Power problem i have a ibm thinkpad t23 that runs linuxos and when i press the power button nothing happens. i tried charging it and now the battery light flashes. what is wrong

poor battery contacts or dead battery cell doing this flickering


replace the battery if contacts are clean inside the computer

Try to perform power drain first. Please follow procedure below.

Take out the battery
Unplugged the power adapter
Press and hold the power button for 30secs
Put the battery back in
Plugged in the power adapter
Turn ON the computer

If same issue will happen after this troubleshooting. I suggest you purchase a new battery. If you unit is still under warranty, you may call IBM tech support for battery replacement.

try to switch it on with power cord still plug in it, if it do boot-up, you have to replace your baterry, if not somethings wrong with your 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 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

Have you tried to power on with the ac power connected.

I would check the power adapter with a multimeter first thing.

Your machine should run without the battery, just plug it into the power supply. You may check the powersupply itself. Maybe the power supply was bad and not the original battery. You can pickup one at a computer store. A universal costs around $100.00 to $120.00. The power supply is the (usually) the rectangle box that is part of the power cord. Let me know if that was it. Good Luck. Tim
