My IBM Thinkpad T30 does not power up. With AC adapter only unit shows no power, with AC adapter and battery together unit gives a green light for a few seconds and then battery light goes orange and stays orange. Power supply gets hot and battery is warm, my thought is the adapter may be bad can anyone offer a solution?

Thefollowing three conditions should be met for you to use a charger safely.
1)Output Voltage is within +/- 5% of your old charger's output. For example, ifyour old charger provides 19.5V, then you can use a charger that provides 20.5Vor 18.5V. 2) Output Current is the same or higher than that of your old charger. For example, ifyour original adapter provides 3.42 Amps, then you can use a charger thatprovides 3.42 Amps, 3.9 Amps or higher. 3) Connector tip must fit securely into your laptop.Pleasecheck carefully before using nx9110 adapter on t30.
Remove all power sources(battery and AC adapter) from the laptop. With the power source out, press and hold down the power button for 15 seconds. Then, power on the laptop using the AC adapter only. If this does not work, issue might have something to do with the motherboard.
Sounds like you are losing your backlight inverter. It sits under the bottom of the screen and is responsible for converting the DC power of the battery and power adapter to high voltage AC for the backlight in the lcd panel.
There could e a problem with the battery. A fast check to determine whether you have a problem with the power
adapter, power cord or the laptop's battery is to turn off the laptop,
remove the battery, connect the power adapter, turn on the laptop &
see if it works. If the laptop works directly from the power adapter
with the battery removed, then the power adapter is good. In this case
we can suspect that the battery is defective & needs to be replaced.
Try also to reseat the main components of the notebook: the battery, the AC adapter, the memory modules, & the hard drive. After that try switching it on & see if the problem was fixed.
If prior to this it works intermittently with the AC adapter, it means the connection from the adapter power unit to the motherboard was lost and this is a typical problem with the Thinkpad. It needs a re-soldering job and not something that one can do without a proper repair manual on how to open the laptop. Try googling your problem and find out if someone has the same experience and managed to resolder by him/herself.
You might try cleaning the battery compartment. Makeing sure there are no damaged pins. Often times even a single messed up pin will cause this. Also this is a very good indication of adaptor failure. If you haven't allready I suggest getting another ac adapter specific to you machine. Even a substitute will casue the same issue you are now experianceing.
