HP dv9410us Vista
When my notebook goes into sleep mode, the display will not come back on. I power off and then when I power back on, the notebook will start to boot then shuts down & reboots. I have to push the power button several times before it will finally boot up. Once it is on it works fine.
Any suggestions on how to fix?
