The laptop is unable to save any more files, or is slow to pull up files
Navigate to the file explorer and check your current hard drive storage in the “my computer tab.” If the storage is full, you can either gain space by deleting files, transfer files to an external storage source, or upgrade the internal solid state hard drive using this replacement guide.
Speakers on the device are either not playing sound or playing corrupted sound
Ensure that the volume on the device is not muted or that the media is indeed playing the correct sound. A good way to test whether the audio issue is from the media file or from the computer is by alternating the sound output from the speakers to headphones. To do this, plug a pair of headphones into the headphone jack, play the audio file, and listen to the output from the headphones. If sound comes out of the headphones, the problem is with the device's speakers. You can replace them using this replacement guide.
The speakers on the device may be broken and replacement is required. To replace the speakers follow this replacement guide.
The back camera does not function properly
