The dvd/cd drive opens up randomly. I've had this laptop (L775-S7114) for 3 months. I called tech support they say it is a software issue and would not be covered under warranty. Does anyone know why it opens up and how to fix it?
Try using it in Safe Mode to see if it happens there. If it does, continue with a clean boot to troubleshoot the cause. If it doesn't, you may want to try a factory recovery.
Recovering your laptop to its original, out-of-the-box state is a great way to eliminate software as a possible cause of the problem. Note that doing a system recovery will return the laptop to its default conditions, completely wiping your data. Information on how to perform a system recovery can be found in your user's guide. On most models, holding '0' (zero) while booting the computer will s tart the recovery procedure.
If it persists after a recovery, you should contact customer support again and let them know that a recovery didn't fix it.
