The adapter light is on when first plugged in but then when I connect the adapter to my laptop the light goes off and it doesnt supply any power


I suggest check out the AC adapter first.

1) When plugged into power, and plugged into the laptop, gently wiggle the cable from the AC adapter TO laptop.

Any change?

Do the same on the power cord TO AC adapter.

NO?
Go on.

2) The port on the laptop that the plug from the AC adapter plugs into, is the DC Power Jack.
If we are discussing an Acer Aspire 5738Z Notebook PC, the DC Power Jack resembles this one, (Not installed),

http://www.batterysupport.com/acer-aspire-5738-jack-p-302046.html

(When I note the DC Power Jack, it is this link I will be referring to )

As you can see there is a Center Pin. All power removed from the laptop, use a small wooden, or plastic object, and see if this pin moves around.

ANY perceptible movement means a bad DC Power Jack.

DC Power Jack checks out it's back to the AC adapter.
Wanted to perform the easy diagnosis first.

This will require a multimeter. An economical, yet fine for this test multimeter, can be purchased for as little as $8 to $12.

Available in a multitude of stores. An auto parts store is but one example.
Analog or digital is fine.

http://www.youtube.com/watch?v=bF3OyQ3HwfU

(Analog is fine. Some of us still like 'em)

DC Voltage is what you are going to check.

Black probe lead (Negative) goes in the Common port on the multimeter. (COM)
Red probe lead (Positive) goes in the Voltage port on the multimeter. (V)

If the multimeter just has symbols around the Function Knob, set it to the dotted line over a solid line, symbol.

The plug on the end of the AC adapter, that plugs into the laptop, has a center hole, and a cylindrical metal shield surrounding it.

The Center Hole of the plug is where the red Positive lead, of the multimeter goes.

The outside cylindrical metal shell is where the black Negative lead of the multimeter goes.

Hold the AC adapter plug in one hand, and at the same time hold the red Positive multimeter probe in the center hole.

With the other hand touch the black Negative lead of the multimeter, to the cylindrical metal shield on the outside of the plug.

You should read 19 Volts (DC), or VERY close to it,

I believe the AC adapter is the problem. Post back in a Comment as to your findings.

Acer 2480 2247 won't power up -no lights no nothing, pwr supply is not the problem,lid close switch isn't stuck ,pwr. on switch seems fine and power supply jack on motherboard is not broken


Remove the main battery and the power supply, allow several minutes to get rid of any residual charge, now plug the power supply adapter back in and press power "leave battery out" is there any change? if not! remove power supply, now! press and hold power for 60 seconds to reset the laptop. Next install main battery back in and the power supply adapter, power up! if no change, the motherboard is the problem.

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.

Acer Aspire 5570 will not charge.


Check to see if the DC Power Jack has not been burned or have been fried. If you already checked that out and there is no problem with the jack then it is the problem with the AC Adapter

ACER TRAVEL MATE 2480 WILL POWER ON BUT SCREEN REMAINS BLANK.


look close to the screen and see if there is a faint picture. if there is then read below for the issues and solutions that can cause this problem.

Issue 1: Lid button sticking

this is a common issue with this model that the lid button sticks closed. fiddle with it to see if it opens and the light comes on.

issue 2: Inverter for the monitor is bad

this is not to uncommon an issue when this problems shows itself. Laptops monitors light up with a fluorescent bulb. This is powered by an inverter. These can go bad and if they do the light will not turn on. you need to take this to a service station. i don't recommend trying to replace without knowledge of this. They are high powered and you can hurt yourself or damage the screen

issue 3: fluorescent bulb went bad

this is usually the least common but could have happened. usually happens when peopel spray their screen with cleaner and it drips down inside the bottom. This can be fixed by a service center but coudl get costly. best bet is buy a new screen.
