this sounds similar to issues I was having when I got my A4 -- eventually this issue was fixed with a software update. Thanks for the Tip on this one. Hopefully it will be worked out when I finally decide to purchase an A4+
I have reported all my found issues to "miner_support@innosilicon.com.cn" and I suggest everyone with Innosilicon stuff do the same. No matter how small the issue may seem.
Report them all...
