Re: Monitor signal sleep

Recommended Posts

Windows opens, but after a while the monitor displays the message

Most likely the computer has entered sleep mode. To bring the computer out of sleep mode, use the following steps:

You may try the following steps and check whether you can fix the issue.



Method 1: To bring the computer out of sleep mode

1. Move the mouse or press the Spacebar.

2. If the computer does not wake, press the keyboard Suspend button. You may need to press the Suspend button on the keyboard twice (the suspend button has an icon that looks like a quarter moon).

3. If the computer still does not wake, press the Power button on the computer case for one second and release.

4. If the monitor does not wake, restart the computer and turn off suspend mode:

NOTE: Turning off suspend mode does not solve the problem, but it will help you determine if the problem is related to suspend mode or something else. Steps for Windows Vista :

a. Wait until the hard drive activity light on the computer is not lit and then press and hold the Power button on the computer case until the computer turns off.

b. Wait 5 seconds and then turn on the computer by pressing the power button again.

c. Click Start, Control Panel, System and Maintenance, and then click Power Options.

d. Select High performance, and then click Change plan settings.

e. Change the settings to Never.

f. Click the Save changes button to accept the changes, and then restart the computer.

5. Use the computer with the power settings turned off to see if the message continues.

• If the message opens after a software program is opened, such as when starting a game, the software is forcibly changing the display resolution to a mode that is not supported by the computer and monitor. Do not use the software or change its video settings. • If the message opens after certain period of time when the computer is not in use, the problem is most likely being caused by a screen saver. Turn off the screen saver to see that the problem no longer continues. If the above steps don’t work, then you may refer the following HP support link and try the steps provided

Method  2:Also make sure that the Display adapter is up to date.

1. Open Device Manager by clicking the Start button, clicking Control Panel, clicking System and Maintenanceand then clicking Device Manager.

If you are prompted for an administrator password or confirmation, type the password or provide confirmation.

2. In Device Manager, locate Display Adapter you want to update and then double-click the device name.

3. Click the Driver tab and then click Update Driver and follow the instructions.
