Sony Vaio PCG-61112L Troubleshooting

The screen is displaying black spots or pixel points.

If there are tiny black, blue, red, white, or green pixel points on the screen, be sure to clean off the entire screen surface with a soft dry cloth to rid the debris.

Keep in mind that the pixels appearance is normal for all LED displays while starting or in an all-white or black screen. Be sure that this is not happening during normal functioning. If the pixel points are still there, it is then best to replace the entire LED screen. You can find our guide here on how to replace the screen.

If you have recently dropped your laptop and cracked the screen, black pixels may appear where the crack has occurred. In this case, the best option would be to replace the screen altogether.

You are not able to hear sound through the laptop.

Make sure your device is not on mute. At the bottom right of the screen, click on the volume button. Click on the mute button to ensure the sound is on and not on mute. If the problem is not involved with the sound through the laptop, the problem may lie in the speakers themselves. Our replacement guide found here can help show you how to extract them.

The audio driver may be the cause of no sound. In this case, go to Control Panel on the laptop and find the Sound Control. You will need to uninstall the driver and restart the system. The sound should be functioning properly after the restart. If the problem is not resolved, you may need to upgrade your BIOS.

The screen remains black when trying to open webcam.

The webcam may not work due to updating the driver. This could lead to a change in the system which would make the camera not work. You will need to uninstall the update and restart the laptop.

Your laptop could have a faulty connection between the motherboard and camera. It is possible that the wire connecting the two is damaged, so the motherboard or the connecting wire may need to be replaced.

If you have recently cracked the external surface of your webcam, it is best to replace the camera. You can find our guide here to replace the webcam.

Laptop will not respond or open new applications.

The RAM or memory may be too small to work with applications open at the same time. You may need to be sure to close unused applications to be able to function without a problem.

Your laptop may be an older model that may need a new RAM to be able to hold memory. In this case, you may need to upgrade your RAM. Click here for a guide on how to replace the RAM.

Laptop will not fully load when turned on.

The CPU is handling a lot of calculations and tasks. It cannot update the screen in the rate as fast as the normal operation. If that is the case, just wait for few minutes until the laptop to finish the current task.

The laptop could be running slowly because there is insufficient RAM. To check how much memory is being used, open the task manager by pressing Crtl+Shift+Esc and navigate to the performance tab. Look under the Memory graph and see if a high percentage of memory is being used. If so, it may be useful to upgrade the amount of RAM in the laptop.

The hard drive may prevent the laptop from booting up. To resolve this issue, get a Windows DVD for the version that you have. Please note that the specific version does not matter, only that it is for Windows XP, Vista, 7, or 8. Boot to the DVD, and choose “Repair your computer,” then click next. On this screen, pick “Startup Repair” and let it run. If you are still having trouble booting up after the repairs, you may need to replace your current hard drive. You can find our guide here on how to replace the hard drive.

The entire keyboard is not responding to keystrokes, individual keys on the keyboard do not function properly (e.g., the F key does not type “F” when pressed, etc.), or the key has become detached from the keyboard and needs to be reattached.

Make sure Number Lock is disabled. If Number Lock is on, press the Function key (Fn)—the bottom left corner of the keyboard—and the Number Lock key (Num Lk)—the top right corner of the keyboard—at the same time.

Turn off the computer and restart it. If this does not work, continue to explore this troubleshooting section for other possible diagnostics.

If a key has fallen off it can easily be reattached to the keyboard. As long as the hinges have not broken, simply place the key in the spot it belongs and press down until you hear a click. The key should be reattached.

Shine a light under non-functioning key(s) to see if there are crumbs or other debris under the key(s). Spraying a can of compressed air should clean out any debris and fix the problem. If this does not work, taking the key off, cleaning the area with a dry cloth, and reattaching the key will work.

To be certain this is the problem, connect a USB keyboard to the laptop. If the USB keyboard works properly, then the ribbon cable is likely the problem. To check and repair the ribbon cable, follow the steps under the Motherboard Repair Guide and make sure all ribbon cable connections are securely made.

This occurs when either the trackpad or the trackpad buttons do not work/respond properly, or the cursor is unresponsive.

