IBM T22 Battery won't charge & is not detected

My T22 will not charge the battery or even recognize that it has a battery (power mizer says battery is unknown). Have replaced the battery and the motherboard & tried 2 power supplies. The battery indicator led flashes yellow indicating a discharged battery. Any ideas?

Take it to a very good technician who will open it up and check a dry joint in the charging system.  Sometimes if you donot attend to it quickly you may find your T22 refusing to power at all with the AC Adaptor.  Delicate soldering may solve your problem.  Power may not be getting to the charging circuit and the battery thus it is totaly discharged.

Remove the battery and try to power on without it. Replace the battery if the computer powers on. If not, the motherboard have to be repaired/replaced.

IBM T22 laptop can't get it to start and not battery or charger.

What may have happened is that your power supply may have malfunctioned. I would try to plug another cable (new and functional) just to deny that this is the problem.

Can't power up. my IBM ThinkPad T22. I have the green light that indicates that it's charged up, however when I push the power button it just makes a flash and nothing happens.

If you only get a green light, try removing the battery first. If a laptop battery has gone bad, it will prevent a laptop from booting up.

Now, if removing the battery doesn't resolve your problem, check the laptop charger to make sure that the adapter has not malfunctioned.

If your fans are spinning, then the problem is probably the one listed below.

The transformer may not be converting the voltages properly.

Try these steps first. If it comes down to the internal transformer, then you have to contact IBM.

My IBM Thinkpad T22's battery doesnt last. can i fix that?

Basically you need a new battery. Recharageable batteries have a finite number of charge and discharge cycles and they lose their full charge capacity as the get older. The batteries will have less capacity over time ie less available battery time, and when it is worn out, it won't charge at all.

Getting hot underneth

Both batteries could be dead. But if you bought a new battery, it's unlikely. I don't know what green light you see, but if it's on the power adapter, it just means it's turned on--not that it is charging.
Two possibilities: Your power adapter is bad or the motherboard is bad. Because you say the computer works if plugged in, then you have ruled out the adapter.
You should be checking/cleaning the battery contacts and if all else fails, going for a new motherboard.

IBM Think Pad T22 auto -shut down a few minutes

Try running it without the battery. Sometimes an IBM battery can develop a short and cause this. If it still does it without the battery, I'm afraid it's the power management chip on the motherboard, and the motherboard will need to be replaced.

My T22 unable to start

Hi Yamato,

It is possible that the battery has been so depleted that it gobbles up all the power from the charger/adapter and leaves nothing for the laptop to use. Perhaps what you can do are:
1. try and charge the battery at least overnight with the laptop off;
2. use the adapter/charger only and remove the battery from the laptop.

Hope this be of help. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Battery/Power Issue

Cant help with the "cheap bastard" part, that is for your own edifcation. Anyway, have you adjusted your laptop power/battery settings. If you have tried changing your settings to "Max Battery", and it is still doing this it is probably a hardware issue between the MB and the battery interface. Thus the second part of your message might be comming true. Sorry.
