    Assuming you have a laptop and not a Desktop: Check if there is a small pinhole in the back of your laptop (with a battery sign) and stick a pin in that hole till you feel it click (micro switch), keep pressing the pin for a few seconds. This will reset the battery.

    Power drain + CMOS reset: Open the back of the laptop and disconnect the battery cable from the motherboard. Locate the CMOS module (with 2 twisted wires Red and Black) and remove the coin battery. Shorten the +/- contacts inside the CMOS capsule for 2 seconds and put the coin battery back with the + sign facing up, close the CMOS capsule. Next, press the Power Button on the keyboard for 10-15 seconds after that reconnect the battery cable to the motherboard. Close the laptop, plug-in the adapter and try to boot.
