Hello,
I bought a new laptop battery as the original one was oly lasting about 4o mins, with the adaptor plugged and the new battery in, the battery icon says its at 55% and charging but as soon as I take the adaptor out the laptop looses power
Is it an official battery or 3rd party. Sounds faulty to me.
We sometimes sell IBM batts at my shop and have to change them for different models just to get them to work even though they are the same as the one we replaced.
