New laptop for me and sissy

I don't know what happened, but suddenly, laptops here at home went crazy. My sister's and my laptop's chargers got dysfunctional already. You think this has something to do with the power voltage in our place? Or maybe we did something with these chargers? Now my husband said, we should just look for wholesale laptops , maybe we can get it for a good price instead of just buying the chargers.Besides, our laptops needs replacement too. I seriously need my laptop, it is a little piece of me already. My work depends there and I hope I can still open my old one to get my files. Oh well, lesson learned.
