Troubleshooting and problem resolution: 1. Check to see if any of the following devices are located less than one meter from the computer: refrigerators, electric fans, electric dryers, UPS systems, regulators, fluorescent lamps or other computers that may be generating magnetic interference. Move any interfering devices away from the computer. If the problem persists, contact Lenovo Service. 40 User Guide 5. 2 Troubleshooting Audio Problems Problem: No sound from the integrated speakers. Troubleshooting and problem resolution: · AdjusttheWindowsvolumecontrol--double-clickthespeakericoninthe lower-right corner of your screen. Ensure that the volume is turned up and the sound is not muted. Adjust the volume, bass, or treble controls to eliminate distortion. · Disconnectanyheadphonesfromtheheadphoneconnector--soundfrom the speakers is automatically disabled when headphones are connected to the computer's side-panel headphone connector. Troubleshooting and problem resolution: · Checktheheadphonecableconnection--ensurethattheheadphonecableis securely inserted into the headphone connector. Check the specifications that came with your computer to confirm that this optical drive is capable of reading this type of CD or DVD. If the CD/DVD cannot be read, replace it with a known good CD/DVD such as one that was shipped with the computer. If the known good CD cannot be read, visually check the operating side of the CD/DVD for defects. Problem: The capacity of the hard disk, as indicated by the system, is less than the nominal capacity. Troubleshooting and problem resolution: For computers equipped with the OneKey Recovery feature, the system recovery feature needs to occupy some hard disk space. This may account for the apparent hard disk capacity deficit. 42 User Guide Further Technical Explanation: The nominal capacity of the hard disk is expressed in the decimal system as 1000 bytes. But the actual hard disk capacity is expressed in the binary system as 1024 bytes (For example, the nominal capacity 1G is 1000M, while the actual capacity 1G is 1024M). The capacity of the hard disk shown in Windows can be calculated according to the calculations in the following example: The nominal capacity of the hard disk is 40G, while its actual capacity should be: 40 x 1000 x 1000 x 1000/(1024 x 1024 x 1024) = 37G. If the Service partition of 3G - 3 x 1000 x 1000 x 1000/(1024 x 1024 x 1024) = 2. 79G is subtracted, the capacity of the hard disk shown in the system can be obtained. The capacity of the hard disk as calculated using this method may be slightly different from the actual capacity due to the rounding of totals. 5. 5 Special considerations for troubleshooting Windows 1. Record the serial number of the computer as it may be useful later when troubleshooting system problems.
