Try a different AC adapter. If your computer doesn't recognize that one either, then you may need a replacement DC-in Board.

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.

I have a Gateway T-6330u notebook. I have had problems with the battery cord before where it plugs into the computer. A piece broke off from the battery cord and was stuck in the computer. I talked with...


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.

My computer won't turn on or charge.


You need to diagnose the problem.
>First try to take the battery out of the computer and just use the charger to make computer run.
>If it turns on it means that the battery is what's causing the problem.
>But, if computer cannot run using the charger/AC Adapter then it means that we have a problem with the charger.
By doing this diagnostics you know which part to replace.

Laptop does want to turn on any more


You'll need to do some diagnostics to really figure out what's wrong.

Find a friend who has a spare battery and a charger and determine by swapping out your battery and charger to see if either is not working.

If you do not have these, take your laptop to the nearest springboard store and ask them to do a quick test of replacing the power adapter and battery, should be free.

If these fail then it would be a setting, the dc jack on your motherboard or the actual motherboard.

Good luck, don't forget to give me good ratings and a vote. Let me know how it goes.

Dell inspiron 1526 has problem (plugged in ,not


Hello there:
First you will want to ensure that the power cord is fully inserted at both the laptop and all the connections for the cord and that it is getting proper power. and check tosee that the connector thatthe power cord goes into is not loose if so this will have to be repaired
next remove the battery from the computer and unplug the power cord and then press in the power button for 1 minute than if this has a reset button on the back use a toothpick or a small item and pressin on the reset button for 30 seconds
now insert the power cord (NOT THE BATTERY YET)
and turn on the computer and it should now start up if so insert the battery and leave charge for 1 hour than you should be ok from here ok
Please keep me posted on this so i can assist you if needed.
Best regards michael
