The battery indicator flashing when plugged in to electrical plug means your battery is completely dead and won't charge. You're computer should run with just the power cord. Your power cord most likely needs replacement.

If you know anyone with the same model of laptop ask if you can borrow their power cord and/or battery to test it out. It is rare for the problem to be the motherboard, though it does happen.

It may just be the power cord at fault as the computer should run without the battery, so you should replace the power cord, as it is probably the reason the battery is completely dead.

If the battery is at least a year old I would replace it since they generally don't last too much longer than a year.

Why is New Samsung computer battery not detected?


Step 1:
Computer Won't Recognize a Battery While desktop computers are plugged directly into an electrical outlet to obtain power, laptops rely on a battery and power cord in order to be charged. If your laptop suddenly stops recognizing this battery pack, however, it could jeopardize your ability to charge your computer and ultimately work on it at all.

Inspect the Battery With the battery unplugged, carefully examine your laptop's battery, both the battery unit itself and any cords or plugs attached to it. Make sure the battery's case is not cracked or damaged. Look for fraying cords and bent prongs on the plug. Any of these issues could cause internal damage to the battery itself, the cable or the plug, which could interrupt the flow of electricity between the battery or electrical outlet and your laptop. If your laptop is still under warranty, you may be able to get a free replacement for a damaged battery or cable. b> Check The Port b> Damage to the port on the back of your laptop the one into which you insert the power cord could cause your laptop not to recognize your battery or any cables attached to it. Turn off your laptop and turn it around so you have a clear view of this port. Using a flashlight to illuminate the port, inspect it for any dirt or debris that may have become jammed inside; gently remove any debris with a small cotton swab. A bent prong could also interrupt the circuit, making it difficult for the battery to transfer energy from the power cord to the laptop; straighten a bent prong using needle nose pliers. Avoid making invasive repairs, especially if your product is under warranty; any damage you do to the laptop in an effort to fix it could nullify the terms of your warranty. b> Wrong Kind Of Battery b> Some brands of laptops, such as Dell, will not recognize a battery that wasn't manufactured by the same company. To make sure that your battery is compatible with your laptop, consult your laptop's user guide for battery specifications (these will vary based on make and model of your laptop). b> Dead Battery b> Laptop batteries have a limited lifespan. After so many charges, they may be unable to transfer enough power from your electrical outlet to your laptop. When your battery reaches this point, a replacement may be your best option. b> Laptop Update b> Updating the "BIOS" on your laptop can help the unit better detect and recognize external hardware such as a battery. BIOS which stands for Basic Input/Output System assists in booting up your laptop, and helps run every function until you turn it off. Computer manufacturers release BIOS updates for their products routinely; these updates can be downloaded from the company's website as ".exe" files. Run and save this update on your laptop, then restart it to see if your laptop now recognizes the battery. Mac users can reset the laptop's System Management Controller (SMC). Apple reports that sometimes, otherwise unexplained errors pop up in the laptop's system, including problems with the battery's ability to charge. To reset the SMC, turn off the laptop and remove the battery. Hold down the "Power" button for five seconds and release before plugging the battery back in and turning the laptop on.

Even when laptop is plugged into an electrical outlet, it will suddenly think it is not and drain the battery power..the indicator lights will flash and battery power will drain.


There may be a fault in the laptop's power supply adapter.

Try testing its rated output voltage versus the actual with a multimeter.

If the adapter comes in 2 sections, 1 cord from the wall to the adapter, and then the adapter to the laptop, be sure to test both sections.

Replace the adapter if required.

Also check that the connection socket where the power adapter plugs into the laptop is not loose and preventing proper electrical contact.

Good luck.

Seems more like a problem with the power receptacle where you plug the power cord into the laptop.In order to fix this problem, you will need to disassemble the unit to get access to the motherboard & replace the power receptacle with a good one.

Won't turn on even with power cord plugged in


By dumping the power while running you have trashed your Operating System or blown up the Ram

Insert your OS disk and see if it comes to life , if it does then you may have to try a repair from the OS installation CD

If you have popped the Ram then the only solution is to get it checked out on another PC

Toshiba satellite A210 11-P crashes when i disconnect the power lead


From Toshiba, try step-charging the battery or Battery conditioning procedures:

Batteries don't last forever. All types of batteries gradually lose their ability to hold an electrical charge as they age. Eventually, the computer's battery charge indicator may show that the battery contains less than a full charge, even though the battery has just been fully charged. The computer will then not run for as long a time from the battery as when the battery was brand new.
You may prefer to simply replace the battery if this happens, but you may also wish to try 'step-charging' the existing battery per the following instructions.
This procedure should work for the battery in any Toshiba notebook. Follow it only when you find that the computer will run from the battery for just a short while.
Check the User's Guide for more specific information about charging the battery in your computer .

Procedure

Step-charging the computer's battery

  1. Unplug the AC adapter from the computer, and turn ithe computer on. Let the computer run from battery power until the computer turns off, indicating that the battery is fully discharged. Time this interval, but not with a software clock running on the same computer.

  2. Remove the battery pack from the computer.

  3. Unplug the AC adapter from the computer.

  4. Wait at least 30 seconds. The first time through this procedure, use a soft cloth to wipe the battery pack's contacts and the AC adapter's plug.

  5. Re-insert the battery pack.

  6. Plug into the AC adapter into the computer again and check the fit of its plug in the wall outlet, making sure the connection is secure.

  7. With the computer turned off, let the battery charge until the battery status light or icon glows green, or otherwise indicates a full charge.

  8. Unplug the AC adapter from the computer.

  9. Remove the battery.

  10. Wait at least 30 seconds, then re-insert the battery.

  11. Plug the AC adapter back into the computer.

  12. Let the battery charge again until the battery status light turns green or otherwise indicates a full charge, again.
Repeat this procedure, starting from step 1, at least three times. Each time, check to see if the computer runs longer from its battery than the previous time.

Battery Conditioning:
IMPORTANT!!
Interruptions in the charging cycle can be responsible for an issue called "memory effect" which may reduce the battery's charging capacity. Whenever you suspect the battery performance is not at it's optimum you should try using the following "Battery Conditioning" procedure.

Before you start: Turn off your battery saving features temporarily.

***IMPORTANT*** Repeat the following steps 2-3 times!

  1. Unplug the power cord from the computer
  2. Turn the computer on and let it run until it shuts itself off.
    Note: Using the CD-ROM to play an Audio CD will speed the discharge.
  3. Plug in the power cord (While the system is off) charge the battery until the battery light changes from flashing green to solid green
  4. Remove the battery for 30 seconds and then replace it.
    Note: If the battery light isn't lit, wait a few moments, if it still does not light check your power connections.
  5. Continue charging the battery until the battery light turns solid green once again.
    **REPEAT THIS PROCEDURE 3 TIMES**

If I could be of further assistance, let me know. If this helps or solves the issue, please rate it.
Thanks, Joe
