Chapter 4. Troubleshooting Other problems Your computer does not respond. The computer does not start from a device you want. The connected external device does not work. • To turn off your computer, press and hold the Power button for four seconds or more. If the computer still does not respond, remove the AC power adapter and the battery pack. • Your computer might lock when it enters sleep mode during a communication operation. Disable the sleep timer when you are working on the network. • See the Boot menu of the BIOS setup utility. Make sure that the BIOS setup utility is set so that the computer starts from the device you want. • Also make sure that the device from which the computer starts is enabled. Make sure that the device is included in the Boot menu in the BIOS setup utility correctly. • While turned off, press the Novo button to select the device you want the computer to start from. • Do not connect or disconnect any external device cables other than USB while the computer power is on. Otherwise, you might damage your computer. • When using high power consumption external devices such as an external USB optical disk drive, use an external device power adapter. Otherwise, the device may not be recognized, or the system may shut down as a result. 28
