Suspend or Stand by option missing from Shutdown menu

By: Arie Slob

To recover the Suspend or Stand by option on the Shutdown Menu:

  1. Start the Registry Editor
  2. Go to HKEY_LOCAL_MACHINE \ System \ CurrentControlSet \ Services \ VxD \ Vpowerd
  3. Verify that the data value of the Flags value is greater than or equal to 200. If it is, modify the data value of the Flags value by subtracting 200 from the current value
  4. Set the SuspendFlag entry to 0 (if it is not already 0)

The suspend option disappears when the machine fails to resume 2 consecutive times. Resetting the registry values will bring the option back. It would be valuable to know exactly what is causing the machine to fail to resume. There is an APM troubleshooter available on the Win98 CD-ROM in the \ tools\ mtsutill \ pmtshoot folder, but a more recent version can be downloaded from Microsoft [157 KB].

Check if Advanced Power Management (APM) is configured properly:

  1. Select Start > Settings > Control Panel, and double-click System
  2. Select the Device Manager tab, and double-click the System Devices branch to expand it
  3. Verify that there is an Advanced Power Management Support entry under the System Devices branch. If this entry is present, select it, click Remove, restart your computer, and then continue with step 4. If this entry is not present, use the following steps:

    1. Select Start > Settings > Control Panel, and double-click Add New Hardware
    2. Follow the instructions on the screen to finish the Add New Hardware wizard. If this wizard successfully detects and installs support for APM, do not continue with the remaining steps in this article. If this wizard does not successfully detect and install support for APM, your issue may be related to problems with your hardware, and you should contact your hardware manufacturer for further assistance

  4. Select Start > Settings > Control Panel, and double-click Add New Hardware
  5. Follow the instructions on the screen to finish the Add New Hardware wizard. If this wizard successfully detects and installs support for APM, continue with step 6. If this wizard does not successfully detect and install support for APM, your issue may be related to problems with your hardware, and you should contact your hardware manufacturer for further assistance
  6. Restart your computer, and then test to determine if the issue is resolved by selecting Start > Shut Down. If the issue is resolved, do not continue with the remaining steps in this article. If the issue is not resolved, continue with step 7
  7. Select Start > Settings > Control Panel, and double-click System
  8. Select the Device Manager tab, double-click the Floppy Disk Controllers branch to expand it, select Standard Floppy Disk Controller, and then click Remove
  9. Restart your computer. Note that when you do so, Windows automatically detects your floppy disk controller, and the SuspendFlag entries in the registry are reset

Note: for IBM ThinkPad 760:

IBM ThinkPad 760 series with Mwave/DSP (Audio/Telephony Features) installed models support Data Modem/FAX, MIDI/Wave audio, and CD-Audio features under Windows 95.

When you upgrade to Windows 98, your original Mwave/DSP program that runs on Windows 95 will not allow you to select the suspend/resume power management feature. After you install Windows 98 on your computer, run the Apmpatch.exe file. After you run this program, you can select the suspend/resume feature in Windows 98.

To run Apmpatch.exe:

  1. In the \ drivers \ pwrmgmt \ ibm directory, double-click Apmpatch.exe
  2. Follow the instructions that appear on your screen
  3. Restart your computer

The suspend/resume feature will work after you restart your computer.

This patch needs to be applied for Windows 95 preloaded models of:

  • ThinkPad 760C / 760CD
  • ThinkPad 760E / 760ED
  • ThinkPad 760XD
  • ThinkPad 765D
