On most toughbooks please follow these instructions in order: Step 1: Please Un-Plug AC Adapter (External Power Supply). Step 2: Please Remove Internal Toughbook Battery Pack (In some cases, you must release the latch located on the underside of the Toughbook). Step 3: Do not put back the internal battery but plug back in the AC Adapter. Step 4: Turn on the power (ie. start-up the Toughbook with the power button). (In most cases the Toughbook will turn back on without the internal battery pack). Step 5: Once the Toughbook is powered back on, do a complete shutdown of Windows. Step 6: Put back the internal battery pack. That is it. Your Toughbook should now work as normal.
