The most common problem I am getting with Laptops is the power does not work

This IS DEFINATELY from wiggling or bumping the power plug while still in the laptop

UNDER NO CIRCUMSTANCES should the power plug be moved side to side or up & down

If you have to ....twist it (a little) to remove it

This can sometimes be repaired but it is a BIG job (a Couple of hours)

OR the motherboard will need replacement.

Built in life expectancy is still about 3 years for a decent product

18 months for a cheapy
