Sound is distorted or not present
Sounds problems could be anything ranging from crackling and popping sounds coming from the audio port, to your sound controls no longer working, or the symptoms could be exhibited by working sound controls and no audio output.
Computer Could Need to be Rebooted
The first way the sound problems can be fixed is by simply rebooting the computer. In order to do this navigate to the start menu in the bottom left hand corner of the screen on the computer, and select the restart option.
Computer May Need the Drivers Updated
If rebooting does not work try going to the start menu on the computer, then type “control panel” into the search bar. Now, go to “system and maintenance,” then go to “system” and then to “device manager”. Once in the “device manager” check to determine if the device is installed properly, this can be verified by looking for any yellow exclamation points or red X’s. After checking for this make sure that the driver is updated.
Rolling Back the Sound Driver
First navigate to the “device manager” menu and select the “driver tab”, once in the driver tab select the rollback driver option.
May Need to Reinstall the Audio Driver
First navigate to the “device manager”, once in the “device manager” menu click on the audio driver tab. When in the audio driver section click on the uninstall driver button (red X on the top bar of the screen), not reboot the computer. Now that the driver is deleted just initiate a windows update in order to reinstall the driver.
Distorted microphone audio
Microphone problems can be noticed by failure to record sound when the microphone is in use. In addition, the microphone may be distorting audio that it is recording instead of failing to record any sound.

Loose connection
The microphone may not be plugged in properly, ensure that the microphone is properly plugged in by taking it out of its connecting port and then plugging it back in
Microphone driver may be improperly installed
If this doesn’t work your problem may be with your microphone driver.

If the driver is properly installed you should try to update your driver if it is not up to date. To do this go to the “device manager” and click on “microphone” inside of “audio inputs and outputs”. After this click on the microphone option and click update driver in the top bar.
Microphone driver may need to be rolled back
Sometimes updated drivers actually cause an issue with your device drivers.If your driver has been recently updated before your device malfunctioned you should go to your microphone inside of the “device manager” and instead of clicking “update driver” click “rollback driver”.
Microphone driver may need to be reinstalled
If none of these solutions have worked so far you can try removing and reinstalling your microphone driver. Navigate to the “device manager” and click on the “microphone driver” inside of “audio inputs and outputs”. After navigating to the microphone click on “uninstall driver”. Following this reboot the device and initiate a windows update which will reinstall your microphone driver.
May have conflicting software or hardware
The next solution available is to remove any recently installed hardware or software which might conflict with the microphone driver.
May need to reinstall windows
Finally, if all of these solutions have not helped your microphone drivers function you should try reinstalling your operating system to restore function to the microphone.
Mouse moving without your interaction
Touchpad problems may exhibit themselves by loss of touchpad function. Additionally, the cursor may not be smoothly responding to your inputs.
Loss of touchpad Settings
The first way you can possibly fix your malfunctioning touchpad is verifying that your computer didn’t drop your touchpad activation settings. To do this, go to the “start menu,” type “control panel” in the search box, and then press “Enter.” Then go to your “hardware and sound settings.” Often times this will have an icon of a printer and speaker next to it. Select the “devices and printers” option. This will take you to a page that contains all of you peripherals. Then click “mouse” and navigate to “mouse properties”. Once this is open verify that there is a check next to “enable touchpad.” If there is not, then select that field and then select apply and close the window. Immediately after this, the touchpad should begin functioning again. If there is not field for this option, or this option does not work, follow the next guide.
No Tab for touchpad in device and drive menu
In “mouse properties” click on the hardware tab and check for a field labelled “HID-compliant mouse.” If you are using a connected mouse there may be two of these fields. Click the one that does not have USB in location property. Click on properties for “HID-compliant mouse”, and check the device properties. Click on change settings under the driver tab and click update driver button and then you will likely have to restart your computer, and your touchpad should be working properly.
Loss of connection in FFC
To check for this you need to open the laptop and find the FFC that is connected to the touchpad and verify that it is plugged in. If the cable is plugged and the above steps failed to work then you will likely have to replace your touchpad.
Keyboard failing to register inputs
Keyboard issues will be noticeable when you try to type something with a specific key and the input is slow or not recognized.
May need to reboot your laptop
First try to reboot your laptop by navigating to the start menu and clicking “restart” if this does not work move on to the next steps.
Keyboard may have a bad connection
Loss of keyboard function is often due to the keyboard being plugged in incorrectly or coming loose. To check if this is the issue you should plug in an external keyboard via USB and see if it works. If the external keyboard works your laptop keyboard has a loose wire and needs to be plugged back in.
Keyboard driver may need to be updated
Besides being unplugged a keyboard can also malfunction due to a driver error, if your keyboard is wired in correctly you should try to update the drivers by going to “control panel” in your start menu, “System and maintenance” in the control panel, then click “system” and then “device manager”. Once inside the device manager navigate to your keyboard driver and click update. If this does not work try reinstalling your keyboard driver.
If all of these options did not work you may need to replace your laptop keyboard.
Device failing to power on or charge
A power on issue could be occurring when your device fails to launch when you press the power button, or if the battery is failing to charge.
A fault in the charging adapter

If the charger is in working condition then attempt replace the battery using this battery replacement guide.
Loss of BIOS settings
A random loss of BIOS settings will look something like an error such as an invalid system disk, boot failure, hard disk error, NT boot loader missing, or missing operating system.
External Device Causing Loss of Settings
If a USB flash drive or some other USB device is connected to the computer try and unplug the device before starting the computer.
Reset Computer to Factory State
