Hi Guys!
Here’s what i did. if your kinda tech guy dismantle your ipad 1 then once then on the battery remove the black tape cover of the battery (just the top part of left side battery.. then there will be two terminal (soldered) right terminal is negative right terminal is positive.
Now this is the good part. if you guys have a defective ipad/android charging cable, cut it at the tip to expose the wires and choose of course the positive and the negative one and directly connect it to the battery terminal…
My Ipad is now working again..
Hope it work to all of you.
