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
A Note for I Phones and Mobile Phones
Past experience is if you crack your screen and replace it...
It will not last like a new one SO
If there is any age to it ...buy a new one, they are made to throw away after a couple of years.
