The problems could be in a number of flaws. Firstly could you answer the following questions as best you can?
a
Are these devices purchased in Hong Kong and do they have the 3 prong plug? If not; are you using an adapter/transformer where only 2 prongs are used?
b
What building type are you in? - A very old one or brand new?
c
the laptop, does this electrical surge/shock happen only once or is it repeating?
