    Batteries won't charge. There are two batteries are working fine. Stopped charging before, but begin charging again when I purchased a new power chord. But now going back to same problem.

  • joshs71 May 04, 2010

    This troubleshooting still doesn't work. If there is a problem with the charging system, is there anything I can do or do I have to take it to a repair shop?

If your computer runs normally on the AC adapter, but the battery won't charge, please try the following troubleshooting steps:

  1. Check the 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.

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.
D. Consult the Tell Me How guide for more information on battery LED's:
E. Where to find the Dell Tell Me How and User's Guides
    1. Reinsert the battery; push until it locks into place and the latch snaps back to the locked position.
  1. Swap Bays or Try A Second Computer:
    • Some systems can run with the battery in either bay. Try swapping bays if you have one of these systems.
    • If you have access to a second computer like your own, try to charge your battery in that system.
  1. Flash the BIOS:
  2. Flashing the BIOS can correct many hardware issues.
  3. 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.
  1. If the battery still won't charge after you have done this troubleshooting, please [Reply] to this message and be sure to include the following information:

First check and see how old is the laptop and battery.
If the battery is old enough to be replaced then without delaying you must replace the batteries.

If the Laptop is not older than a year then you must open the batteries and check if there is any physical damage or not. Especially leaking problem.

At the bottom of it you will find 2-4 screws to remove where the battery is fit.

Those are the only check points for batteries.

    The only problem that i see here is DEAD BATTERY. The battery that you are trying to charge must have died.

    Bingo, that is what i meant to say. Except for repair shop (purchase Battery) it will not go ahead.

Pc booting light blinking battery

As a rule this indicates a low battery or a failing battery. If you charge it and it drains quickly, it needs replacement. When getting a new battery (power cells), fully charge it overnight and use it until it drains completely. Once it is recharged for 24 hours, the batter will obtain a memory and last longer.

    Battery light flashs orange continusly on a dell latitude d620 if i disconnect the power cord the computer shuts down

    Two possible causes for flashing Amber battery light.
    1) Your battery won't charge and needs to be replaced.
    2) Your charging circuit for the battery is defective and then your motherboard of laptop will need to be replaced.

    Dell latitude d620 power on password can't remove

    No need to short out any pins, shorting out pins allow you to reset the BIOS quickly. When you leave the BIOS/CMOS battery out overnight, this will reset the BIOS (you only need to leave the battery out for 1/2 + hour to do the same thing).

    Is any cheap battery for laptop d620

    Hi - i've ran a D620 now running a D630 and yes the battery life is extremely poor even when the battery is new.
    The option above will give you extra - you can also buy a moduler battery that will fit into the CDROM port which will give you even more!

    or ebay is your best bet...
