Acer power cord

sometimes taking out your battery then plugging in the power cord will do it.....acres have a habit of doing that

Acer laptops allow you to take your work and entertainment on the go.

You can work on a presentation during a long flight or watch a DVD in the middle of a park.

Acer laptops can do this because they are powered by batteries, allowing the laptop to run without having to be plugged into a power source.

Normally, the battery can be recharged by plugging the laptop back into a power socket.

But certain problems can keep the battery from charging.

Electrical Connection

For laptops to charge, they need to be connected to a power source.

Although it may look like you have the cable plugged in correctly on the Acer, make sure that the cord is firmly plugged into the power socket.

There should be a light on the Acer keyboard as well as a power symbol on the taskbar for your operating system that tells you whether the laptop is running off electrical or battery power.

If it is plugged in, make sure that this icon shows that it is on electrical power.

Also check the socket where the Acer is plugged in and make sure that it isn't turned off at the main circuit breaker.

Battery

Turn the Acer over and make sure that the battery is properly placed in the battery compartment. Most laptops will have locks that keep the battery securely in place.

These locks can sometimes come loose.

Use a piece of strong tape as a temporary measure to keep a loose battery in place.

Clean the terminals on the battery to ensure that there is a good connection.

Remove the battery from the battery compartment.

Apply rubbing alcohol to a lint-free cloth. Rub this cloth over the shiny metal terminals on the battery.

Over time, batteries lose their ability to be recharged.

If neither of the aforementioned steps works, you may just have a bad battery.

Check with Acer or other vendors to find a replacement for your model.

BIOS Update

The BIOS (Basic Input Output System) controls a number of basic functions for a computer, such as assigning the hard drives and other system functions.

The BIOS also controls the battery charging function.

Certain Acer models have a bad BIOS that operates the computer normally but doesn't charge the battery.

To solve this problem, you need to perform an operation called Flashing the BIOS where you download a new version of the BIOS and upload it to your Acer.

Check on the Acer support site to see whether your computer model could possibly be affected by this.

Adapter

The power adapter, the part that plugs into the Acer from the power socket, can go bad.

Check for a power light on the adapter.

If the light is not lit, you probably have a bad adapter.

Replacement adapters can be purchased from Acer or other online vendors.

Batteries only have a useful life and once it is used up they have to be replaced.

If you can get on the laptop and work without any problems using your AC Adapter and Power Cord then the battery is definitely dead and needs to be replaced.

If you have problems using your computer using the AC Adapter and Power Cord then either your Power Cord is Bad or the DC Power Jack where the power cord plugs into the computer is bad. If either of these two is bad they will not charge a Good Battery.

Check your DC Power Jack which is where the power cord plugs into the computer is bad. Take an ink pen and push the tip inside the jack and see if the little pin wiggles, if so the jack is bad. You'll have to take the laptop apart to fix it. Most times it is soldered onto the motherboard, so you will have to desolder the old and solder a new one.

The battery isn't charging, from what you describe. Sounds like a bent pin, or a bad charging circuit. Waranty should cover, unless it was dropped or 'abused,' assuming that it was a new present. Take a quick look at the battery connection.

when you plug the power cord check and see if the battery shows that its charging ,if the charge level is low allow it to charge fully ,after its fully charged remove the power cord and see if it will go of again .if it goes off then you know the battery is dead if not it might be of low charge or not properly fixed.hope this helps

Take out the battery and make sure you can turn on the laptop with just the AC Adaptor hooked up.

If you can then you know the AC Adaptor is good. Try another known good working battery in the laptop, if the battery charges then you know that the old battery is bad.

If the laptop doesn't charge with a know working battery or a new one then you know that the motherboard is bad.

Here is another thing you can try. Unplug the power cord, and then remove the battery. Press the "Start" button and hold for 5 seconds. Replace the battery back into the computer and plug in the power cord. Start the machine and see if the low battery message still comes up. Sometimes the program that monitors the battery status gets confused. Doing the above should straighten it out. The Acer should start up and the AC power light should be lit. Look down in your task bar for the battery Icon or go to Battery Status in Control Panel and see if it shows that the battery is charging. Even newer batteries can go bad (rare) but if this is the case and a cell has shorted out in the battery, then your only recourse is exchange under warranty.

Motherboard is bad and will have to be replaced unless of course the AC Jack on the back of the laptop is loose. That would cause the ac adapter not to charge and then you would have to take the motherboard out and put solder on each leg on the bottom of the ac jack to make sure it stays in place then the ac adapter can charge the battery properly.

Even going thru the solder method the motherboard could still be bad and have nothing to do with the ac jack.

it could be a short in the power cord or a lose dc jack in the back. what model acer is this for as power packs for them dont cost to bad.

remove the battery and see it the power comes on, if so bad battery, check the connector where the power plugs into the laptop, sometime this breaks or has a cold solder joint, you can test this by wiggling and looking to see if the power lights up. last and worst case is a bad main board.
