Try using another ac adapter, sounds like the adapter is failing. You can either ask if one of your friends has the adapter with the same connector and voltage (check that the wattage of the adapter is sufficient) or if someone has a universal ac/dc adapter for the test. If the laptop starts normally wiht another adapter, then get a replacement adapter and you are good to go.

SOURCE: Laptop stuck in sleep / hibernate mode??

Try holding the power button down for at least 10 seconds, that should turn off the laptop completely. Then press the power button again to turn it on. Hopefully it will boot up.

Need to fix G62 computer:will not start


"Worked in the past, doesn't work now", That's sort of the definition of a failure. Has the laptop been dropped? What does the laptop when you try to start? Do you see LED"s blink? Fan spins? HHD LED blink? Battery light on? Has the AC jack been damaged due to pulling on the cord? Did you try a cord/charger with the EXACT same power spec? Test the DC volts at the laptop cord plug with a multimeter. Reseat the Memory mods. May be a HDD failure? Post results

Wont start up


Remove the battery and AC Adapter cord, and press and hold the power button for 30 seconds. Then, without replacing the battery try plugging in your AC Adapter to see if you get any love. If that doesn't work, remove the AC adapter, reset the board again, and this time hold the power button down as you plug in the AC Adapter cord. If you still don't get any lights, you could try removing your memory, reset the board, replace the memory, plug in the AC Adapter, and try one more time.

If all of this fails...you should take advice from experts,call at-http://www.vtechsquad.com

Hi,

The middle blue led is the charging indicator, sounds like you have (at least) a bad battery, remove it, plug in AC and try again, if no good, remove the HD and repeat, if no good, remove/replace the ram and repeat, if still no good, your mainboard is cooked.

Thanks,

Adam.

Battery has gone dead. When I plug the A/C cord in the light on the charger immediately goes out and won't charge battery.


try connecting ac adapter alone without the laptop, check if ac adapter light will stay green or blue.
try another power outlet using the ac adapter alone without the laptop check if the ac adapter light will stay as green or blue. if all fails replace ac adapter.

if ac adapter stays green or blue try connecting to the laptop without the batt, check if the ac adapter light will stay on, if yes then try connecting ac adapter to laptop with the batt plugin check if the light stays green. if not update the BIOS. if fails replace motherboard.

DELL Precision M65- cannot turn on. Even take off batt then turn ON, or using adaptor without battery still cannot turn ON. The LED light is ON but no visual/screen. Please help. Many thanks...


Hi,
Verify the AC power adapter displays a solid green or blue light. Older Latitude™ C Series laptop computer AC adapters may not have a light.
Run the diagnostics on the system as follows , connect both the battery and the Ac adapter before running the diagnostics

  1. Ensure the system is powered off.
  2. Remove all external peripherals.
  3. Press and hold the <Fn> key on the keyboard.
  4. Continue to hold the <Fn> key while pressing the power button.
  5. Release both buttons.
  6. Note which lock LEDs are lit (lock LEDS are next to the power button)
And proceed with the troubleshooting steps listed below

No power to monitors, but blinking led on ac adapters.


Hi...there,
Try replaced with a new AC Adapter. If it still the same...then you got a busted backlight inverter. To order a new AC Adapter go to this site @ www.3rd-rocks.com click on lcd parts. have a nice day!

HP DV2036ea i have a blank screen on the computer


Hello there

Description.

When pressing the notebook power button nothing is displayed on the screen or display. The cause of this problem may be a failed AC adapter, the memory modules (RAM) need to be reseated or a failed notebook system board component which will require an HP certified repair.

Below steps will assist in identifying the cause of the problem and suggest the best solution. Test the AC adapter 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 to start the notebook PC.
If the notebook does not start or the display is blank then check the power indicator light or power socket LED. Check the power indicator light or power socket LED On newer models of notebook PCs, there is an LED or indicator light around the power socket on the notebook. Check to see if this light is on or off, when the notebook is plugged into AC power.The power indicator light or power socket light should turn on when the AC adapter is connected.

  • If the light does not turn on then the problem is most likely related to the AC adapter or the electrical source in your home or office. Go to the Light does not turn on section on this page.
  • If the light does turn on but the notebook does not start or the there is a blank screen then continue to the Light does turn on but the notebook does not start section on this page

The light does not turn on when the AC adapter is connected 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 power cord to the wall outlet.
    • The connection into the power adapter from the power cord.
    • The connection from the AC adapter to the notebook power socket.
  3. Press the power button again to test the notebook PC.
If the power indicator light still does not turn on, then the AC Adapter needs to be replaced. Contact HP Service and Support for further assistance. Power socket LED or power indicator light is on but the notebook does not start If notebook power indicator light (LED) is on, the AC adapter is working correctly. The problem is a result of a hardware failure in the notebook itself. In some cases, reseating the memory module (RAM) may solve the problem.
