When i open my acer the lights indicator has only blink not totally open the computer


Hello, Christopher.

The most common reasons for power issues are the battery, power jack and power adapter/cord.

Power off and remove the battery. If the laptop powers on with just the adapter connected, your battery is faulty.

If you move/wiggle the power adapter at the point where it connects to the laptop, and the power goes off and on, the power jack is the problem.

The power jack is inside the laptop and either needs soldering or replacement. If a power jack problem, it should be addressed by someone knowledgeable.

If no change, the power adapter is probably faulty and needs replacement.

Hope this helps.

My Acer aspire 4935 is not recognizing the AC adapter. When ever I shutdown the system and connects the AC adapter, it works and the charging LED lights up. Once I press the power button to boot the...


Problem description:The battery charges only when the laptop turned off. The battery charge LED lights up as normal and the battery gets charged to 100% while the laptop is off.
When the laptop is turned on, the battery charge LED goes off even if the adapter is still plugged in.
Possible cause:1. AC power adapter failure.
2. Battery failure.
3. Broken/loose power jack.
4. Motherboard failure.
Possible troubleshooting steps and repair solution:1. This problem could be related to a faulty AC power adapter. It's possible that the AC adapter doesn't provide enough power when plugged into the laptop. To find out if this is your problem, you'll have to test the laptop with another working adapter.Replace the adapter if needed.

2. There is a slight chance that you have bad battery. Test the laptop with a know good battery and replace the faulty one if needed.

3. The battery charge problem could be related to the power jack. Maybe the jack is broken or not making good contact with the motherboard. It is necessary to remove the motherboard and take a closer look at the power jack. Resolder or replace the jack if needed.

4. If the power jack is in a good working shape and new power adapter with battery do not fix the problem, most likely you have a faulty motherboard. Replace the motherboard if needed.

The battery is not charging


Hi

Turn the Acer notebook off by pressing the "Power" button. Remove any power sources connected to the notebook. If the notebook is open, close it.

Flip the Acer upside down and place it flat in front of you. Slide the battery locking mechanism to the right. The locking mechanism is diagonal to the lower left corner of the battery. While sliding the mechanism, slide the slimline battery out of the battery bay.

Insert the AC power adapter. The AC power adapter outlet is located toward the middle of the right side of the notebook. Attach the other end of the power adapter to a functioning electrical outlet. Open the laptop. Turn the power on. If the Acer notebook powers on, the AC power adapter is properly working. Replace the AC power adapter if the laptop does not turn on. Remove the AC power adapter and turn the notebook off.

Inspect the slimline battery. Look for signs of damage such as dents and corrosion. If the battery contacts appear to be dusty or have residue, gently clean them with an alcohol wipe or cotton swab dipped in rubbing alcohol.

Re-install the battery by sliding it back into the battery bay. You may hear a click or snap when the locking mechanism locks the battery firmly into place.

Plug the AC power adapter into the laptop. Leave the power adapter in the notebook for eight hours so the battery charges.

Remove the AC power adapter. Power on the Acer notebook. If the notebook does not power on, the slimline battery must be replaced. If it does turn on, the battery did charge.

Travelmate only powers up with battery inserted. But AC still charges battery. Orange light goes on and of


Sorry to tell you this but you may have a problem with the charging system. That will require you to return it to Acer or an Acer service center. You can also try this. I got this from Acers' travelmate support website:

If the notebook does not power on:

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.
You can aslo google your specific model of Travelmate to see if others are having this issue.

Notebook is not charging, even when the ac adapter is working.


definately sounds like your battery might have went bad on you. Try to find one that you know works and see what happens in your machine.
