Re: monitor goes to sleep no input signal only 1 mo old
Normaly the monitor is not picking up the signal from the PC, it could
be VGA cord is not connected, faulty, or the video card is faulty,or
the monitor is not compatible to the PC. It could be one of my
suggestions. Trouble shoot by connecting your monitor to another
working PC and see what happens.If not the VGA cord is faulty and not
picking up signal from the PC. Hope it helps.

If the monitor is going into sleep mode the normal power led will change to another color. This indicates loss of video signal or possible out of range resolution. If the picture goes dark and the power lite stays on, you have a backlight malfunction. It can be bad capacitors causing an inverter power fault or it may have worn out backlights causing a shutdown condition. Monitor Mike
that is the problem of cpu not a monitor to confirm disconnect signal cable and power on. monitor will show "no signal check signal cable" it means that monitor is ok and fault lies in cpu .then open the cpu and disconnect ram and listen the beep. contineus beep should be heard then ram is faulty replace it. if no beep heard then motherboard is faulty .
I have called HP Technical Support 6 times about this issue and have logged at least 14 hours into the issue. The things they have done are turn all sleep settings in the "Power Options" in the control panel to "never". The problem persisted. Today, they sent my problem to the complaints department, so maybe they will have the authority to do something for my 5 week old setup.
For me, the monitor was in the "other devices" part on the device manager (go to start menu and type device, and the device manager will show up). I went to HP's website to the support and drivers spot and found a patch for the My Display program. This will allow you to uninstall your monitor, just right click the monitor under "other devices" and click uninstall. After you uninstall, restart and your computer will recognize the and put it under "monitors" in the device manager with the updated drivers. After I did this, the monitor hasn't gone to sleep.
