SYMPTOMS

When you click Start and then click Shut Down on your IBM ThinkPad 760- series or 765-series computer with an MWave DSP (digital signal processor) device, the Suspend command may be missing.

STATUS

Microsoft has confirmed this to be a problem in Microsoft Windows 98.

  • ThinkPad 760C/760CD
