Dell XPS 12 9Q23 Troubleshooting
This troubleshooting page will help diagnose problems with the 12.5” Dell XPS 12 9Q23.
Computer Battery is Not Charging
The laptop does not hold a charge when it is unplugged or will not charge when the power cord is plugged in.
Faulty Power Adapter
First check to see if the problem is with the outlet and not the cord. To do so, unplug the charging cord from the current outlet and re-plug into a different outlet. If the problem persists move on to the second check.
The second check is to confirm that there are no exposed or frayed wires along the cord. First remove the power cord from the outlet and from the computer. Then, if there are frayed or exposed wires refer to on how to fix wires. If the cord displays no frayed or exposed wires, move on to the next check.
Next check both the adapter to the computer and the adapter to the battery box. For the battery box adapter, unplug the longer AC adapter cord and check to see if the metal prongs are bent or broken. If bent, gently use pliers to unbend. If broken, then the cord needs to be replaced. If neither, check the AC adapter to see if the prong inside the cylindrical circle is slightly bent. If so, completely unplug the AC adapter from the large battery box. Then take some small pliers and gently unbend the prong. Re-plug the AC adapter cord back into the battery box on one end and plug the AC adapter into the computer to test. If the AC adapter prong is unfixable or broken, it is time to buy a new cord.
Finally, confirm the power adapter is plugged in and the light is on. If the light remains off while the adapter is plugged in and all the above steps are cleared, consider a replacement. If the light remains on, check the Faulty Battery Section.
Confirm the power adapter is working. If the problem persists, then the battery is faulty and follow this guide on how to replace the battery.

Or, restart the laptop by holding down the power button for 30 seconds and tap the F2 key to enter the BIOS or System Setup. Charge the battery within BIOS. Verify if the battery charge percentage has increased. Restart the PC, and proceed to the next step.
The next step is to run the Dell ePSA built-in hardware diagnostics. To do so, first turn on the laptop, and tap the F12 key. Then choose Diagnostics from the menu. Answer any prompts accordingly. If the test fails, replace the battery. If the diagnostics test passes move on to the next step. For more information look at Dell’s more in depth .

Fan is Not Running
First check that there is not a debris blockage preventing the fan blades from spinning. Then check that the necessary wires are still connected to the fan.

Broken Keyboard Keys
The keyboard keys are stuck and you cannot type what you want with it or the keys themselves are cracked/broken/missing.

Next click the Search for Updates icon at the top of the screen (it looks like a computer monitor with a magnifying glass in front of it). Select Keyboards again and click the keyboard’s name. Once the name is highlighted click on the Update Device Driver icon at the top of the screen (it's in between the Search for Updates icon and the giant red ‘X’ icon). Click on the ‘search automatically for updated driver software’ option (it’ll be the first of the two options on the screen). Allow the newest drivers to install (they do this automatically). Close the window once it is finished installing, then Restart your computer.
