Question about IBM ThinkPad T23 Notebook
I use a docking station, but somehow I'm currently just working off the battery. How do I change back?Sue
There is no manual way to switch from battery to AC, the machine or docking station should automatically switch between battery and AC. There is a power management chip inside the laptop that regulates the power and switches from battery to AC when plugged in. Some docking stations have a chip built into them to do this. Start by ruling out the power supply. Do this by undocking the laptop and plug it in using the power supply that is attached to the docking station and see if the machine is just running off of battery. If it is running off battery, then check the power supply with an ohm meter for the proper output. The output readings are on the supply. If you have two power supplies, and you know one works with the machine, try that supply on the docking station. If the power supply checks good, then I'm afraid the pm chip on the motherboard has gone out. You will need to take this in to have it professionally diagnosed, because it could be a replaceable component that works in conjunction with the pm chip. However, if it is the pm chip, then the motherboard will have to be replaced in order to fix it.
