Sister-in-law's laptop threw a hissy-fit and will not boot. It turns on, then black screen with a cursor in upper left corner.
Tried recycling power, same result.
Removed battery, recycled power, same result.
Inserted w7 disc, cycled power, got "Press any key to boot from CD or DVD"; pressed key (a lot of them, actually), no response.
Suggestions, solutions, whatever (as long as it doesn't involve weapons, ammunition, or the discharge thereof into the damn machine) ??
Thanks in advance.
