it.

Disconnect the cables from the motherboard and remove any screws holding the components in place. Lift the components straight up to remove them.

To remove the CPU, turn the locking screw counter-clockwise until it clicks. Grab the CPU by the edges and lift it straight up. Put the CPU in an antistatic bag for safekeeping.

HI,
Your compaq is and password protected and need to disable if you want to do so. It could BIOS password or OS password.
You CD rom should give response while you insert the CD. The indicator light should blinking and motor should turning. Further more you may broken lens, wires problem.
You need to check to find where does the problem lies and take necessary action to get them fixed.
Regards,
Jay
