I purchased my blackbook in late Sept of last year. Now I am havin sleep issues. The laptop will simply fall asleep during use. Right in the middle of typing it will go to sleep. It requires several presses of the power button to come back on. I have adjusted the power settings in several different ways. The battery reads full. I ever charged it overnight to make sure it was fully charged. All of the capacity lights light up. I have shut it down several times and restarted to no avail. Anyone have any thoughts? Thanks in advance.
