My laptop developed a terrible problem here,as i have contacted a hardware Engr. who checked it and confirmed a crackdown of some multiple internet boosting chips and other damages and recommended a replacement, l never knew that overhere in West Africa(Nigeria) their light voltage is higher(240 volts)instead of the US light Voltage(210 volts)but i was able rent a poor laptop(1 GB RAM - 60 GB disk),which i can only use to communicate with you for few days,not for my work in the site,because my former Apple laptop(Solid State Drive - 15.6 inch - 8 GB RAM - 500 GB disk - Intel CPU - 1.9 GHz CPU - Intel GPU - 1920 x 1080 - 5 pound - 3.8 hour battery) which l use to work as l just told you earlier developed a terrible problem overhere,due to high light voltage.
