I am not able to start the laptop.
When I switch it on, the lights come on and in a second two lights - battery indicator and the one next to it - stay on...others go off. The laptop does not get booted. Nothing comes on screen.
Have checked the Power Cable, battery. both are fine.
What should I do?
To me it appears it fails after doing keyboard test...

Re: IBM T 42 - Not starting
If the laptop is not even getting to boot the hard drive, then their may be a problem some where on the motherboard and it may need to be replaced.
Before replacing the motherboard, there are a few things you can try.
1) If you have extra memory, try swapping in new memory and see if the laptop boots then.
2) Try disconnecting all peripherals and add-ons and see if the laptop boots then.

Try to start the laptop without battery (remove the battery and plugh the adapter and switch on) if problem persists. Take it to the Service center , Becose your laptop motherboard may have some kinda SHORTS. best of luck
It is NOT Battery or Power Supply it is your laptop itself has gone faulty... You need to troubleshoot the Motherboard, hard Drive etc, to find the exact problem that will allow you laptop to start. A laptop, will go, with just the power supply, and NO battery, if it doesn't either Power Supply is faulty, regardless of lights, OR the laptop's motherboard or hard drive is faulty, you must isolate problem.
Ok, the tilted-Z-in-a-circle represents the power indicator. As far as I know the power indicator is orange while the battery level is below 60% and charging, and green above 60% and charging. When the batery level is above 90% the power indicator starts blinking (green blinking) to let you know that the battery is almost fully charged.
Please try to turn on the laptop without the battery attached and secondly without the power cable attached. Does the laptop still beeps?
If yes, this could indicate a failure of the battery / charger / mainboard charging bridge.
First, if the battery starts to fail, you should be able to start the laptop by removing the battery. If this helps then you have to buy a replacement one.
Second, check the power the charger outputs (by using a voltmeter) and compare the voltmeter reading with the power adapter specifications (read the sticker on the power adapter). If there is a difference of more than 1-2 volts then it means that the power adapter is toasted. Buy a new one and everything should be ok.
Third - if the mainboard charging bridge has problems - this can only be investigated by a laptop service specialist. It can be fixed either by replacing a passive part or by replacing the motherboard.
The beeps you hear can be a code by which the laptop tries to tell what the problem is.Please describe the beeps and the timeout between them(e.g.: beeeeeep-------------bep---bep---bep -- this is the signal that the VGA adapter is no longer recognized).
