Toshiba Satellite E45W-C4200X Troubleshooting

The laptop will not power on and shows no sign of turning on.

Make sure that the laptop is charged. Use the factory provided power cord and make sure it is securely inserted into the laptop’s charging port. There should be a light on the laptop and the cord to indicate charging.

If the light on the adapter is switched on, make sure the adapter is connected to the laptop. If the laptop is powered only when the adapter is plugged in, regardless of the charging time, the battery is defective. Replace the battery using the battery replacement guide.

If the battery is charging intermittently or extremely slow, the charging port in the laptop may be loose. Replace the charging port using the DC Power jack replacement guide.

The screen is not responding to any keys, trackpad, or touch inputs.

Power off the laptop by holding down the power button until the screen goes black and the laptop is shut off.

Make sure that the trackpad is not accidentally disabled. To do this, hold down the “Fn” key in the lower corner of the keyboard and then press “F5.” If the trackpad was disabled by accident, then this will re-enable it.

To re-enable the touch screen for the laptop. Hold down the “Fn” and then press “F4”.

If all other solutions have been attempted to fix the display of the screen then the whole screen will need to be replaced. Use the screen replacement guide

There is no sound coming out of the speakers

Using the function keys, make sure the volume is not muted and is turned to a reasonable level. If that does not work, go into the control center in the settings and manually turn up the volume.

Ensure that there is nothing plugged into the 3.5mm jack on the left side of the computer. This would cause the audio to channel through that line instead of the speakers.

If none of the above steps yielded results, the speakers will need to be replaced. Replace the speakers inside the computer.

There is sound coming out of the speakers but it doesn’t sound normal

Try using a pressurized air canister to blow out any dust or dirt that may be altering the sound coming out of the speakers.

Use an external speaker or set of headphones to ensure that the problem is isolated to the speakers. If the sound is the same, the problem might be the source (video, music file, etc.), also check the mixer settings in the control center and restore to factory defaults. If the audio in the external speakers is normal, the computer speakers will need to be replaced.

The speakers work just fine but nothing you plug into the audio jack plays any sound

Make sure that you check several other devices to make sure that the problem is not the device itself.

Using a flashlight, inspect the inside of the 3.5mm jack on the left side of the computer. If there is a foreign substance inside the jack, turn off the computer and use tweezers to remove the obstruction.

If the 3.5mm jack on the side of the computer is cracked or loose, the port will need to be replaced.

While the computer is on it gets very hot.

Try using a pressurized air canister to blow out any dust or dirt that may be stopping the fan from cooling.

If the cooling fan is not clogged, it will need to be replaced. Use the cooling fan replacement guide.

One or more keys are stuck, missing, or broken.

Make sure that nothing is in between or under the keys. Keys may need to be removed and cleaned to resolve this issue.

Make sure that the keyboard is not locked, and ensure there is no external keyboard plugged in. If the keyboard still not responding, it will need to be replaced.

Replacement keys will need to be installed.
