Hi @cmackinnon, you may take one of a few solutions to fixing your problem. First check to see if your battery is fully locking into the charger, if it is then you may have a dead battery. Check to see if your back-up battery is charging by placing it on the charger. If the back up battery is not working you most likely have a broken charger. Check out the DeWalt DW920 Troubleshooting page here if you have anymore questions. DeWalt DW920 Troubleshooting

Hi @cmackinnon, if your drill won't change direction you most likely have a problem with your rotational switch. It may be broken or disconnected from the switch on the motor that changes the drill's direction. If you check out the rotational switch guide here it should tell you how to fix it. Good Luck!
