Lenovo ThinkCentre 41N5622 - Manual (Page 27)

Appendix B. Problem solving
Computer problems can be caused by hardware, software, or user error. Using the
information in this section, you might be able to solve problems yourself or gather
helpful information that you can pass on to a service technician. You might also
need to refer to your computer, operating-system, or sound-adapter
documentation.
Review the following list for any problem description that might fit your situation.
Transporting data with DVD-RAM Media
DVD-RAM Media can be read on any ThinkCentre DVD-ROM drive which has
RAM-read compatibility, but certain requirements must be satisfied. Your system
either must have a 2.0 compliant UDF reader or you must finalize the media
before it can be read.
If you do not have a 2.0 compliant UDF reader:
After data is written to the DVD-RAM media, it must be finalized before it can be
read in an ThinkCentre DVD-ROM with RAM-read drive. Finalizing the media
does not prevent the user to write more data. The DVD-RAM media may be
finalized more than once. It is impossible for the ThinkCentre DVD-ROM with
RAM-read drive to read the media which has not been finalized.
If you have a 2.0 compliant reader:
Unfinalized DVD-RAM media can be read.
Obtaining a 2.0 compliant UDF reader:
Free third party UDF reader software, such as VOB InstantRead, can be
downloaded from http://www.vob.de/us/Downloads.htm
Third party software is not supported by Lenovo. Use at your own risk with no
warranties expressly written or implied.
v Your computer or DVD-ROM drive does not operate correctly, or the busy
indicator light does not come on.
Take the following actions:
1. Check that the disc is loaded with the label side up.
2. Check that all devices are properly connected to the computer and to the
electrical outlet.
3. Turn off the computer, unplug the cables for your computer and all attached
devices, and remove the computer cover.
4. Check that all power and Serial ATA cables are securely attached. Disconnect
the Serial ATA cable and check for bent or misaligned pins. If you do not
find any problems, reconnect the interface cable. Replace the computer cover,
and reattach all cables and power cords. Turn on the computer, restart the
operating system, and attempt to open the loading tray by pressing the
Open/Close button. If the tray fails to open and the busy indicator does not
light, turn off the computer and try using another 15-pin dc power cable.
