Sony Vaio PGC-31311L Troubleshooting

An 11.6", Wi-Fi capable laptop with 4GB of RAM. Identified by model number PCG-31311L. Manufactured by Sony in 2011.

Internet Connection Issues

The computer will not connect to the internet using Wi-Fi.

Wireless Router Issues

Check to see if other devices are connected to the same network. If not, then the router may be the issue. Check your wireless router or cable modem for connection problems.

Wi-Fi Connection Issues

If other devices are connected to the network, check to make sure the wireless switch is ON. Also, check to make sure the wireless option in VAIO Smart Network software is ON. Lastly, try reinstalling the wireless drivers on the device. If the connection issue persists, the Wi-Fi card may be to blame.

Audio Issues

The audio is very quiet or non-existent

Little or No Audio

Check to make sure the volume is not turned down or muted. If the volume is unmuted and there is still no audio, open the "Playback settings" and make sure the speakers are set as the default device.

Distorted Audio

If the volume sounds distorted or there is static, plug in headphones and check the audio again. If the headphones sound normal, it may be an indication of a faulty speaker(s). Consider replacing the speaker(s).

The Device Will Not Power On

Faulty Battery

Plug the power adaptor into the device and verify that the charging light on the adaptor is on. If so, and the device is still not powering on, check our [battery removal guide] and consider replacing it.

Loose Charging Port

If the power adaptor is plugged in and lit up, but the charge light on the device isn't turning on, then the charging port on the computer could be loose or damaged. check out our [DC Jack Replacement Guide].
