Question about Acer Aspire 3000 Notebook

1 Answer

When unplugged it goes directly to "critical battery"

Even after being plugged into the charger for hours it will not get a full charge. For some reason it will charge to like 7% or around that and not go above that and then when you want to unplug it to use it some where else it goes straight to "critical battery" and dies a couple minutes after using it while not being powered by AC power. Why does it do this? is there a way to fix it or is a problem with the computer??

Why wont battery charge on laptop


A) The Battery is old, and beyond charging

B) The AC adapter (Charger) may be bad, and/or one of it's cables may be bad. If there is no one to test it with a multimeter, take it to a computer repair shop, and have it tested.

If bad suggest you look around at prices on the internet, before buying one from the repair shop. (If offered)

C) The port on the laptop, that the AC adapter (Charger) plugs into, is the DC Power Jack. (May be labeled as DC IN )

This jack may be soldered directly to the motherboard, in the laptop, or is attached to a cable which plugs into the motherboard.

For the style that is soldered directly to the motherboard, it's solder connections may have received damage.
Normal plugging in, and unplugging, may have cracked it's solder joints.

Bad connection caused by cracked solder joints, could = no power to battery. (Even though the laptop May be receiving power)

If laptop operates fine on the AC adapter, but the Battery will not charge, the problem may be a power sensor chipset, on the motherboard. May require replacement of the motherboard.

{ This chipset senses;
A) When the battery needs a Full charge, or just a trickle charge.
B) When the battery needs No charge, and power just goes to the laptop.
C) When the Battery needs a trickle charge, or full charge, and the laptop also needs power }

AC Adapter issues Q & A.


<p><b>Laptop switching to battery while connected to AC adapter</b><br /> <p><b>Q.</b> While turned on, the laptop will switch to battery power even if connected with the AC adaptor (sometimes during boot-up, or after a while) until the battery drains out, he then goes to hibernation (the battery light is off). If no battery in the laptop, it will shut down, and the AC light will blink very fast. The battery (li-ion) will only charge up to 10%, where it then jumps right up to 100%, and will discharge from 100% to 90% then jump to 0%, go to hibernation, and fails to complete the process, shutting down. The adaptor makes a small "camera flash charging" sound, stabilizing at 19v. When charging, it repeatedly makes the "charging sound" Faulty AC adaptor? Or Faulty battery? Or Both?<br /> <p><b>A. </b>First problem: The laptop switches to battery power even with connected AC adapter. Most likely you have a faulty power jack. It's either broken or loose. It's a known issue with laptops and you can fix it by replacing/resoldering the power jack or relocating it outside laptop case.<br /> <p>It also could be a problem with the power cord. Find a multimeter and check the AC adapter. See if the power cuts off when you jiggle the power cord. If it does, replace the adapter.<br /> <p>Second problem: The battery will discharge from 100% to 90% and then jump to 0%. It sounds like a bad battery.<br /> <p><b>Battery charging light is on even when power adapter is unplugged and laptop is stitched off</b><br /> <p><b>Q.</b>The yellow light for battery charging does not go even after switching the laptop off and power jack is disconnected.

The output voltage MUST be exactly the same. If your laptop requires 18.5V you must use 18.5V adapter. The amperage should be the same or higher. If the laptop requires 4.74A adapter, you'll have to find an adapter which provides 4.74A or MORE. <br /> <p><b>While using AC adapter alone or battery alone, laptop works.

I tried to unplug the AC adaptor while it went down to 0%, then the power meter for the battery came back to normal 85%.<br /> <p><b>A.</b> There could be a few different reasons why it happens:<br />1. It might be an issue with the BIOS. Make sure the laptop has the latest version of BIOS installed, update it if needed.<br />2. It might be a software related issue.

My laptop is completely dead, fine yesterday. Today no lights, sounds nothing. I tried removing the battery , unplugging no response. Thanks,


Remove the battery for at least 3 minutes... Then put it back and then plug in the charger and switch on the charger. If the battery is completely drained, it would take a while for the charging to initiate. Please have patience and leave it on charging even though without the charging indication for at least an hour. After that still if the charging indicator doesn't lit, then its definitely your charger or laptop. You will need to take it to a service centre in that case.

I have a Dell XPS M1210 laptop for which I have just purchased a new 9-cell compatible battery. It worked great for a couple of hours, but now shuts off immediately when unplugged from the AC power supply....


You might want to try what I did when I had a completely discharged battery for my Dell Laptop. I attached the battery to the computer, make sure the computer is off and plug in the charger for a full twenty four hours (undisturbed). And this really worked. I had no problems with the battery. Good luck.

There is a manual for your armada, the battery is inside the hinge, and you put the charger in the hinge..not sure if it on left or right side of it
If the battery is healthy then it will be full charged in a couple of hours from emty to full, if the battery ise´nt that healthy, it can take 10-12 hours of more
