how to remove the keyboard

Keyboards become worn out over time. Individual keys can become damaged, become less sensitive to key strokes, or disengage from the keyboard. Keyboards can also become corroded from spills. Many keyboards on HP laptops can be replaced. Hewlett-Packard has made hundreds of different laptop models. Each model may require slightly different steps for replacing the keyboard. To locate a replacement keyboard, you can contact HP directly or another online or offline source that sells computer parts.
1.Power off the laptop. Flip the laptop over to access the device's underside.
2.Remove the battery cover and take out the battery.
3.Remove a screw to the left of the memory bay. This screw will be one of two resting in the middle of the underside of the device. You want to remove the right screw, the left screw is attached to the CD/DVD-ROM drive, not the keyboard. (This screw may be red in color.)
4.Flip the laptop back over and raise the laptop screen so you have access to the keyboard area. Insert the tip of a Flathead screwdriver along the bezel and detach it. Carefully pull the bezel up and set it aside. The bezel is connected to the device with a ribbon cable. Do not remove this ribbon cable. (The bezel is the above the laptop and is the cover that houses the power button.) Once the bezel is up, notice the three screws that are beneath it.
5.Unscrew the three screws holding down the keyboard.
6.Lift the keyboard forward toward the mouse area. Be careful, it is still connected to the motherboard by a keyboard cable.
7.Release the cable from the keyboard. Push both ZIF connectors on the side of the cable upwards, toward the laptop screen. Pull the cable from the connector and the keyboard is now released.
8.Insert the keyboard cable of the new keyboard into the ZIF connector. A pair of tweezers may be required to put the cable in place. Lay the keyboard flat down and rescrew in the screws. Replace the bezel cover. Flip the keyboard over and replace the screw on the underside near the memory bay. Insert the battery and battery cover.

battery problem

It's quite possible that the battery was not replaced correctly. Many of them are quite sensitive to proper replacement. Remove it again and carefully inspect the metal contact areas on the battery and inside the laptop to determine if any got moved out of place or damaged. Check your Manual for correct insertion of the battery and carefully put it back in as indicated in the manual. It Must completely click into place and be aligned properly so all of the contacts meet. The edges of the battery should be smooth along the laptop case and fit as one.
