Re: Lenovo G40 Black Screen in start up after Changing boot mode to legacy

You really only have to unsolder just one of the terminals to break the connection.  Try to de-solder and solder quickly so that the battery doesn't get hot as Lithium batteries can be hazardous to work with. Just so that you are aware.


Once a battery terminal is disconnected, press and hold the laptop's power button for 30 seconds.  This will insure that the motherboard is completely drained and the CMOS cleared.
