Turns on & off every 8 seconds
After a full charge. I am able to use the unit. Then when finished I turn it off but it then starts to power back up with the "apple logo" and then shuts off....eight seconds later powers back up with "apple logo" and continues this process until the battery power is drained.
I have run trouble shooting programs from Apple website, but this does not correct the problem.
Apple suggested I take it to a repair shop.
Anybody have an answer to this?
