Always worth trying this as it is quick to do. It has been know at odd times to get a computer out of a loop:
Turn off laptop and disconnect from power. Remove laptop main battery. Hold the Power Off/On button in for at least 20 seconds to discharge the motherboard components. Re-assemble and see if it helps.
Always pop back and let us know the outcome - thanks
