it's amazing. this is me typing on my laptop which has gone past 4 years with me.
the original charger died right during my poly days and in between 2 more substitute charger died on too..
I had no choice but to lend my sis's friend original and when i was overjoyed it was compatible, it died in less than a month ! I was so sad yet pissed yet out of words.
BUT miracle happens ! suddenly, it worked back today and I promise I will cherished my charger .
