problem: When disconnecting the power cord from the laptop, somehow,
someway, the actual plug unit was dislodged from the laptop itself.
Unfortunately, this was not noticed when it occurred and the part is
missing. This part would normally allow the power supply to make
connection with the cord connection. We can see the gold metal power
connections surrounded by yellow plastic casing, but I'm quite sure there had
been a silver/grey surrounding part into which the cord connected.

Re: Power connection broken
Sounds like the DC jack on the motherboard is broken. The jack is very inexpensive, but difficult to replace as it's surface mount soldered to the board and the laptop will have to be disassembled or the plastic case cut/modified to replace the DC jack.

A common weak spot on most laptops is the DC power jack. If someone trips on the wire while you have the power adaptor plugged into your laptop, chances are that the power jack will get damaged.
On most laptops the DC power jack is soldered directly to the motherboard and there are only three or four small pins holding it in place. Unfortunately that makes the power jack quite weak. Any sideways pulling of the DC power cord while attached to the laptop will usually dislodge at least one of these pins, breaking the solder around it. Modern laptops use quite a lot of power, from about 70W to 120W or even more. The bad electrical connection from the dislodged pin will cause sparks and heating that will eventually burn a hole through the motherboard and can even be a fire hazard.
The usual signs of that are:
The battery is not charging properly or stays at half charge despite that you have been using the power adaptor.
The screen flickers (the brightness is changing) while the power cord is plugged in. This is caused by the laptop switching between DC power (screen is brighter) and battery power (screen is dimmer).
The DC plug gets hot after a few minutes of use and may even smell of burning.
There are "scratching" sounds coming from the DC jack.
You need to take the unit apart and check/resolder the DC jack on the system board.

Disconnect the power cord from the back of the unit.
Connect the power cord to the back of the unit.
Press the On
) button to turn on the unit.and hold it down 10 se
this are the usual procedure..some do it by actually power off ..disconnect power cord..hold down the button ..and connect power cord with the button pressed..and after it powers..release the button ..try it both way s..the issue is that you probably used refilled cartridges and it needs to reset the counters..
The most likely problem is the power socket on the laptop, it may be just a dry solder joint and needs to be resoldered or it may be faulty and needs to be replaced. Either way to fix this, it requires the laptop to be dismantled to get at this power socket. Get a quote to repair, as it could cost a few dollars.
If it is a faulty cord/plug on the power adapter, this can be checked with a multi-meter. When you connect the multi-meter probes to the power plug the voltage should be steady and the reading should be slightly higher then the voltage that is printed on the label on the bottom of the power adapter. If the voltages fluctuates as you wriggle the plug then you have a broken wire in the plug. Replacing the plug would not cost much.
Could be the cord or your car plug. Does it fit snug? I have a 1996 Acura TL and the way the cigarette lighter is designed, I have to give it a bit of pressure so it makes good contact. try your unit in another vehicle and see if that solves the problem. If so, it's your car's cigarette lighter connection.
sounds suspiciosly like your chord fitting is damaged(loose wires at connection)and shorting.if possible try a friends power supply with same connecter type before renewing cos could be faulty(loose)connection at pc(inside)constant pushing and pulling of connections often causes 1. loose split or disconnected wires at male connection or 2.loose pins on motherboard female connection or broken housing (not difficult to repair)more difficult to find out how to get to internal connection.
The power cord might be bent or screwed up. Or option two, the actual power connection in your laptop (i.e. the place where you plug in the cord to the laptop) could be broken on the inside.
Worse case scenario, it could be both.
If it is just the laptop cord, try another connection cord that will plug into your laptop. If it works, buy a universal adapter.
If it doesn't work, and you notice that when you plug it in to the laptop, it kind of wiggles around a bit or seems loose on the "inside" of the laptop ... you might need to take it in to a shop to have a new power connector sodered into place in your laptop.
