Question about Samsung SyncMaster 2493HM Monitor

1 Answer

If my computer goes to hibernate after not being used, normally I tap the keyboard and it wakes up and turns on the monitor. That doesn't seem to be happening. Even when I push the main power on off switch off on the computer it doesn't react. I have to shut off the power bar , then turn it back on then push the power button on the computer to get things started. The monitor may light up or not. Even if I am uding the keyboard the monitor shuts down and goes to black. I have tried putting it on my laptop, that didn't work. I've tried the main power on and off swithc at the back of the monitor, no difference. There does seem to be a slight popping noise from time to time in the back of the computer?? I do not have the speakers activated on the monitor. any ides?

does your monitor have an external transformer as the psu ?
If so, try disconnecting at mains for about 5 seconds and re-connect. failing that we'll need to dig deeper.

Hello,

It sounds like you have a monitor with a common problem. After a few years some LCD monitors will blow a power supply. The problem is caused by parts called capacitors overheating in the confined space of the monitor. If you are good at electronics repair/soldering you can usually fix the problem. Check out a few pictures on my web site www.ccl-la.com/badcaps.htm You can take the back cover off your monitor and look for the bad parts,replace any that look like the pictures and your monitor should work fine. The capacitors do need to be installed with the correct + and - connections, note the stripe on the old one and insert the new one the same way. Look in our monitor repair section for step by step repair guide for this model it should be the same power supply as the 930. If you don't want to try the repair yourself we offer a repair service for $35 plus shipping.

I hope this helps, if so please rate my solution.

SOURCE: Samsung SyncMaster 710N Monitor SLEEP MODE

Hello,

The monitor is not going to sleep the power supply board is shutting down. If you can solder you should be able to repair the monitor yourself. The problem is caused by blown capacitors on the power board. Go to our web site at : www.ccl-la.com/badcaps.htm We have pictures of what to look for. Open your monitor and look at the power supply board for any blown capacitors, replace all that you find. The replacement parts can be ordered from several places on the internet or we can supply them for you. The replacement parts will need to be high temp and will be marked 105c. The values you need to get will be marked on the sides of the ones you take out but will be something like 220uf, 470uf, or 1000uf etc. and then a voltage rating. When you install the new ones be sure to insert them with the polarity stripe going the same direction as the old ones come out. If you don't want to do the repair yourself we do offer a repair service for $35 plus return shipping. If you have any questions just let us know

I hope this helps if so please rate our solution.

I would say it is in the Hibernation Mode To get it out of this mode you need to go to your Control Panel, open "POWER OPTION'S" and deselect the Hibernation mode then reboot.

Hp550 computer not going to sleep mode properly


No matter which model of HP laptop you own, battery life is a big issue. Hibernation mode is designed to increase the battery life of your HP laptop by switching off the monitor, hard drive and other parts of the unit after they have been idle for a specific period of time. While hibernation mode works well most of the time, in some cases, your HP laptop may not wake from hibernation the way it should.

Docking Station Issues Many hibernation problems are caused not by the HP laptop itself but by the docking station to which it is attached. Some models of docking station interfere with the normal operation of the hibernation on the HP laptop. The easiest way to test this is to remove the laptop from the docking station and allow it to sit until hibernation begins. If hibernation mode works with the laptop undocked but not while docked, you know the problem lies with the docking station instead of the HP laptop. b> Remote Desktop Issues If you need to connect to your HP laptop from elsewhere, it is helpful to reset the power settings to the Always On mode before you leave your home or office. Many models of HP laptops do not wake properly from hibernation when users connect to them remotely using the remote desktop feature of Windows. When users connect with remote desktop, the program sends a signal to the remote computer that should wake it from hibernation and allow it to function normally. However, this process does not always work as intended with HP computers, so it helps to change the power settings to allow a seamless connection. Video Drivers Problems with HP laptop hibernation also can be caused by a corrupt or outdated video drive. HP laptops come with built-in video processors, and the drivers they use are installed during the initial setup of the unit. If there is a problem with that driver, HP releases an update, so if you see problems with hibernation, your first step should be to check for an updated video driver. b> External Keyboard and Mouse Sometimes the HP laptop does not respond properly and does not wake from hibernation when you use the built-in keyboard and touchpad mouse. The sensitivity of HP touchpads varies from model to model, and that sensitivity can be reduced over time. You can test for this problem by attaching an external keyboard and mouse to the laptop to determine whether that resolves the problem.

My HP w2007 has started clicking to Monitor Going to Sleep and then going blank. I have never known how to wake it up so I have to turn the whole computer off and restart. HELP


Hey there, Normally simply pressing a random key on your keyboard or moving your mouse should wake it up, if it doesn't though I think the easiest way to solve this is to simply turn off the sleep mode after x amount of time.
If you have windows 7, press the start button and type in "power options", go ahead and open power options and there you will be able to set the time it takes before your PC shuts down, and you can also set it to never.


If you still wish to use this feature but just want to be able to it's a bit tricky and it won't even work for all PCs but if the keyboard waking isn't working, then it's probably because your pc does have this feature. When your PC is off, boot it up again and enter the bios by pressing F10 i believe it is for HP. And somewhere you should be able to set which devices are allowed to wake up your computer, all devices are probably disabled now, so go ahead and enable the keyboard to wake up your computer. Now save and exit, and the next time your PC goes to sleep mode you should be able to wake it up by pressing a key on your keyboard.


I hope I was able to assist. If I was, please don't forget to rate this solution.

You might have put the computer into hibernate; have you tried pressing the power button? It should wake the computer up if it is asleep or hibernating. It is also possible that your monitor cable is unplugged.

How do I wake up the monitor when it goes to sleep when not used for a short time.


slapping it around usually works. "just a joke!"

tapping a few keys on your keyboard and moving the mouse will usually wake the monitor from sleep mode.

Dell E173FP Monitor requires unplugging/plugging back in to wake


Perhaps your computer is hibernating instead of going into standby which takes a little longer to wake up from. While you are playing plugs and cables it give it enough time to come out of hibernation.

When the computer is in this mode the USB ports turn off which disables keyboard and mouse so the only way to wake up the computer is to press the power button on the computer itself.

One tell tale sign a computer is in hibernation is that the power light on the computer will slowly blink.

I hope this helps.

How do I get a monitor out of hibernation mode? It is not responding and did not reset when I rebooted.


Try using the power button, which usually takes the computer out of hibernation. Also, the mouse and keyboard can sometimes wake the computer from hibernation as well.
If the computer is still stuck in a hibernated state, hold the power button in for about 5 seconds so the computer fully shuts down and power it back on.
Good Luck!

Hit the keyboard keys. It is better to just turn sleep and hibernate off and just use a screen saver or tun it off.
