WILL NOT CHARGE BATTERY

If you can reach inside the computer and rub the battery contacts gently to remove the corrosion ,which is invisible , this will help greatly. Sometimes even a new battery will suffer the same. Clean the battery contacts also turn off the laptop and charge it fully do this on a regular basis. Say once every 2 months

it could be a couple things: Are you using the standard 90 Watt ac adapter, or the Travel auto/Air adapter. The travel adapter is only 65 watts can will charge the battery
If using the standard ac adapter, see if you can try another Dell D series adapter and see if you get the same error.
If same with another adapter, the issue is the charging circuit. If another adapter works, then replace the adapter.
If the charging circuit is bad, it will be the chargerboard or if intergrated, the motherboard

Either battery or charger is faulty.

Dell systems will not charge the battery without a Dell Branded AC adapter connected to the system (The BIOS looks for the adapter ID and disables the battery charger if not ID'd)
It appears, that since the system will not power on with either AC adapter, that there is a problem with the power connection of the system. You can replace the power board

if that fails to resolve next is the motherboard

Get a 90w adapter is the only resolution. The D810 on a 65w adapter will:

1. Disable the battery charger
2. Run slower due to throttling

The 65w adapter MAY charge the battery if the computer is not running (Not sure on that)

The battery has likely been charged one too many times and will no longer hold a charge. Buy a new battery.

do you have a hard drive install??
laptop need a hard drive to start up. the one time start up you see before is just a accident.
as far as battery not charge, that is the porblem you run into, when you get laptop from ebay (taking chance).
you also need to download all of the drivers from IBM for the laptop.

If you have some electronic skills and are not afraid to open up your laptop then I might have a solution for this. It could be a known problem in T23 where one component is loosen from the mainboard and in that case it can be fixed with a soldering iron. Other possible cause is blown fuses. But to confirm this you have to remove the keyboard and do the check.

in the case of my T23 laptop. when i plug in the ac adapter the battery will charge but when i turn on the power button. It won't boot and will shut off eventually. cant you help me with this

hello,by anoteher charger,you`r capacitor on charger is poor.best solution for you is to by a new charger,that is 100
