Hi, i am facing the problem that when i plug in the AC adapter, but the battery is not charging ... the battery status light indicator keep breathing white and red light.... and everytime i turn on, it sait that the battery cannot be identified. i had just bought my laptop for 1 year. yesterday it just suddenly cannot charge the battery and can't identify it. what's wrong with my battery??

This is only the first of many things you may need to do to determine the fault. But it is a process for determining the exact cause.

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.

Check battery indicator. If OK, update BIOS. If no change, check battery bios info, if AC Adapter is incorrect, replaces it. Please comment if the information provided has been helpful for the improvement of my support assistance. Thank you and regards.

hi Jeanette,
If ur battery is aged more than a year then its better to replace it... but do try this first... First update the BIOS from support.dell.com... while updating make sure that the Ac adapter is connected k... after updating check the Battery status in BIOS also the AC Adapter status.. if AC adapter is connected and status is shown as Unknown pls contact dell tech support.. the dell tech support guys are truely genius they ll help u to replace the spoiled parts if any with in the warranty period..

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.

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.

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
   

follow this procedure:
1. unplug the ac adapter and keep it 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)

From the manual:

"Attach the barrel tip of the AC Charging Adapter to the AC Charging port of the POWER TO GO® and plug the standard two-prong plug into an appropriate, functioning 120 volt AC outlet. The red Battery Status LED indicator will flash, indicating a proper connection has been made and the unit is charging. The green Battery Status LED indicators will gradually light as the charge level rises. The POWER TO GO® must be charged for approximately 11-17 hours prior to first use. All Battery Status LED indicators will be lit solid (the red indicator will stop flashing) when the unit is fully charged.

plz try by resiting the ram, if the problem persist then you have problem in display adapter,send it to the vendor from whom you have bought

The problem could be your bezel.  Remove the 3 screws from the hinges from the rear and you will be able to remove the black strip above the keyboard (after removing the screws, make sure laptop is layed wide open)  once removed, press the button on the motherboard under where the power button is.  If the unit still does not power up, then your motherboard is bad and needs to be replaced.  If it does power up, you need to replace the bezel.
