Question about IBM ThinkPad T23 2647 Notebook

1 Answer

Power fault could it be the power supply?

Has anyone come across this problems before? Currently my T23 ThinkPad has ben intermittently switching between the power supply and battery. One assumes that if I did not have a working battery then the unit would just switch off. It does it repeatedly for a few seconds then works fine on the power for 30 to 40 min. I am worried that this could damage the unit if it continues. If someone could help, I would be grateful.

    This is happening with my computer. I bought a new A/C adapter and it is continuing. Could something be loose "inside" the computer not allowing it to connect consistently?

T23 Thinkpad turns off during boot after restart


My guess would be ;-
A power supply problem with the battery and/or power adapter
The most likely one.
The CPU is overheating and shutting down and if you wait a while and it will power it up again, it will then run for a while and shut down again.
This can be caused by a faulty fan (its not spinning and needs to be replaced) or the vents are clogged with dust (needs to be cleaned and you may need to remove the fan assembly to do this).

Battery/docking station ac power


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.

T23 Thinkpad could not power up


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
