  • If you have a laptop/notebook/netbook/ultra book, & it has a removable battery, remove it & try pressing the power button without battery & charger plugged in, for a few seconds (10-15 seconds). Release the power button, plug the battery in and check.
  • Another thing you can try is that you can Press DEL/F2/F10 to go into BIOS at the time of system start up & locate the option called ACPI mode/version & set it to the highest value. (example : ACPI 2.0 or ACPI 3.0)
