Try to perform power drain first. take out the battery and unplug the power adapter. press and hold the power button for 30 secs. put the battery back in and plug in the power adapter. turn on the computer and monitor if theres is any changes. if same issue happened then you need to replace your battery.

Tip

Laptop Battery Won?t Charge?


If your dell laptop computer runs normally on the AC adapter, but the battery won’t charge, please try the following troubleshooting steps:
Check the dell laptop battery and Connections:
1, Remove the battery from the system.
2, Look at the connectors in the bay and on the battery for signs of physical damage.
3, Check the battery charge by pressing the status button or image on the battery near the LED’s.
Note: The lights indicate the current amount of charge on the battery. If all the LED’s come on when you press the button, the battery is fully charged. If fewer lights are lit, then the battery is partially charged. If any lights flash, or blink, there could be a problem with the battery.
4, Reinsert the battery; push until it locks into place and the latch snaps back to the locked position.
Swap Bays or Try A Second Computer:
1, Some systems can run with the battery in either bay. Try swapping bays if you have one of these systems.
The following systems permit a battery to be used in either bay:
Inspiron systems 3700 3800 7500 4000 4100 4150 8000 8100 8200 Latitude systems CPx H CPt V CPx / CPt C600 C610 C640 C800 C810 C840 Note: It may be necessary to slide the face plate left or right on some batteries when switching bays. 2, If you have access to a second computer like your own, try to charge your battery in that system.
Flash the BIOS:
Flashing the BIOS can correct many hardware issues.
NOTE:Dell recommends that you update the BIOS on your system, only if you are having problems
1, Go to “The Dell support site”
2, Be sure your system is the one listed in the Your System section on the left.
3, Click the Downloads tab
4, Choose your operating system from the drop down menu
5, Select FlashBIOS Updates as the download category.
6, Click Go.
Select the link to download the most current version of the BIOS:
1, Save the program to your desktop.
2, Go to the desktop and double click the icon.
3, You will be given the option to either create a BIOS disk or flash the disk from the hard drive.

Run the Recalibration Utility if Your System has One:
This utility runs the battery all the way down and then recharges it completely. The process takes several hours so it is best to run it overnight. Use only the recalibration program specified for your system. Using any other program could void your warranty!
Latitude LM, Inspiron 3000 and Inspiron 3200 systems use this recalibration program: BATRECAL.EXE
Inspiron 5000, Inspiron 7000, and Inspiron 7500 systems use this program: I75BRCA0.EXE
Latitude LS, Latitude L400, Latitude X200, and Inspiron 2100 enable a recalibration option on the Power page of the BIOS Setup Program:
How to Enable Battery Recalibration
Try to charge a second battery like your own if possible.
If the second battery won’t charge, the problem may be caused by the charging system in your computer.
If the battery still won’t charge after you have done this troubleshooting,it mean you should replace your old battery,you can go to www.sales-battery.com to choice a new dell laptop battery replacement

I purchased a new battery for my Dell Latitude 810 and it still won't hold a charge. The battery indicator light is green for a brief period, turns amber and then shuts off.


If you installed a new battery in your Dell computer and still can't get it to charge, there is a strong possibility that there is something wrong with the charging system

Battery charging LEDs not light but charging up to 76 %


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.

BATTERY WON´T CHARGE ON DELL C600


It is possible the battery where the contacts from the laptop fit into or the gold colored contacts themselves need to be repaired. Worst case, the spill short circuited the contacts on the board, in which case you will have to replace the board. I would suggest really cleaning the gold contacts on the laptop and the small slots on the battery itself with a Q-tip with a little bit of rubbing alcohol on it. Please make sure both areas are totally dry before reassembling the battery.

Good Luck,

Flashing red light


It is an indication that the battery is beginning to fail. Portable system batteries have a useful life of approximately 300 to 500 recharge cycles on average. (Some last longer, some shorter)

If the battery is over a year old, then the warranty on the battery is expired. You'll need to purchase an new battery

Power for battery on DELL laptop Latitude D610 as posted FixYa


In the BIOS, does it show the battery and it's current state? As weird as it sounds, I've fixed an issue like this on a D600 by updating the BIOS to the most current level. Weird, but true.
