IBM T 42 - Not starting

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...

    Hello, I have the same problem with R50e. Did you find any solution Please?

  • henrik-fixya Sep 14, 2008

    Same problem here with an R50e. I asked my boss if I could take it home. He said yes and I took it home. To my surprise the machine booted and worked for almost two days (with several reboots due to windows updates, benchmark tests, and burn in tests that stress the CPU and memory.) Now the Problem is back.
    I guess It has to do with large SMD components on the motherboard that become lose when the motherboard flexes. A known problem

    The only thing that starts up are the LEDs and the CPU fan.
    I think they are (left to right)
    NUM CAPS HDD POWER BATTERY SLEEP.


    • When pressing the power button all LEDs light up. (except for the wlan indicator which is a bit separate)

    • After about a second BATTERY and SLEEP will go dark.

    • After a little more than a second BATTERY comes back. (If I pull the
      battery and only work with the AC adaptor the BATTERY LED will stay
      dark after the initial stage)

    • Half a second later NUM and CAPS go out.


    • HDD POWER and BATTERY (if a battery is presend) will stay lit.

    You can hear the fan spin up quite a bit so I guess the CPU is running at full speed.

    Notes:
    The ThinkLight does not work. Usually It does as soon as the BIOS is done with the POST (power on self test).

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.

IBM ThinkPad T30 2366 not start without battery


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.

When i turn the laptop on it just beeps several times and the battery and the circle with a Z looking thing light up.


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).

Please rate this solution to keep the good answers comming!

Good luck with your tabled PC !

Try doing a hard reboot.

Unplug AC and remove battery.
Press and hold POWER for 30 seconds.
Plug in AC.
Turn on.
Upon bootup insert battery.

If this does not work I regret to say the graphics card is busted.
