I bought my mom, who lives in India, a Panasonic toughbook CF-W8 a couple of years back. A few days back, due to some voltage fluctuations, her adapter/power cord blew out (along with a whole bunch or other stuff in the house). Her laptop is fine and she has used it a bit with whatever power it has remaining. I have bought a new adapter for her over ebay and it should reach her in 3-4 weeks. In the mean time my dad asked a friend of a friend to fix the adapter and now some random person has "fixed" the adapter.
Now I am a bit nervous about the state of the adaptor and have asked my mom not to use it since i don't want her to damage her laptop.
I was wondering if there is any way to test if the "fixed" adapter is safe for use? and also, I just want to confirm that it is indeed dangerous to actually try the adapter on the laptop since I have no idea if the person who fixed it knew what he was doing.
