recently dropped laptop while going up stairs and can't figure out this error.
Acer Aspire m5-583P
System BIOS Version: V2.22
VGA BIOS Version: Intel V2171
thank you for taking the time to read this.
It is saying it can't connect to your drive. It is possible it just got knocked loose, the connection inside, and opening it up and reconnecting it will resolve the problem. However, if that doesn't do it, then it is also possible the drive was damaged and will need replacing.
If the laptop is under warranty, then I would contact the manufacturer about a repair. If it isn't under warranty, then either you can try doing the work yourself, or take it to a local tech.
