Keyboard and touchpad oddly responding - 2010 MacBook Air 11

Baterys are the bane of devices. When they go or get replaced its curtens for the device. I know of now of 13 cases were the batery was a problem. first off the batery is junk new or not. Second your device is damaged. Third its cheeper to replace the whole device than parts unless you have this exact device in your bone yard and even still its a lot of work to frankenstine a new. Forth if you frankenstine a new you will void warentys if there be any. Fifth if you dont have it in your bone yard parts are so expensive vs a new replacement. Id send it to the great device in the sky and add its corps to my bone yard. Then again there may be hope, the device was "fine" before Am***n's batery, so under the baterys warenty you stand a slim chance of geting the device fixed as it was the batery that damageged your device. Bone yard or batery warenty repare its your choice. I hope this helps.
