IBM T23 Thinkpad battery does not charge

I noticed you responded to a battery question on Fixya. I have an IBM T23 Thinkpad where my battery went down in power percentage when running on battery, but when I plugged it in to charge back up, the battery indicator goes to green (like the battery is charged up) but when I turn power on to check battery status, it never increases in any battery power percentage. I know the external charger itself is working because it supports running the machine just fine..... it is just the battery charging that just stopped functioning.... almost like there is a blown fuse going to the battery from the charger. You mentioned to change the bios battery in your response to another person's question. Do you feel this is the case here? If so, could you give a brief description as to why? Would the bios battery actually halt the main battery charging for some reason?

    I have the same problem. Can anyone help?

  • Norm Roller Nov 26, 2008

    Since 11/14, (when I wrote my original note on this), I have done more investigation and testing. So now, I can answer my own question here and maybe help some others with a similar problem.


    To make sure that I had a known good battery, I ordered a new battery. I found that the system would not charge the new battery either. To verify the new battery was good, I even put the new battery into a friend's T23 and it charged up to 100% just fine there. I then put the new charged up battery in my T23 and it ran the system fine and discharged fine while running the system, but when I attempted to recharge this new battery in my system, it would not recharge. The ac adapter would just maintain the level it discharged to but would not recharge it. Just to verify that the battery recharged fine, I again put the new battery in my friend's T23 and it would recharge there back up to 100% just fine. End result of this testing is that I have a good battery that will not charge in my system.

    AC Adapter

    To verify that it was not the ac adapter, I put my new battery that was discharged down to around 80% into my T23, and plugged in my friend's charger, it did not do any charging. I also clicked on the battery % icon on the bottom task bar and brought up the Battery Information window. The battery information window showed a normal amount of battery discharge for both current and wattage when the ac adapter was not plugged in, but when the ac adapter was plugged in and it was put into the charging mode , there were no bars for current or wattage. The only thing that showed any reading was the voltage bar that was around 12v. To give it one more test, my friend also had a 2nd IBM portable ac/dc combo adapter. So tried that one too with the same results as above. So...... 2 known good ac adapters that charge batteries just fine in my friends Thinkpad does not charge a known good battery in my machine. End result of this testing is that the ac adapter is not the problem.


    I have a problem with the charge/recharge circuits in my T23 Thinkpad. Unfortunately, I am told fixing this problem involves replacing the motherboard.

    Same issue. Charge current zero, voltage indicates about 12.3V. Battery tests fine in different T23 and T22.

    same problem exactly

    I have a very similar problem in Lenovo X60. Status shows as "Plugged in and Not Charging". Wondering if there's a fix somewhere.

  • Norm Roller Dec 18, 2008

    Thanks for your input, but I have resolved the situation as I described in my note above. It ended up being a bad motherboard where the recharge circuits were blown out. Thanks.

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.

I think you have a battery problem and that is why it is not charging properly. Its need to be recllibrated. Try this

Run your laptop of the battery until the whole battery power comes to zero. When it does the laptop will shut down automatically. Now connect the charger and try to recharge the battery. Don't turn on the laptop, just switch on the charger.

Wait for about two hours, and start your laptop. If you see the same thing as before, then you might need to change the battery.

Power-on password problem!

The power on password is stored on an EEPROM chip and removing the BIOS/CMOS battery won't help.
You need to read the EEPROM chip to get the password.
for solution to your problem (you need to construct an interface hardware and install two programs on a working computer)
