Most former generation cards and motherboards in towers use the notorious PLCC (plastic leadless chip carrier) to mouont large scale integrated circuits. These vary in size from postage stamp to checkerboard squares, and their inherent design makes the socket bow outward, with chip mounted, on all four sides--just enough to compromise the middle contacts on all four sides. The best solution is to optimize what contact there is, by spraying around the perimeter of the socket where the contacts are with plastic safe lubricating contact cleaner and then re-seating the chip by pressing it into the socket with a firm thumb press; you'll feel it move. I do this as a matter of routine maintenance with every such I work on.

    If nothing seems to help, if you have an ionizer air "conditioner", turn it off and unplug your computer for several hours to a half a day. They can play whaley with digital circuits.

I) usually an computer enter's into power saving mode if computer monitor is not receiving any singals from the computer tower, so it has nothing do withur computer monitor(computer monitor is working fine), there is some problem withur computer tower.

ii) now try  removing all the physical connections going to computer tower(back side), wall socket  and replace them ....., (to avoid loose connections) 

   now see whether ur computer is turning on and working properly so that your computer monitor receive singals ....

  let me know what is happening

Thanking you

Acer pc and lg monitor blank screen says power save mode on start up, anyone know how to fix this?


Actually during start-up there is a slight delay before the HDD & OS is detected by the CPU. Normally all monitors slip into power saving mode within 10 secs of inactivity of either mouse or keystroke. This inactivity is read by the monitor which promptly switches to power saving mode. However the moment the HDD LED starts blinking, the monitor wakes up & starts displaying. This power saving mode in most of the flat screens is only associated with movement of mouse or keypad. This does not register till the CPU starts up & thats why the monitor switches over to power saving mode till it starts receiving signal from the CPU.
It is a normal behaveour, so don't get worked up over it, plus you can always hit the Auto set feature on the monitor after booting the PC completely. ( I think the time out for the monitor to enter power saving mode is only 10 secs). Hope this helps.

hi mylesj880,

Press del. or f8 to boot to Bios there should be an option for you to remove power saving mode. If none then you probably need to update the bios be careful when updating bioses.

Hope it helps. Feel free to ask

Monitor displays "warning pc entering power saving mode


Hello
Sounds like to power settings were set too low. Restart the PC, before it gets to Windows press F8. This will send the PC into SAFE mode. You'll get a menu of which SAFE mode to select, just select SAFE mode with networking. Once in SAFE mode, go to START, Control Panel, Power Options. From there select new settings. Since this is a desktop, I would make the settings very long. Good luck

My monitor shuts down after one second.


Dell monitors automatically go into power-save mode after a preset amount of time when the computer is inactive. The Dell monitor will go completely black, instead of showing a screensaver. This doesn't mean that your Dell computermag-glass_10x10.gif has shut down. Instead, this allows your monitor to essentially turn off until it's needed again. You can change how long it is before the Dell monitor goes into power-save mode by changing your display settings.
  1. Step 1 Press any key on your keyboard or move your mouse. Either will turn off power-save mode. Alternately, you can press the power button on your Dell computer tower or laptop.
  2. Step 2 Press any key a second time if the monitor goes from power-save to stand-by mode. Stand-by mode allows the screensaver to appear.
  3. Step 3 Enter your user name and password into the login prompt if your computer requires a login. Press "Enter" to begin using your Dell computer.
  4. Step 4 Change the display settings on your Dell monitor to prevent your monitor from going into power-save mode prematurely. Right-click anywhere on your desktop and choose "Properties." Click the "Screensaver" tab and press "Power." Beside "Turn off Monitor," choose a time amount from the drop-down list and press "Apply."
