RE: System or hard drive crashed ?
There no 4510 model in Dell Inspiron line.. Can you provide the exact model number? eg: Inspiron 14R - 4010..
If the battery is removable.. remove the adapter, remove the battery.. press and hold the power button for 2 minutes.. then put the battery and connect the adapter and try booting again..
If you get the same problem again.. suggest you to contact Dell support keep your service tag handy when you call them.
