Erratic Serial Mice and ALR Powerflex Computers (64667)


The information in this article applies to:

  • Microsoft Windows 3.0
  • Microsoft Windows 3.0a
This article was previously published under Q64667

SYMPTOMS

You have an ALR Powerflex computer and you experience either of the following symptoms while using Microsoft Windows:

  • Your serial mouse has erratic mouse-cursor movement in any of the three modes of Windows.
  • Your serial mouse grabs items in Windows, even if you do not press any of the buttons on the mouse.

CAUSE

These problems occur with some older ALR motherboards.

To determine if a motherboard evision will correct the problem, follow these steps:
  1. Turn the computer off.
  2. Take the cover off of the computer.
  3. Look near the edges of the green motherboard for a white sticker. This sticker will contain revision letters or numbers (for example, "C-N").
  4. Look for a prominent period or a "bullet" (for example, "C-N.OP" or "C-N.").
NOTE: If you do NOT see a period or bullet, contact your local ALR dealer for a motherboard revision. If you DO see a period or bullet, a motherboard revision is not the solution.
