In G70 notebooks there are only two screws securing the keyboard and they are located on the bottom (there is a small keyboard stamped close to each screw). Move the white clip about 2-3 millimeters towards the display panel and release the cable. If you accidentally break the connector, you’ll have to replace the motherboard. On the picture below the connector is shown in the unlocked state. Disconnect the switch board cable from the motherboard. Remove two screws securing the mounting brackets on the top. Now you can separate the LCD screen from the display cover and access the video cable.
I linked to service manuals at the end of this guide. It is not necessary to remove the memory and hard drive covers. Remove four (red) screws securing the keyboard cover. Disconnect the video cable connector from the motherboard. Remove these seals with a sharp object and remove screws found under the seals. If you are using this guide for replacing the keyboard, you have to remove only three (yellow) screws. Place the keyboard so you can access the cable connector underneath. In G50 and G60 the keyboard screws are located in the battery compartment. You have to unlock the connector and release the cable before removing the keyboard. The white clip must stay attached to the connector base. Move the cover towards the display to separate from the top cover. Turn the laptop upside down and disconnect two antenna cables from the wireless card. Furthermore, installing the wrong HP drivers can make these problems even worse.Recommendation: If you are inexperienced with updating HP device drivers manually, we highly recommend downloading the HP (Hewlett Packard) Graphics Card Driver Utility.
