    Lenovo X61 (Tablet-Pc) How to charge the battery manually?
  • Questioner

    it seems that my new battery of my lenovo x61 notbook got "deep discharged" due to a 4 month period of not using the notebook at all.

    It seems that the "electronic" inside the battery does no longer allow the battery to be recharged if it was once "deep discharged". So the computer shows me "battery not recognized, please buy a new one/replace....". However the battery is more or less new.

    Does anyone of you know where I can get information how the pin-assignment on the battery is, so I can charge the notebook battery "manually" until the eletronic starts working again. Or where to get this information.

    I was not able to find any information about this at all.

    Thank you very very much! jan

    Recharging a deep discharged is dangerous which is why the batteries electronics stop the computer from charging it. Attempts to recharge from a true 0V lithium battery pack can cause the cells to fail violently when charged.

    The battery cutoff is a safety mechanism in the battery. If you do attempt to recharge it could be very dangerous (Fire, Smoke, ect...) but if you want to most batteries have tiny text to show which pin is the +, -, T for communications. Charging should be done as slowly as possible with a lithium battery charge controller. Depending on the design of the batteries safety circuit it may be required to disassemble the battery to access the cells directly to bypass the cutoff.
