N/B: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. Am really confused and worried over this new development in regards to my Apple laptop,because l cannot use this rented laptop for my work in the site here,as it's gonna affect my work here ie my building drawings,layout,even my prompt and effective communication with you and am unable to get a new Apple laptop overhere,due to the fact that here is a third world country and am unable to use my credit card here.
