Unresponsive Keys ¶ 

Keyboard not registering keystrokes

Debris Under Keys and/or Dirty Keyboard ¶ 

In a clean environment, use compressed air to blow out around the keys not working. If they are still not working, remove the key using a pry tool and clean the keys with rubbing alcohol. Be sure to not over saturate the keyboard with rubbing alcohol to prevent damage from liquid residue.

Keyboard Printed Circuit Board (pcb) is Non-Functional ¶ 

If cleaning the device did not resolve the issue, it is likely that you will need to replace the keyboard, see {location of guide} for a guide on replacing it.

Blank Screen/Monitor ¶ 

The screen has no picture when the laptop is on and active.

Malfunctioning Graphics Hardware ¶ 

Try connecting an external display to the laptop to see if the computer is outputting an image. If the external display does not work, you may need to replace the video card or other related graphics hardware, see {location of the guide}. If the external display does work, try changing the output settings of the device back to the laptop screen. If there is still no picture, your screen may have failed, thus see {location of guide} for instructions on replacing it.

Failed Display ¶ 

You can check connections to ensure everything is secure to the screen. If no faulty connections, you may need to replace the screen, see {location of guide}.

Computer Will Not Power On ¶ 

"Computer won't turn on or does not respond to power button."

Dead Battery ¶ 

Plug in the device charger, an then try turning on. If it turns on but dies when you unplug the charger, you have a failed battery. The battery will need to be replaced, see {location of guide}.

Failed Power Supply ¶ 

If device won't turn on when plugged in, you could have a faulty charging cable or power supply. These will need replacement, see {location of guide}.

Headphones Don't Work ¶ 

"Headphones produce no sound when plugged into the headphone jack."

Headphone Jack is Dirty ¶ 

Ensure the operation of headphones on a known working device and check your sound output settings to see if the computer registers the headphones being plugged in. If your headphone jack is dirty, the connection to the headphones will not work. Clean the headphone jack with compressed air or a toothpick, be careful not to damage the port, and try headphones.

Faulty Headphone Jack ¶ 

If headphones work on another device and the port is clean, your headphone jack has failed. The jack will need to be replaced, see {location of guide}.

Speakers are not working ¶ 

"No sound is produced or sound is distorted."

Sound is outputed to wrong destination ¶ 

Check your computer sound settings to ensure the device is attempting to play through speakers.

Blown Speakers ¶ 

If you are hearing sound but it comes out distorted, the speaker may be blown. The speaker will need to be replaced.

Loose Connection ¶ 

If you hear nothing and the sound output destination is correct, there may be a loose connection on the speakers or the speaker has failed, see {location of guide} on replacing it.
