Probably millions of laptop chargers have been thrown out because the wires extruding from the charger broke. Then wires are vulnerable to breaking because they are thin and packing the charger into a backpack may flex the base of the extrusion. That extrusion is usually covered with thick rubber that isn’t adequate to keep it from being bent then broke. It may cost anywhere from $15 to $75 dollars for a replacement charger that may again break. The extruding connection should be re-engineered so that the recharger can be used after the extruding wire going to the laptop is broke since there is nothing actually wrong with the charger; the problem is in the broken wire that is difficult to reconnect with a splice after whittling away the rubber with a blade.
Some lizards regrow a tail after having it bitten off. Human engineers should be so clever with laptop chargers suffering broken wires. The charger itself should have a band on the exterior to let a detachable wire cord that goes to the laptop be connected and detached. In effect the charger would last years and the wire/cord to the laptop reattached and removed when packing the charger. Lenovo chargers are costly so I would think that Lenovo engineers would seek to make their computers more cost competitive with a no-problem line of battery chargers for laptops. Easy to pack and travel battery laptops are as important to laptop users as screen covers that allow safe packing of a laptop without having some heavy thing like a propane bottle in the same pack pressurize a plastic cover and bust the screen on the inside. It is not the case that everyone uses a laptop in ideal conditions or even has a motorized rolling suitcase to place it in at an airport. As may be said in the wild kingdom of A.I.; Life is unfair and then you die.