First check and make sure the trackpad is not locked by holding “Fn” and then pressing ‘F1”. After doing this, make sure to disconnect all devices such as mouse, printer, monitor, USB devices, etc. Next, reboot the computer by holding the power button until it turns off. Press the power button again to turn the laptop back on. Rebooting the computer allows it to locate the drivers for the trackpad or correct the issue. Once the computer has completely restarted check the trackpad. If the trackpad continues to malfunction, power down the computer. When you see the computer logo on the main screen, start tapping “F2” continuously until you get the utility settings. Then press the exit button, followed by the “get default values”. Click the yes button and then wait for the computer to start. Check to see if the trackpad works or if the problem continues.

Slightly lift up the button with a screwdriver or with a tool that is small enough to fit under the button. Use compressed air to clean around the button. If this does not solve the issue, the trackpad setting may be corrupted, or some functions may be disabled. Hold “Fn” and Press “F1” to turn trackpad on. If this does not work, open mouse settings in Windows control panel. Find the disable button. Click it to turn your trackpad on or off. The word “disable” refers to a non-operating trackpad, while the word “enable” refers to an operating trackpad.

Make sure no external pointing devices are connected to the computer. Disconnect any external pointing devices. After disconnecting/determining no external devices are connected, click start. Then, type “Vaio control center”, and press enter. Expand the section keyboard and mouse. Double-click “Built-in pointing device”. Make sure it is set to enable.

You will need to repair physical damage to the trackpad. Purchase of a new trackpad will be required and replacement must be done. To replace the trackpad, follow the steps under the Trackpad repair guide.

A weak wifi connection occurs when the internet runs inadequately, resulting in slow browser processing. Solutions to this problem include the following:

Unplug modem power supply for ten seconds. Then, restore power to the modem. This restarts the modem and often fixes internet issues after power outages.

In the case of the modem/router you may want to reboot it anyway, as it is not uncommon for one device out of many to not function correctly until it is rebooted. If there are several other devices connected to the same network, then WiFi connection can become slow. Turn the WiFi off on devices that are not in use. This will free up the network. Also, if the network is not secure, neighbors or passersby can access the network. Securing the network with a password can eliminate network crowding.

A router extends the wifi availability. If needed, a router can be purchased at most electronic stores. To guarantee a strong router signal, make sure one end of the cable attaches to the router, and the USB end attaches to the computer. Raise the antenna. Then, reconnect to wifi.

A wifi-card is what enables your computer to process the radio waves that make up a wifi signal. If this card is damaged or faulty in any way, your computer will be unable to connect to your wireless network. The best way to fix this issue is to replace the wifi card. First, purchase a new wifi card. Next, follow the simple steps found in the Wifi-Card replacement guide.

This occurs when the laptop’s system cannot take in cool air and expel hot air efficiently. When this occurs, the laptop may experience system inability issues such as slow processing, freezing (especially during demanding activity), abrupt shutdowns, and crashing. Loud fan noises are a common sign of overheating. Overheating may be caused and corrected by the following:

Move the computer to a hard surface, away from sunlight, and store it in a room with proper temperature control.

Ensure the voltage of the charger is correct and that the ventilation system of the computer is clear of dust and debris. If debris is present, clean the fan and vents on the bottom of your computer to remove the accumulation of dust. A can of compressed air or a dry cloth can accomplish this. To access the fan for cleaning, follow the steps under theFan repair guide.

When pressing the power button, the computer does not power up.

If this is the case, simply connect the power cable to the computer. Wait a few moments and press the power button. If the computer continues to not turn on, explore this troubleshooting section further for more resolutions to the problem.

If the computer remains operational while plugged in, but the battery does not charge, then you have successfully discovered a faulty battery. If the battery is determined to be faulty, purchase a new battery and replace the old battery. Fortunately, laptop batteries are easily replaced. First, remove the old battery and connect the new functioning battery where the old battery used to sit.

A short can be identified by wiggling the charger. If a connection is made when the charger has a kink in a certain spot, then there is likely a short. Using electrical tape to reshape the cord may work as a solution. In the event the wire is fixed by electrical tape, an alternative charger can be used to test the functionality of the original charger.

The purchase of a new power port cable is required to remedy this issue. However, the process of replacing a charging port requires a soldering iron. So, it may behoove you to let geek squad or some repair shop fix it to ensure the other hardware of the computer does not become damaged.

Determining whether or not the motherboard is dead requires ruling out other components, first. In order to do this, follow the steps on the Troubleshooting a Computer Motherboard iFixit page. If following these steps results in a dead motherboard diagnosis, follow the steps under the Motherboard repair guide to fix the problem.
