Mr G is a person who will worship the learned and throw them off in
the mud; he will not weigh the contents, but will believe that person who
according to him so qualified, writes only the truth; he has no source of
verification but believes all things truth; at the same time, he will also
write Q & A is not reliable and will contain all errors; and he will
worship stupids and cock bull shouters, will criticise English writing
having a lot of errors in his write up; he is a flying leaf ,sailing
across, ,always have the highest confidence without knowing he is not
tribe; He and his false guru will write in Malayalam that too shit, and he
will comment "shall not others read ? Why do you write in Tamil?; there are
several language speakers heer; why don't you 2 follow your own
scriptures?. I do not have any grudge against anyone; they do have; if they
think their abuse is correct I retort and they have to bear; The bundle of

Q2 {Before this what about q 1 like ,raising as if a media headline and
then answering against it?Why such insipidity. } The expert according to
the copy and paste master (who will say only others are doing!!) is that
people keep 2 laptops because there are no spare parts-revealing the
ignorance. All Laptops on and after 2010 , is repairable as revenue and
capital investment, by repair and updation, through the chips. Before 2010
also is not a problem; but those were GLUED; thereafter no more gluing but
simple dot applications; while the prior 2010 might get damaged while
removing, 2010 + are simply removals as it is without any damages,
replaceable, and the removed part is also reusable. 2010 can be made 2022 .
I have about 15 cell phones and 5 laptops , which is in working conditions;
but because I bought a new model they are with me; they are with me
because, the electric goods might be misused if sold as the recovery
hackers are too many; and in India (unlike USA where the destruction is
demonstrated in front of you} destruction might be bogus. So I hold all of
them. There are so many companies ready to update. (PC Magazine reports}
