Used a Laptop in Europe on a trip, had an adapter and when plugged in a spark occured.? - adapter for laptop europe

Just got off the phone with a friend who traveled to Europe. He had the power adapter and when you connect the laptop, which had a spark.

Well, if you try to restart your computer experiences a blue screen very briefly, and then restart the computer. I do not know how far into the boot process, because his team are illiterate.

What are the possible causes of the problem?
How would I go myself to fix these problems?
