My best suggestion for fixing your issue with the disc drive is to remove the disc drive from the laptop. (You can use our repair guide for this disassembly.) Once the disc drive is removed I suggest trying to clean out the inside as maybe something may be dirty or dusty inside. If this doesn't work I may suggest even further repair with buying a whole new disc drive as a part replacement. Hope this helps!
Hi! If your computer turns on but it’s showing anything, here are some steps we you can try to fix it. First make sure your monitoring is working. Is the brightness all the way up? Your computer may still be rebooting. Give it some time then hold down on the power button to allow it to completely shut off then successfully turn on with a visible screen and functioning system. Your computer may very well be dead so, plug the charger in for 1 hour and then come back to see if it will turn on properly with a visible display. Also, because it was left in the extreme cold, it will need to warm up inside before attempting any of these suggested procedures. Good luck!
