Question about Lenovo 3000 N100 Notebook

1 Answer

Power connection broken

The 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.

This computer is 4 months past warranty.

    The Notebook is a Lenovo 3000 N200

  • Dan Eisch Feb 09, 2009

    So our question is very simple. How can we get the notebook fixed so the power cable will again plug in so the system will operate. Obviously there is a part that was broken and is now missing. the notebook is used by several people so we have no idea how it happened nor what happened to the part that was a part of the system and is now missing.

    As "TampaNative" said it is the jack that is missing/broken and needs to be replaced.

    Where can we get the part that needs to be replaced on the system board?


  • Dan Eisch Feb 09, 2009

    Do you have any idea where we can get the part that needs to be replaced on the system board? We may be able to do it without having to go to a service center if we can get the part. Or we can bite the bullit and pay for the replacement at a center, but hope they would not opt for replacement of the entire board.

    Thank you for your prompt response to our problem.

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.

    You are very luck, as your DC jack plugs in via a harness and will not require soldering. There is one on ebay at the link below.

My HP pavilion laptop has a problem when I power it the lights just go on then off


Start by making sure its plugged in and charging. most laptops have a light that is on if the cord is plugged in.if its plugged in and there is no light one wiggle on the connection on your power cord. start at the wall and check every connection. if the light blinks than you power cord is bad or the power port in the laptop has disconnected from the mother board. Some computer stores will have a loaner universal laptop charger you can borrow. I recommend borrowing there universal before you buy a new power cord

Dc jack of labtop getting vey hot


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.

If I could be of further assistance, let me know. If this helps or solves the issue, please rate it and give a testimonial for my response

My power cord started acting up on my laptop. now it wont power on at all, please help. do i need a new power cord?


It might be the cable totally cut (by the acting) but there might be your laptop's power adapter burn out by the acting. I suggest you to try from the easy ones (and the cheaper ones also), the cable.

In case of a problem or clarification, don't hesitate to post me a reply before rejecting my answer.
If you are satisfied, rate my solution with the "thumbs" or (even better) add a testimonial.

Wont power up, power cord good. once plugged into laptop power cord stops working


As long as you are abslolutely sure the power cord is functional, without a more indepth analysis, it seems/sounds like the AC connection to the board is broken.

To rule out this conclusion as the failure point, see if you can borrow/buy or better yet, recharge your battery {assuming it has no charge left at this point}

Stick the charged battery into your rig and if it works, yes. The AC connection is broken - nothing a little bit of soldering won't fix.
If it works, will need to ask more 'protocol questions to narrow down the situation'.

...when you reflect on the usage of the laptop, is there a bit of manhandling when connecting the power cord? Do you run it mainly plugged into AC? Dell is infamous for dodgy AC connections strongly lending credence to a broken AC connection to the mobo.

My ACER 5570z will not start up. When power cord


You most likely have a broken DC Jack on the motherboard. Thus, the battery cannot get a charge and the power supply is not making a connection to the system board because of the broken DC Jack.

Good Luck

Toshiba A205 won't charge unless I physically hold cord in


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.

Power Issue


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.

Power issue


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.

Best of luck.
