Please run the diagnostics to confirm hardware functionality. Here are the steps:
Restart the system and immediately start tapping the 'F12' key to enter the 'Boot Menu'.
Use the 'Down Arrow' key to highlight the 'Diagnostics' option. Press the 'Enter' key.
The diagnostics will begin. Please note the exact error message/code, if any appears on the screen.
Also, check if there is any issue with the LCD by running LCD BIST (Built in Self-test). To run the LCD BIST, press and hold the D key on the keyboard while pressing the power button, then release both at the same time. This will initiate A grey screen, then Red, then Blue, then Green then White, to allow you to inspect the entire LCD for color purity on each screen and to better identify defect such as cracks in the LCD or stuck pixels that may not be apparent in a normal viewing mode.
Please update the audio drivers and check if that fixes the issue. Here are the steps:
Enter the Service Tag of your system and select the operating system.
You will find the audio driver under 'Audio'.
Click on 'Download File'.
Select 'For Single File Download via Browser'.
Click on 'Download Now'.
Save the driver on your desktop.
Once the driver is saved on desktop, right click on it and select 'Run as administrator'.
Install the audio driver by following the on screen instructions.
Also, update the BIOS of the system. From the above mentioned link download the BIOS. Follow the same steps to update the BIOS.
Note: Make sure the ac adapter is connected and the battery is charged 10% or above to update the BIOS. Also, disconnect all the external peripherals before updating the BIOS. All the programs should be closed and documents saved.
Hope this helps. Please reply if you have any questions.
