Take out the battery and try the new adapter, if it doesn't turn on then take out the hard drive and the dvd drive. Then try turning on the laptop again with the new adapter, if that doesn't work then try the old adapter.

If your still not getting power make sure your hooking up the laptop to a working outlet to be sure its not an outlet problem.

At this point if your not getting power and you verfied you have a working outlet then this means the motherboard is bad and would need to be replaced.

My CTK 720 isn't powering on from the adapter anymore but battery power is working. I bought a new adapter but it still isn't powering on. Can this be repaired?


This could be a loose plug inside the unit or it could be a circuit that is bad. If the plug failed it is from physical damage from something like tripping over it or heavy use. That can be repaired by replacing the plug. If it is something like a component in the unit on a board then it becomes a little more involved.

My purchase of PDV880 8 in. did not have the ac power adapter included


I found a listing on "http://www.ebay.com/itm/9V-AC-DC-power-adapter-Venturer-PDV880-portable-DVD-/110624776686" for about $11 USD,

You may want to look at the specs on the back of the unit and try to match it up with a similar unit from a thrift store or such if you cannot contact the company for a new one.

Made pop noises screen flashed considerable hum then no power no sound no nothing


Hi,

This model no. is known for AC power adapter problem. Pop noises, flashes of the screen is an indication of out-of-regulation condition on its power supply. If there's no LED light lit, then high chance that the fault came from the AC power adapter.
This model no. used AC power adapter with a 12 Volts output feed to the unit. You have to confirm the 12V output using the multimeter set in DC measurement.
If the 12V output voltage is not present, then you have to replaced it with new one. This model no. is already discontinued, only substitution is available online which will work also for your unit. You may inquire/call Sears hotline no. (1-888-213-5824) to confirm and order the AC Adapter.
Please let me know if the Adapter is intact to assist you further.
Please rate only if you feel I've gave you the best answer. If you have any question, please let me know.
Have a nice day!

Unit will not come on-power ok ac to dc adapter ok


Great job on checking the power from AC to DC adapter. Also, make sure to plug the printer straight to the power outlet in the wall, bypass any surge device or power strip. Unplug and replug the power adapter in the printer, make sure it's properly secured and in the right position in the slot. Press the power button if needed. If this doesn't help at all, I strongly suggest you contact Lexmark Technical Support to further investigate the problem. I hope I can assist you more on this matter.

ZHow do I charge battery (new user)


just plug in your adapter that came with the unit.....leave it for the recommended time for charging and there you go.....if you don't have an adapter...you'll need to find out the required power that it needs and then purchase an adapter that will supply the necessary power....and also of course, the plug must also fit the receptacle on the back of your unit...with the correct polarity......good luck

I HAVE A ASPIRE 5520 IT WONT START THE FAN STARTS AND THE DVD BUT IT JUST KEEPS ON LOPPING


I had the same problem but what you can do is...

Make sure the ac adapter is correctly plugged into the notebook and into the power cord.

If everything is plugged in correctly and it still will not power on, follow these steps to complete a ‘power reset' of the notebook.
  1. Unplug the ac adapter. Keep ac adapter unplugged.
  2. Remove the battery and keep the battery unplugged.
  3. Hold the power button down for 15-20 seconds. (Nothing will appear on the display and none of the lights will light up.)
  4. Release the power button and plug in the ac adapter ONLY. (Please note that a power indicator light should be lit on the ac adapter when it is plugged in).
  5. Normally power on the notebook.
  6. If the unit does not power on, remove the ac adapter and insert the battery into the system.
  7. Plug the ac adapter back into the system, the battery charging indicator light will light up.
    If the battery charging indicator light does not light up, the ac adapter may not be providing proper power to the unit, and may need to be replaced.
  8. If its not the batery or AC adapter you might have to send it to Texas, just go to www.Acer.com
