This could be a sign that your laptop is overheating. If you touch the laptop while it is running & you find it too hot, make sure that the fan is running properly & that the air ways are not blocked.
You can blow compressed air into the cooling vents of the fan. If you notice clouds of dust coming out, then it might be a good idea to disassemble the laptop, clean the fan & air ways, & reassemble it back. If the fan has failed & is no longer running, it might need to be replaced.

If none of this solves the problem, or is not the case, then you might have a bad motherboard

My 32inch lcd tv keeps flickering it started all the sudden


TRY THIS

    • 1 Turn the TV off with the front-mounted power button, not the remote. Unplug the TV's power cord from the wall outlet. Let an hour pass before plugging the cord back into the wall outlet. Turn the TV back on with the front-mounted power button and wait until it has fully restarted. Bring up a TV channel to see if the image being presented on the LCD screen is no longer flickering. A momentary power surge can cause the circuitry inside the LG-brand LCD TV to function erratically.
    • 2 Unplug the video cable from the video connection on the back or side panel of the LG TV. If more than one video cable is connected to the TV, disconnect all of them. Disconnect the other end of the video cable from the video source device that it's attached to -- a DVD or Blu-ray player, or a satellite receiver or cable box. Blow off the connections on the video source device and on the back or side panel of the TV with bursts of compressed air. Reinsert one end of the video cable into the video source device and the other end into the video input that it was connected to. Turn the TV back on with is remote to see if the picture is now free of flickering. A loose or partially connected video cable can cause the LCD TV's screen to flicker when presenting an image.
    • 3 Turn the TV off and unplug its power cord from the wall outlet. Place a power conditioner next to the wall outlet. Plug the power conditioner's power cord into the wall outlet. Plug the TV's power cord into one of the AC sockets on the power conditioner. Turn the power conditioner on. Turn the TV on to see if the picture is now free of flickering. The RF signals in the electric line that the LG TV is drawing power from can cause flicking through interference patterns being generated.

Inspiron 2305 power cord doesn't turn the desktop on


After connecting the AC adapter to a wall outlet and to the computer press the power button the right side of the inspiron. The button itself should then lite up white if the power adapter is good. If not, check the power outlet you are using. Plug in something else and see if it works on this wall outlet. Some outlets are connected to a wall switch. If its still a nogo you may need to replace the AC adapter.

No power. Will not turn on


Not intended to offend;
1. If using A/C (house electrical power), please check if electrical wall outlet is active. Attempt to plug-in another electrical device such as a lamp, clock, radio, etc.. If the electrical wall outlet has top and bottom plugs, try the top and then the bottom plug to see which one works. Sometimes, the top outlet will not work, yet the bottom outlet does work. The wall outlet should be replaced by qualified technician.
2. If both outlets do NOT work, and the outlet is GFCI breaker protected, maybe pressing the RESET switch on the outlet will power-up the outlet.
3. If the outlet is NOT GFCI breaker protected, check your electrical fuse box for a tripped fuse. Sometimes, a tripped fuse is NOT visible. May have to trip the specific fuse or all fuses to off, then back on. Recheck the wall outlet.
4. Once your know the outlet is live, check the power cord (a/c adapter for laptops) to make sure they are securely plugged-in to both the wall outlet AND the PC or Laptop.

Will need more information once the above steps are taken:

Is it a Desktop or Laptop?
Make and Model (if known)?
Any lights (glowing) on the desktop or laptop?
Any lights on the A/C adapter if its a laptop?

It doesn't turns on


can you be a little more specific as to symptoms? any lights come on? do you get any beeps? are you plugged into a power strip? have you tried a different outlet, or cord? it doesn't turn on is very vague, and doesn't really tell us anything :) please be more specific

Locks frequently and restarts sometimes all by itself. Parts of the screen regularly skews in triangular shapes.


  • Verify that the power outlet you're using is good and your power cable is firmly connected to the wall outlet-if using a surge protector, be sure that it's firmly plugged into the wall outlet. Also, try temporarily plugging directly into the wall outlet to eliminate any issue with the surge protector; plug a different electronic device into the same wall socket to make sure the socket works, and also try the iMac's power cable in a different wall outlet.
  • Make sure the computer's power cable is firmly connected to the computer.
  • If any external devices are connected to your iMac, disconnect them and try to turn the computer on again. If the iMac will power up when those devices are removed, but not when they are connected, contact the manufacturer of those devices for assistance.
  • Try resetting the iMac's SMC
  • Remove and reinstall the SO-DIMM memory modules, located in the bottom of the computer.
  • Resetting the SMC for Mac Pro, Intel-based iMac, Intel-based Mac mini, or Intel-based Xserve

    1. Shut down the computer.
    2. Unplug the computer's power cord.
    3. Press and hold the power button for 5 seconds.
    4. Release the power button.
    5. Attach the computers power cable.
    6. Press the power button to turn on the computer.

Try connecting the TV directly to a different wall outlet and check. If the issue persists, try power resetting the TV. Turn Off the TV and remove the power plug from the wall outlet for 1 minute and reconnect it and check the operation. If the issue persists, then the TV may require service.

Follow the steps below to determine whether the problem is related to the AC adapter or your notebook system board:
  1. Remove the battery and disconnect all external devices from the computer.
  2. Hold the Power button for several seconds, with all power sources removed. This drains residual power from the system, and may correct many problems.
  3. Connect the AC adapter to a wall outlet and plug the other end into the computer.
  4. Press the Power button .
  5. Is the Power indicator light (LED) on or off?
****If notebook power indicator light (LED) is on, the AC adapter is working correctly***
If the power indicator LED is off, the AC power adapter may need to be replaced. To determine if the AC power adapter needs to be replaced follow the steps below:
  1. Ensure that the AC adapter is plugged directly into a known working wall outlet.
    NOTE: To check the wall outlet, plug in a different known working device like a light, radio etc.
  2. Check all of the following connections:
    • The connection from the AC adapter to the wall outlet.
    • The connection into the power adapter from the wall outlet.
    • The connection from the AC adapter to the notebook.
  3. Press the power button again to test the notebook PC.
  4. If the power indicator does not turn on, remove the AC power adapter from the notebook PC and re-insert the battery. Then press the power button. If the power indicator light still does not turn on, then the AC Adapter needs to be replaced.
*****Reseating the RAM may resolve this issue.****
Step 1 - Remove the battery
  1. Slide and hold the battery release latch to the unlock position.
  2. Use your finger to lift the battery up and out.
Step 2 - Remove the memory module
  1. Locate the memory module cover on the bottom of the notebook.
  2. Remove the screw that covers the memory module.
  3. Use your finger or a flat head screw driver to lift the inside edge of the memory module and remove it.
  4. Push both tabs outward simultaneously to release the memory module.
  5. Grasp the memory module by the edges and pull gently to remove it.
  6. After removing one module, replace the memory expansion cover and then replace the screw.
Step 3 - Replace the battery
  1. Insert the battery into the notebook.
  2. Push the battery into the base enclosure until you hear a click.
  3. Connect the AC adapter and turn on the notebook.
fter the memory is reseated, connect the AC adapter and turn on the notebook. If the notebook boots normally and the Windows desktop appears no further action is needed. If this problem re-occurs often, contact an HP Support Specialist to schedule a repair.
