My problem is that when I connect the original charger to my laptop, it charges for 5 seconds and then disconnects. Sometimes this error occurs, sometimes it doesn’t. It usually happens at my workplace office. What could it be? My laptop is an Acer Aspire 5.

I’ve already tried completely draining the battery and then recharging it, but it seems to only work with the power outlet at my house. Although, once I did encounter the same error even at my house.
