T23 IBM will not operate on battery power & won't charge battery.

poor battery contacts or dead battery cell doing this flickering


replace the battery if contacts are clean inside the computer

Try ejecting it and putting it into the other multibay to see if it works. What sort of symptoms is it exhibiting? It is probably dead as this is an old system and parts wear out over time, especially dvd-rom drives. These are pretty cheap and can be replaced easily. Make sure you save the dvd rom frame and ide connector from the drive as you will need this to apply to another drive.

I would return the drive if you bought it on ebay for a functioning one. Most reputable sellers will test items before shipment and refuse shipment if it fails testing. Other fail safes are having a period of time to test the item and return it if defective.

Go to the IBM/Lenovo WEB site - support/download page and download the latest Windows XP audio driver for your model laptop,

It doesn't look to me that you're doing anything wrong there.
Was there a specific installation requirement for the battery?

I recently changed my battery on my IBM/Lenovo and all that was necessary, was to let it charge fully before usage.

If you say your battery was charged for "a few days", then I assume there is something wrong with the battery. Next to your taskbar you should see a battery symbol. Double-click on it and you should see the Thinkpad Power Manager. If there is a tab called "Battery Information", see if that gives you more details. Look at the Manufacturing date!

If you really can't run the laptop without being connected to a power source, I would definitely return the battery or at least call the vendor. If your computer is running fine otherwise, there should be nothing wrong with the machine itself.

If you can take a screenshot of that battery information window adn post it here, I am happy to look at it.

PS:
You're doing the right things when you try to use the laptop without an external power source - that's the whole idea, isn't it?

Do you get steady or blinking CHARGE indicator light on the laptop somewhere? If not, the WALL-Wart/External power supply or its connection is bad. This can be due to stressed wiring, bent DC socket or cold-solder joint where it mounts to the motherboard (inside case)... or bad outlet (house socket) or a blown PS

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

This is a commin IBM issue fans going Bad ... to try and free it if it's just dust you can actually blow into the vent with compressed air and free up the Fan ... The IBM T series all check fan before powering up.
The replacement is not too difficult to do.
The safest air is the can type to blow in there.

Good Luck

it sounds like a component within the laptop may have failed, that controls the battery charging ,but allows it to run the laptop when plugged in.

unfortunately its not something that can be fixed via text messages, you need to take it to a pc shop to be fixed.

good luck with that

then the battery is not holding charge try leaving power cable in and switch on
