Sony Vaio PCG-Z505R Troubleshooting
- 1). Check the power adapter on the Sony Vaio PCG-Z505R if there appears to be a lack of power to the machine. This adapter needs to be securely plugged into the back of the laptop. Additionally, it must not have come loose from the wall socket or surge protector outlet it is plugged into.
- 2). Consider battery replacement if power problems continue after ensuring the adapter is in place. Batteries last for roughly 1,000 charges before they deteriorate. Power the machine off and disconnect the power adapter. Insert a new test battery in the Vaio by flipping the unit over and activating the sliding battery-release mechanism, which is located at the top of the underside of the unit. This mechanism will pop out the old battery and allow you to insert a new one for testing.
- 3). Check the keyboard ribbon cable if the keyboard has stopped functioning properly. This is often the cause behind keyboard malfunction. Remove the screws on the bottom of the unit that are marked with a small keyboard icon. Use a Phillips-head screwdriver.
- 4). Flip the Sony Vaio PCG-Z505R back over and jostle the now loose keyboard free from the housing. You will see the keyboard ribbon cable running from the bottom of the Vaio keyboard down to the base of the laptop, where it is supposed to connect to a socket. Reconnect this cable if necessary. Lift one edge of this socket gently up and slide the cable back in, then push firmly down on the keyboard socket to lock it back in place.
- 5). Check the monitor brightness settings on the Sony Vaio PCG-Z505R if the display appears dark or blank. The brightness settings may simply have been turned all the way down, resulting in a display that only appears to be malfunctioning. Brightness adjustment keys can be found at the top of the Vaio’s keyboard.
- 6). Ensure the monitor’s inverter cable has not become disconnected if the screen’s backlight appears to have failed and remains dark after attempting brightness adjustments. Notice the plastic seals along the surface of the perimeter of the display. This plastic perimeter is also known as the "bezel," and these seals on the bezel conceal screws. Pry off the seals with your fingers and remove the screws with your screwdriver.
- 7). Pry under one edge of the bezel gently to pop it up. Work around the perimeter of the loose bezel with your fingertips to disengage it and remove it entirely.
- 8). Locate the inverter cable. This is the black cable that runs along the bottom center of the exposed display and which connects to the inverter board beneath it via a connector socket just off to the side. If the inverter cable is loose, lift up on one edge of the socket, slide the cable back in, then press down to lock the socket into position. This will restore the monitor’s backlight.
