I plug my ac adapter in my laptop usually when you charge it turns the battery light in red then after few seconds turns to green! do you think the charge is not working?

Follow the steps given below. (Please be careful when handling computer electrical components like batteries and AC Adapters)

• Remove the battery and hold down the power button for few seconds (to drain all remaining power)
• Power up the computer without the battery with the A/C adapter plugged in.
• Wait for few seconds and plug the battery back in

After a few tries the computer should start charging normally. The amber battery stops blinking and turn green when fully charged.

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.

I would try a freh AC Adapter as it may well be the cause of your problems!

That means that the AC adapter is dead and the battery is out of charge.

The battery is critically low, indicating that it is not getting a charge from the AC adapter. If the system will not power on from the AC adapter, then the motherboard power connection is suspect.

Motherboards are about $100 on EBay

which green light?

light from the ac power adapter or the light from the battery?

if ac power adapter you are referring to try a diff power wall socket if ac power adapter still off then replace ac power adapter alone.

if battery light is off but the laptop works fine with ac adapter alone try updating the laptop BIOS.

if ac adapter light turns off when it plug to the laptop replace motherboard.

maybe your battery went wrong, or your laptop battery don't match your laptop.

it-battery hope to help you.

Faulty Battery.
Get a new one.


If that is not the problem check the ram.

Try this:

With the AC adapter and battery installed and it will not power up remove the adapter and the battery. Then plug in the
AC adapter after both have been removed for 30 seconds and let the laptop set for 30 seconds and then unplug the AC adapter and then slide in the batter within 15 seconds and try to start the laptop.

Its late, so just to make sure I'm not brain-dead basically your laptop runs fine as long as its powered by the AC adaptor but dies fairly quickly while running via battery. This is very typical of a battery that will no longer hold a charge, not normally a user repairable item. It could also be that the charging electronics (in the laptop) isn't charging the battery, again not a typical user repair job. About your only option short of taking it to the repair shop is buying or borrowing a battery as a test.
