My hp pavillion dv7 keyboard lock lights keep flashing; at one point the computer didn't want to boot up; I finally got that up today after six months. But the cap lock and the number lock lights still flash and the battery won't charge and it is less than a year old (the battery).

Instructions

1

Shut the Pavilion dv7 down and close the screen. After unplugging all cables from the computer, turn it over and remove the battery.
2

Unscrew the six Phillips-head screws holding the large T-shaped panel to the bottom of the Pavilion dv7. Remove the panel and set it aside.
3

Remove the keyboard locking screw--marked by a keyboard-shaped icon--from the top part of the compartment exposed when you removed the T-shaped panel. Reserve the screw.
4

Remove the black Phillips-head screw from next to the wireless adapter inside the T-shaped compartment. This screw holds the Pavilion dv7 optical drive in place.
5

Pull the Pavilion dv7 optical drive gently out of its bay, and then remove the two Phillips-head screws from inside the empty drive bay. Reserve the screws.
6

Remove the Phillips-head screw next to the circular intake fan vent in the corner of the Pavilion dv7.
7

Remove the five Phillips-head screws from inside the empty battery compartment. You should now have removed 16 screws in all. Turn the Pavilion dv7 over and open the screen.
8

Insert a spudger or other flat plastic tool into the seam between the speaker grille and computer casing on the right side of the Pavilion dv7. Gently pry up to begin removing the speaker grille from the computer. As you do this, move the spudger to a new location to pry different areas until the grille is completely disconnected. Mind the ribbon cable connecting the center of the speaker grille to the logic board, and do not lift the grille any higher from the computer than the cable allows.
9

Push both sides of the speaker grille cable lock forward until the cable slides easily out of the logic board connector. Set the speaker grille aside.
10

Remove the four Phillips-head retaining screws above the top row of the Pavilion dv7 keyboard. Lift the keyboard up and forward, and place it face-down on the palm rest.
11

Unlock the Pavilion dv7 keyboard cable connector using the same method as for the speaker grille connector. Slide the cable out of the connector, remove the keyboard and set it aside.
12

Place the new Pavilion dv7 keyboard upside-down on the palm rest. Slide the keyboard into the connector, close the lock and rotate the keyboard down into the computer. Replace the four Phillips-head screws.
13

Slide the speaker grille cable into the connector and close the cable lock. Push the speaker grille into its original position above the Pavilion dv7 keyboard. Press gently on all parts of the speaker grille until it is flush with the computer casing.
14

Close the screen and turn the computer over. Replace the five screws inside the battery compartment, the screw next to the intake fan vent, the two screws inside the empty optical drive bay and the screw inside the T-shaped compartment.
15

Replace the t-shaped panel on the bottom of the Pavilion dv7 and its six screws.
16

Slide the optical drive back into its bay and replace the securing screw.

Hi, at startup try pressing f8, this should give you a menu, select 'start windows with last good configuration', this should restore windows to the state before it started rebooting randomly. Failing that...try starting in 'safemode with command prompt' and then do a 'system restore'- press f8 again at start up and then follow the instructions below. this should restore your system to a previous state when the computer wasn't doing random things.

1. Restart your computer, and then press and hold F8 during the initial startup to start your computer in safe mode with a Command prompt.
2. Use the arrow keys to select the Safe mode with a Command prompt option.
3. If you are prompted to select an operating system, use the arrow keys to select the appropriate operating system for your computer, and then press ENTER.
4. Log on as an administrator or with an account that has administrator credentials.
5. At the command prompt, type %systemroot%\system32\restore\rstrui.exe, and then press ENTER.
6. Follow the instructions that appear on the screen to restore your computer to a functional state.

I hope that this helps you to sort out the problem. Toni

1. Remove 6 screws from the bottom of the case (as shown). These screws hold the accessory cover.

2. Remove one screw securing the CD/DVD drive. Slide the CD/DVD drive to the left to disconnect it from the motherboard. Remove the CD/DVD drive.

3. Remove all marked screws from the bottom of the notebook.
The yellow circled screws secure the keyboard cover, and the green one secures the HP Pavilion DV7 keyboard.

4. Turn the computer display-side up and open it as far as possible. Insert a guitar pick or small flat screwdriver between the keyboard cover and case and slowly move along the side.

5. Lift the keyboard cover. Be careful, it's still connected to the motherboard. Release the zero insertion force (ZIF) connector and disconnect the cable from the LED board. Remove the keyboard cover.

6. Remove the four screws that secure the HP Pavilion DV7 keyboard.

7. Lift the rear edge of the HP Pavilion DV7 keyboard until it rests at an angle. Slide the keyboard back to disengage the tabs on the front edge of the keyboard from the top cover and rest it on the display.

8. Release the ZIF connector to which the keyboard cable is attached and disconnect the keyboard cable. Remove the HP Pavilion DV7 keyboard.

reinstal your pc, i think this caused by virus

Please check by booting the Computer to Safe Mode, if the Computer boots as expected then Update the Video Driver.

ok it sounds like your battery was damaged when it discharged. try removing the battery and plug in to wall socket. boot computer ,.. if it boots up completely then you will need to replace your battery

you need to talk to a tech spport personally for a step by step process of reomoving and replacing the keyboard. they dont post manuals on their site.

What do you mean it powered on to the blue light?
Does anything show up on the screen?
Does the system usually beep when it starts? If so, does it beep now?

Same issue - solved by disconencting everything (main battery, CMOS battery, RAM, hard disk and wireless card). Held in power button for 20 seconds (HP say this removes any electostatic charge on the main board). Reconnected everything and machine booted to Windows. Ran HP's onboard diagnostics and everything checked out OK.
