We’ve got a couple ASUS P5KPL-CM motherboards, and when we’d try to put them to sleep, well they’d wake right back up again. Immediately. Everything powers down, you get the click, then it immediately wakes from sleep. This happened both in Windows 7 as well as in Mac OS X Snow Leopard (a hackintosh install)
I wrote one before about sleep issues in Vista – It’s possible that a similar change in device manager would work in Windows 7, but here’s another way to fix it, in all your operating systems, for good:
It’s the little jumper you see here circled in green, located on your motherboard (I made sure to get the rear ports and CPU fan in the picture to help you locate it). By default, ASUS has in on the left 2 pins.
Pop it off and put it on the right 2 pins (as shown in the picture).
–
For whatever reason, ASUS is addicted to putting this jumper in the other position by default, which always causes problems with sleep. I don’t remember the specifics of what it does, but it’s got something to do with standby voltage being put through the USB ports.
In any case, both Windows 7 and Snow Leopard properly go to sleep after this change, and can still be awoken by hitting a key on your USB keyboard. If your P5KPL-CM doesn’t sleep, give it a try.
She was turning off her monitor, a 26" Vizio TN panel, manually & I think that may have caused it to fry. Now she has my old 26" Vizio. The new 28" Hanns-G replacement won't fit on her desk so I got stuck with it. ;) Costco actually gave me a full refund on the broken monitor & the new one came from Costco.com.
Thanks for posting the clear solution.
I thought my mobo died and it was this jumper... I have P5QPL-AM... And i guess all asus mobos have same thing... When in default position i.e. switched in pin 1 and 2, my pc would boot some time and sometimes wouldn't... Now in this config its working fine.. Thank GOD... Thanks to you too man...
Works for win 10
Works for P5KPL-AM SE with Win10x64

The monitor goes to sleep mode once I sleep the PC as well. When I wake up the PC, everything works (mouse, keyboard, fans, HDD, etc.), but the monitor stays in standby mode and doesn't wake up. When I force the monitor ON, it stays on black screen and after few second goes to standby mode itself.
The monitor is connected to nvidia geforce gt730 via VGA cable. I tried with another monitor with its own VGA cable and the result is the same issue.
This started since last December and until now the only possible action is to switch off the power of the PC and then to power on. Then, when the PC runs, the monitor is on too.
Through all the time I red and tried tones of suggestions: power plans, advanced power options, drivers, etc. and nothing helps.
Any help and ideas about how to fix this terrible problem?
Big thanks in advance!
However, since you said this only started in December, assuming you didn't change any settings that may have led to it, my thought would be either issues with new drivers, issues with a Windows Update, or the Windows install is broken. Also possible something in the background is trying to use the card when it goes to sleep and causing it to flake out (GPU mining or game related). A fresh format and re-install (using old drivers) would normally be the first thing I'd do to try and start eliminating possible causes, though on older hardware this can get risky if you can't get a hold of all the motherboard drivers you may need beforehand.
I work on my PC many years and I've never played with the BIOS and drivers. Since years ago the PC works flawlessly, therefore I didn't update drivers or whatever. I even didn't install Windows updates since maybe 2016 and everything was fine. Since the problem started, I checked every settings of GT730 in the Device Manager and couldn't see anything wrong. I've never used my PC for mining or games. I was thinking of fresh format and re-install, but this would take a lot of work and time and then if the problem appears again, it would be wasting of time.
By the way, a friend advised me to disconnect some components (the 2nd physical HDD, DVD, etc.) and then to power on the PC and trying to sleep and wake it up to see if the monitor will wake up or not. The idea is to see if the problem may be because of the PC power supply. And if the power supply is the reason, then how can it work fine when starting the whole PC but unable to power on the monitor after sleep only?!?
Also is it possible to be some capacitor or other element on the MB? I checked everything with a strong lens and nothing seems to be wrong or damaged.
Another idea of mine is if the problem is because of a virus, malware or whatever. I checked all my system, even in Safe Mode. I still have only the Avast Antivirus in the startup, no any weird processes in the Task Manager.
I also connected the monitor to my laptop via HDMI cable to test if it will wake up. Once I just closed the laptop (the screen down to the keyboard), the monitor went to sleep as well together with the laptop. Then when I opened the laptop, the monitor woke up together with the laptop. So the monitor is ok.
Of course, during sleeping, the monitor kept staying ON, i.e. doesn't go to standby mode as it should if it was connected via VGA cable. Let me know if I am wrong, but as long as I know and tested before, a PC can't let a monitor go to standby mode as if connected with VGA cable. Right?
Will a PC turn off automatically a monitor (sleep) via DVI cable or Display port-to-VGA cable or Display port-to-DVI cable?
As to VGA-to-X adapters, I don't know how DPMS translates - it's possible a passive adapter might not work. I've found DP-to-X adapters to be fickle to the point where I'll go to lengths to avoid having to use them.
To be clear, I'm using the terms sleep/standby/save interchangeably, but using them to mean the low power mode that tends to hit approximately 1 watt power draw.
