Sony Vaio VPCW21FX Troubleshooting

Your laptop will not power on and respond to action

Your laptop may not be powering due to improper connectivity to either the wall or the power adapter port itself. Make sure that the power adapter is plugged in correctly and light responds accordingly. If the adapter is plugged in with no light, the adapter itself could be faulty and a replacement may need to be purchased.

The battery may not be properly secured to the laptop itself. Remove the battery using the latch and reattach it making sure that you hear a click. Attempt to power on computer and if it doesn’t respond, the battery may be dead. Charge for approximately 10 minutes and attempt to turn computer on. If the computer does not turn on, your battery could be faulty and a replacement may need to be purchased.

The device will not fully turn on and crashes during start up.

Other symptoms of a hard drive often include disappearing files and strange humming sounds. If the operating system fails to boot due to a damaged hard drive, it may need to be replaced.

If drivers on the device become corrupted or damaged, the device will be unable to start. Start your device in “Safe Mode” in order to default your drivers to factory settings and reboot your computer.

Even though the device has been plugged in for 30+ minutes, the battery percentage will not increase.

There are many instances of people not recognizing that their power cord isn’t working, therefore the device will not charge. According to Sony, this device takes 35 minutes to fully charge. If no results are seen by then, your power cord could be broken and need to be replaced.

The power jack is located where the charger is plugged in to the device. Being reckless with plugging/unplugging the power cord may cause damage to the port.

Device speed is not to full potential.

Many people do not have antivirus software installed on their device. In these cases, clicking the wrong link or web page could download a virus. Download one of many free antivirus software and run a check of your computer. If a virus is found, you may need to restore the device to factory settings.

If your device freezes or reduces speed the longer it is powered on, you may have a faulty RAM. You may need to add more RAM to your device, or simply replace the corrupted RAM.

Doing too many things at once on your device can lead to a high expenditure of CPU or memory, which will overheat your device and cause it to run slowly. Close unnecessary programs, uninstall applications that you do not use, and don’t run programs that are too power intensive.

Your Sony Vaio screen is not showing a display while powered on

If the screen is showing no display or is black even when powered on, the screen could be disabled. To enable screen again, press “Fn” and “F2”. If screen was disabled, all functions involving the screen should return. If not, there could be a wiring issue and the screen may need to be replaced.

Attempt to restart the computer first. When the computer restarts, the display should be corrected. If there are still visible scratches, pixilation, or lines causing distortion on the screen you may need to replace the display itself.

You have trouble hearing audio on or from your computer

Make sure that the speakers are unmuted and the volume is enabled. If that does not work, right click on the speaker icon on the lower right hand corner of your screen and click “Playback devices”. Check that you are under the “Playback” tab and that your computer speakers are selected.

Be sure to test your audio through your computer speakers, then check with external headphones. If the sound is distorted only with headphones, the audio jack or headphones may be malfunctioning. Make sure that both the audio jack and the headphones are properly inserted into your computer.

Your touchpad or keyboard will not respond or is missing keys

If a key is missing or pops off from your keyboard be sure to keep it in your possession. You can reattach it by pressing it firmly down back onto the keyboard or replace.

Dust and debris may be collected under the keyboard causing the keys to stick. If they cannot be pressed, remove the keys and effectively clean the area. Return the keys back to their intended position afterwards.

The touchpad could be disabled if it does not respond. Press the “Fn” and “F1” buttons on the keyboard first to test whether it is enabled. Try pressing the “Fn” and “F1” buttons again and if there is no change you may need to replace the touchpad.

The fan on your laptop is malfunctioning in some way or another

Check to make sure that noise is coming from the actual fan and not on any other part of the laptop. The sound from the fan vent may indicate you need a BIOS update for your device. If after the update sound persists, you may need to replace or repair the fan itself.

If your computer is continuously overheating during use, the fan may be causing a problem. If the fan is not properly working for your laptop, the fan may be defective and need repair.
