I might be asking a stupid question but did you be sure to:
1. unplug your power cord from your PSU?
2. Press the power button on your tower to discharge any excess power?
3. Take out the actual battery and not mess with jumpers? I have a DS3 965p and all I had to do was take out the battery. I left mine out for about 5 minutes. I never touched a jumper.
