DGM monitor - jack no longer fits

well you lost it.
many monitors on the rear see tiny power port called DC COAX
that looks like laptop power.
this is a line power wart power pack.

here it is 12vdc 3amps. )more amps ok)

scads of them. AC to DC power.

When you connect the power adapter into the laptop, does the power LED light up? If not then - The battery adapter or the adapter's power lead or the laptop's power socket could be faulty. Check power adapter's DC plug that connects into the laptop power socket with a multi-meter, the voltage should be slightly higher than the voltage that is printed on the label on the bottom of the adapter. If the voltage is zero or way below the voltage that is printed on the label then the power adapter is faulty and needs to be replaced. If the adapter is OK then connect it to the laptop and power it up, then look at the power/battery charging LED light and wriggle the power plug in the laptop's power socket. If the power/battery LED light flashes and in a certain position this LED light stays firm, then the power socket is either faulty or it has a dry solder joint where it is connected to the motherboard. This can be repaired but it requires the laptop to be completely dismantled to get at this power socket and repair. If you cannot DIY then I suggest you get a quote first.

have you been tried to find at the shopjimmy.com or at the amazon.com?. you can replaced it with other adapter even not LG, the only need to considered is the same voltage and amper rating as will as the size of the output jack and polarity of the adapter you will replaced. which will fit and same polarity to your monitor .

Depends on what damage was caused. If the dc connector broke off cleanly and did not crack the board or caused any other damage, yiou can get a cheap dc socket from ebay from about £3.50, fitting it may cost a little more. I'd get it done by a reliable technician, unless you are handy with a soldering iron.

What worries me a little is the fact it will not boot with the battery, could just be down to the dc jack, but given the fact the kids pushed the wrong adaptor in the socket, it may have caused damage to the charging circuit

Check the battery is charged first and that power is getting to the laptop by the DC Jack. You can test this by setting a multimeter to 20V DC and touching one probe to the inner part of the DC jack and the other probe to the Outer (earth) of the DC jack (red to inner black to outer). I'm assuming the fuse in the plug of the adaptor is ok...

If there is power getting to the DC jack, check the connection to the DC jack socket on the motherboard, if it feels sloppy or loose, this is where the problem may be.

If the fit is tight and the AC adaptor is supplying power, you could have a ram issue. Romove each ram module in turn and try to see if the laptop boots then, if one stops it booting, it needs replaced.

Failing this, you could have a fault on the motherboard which will need technical investigation

Since the system is not working ion both battery and the adaptor it could be a faulty motherboard.. Call dell @18006249896 if you are in warranty.. Contact local tech if thr\e system is out of warranty....

The first thing to try is a different AC adapter. About half of all no power failures are the AC adapter no longer sends power to the system. You can also use a multimeter to check the DC output of the adapter (About 20VDC) If the AC adapter is putting out power or a known good adapter doesn't make any difference, then try reseating the LCD hinge cover cable connection. If still no power and especially if the power jack seems to be damaged, then a motherboard replacement or adapter jack replacement is required (Roughly $100 either way)
