Lf flatron w2253tq goes into sleep or hibernation and does not wake up. i must power the computer down and restart to get the monitor working.

putting a computer to sleep is not the same as hibernation because sleep mode still is technically powered on it's just in a relaxed state or low-powered state whereas hibernation takes everything that's in Ram writes it to hard drive and then completely Powers down hope that helps

Sleep mode on a Windows 7 PC saves power without you having to turn your computer off and without losing any work.

Whether you have a laptop, desktop or workstation, putting your computer into sleep mode will lower your electric bill and save money! Click the "Start" button in the lower left corner of your desktop. In the lower right corner of the Start menu, next to the "Shut Down" button, is a button labeled with a small, right-pointing arrow.

The problem is in the power supply board, caused by one or two bad capacitors that have become open, sometimes they bulge at the top when leaking.

If you use Windows 7, u might have hybrid sleep activated. This is similar to hibernate. When u choose SLEEP, your computer goes to hibernate. Sometimes this hibernate just hangs. You have to reboot computer.
Try pressing the power button for several seconds (10-15). It should power off the laptop.
If not, unplug the charger and remove the battery for a few minutes. Then try to start it up again.

Is the monitor connected to the computer using a VGA plug (a smaller one, with 15 pins in 3 rows), or a DVI plug (wider one, with flat pins in 2 rows)?

From what you write, your monitor is switched to the analog input (VGA). It doesn't sense any signal on that input and hence goes to power down mode.

You need to go to your monitor's on-screen menu and select the digital input - you should see the picture then.

I suggest to mess around with the monitor buttons and see if you can disable it from sleeping from there. If not then try enabling it to sleep on your computer settings. A good restart after any changes is always helpful.

press and hold the power button down for about 5 secs. The computer will shut down. Restart it and right click on the desktop, go to properties then look for screensaver tab , then choose power options, click on hibernation tab at the top and uncheck enable hibernation. Or choose stanby options and choose a longer time before the computer goes to sleep.

I have an LG Flatron 19" black w1952TQ that I bought on 2 Apr 2008; when it goes into sleep mode, will not recover. Did the online troubleshooting, reseting things, unplugging/replugging all cables, nothing works except restarting the computer, and that only works until it sleeps... Read more

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