Battery Testing
Hello all,
This is my first post so be gentle  I need to test a laptop battery externally, i.e, using a multimeter on the pins of the battery. The probes on the multimeter wont fit in the slots, what do you guys use or recommend to use. Regards, Brad.

Hi Rob,
Thanks for your quick resopnse. Well, the laptop won't start, charging light is on when plugged in to mains and when power button is pushed, nothing happens. If I remove battery and try to turn on laptop while connected to power, nothing again. I thought I could test to see if battery had failed. Brad.

So, based on what you said here, there's no point in testing the battery. The system should run on ac power, with the battery removed. The battery is irrelevant to diagnosing the system's no power issue. Also, as said above, the voltmeter won't tell you anything about the battery's condition. Voltage isn't the only factor that determines the battery's health.

The battery usually won't prevent power on even if its toast.. if the charging light comes on it should be able to turn on with just the charger, no battery. I would suspect the power button is failing in this case. If the power button is on a cable you can short the pins behind the socket the cable plugs in on the motherboard and see if it powers on that way. If its just a button on the board, if it clicks when pressed, its almost always good.
If you really want to test voltage on the battery you can try wrapping paper clips on the probes..
