Troubleshoot Hardware

• 1). Click "Start." Right-click "My Computer" and choose "Properties" from the contextual menu.
  
  
• 2). Select the "Hardware" tab, then click "Device Manager." Locate the device in the list of categories.
  
  
• 3). Double-click the device to open its properties. Click the "General" tab. Look up on the Microsoft Support page any errors displayed in the "Device status" window (see the Resources). Enable the device in the "Driver" tab if "Device status" lists the device as disabled.
  
  
• 4). Click "Driver." Click "Update Driver." Windows will search its database for any software updates to your device.
  
  
• 5). Click "Uninstall" to remove the driver for your system, if the above steps do not resolve the issue. Restart Windows XP. The operating system should automatically reinstall the driver for your software. If the component fails to work after troubleshooting the driver, the device may need to be replaced.
  
  

Troubleshoot Power

• 1). Check the connection leading from the power adapter to the power jack on the side of your Toshiba Tecra. Plug the power adapter into a wall outlet.
  
  
• 2). Confirm the power cable is connected securely to the adapter itself.
  
  
• 3). Turn the Tecra 2100 over and confirm the battery is properly inserted into its bay. Confirm the battery tab is in the locked position.
  
  
• 4). Turn the laptop back over and open the lid. Press the power button. If the laptop fails to power on, hold the button down for 15 seconds. Wait, then press the power button again. Listen for any beep codes which might indicate a problem with the hardware.
