You can eliminate the possibility of a faulty charging system by testing the output of your charger that connects with the laptop. You can do this by attaching one end of a bulb (rating approximates the voltage output of the charger) to one end of the charger (+ or -) and the other to the opposite end. Using a thin wire will do the trick. If it lights, then your charger is working. If it doesn't, your battery could be the likely problem.

Dell vostro 3500 shows battery connected but not charging and intermittently shoes no battery detected


Instructions

1
Determine if the laptop battery is defective. While less than 1 percent of batteries are defective, the possibility is still there. If the battery is new and only charges some of the way, it may just require a BIOS update to charge fully. New batteries that refuse to charge at all may be defective. Purchase a new laptop battery to replace the defective one.

2
Test the laptop power adapter to see if it's faulty. Run the laptop directly from the laptop power adapter and without the battery. If the laptop does not work with the adapter plugged in, the adapter is dead and you will need to replace it. The laptop battery may refuse to charge if the adapter is faulty. Charge the battery with the laptop turned off.

3
Insert the laptop battery into another laptop to test it. If the laptop battery charges in another laptop, the laptop's motherboard may be bad. Replacing a motherboard in a computer can be very expensive. If the cost to fix the computer is not worth the cost of replacing the motherboard, consider purchasing a new laptop.

4
Reinstall the battery to ensure all connectors latch properly. The latch mechanism that holds the laptop battery should click into place. If the latch does not close, remove the battery and examine the compartment for signs of damage.

5
Troubleshoot the BIOS to determine if there is a hardware problem. Turn on the laptop and immediately enter BIOS setup by holding down the "Del" and "F1" or "F2" keys, depending on the make and model of the laptop. When the BIOS screen appears, see how long it takes for the battery to charge down. If the battery does not last as long as the BIOS setup, a hardware failure may be the problem.

No battery is detected in dell 830


If the laptop battery is more than 3 - 4 years old then the battery could be worn out. Rechargeable batteries have a finite number of charge and discharge cycles and will lose their charge capacity over time, i.e. won't charge to 100% and gradually the charge reduces until the battery won't charge up at all. OR The battery shows a 100% charge but when the adapter is disconnected the battery drops off to zero capacity in a very short time. If the battery drops to an unacceptable charge level then the battery needs to be replaced. Rechargeable batteries will fail if stored in a discharged state for long periods.

My dell demension E521 is giving me a "alert system battery low" message. Any suggestions?


Check the batteries voltage and check to see if the battery is being supplied charge voltage when the computer is off. If both these are good then your low battery message is in error. No charge voltage would mean faulty charger and low battery voltage would mean faulty battery.

Dell E521 desktop computer will not load


Test all power and data leads that attach to your hard drive IDE,SATA

the leads from your MOTHERBOARD TO YOUR HARD DRIVE make sure they have secure dust free connections and are not faulty or just replace them they could be faulty


make sure all leads that are attached to your drives dvd\cd have secure dust free connections and are not faulty or just replace them they could be faulty a computer needs power and data to travel through every

working device and to continue its cycle and have an end so any faulty leads will end up with a computer error


even something as small as a faulty power lead or fan lead can cause you problems

computers need all of the data and electrical current to travel through every working device and to have an end to be able work properly

make sure ram modules and cmos batteries have dust free secure seatings and cmos battery has charge some motherboards cmos batteries are soldered in

make sure the CPU central processing unit has a dust free secure seating
you can usually do this by pressing the levers down at both ends of the CPU


hope this helps

If you remove the battery does the Laptop power on? If the answer is yes then the adapter is fine and the battery needs replacing. They generally last for about 2-3 years and then they die. If it is under warranty then return it to the seller and they will replace the faulty components.

My laptop wont charge


If your laptop isn't charging, it's usually one of two problems:

1) Your AC adaptor isn't working correctly anymore. It may be faulty, or may simply have endured all the wear and tear it can handle.

2) Your battery is either dead or dying, and is no longer charging correctly.

If the problem is your AC adaptor, a simple replacement will fix the issue. If the problem is your battery, then it gets a little more expensive (batteries usually aren't cheap).

Most laptops come with software to help monitor battery life and so on. Dell, for example, have their "Quickset" software, which can tell you if your battery is operating properly or not.

If you give me more details on the specifics of your laptop, I can help more. Manufacturer/Model?

Hope that helps.

My Kensington 90W power adapter will not charge my computer. It beeps when I plug in it and the battery does not charge.


Vscott481,

Im not sure what type of computer you have, but with the laptops I have had in the past, this is usually an indication that the battery has malfunctioned and will need to be replaced, the internal charging circuit and management system is no longer functional, or the contacts are dirty and the battery simply isnt able to charge becuase of it.

I do need some clarification...
A) Is the computer able to power up and run off of AC?
B) Does the battery have any charge at all, or does the PC list it as 0% or 100% (if the system boots)
C) If you are able to boot, and your battery is not depleted but will not charge, you shoudl follow proper battery maintenance guidlines, which includes cleaning the battery contacts that connect your cells to the laptop. Battery power is transferred through the contacts and keeping them clean allows for a more efficient transfer of power. The best way to do this is with rubbing alcohol and cotton swabs.

If this does not seem to solve a problem, you can take the system to a qualified professional and they can try and find if there are shorts in the sytem with an electrical tester.

I hope this helped,
Jem
