Problem Cause and action
If you play the DVD Express with
Windows 98 or Windows 95, the “No valid
Disk/Drive found” message appears.
This message appears when you reboot or restart your ThinkPad computer with the
DVD-ROM left in the DVD drive. Remove the DVD-ROM from the drive and then
reinsert it.
If the problem persists, check the drive assignments. Assignments should not skip letters.
Suppose, for example, that you has assigned the hard disk drive as the C drive and the
DVD drive as the E drive, and nothing is assigned as the D drive. In this case, you would
need to assign the DVD drive as the D drive. To change the drive letter form E to D, do
the following:
1. Click Start, move the cursor to Settings, and click Control Panel.
2. Double-click Device Manager.
3. Double-click the letter currently assigned to your DVD drive (for example, E).
4. Click the Settings tab.
5. Select D in “Start drive letter” under “Reserved drive letters.”
6. Click OK and restart the computer.
The LCD resolution degrades when you
play a DVD movie.
Reset the LCD size as follows:
1. Click Start, move the cursor to Programs and ThinkPad. Then click ThinkPad
Configuration.
2. Click the LCD icon.
3. Click Enable in “Screen Expansion.”
4. Click OK.
