Sound isn’t working or is distorted when your laptop is not plugged in.
If your audio only becomes distorted once you unplug your computer and it is running solely on battery power, you may want to check your battery saving preferences on your laptop. On your laptop go to your notification area in the RHS corner. Then select: winXP -> Control Panel -> Battery Saving -> High Performance. By selecting “High Performance” in your Battery Saving Preferences, you will most likely resolve this issue.
If changing your battery saving preferences did not work, check to see if the audio issues only occur when you are using headphones. If the audio is only distorted while listening with headphones, the headphones might be the part that is faulty. Furthermore, ensure that your headphones are fully plugged into the computer so that you are checking if the issue is a loose audio jack.
In order to ensure your battery is holding a charge, plug it in and check to make sure the charging light is on. If it seems that the battery is holding a charge, it could be an issue with the battery itself. Refer to our Battery Replacement guide for further instructions on replacing a faulty battery.
If your computer will not turn on it may be to the battery is not getting a charge.
If you have tried turning on your computer and it will not respond, First try to see if your computer is plugged in check to see if any of the plugs are loose in the back of the desktop or the outlet in the wall.

If your power supply is damaged it must be removed and replaced with a new power supply. First make sure your laptop is unplugged from the wall outlet. Next unplug your power supply block it is normally at the back of the laptop near the fold. Clean the power socket as best as you can before inserting the new power supply block.
Sound is either not playing at all, or the audio is distorted.
Begin by looking at the settings on your computer. At the bottom right hand corner, there will be an icon for speakers. Click on it and ensure that it is not on mute and set at a reasonable volume to hear (>30). If so, then go to the audio clip that you are trying to play and ensure that that also has not been set on mute.
Similar to when Audio is distorted on battery power, check to see if the audio issues only occur when you are using headphones. If the audio is only distorted or not working while listening with headphones, the headphones might be the part that is faulty. Ensure that your headphones are fully plugged into the computer so that you are checking if the issue is a loose audio jack.
If all of the above have not worked, it may be an issue with the actual speakers. They may have gotten damaged through incidental drops, water damage, or simple wear and tear. Please follow this guide to replace the speakers.
