The chip that controls the charging circuit of the battery has to be replaced--defective-- it is a 8 pin surace mount-- the only number on the chip is 4805---believe it to be a mosfet--need the original part number or the specs

If the D610 works when attached to the AC Power Cord, it is likely that your battery is not capable of taking a charge and needs to be replaced. I have 2 D610 Dell Latitudes and they are very good laptops. Please vote if my information is helpful or not. Recommend me. Thanks UAW 974
If you are still encountering the problem charging your laptop's battery, it is possible that the port where you connect the adapter or the port for the battery is damaged. It will still receive power but it won't charge.
Best solution is to replace the motherboard. Just make sure you would get the exact same devices on a replacement board.
This is possibly an internal power Supply fault. take the battery out, plug in the adapter, IF the unit works now, you have A: A battery problem, or B: a charging circuit problem. If the unit still fails to work, the power supply in the PC has faulted. You need to get a "Quote: for a repair.
the charging system on your motherboard has blown a capacitor, if it is still under warenty you should call 1-800-456-3355. to get it repaired. if it's out of warenty, they can help you buy the right part
What needs to be done is the jack that your adaptor plugs into has solder points underneath it. All the solder points need to be resoldered to make sure that there are no cracks in the solder that are preventing the jack from charging your battery.
After this is done if the laptop still isn't charging then if you know for sure your using the correct ac adaptor with your laptop then at that point the moterboard would have to be replaced.
The battery light flashing RED/AMber is an indication of a failed battery.
Portable batteries have a life expectancy of 300 to 500 recharge/discharge cycles. (roughly 18 months under normal use) After that, the charge life starts to drop off and eventually it will not hold a charge. Because of this, the battery is considered a consumable item and is only warranted for one year from the manufacturer.
Since all the systems listed in the post are D610's (4 to 5 years old) it is not surprising that the batteries are failing.
Dropped Puck, if you replace the battery and a new battery doesn't charge/run the system, then the charging circuit on the MB is failed.
First off, do you have a way to check the output of the ac adapter to ensure it's putting out the correct current?
If you've done that and have a multimeter handy, you can remove the battery, system off, and check the charge pins for current/voltage. I believe one of the end pins is neg (ground) and at least one of the other pins should show 2.6-3.6V, as well as other various voltages. If you fail to get any response at the charger pins, we'll need to look at the board circuitry, assuming again that the ac adapter is operating properly.
I had the same problem on D610, it was not charging the battery and also the CPU speed was showing only the minimum 800Mhz though maximum was 2Ghz. I updated the bios (though it had the newest version) and ran intel chipset driver for D610. Viola! it set the speed to 2Ghz and the battery started charging. Was it a miracle or a solution I dont know!!!
