Some time ago I bought a laptop lenovo, ThinkPad E540 .
Laptop has on the left side of the dual usb port.Lenovo ThinkPad E540 - broken USB problem
After 6 months, I noticed that one usb port is broken, it is lacking the plastic part at the center of the port.
Incorrect insertion of usb plugs can damage the motherboard.
I have only two efficient usb ports.
I reported the problem to the Lenovo service.
They said that mechanical damage is not covered under warranty.
After the next 6 months, while I was removing the pendrive from the USB port fell plastic part on my desk.
This was the second USB port on the left side. I have only one efficient usb right now.
The laptop was not hit, did not fall, I did not use force with usb port.
Laptop is on the desk constantly connected to an external monitor. Once I carried him out of the house to drive to the lenovo service.
I've used dozens of USB devices over the years and I never broke usb port.
I have a lenovo y580 from 3 years old and is in good condition.
I think this is defect in material of the dual port USB in ThinkPad E540 . Lenovo does not want to admit it.
They claim that it is a mechanical failure, no matter what reason was formed, not covered under warranty.
Is it normal that the USB ports in the Lenovo ThinkPad not withstand normal use ?
