Asus X751L Troubleshooting
This troubleshooting page will help you identify and resolve common issues with the ASUS X751L.
Laptop will not turn on
When plugged in to the power adapter, your Asus X751L will not turn on
Faulty Power Adapter
If the power light is off, the adapter and/or the power cord are not functioning correctly. Check if any connections with the adapter and the power cord are loose. Check if there are any damages to the adapter or the power cord. Try charging with a new adapter and a power cord.
If the power light is on, the adapter and the power cord are functioning correctly and the issue is likely with the major components. Remove the battery and all external devices (USB, memory card, HDMI cables etc.) to directly provide power supply to charge. If the laptop boots up properly, the battery may no longer be functioning correctly and needs to be replaced.
You have trouble listening to sounds on your laptop.
Loose Headphone Jack
Test audio through the computer speakers, then test it using an external audio device. If the audio is only distorted while listening via external audio device, the the audio jack or the external audio device themselves may be faulty. Audio may be distorted by loose connection with the audio jack.
If the audio sound is distorted when listening through the laptop’s speakers, the audio driver may be corrupt or outdated. Check out the ASUS driver page and select the appropriate operating system (OS). Select AUDIO and click on the latest RealTek Audio Driver that is appropriate to your computer. Restart computer and check the laptop's speakers again.
