    My Think Pad 42 Laptop cannot run on AC. Its battery is weak and if it is fully charged, it runs out for only 15 min. If I plug in AC and with fully charged battery, the computer can run for 30 min. What is problem with my computer?

    Check the converter with a multimeter tester make sure it is puting out the correct voltage. If it is then your battery is probly faulty in need of replacement.

    Thx Mointain.
    I know that the battery needs to be changed but why if I remove the battery and use only AC, the comp. does run?

    I take the battery out of my HP lap top and run ac only and it works fine; that is just the way it works. from what I understand you to say, that if you do the same it runs fine. But, if you add the battery (charged) and run it pluged in, it runs for 30 min and around 15 min unpluged and on a weak battery. Mabe the converter isn't putting out the proper voltage to charge and run the system. Furthermore, you still show signs of a worn out battery. Check the converter with a multimeter tester.

    Hi Mountain,

    Sorry, I should say " If I remove the battery and use only AC, the computer DOESN´T run" or more precisely runs for only 1 min.

    Test the converter with a multimeter tester. Sounds like you need to change the battery and the converter, it happens; wear and tear. Good Luck.
