Released June 2010
Dell Inspiron Duo Won't Turn On
Pressing the power button does not turn the device on.
Power adapter is connected
Before checking anything else, make sure that the device has power. Ensure that the power cable is properly connected to device, and plugged in to an outlet. If necessary, disconnect, then reconnect the power cable from the device. Also ensure that the adapter is working, and wires are not frayed or worn.
If the device won't turn on while on battery power, there could be an issue with the battery. Visually check the battery by removing the cover and ensuring there is no corrosion. If there is corrosion, the battery will need to be replaced, and the connectors cleaned. Click here to access step-by-step instructions for replacing the battery.
If the power light comes on, but the screen is black, then it is likely that there is an issue with the display. If faint images are appearing on the screen, or you can see the display only by holding a flashlight to the screen, then the screen will need to be replaced.
Keyboard keys are not working
Pressing the keyboard keys causes them to repeat, or nothing happens when keys are pressed.
Check the keys for any sticky residue or dirt underneath, and remove keys to clean if necessary with soap and water.
If the keyboard is unresponsive, the keyboard might need to be replaced.
Device is hot to the touch, or shutting off intermittently.
If dust is visible on the outside fan ports of the device, dust buildup inside of the device is likely. Use compressed air to blow the dust out of the device.
Fans Not Functioning
If the device is warm to the touch and fans cannot be heard while device is on, the cooling fans may need to be replaced.
Not Enough or Old Thermal Paste
If there is no dust, and the fans are functioning, remove the CPU and check to see that the thermal paste is not dry, and that there is enough (there should be a pea-sized amount). If it is dry, or there doesn't appear to be a pea sized amount, completely clean remove thermal paste and add new, pea sized amount of thermal paste.
For further guidance on recognizing, removing, and applying new thermal paste, please see this guide.
