Ac adaptor connector on laptop is broke--can not plug in

I can see the small post that is used as the connector ; looks like it was soldered on the motherboard. Shop service costs more than value of laptop. If not able to fix can I use the HD and battery in another similar laptop?

You should be able to use the Hard Drive in another laptop, the battery maybe not. If you get a laptop that is the same than sure use the battery.

I have an acer aspire 5100 and here recently the


Could be a bad battery and/or charger/AC Adaptor/DC Connector. Try to isolate the problem by removing the battery and then plugging the laptop charger in and starting the pc up. It should boot on the AC adapter alone. If it won't boot on the AC adaptor or it flickers and flashes while on the AC adaptor, I would first suspect the AC adaptor or the DC connector on the laptop (try wiggling the power plug at the PC to try and check the connector). If it behaves while on the AC adaptor without the battery present, I would suspect the battery. Either way, you may have to replace something.

I cannot get my acer aspire 4315 to AC power up. new batteries are ok. i have changed the power jack but no difference. please help


Check the light on the AC adaptor when plugged in to the laptop. If it is flashing, it indicates that the power is being "spat back". That is, not completing the circuit. Means that you have a fault in the charging circuit. I'd check for burning around the contacts where the DC port was soldered onto the board / or if the plug type, check the socket on the mobo is not damaged and is firmly soldered on.

After that, (if not already done) check the output voltage of the adaptor with a multimeter, might be a simple failure of the ac adaptor, even though it looks ok

Plug in ac adaptor to Dell inspiron 600m and does


Sounds like you have a broken DC Power jack. This is where the small socket where you attach the AC adaptor breaks loose from the motherboard , resulting in the laptop not charging properly or at all . If you have to wiggle the power jack to get a connection then this is definately theproblem.

Most computer reapir shops can do this for about $100. Or if your handy with a soldering iron and dont mind disassembling the laptop , you can always buy a new DC jack for your make and model off ebay and try to solder it yourself!

If you found this post helpful , please rate my post

The laptop just went dead. Does not power up off


check the pins on the adaptor connector that goes into the laptop socket....
they all must align correctly....
normaly it will have three pins, even if one is bent or mis-aligned it will not work....use a small screwdriver to slighly adjust the pins to the aprox correct postion...use a mignifying glass to have a look into the pins....

Cant use my adaptor


this seems to be a common problem. I have some experience soldering, so I opened up the case and replaced the part with a Radio Shack DC jack, soldering the tabs to the motherboard with insulated wire.
If you know someone who can solder, this isn't that hard a fix, once you figure out how to open up the case (in addition to the screws visible outside the case, there is one underneath the keyboard. Remove the faceplate over the speakers/HP Now buttons, then you can remove the keyboard.

Will not work with ac power adaptor but does with


Did you wiggle it a bit when plugged in? You can't tell from looking on the outside if the plug is fine because it goes bad inside where it is soldered. This is a very common problem, and have fixed many laptops with the same problem. All of them had a bad solder connection inside. Did you dtermine the plug was fine by plugging another ac adapter to your laptop or you just checked it visually? Hit me up I will solve this one for you.

Notebook won't power up with AC Adapter plugged in


your header for adaptor has worn out, or your AC adaptor had gone out. you can buy a UNIVERSAL adaptor which will fit any laptop from Newegg, fry's, office stores, etc. is a new adaptor does not work then you have to replace inside header. you can try taking a small knife and using it rub around inside to try to "revive" contacts. it is an expensive replacement cost

HP Pavillion dv6000 -when I plug in AC adaptor, it won't charge


Hi ja525,
If you have tested the power adaptor with a multi-meter to confirm it is OK or the other adaptor is also OK assuming that it is the correct voltage and at least the same current rating. Then the fault is most likely the power connector in the laptop.
To confirm this, power up as normal with the power adaptor connected and switched on, when the blue LED dims wriggle the power connector where it connects into the laptop and if the LED comes on or blinks, that means that you have a faulty power connector, it couls be a dry solder joint at the power connector.
It is possible that the power adaptor is shutting down (thermal overload) due to insufficient current capacity, Check the Amp rating of the laptop, it is usually on the lable on the botom of the laptop and check it against the power adaptor, the adaptor should be equal too or greater that the laptop's current rating.

To fix a faulty connector, you can dismantle the laptop and with a fine tip temperature controlled soldering iron, resolder the power connector and hopefully this will fix your prolem.

You can either buy a new motherboard or get the power connector on ebay and solder it on yourself(much cheaper solution)
