I have a Dell Inspiron n5110h laptop which started having wifi connectivity issues a while back. So I went to a local market here in Jaipur ( RAISAR PLAZA) which is notorious for cheap repair of laptops and many a times improvised defects in laptops as well. So I somehow got my wifi issues resolved. But now l've started getting autorestart issue in the laptop which has never happened before. So assuming that it was induced by the repair person in the market, what could have he done in the laptop( like tempering the power supply or other hardware) which has caused this problem??
