Question about IBM ThinkPad T40 2379 Notebook

2 Answers

Open the computer

I need to open the computer case to either tighten or re-solder the power cord connection. The connection on the back of the computer is loose and the computer has stopped taking a charge; however the computer is still usable with the power cord attached ONLY. The battery will go completely dead unless I fix the problem in short order.
How do I open the computer in the shortest way in order to service the power supply area?

    The question was not that of diagnosis. I need some expertise on opening the case so I can diagnose the problem. I am technically inclined and electronically savvy. I doo not desire advice at this point on anything other than opening the ThinkPad 2379-DJI case so that all the integral parts don't fall apart, and so I can put it back together when I am finished.
    Care to try again?

You stated that the power cord connection on the computer is loose, but if it operates while connected to the external power supply that would indicate to me that the connection is working. My thought at this point is either that the battery is not accepting a charge, indicating a defective battery, or that there is a problem with the motherboard that is preventing the battery from charging.

    If someone does not want ideas on how to find resolutions to their problems, maybe they should just try to resolve them on their own and not ridicule people for proposing alternatives.When I am trying to solve a problem with a particular computer, I first look at the web site for the manufactuer and look at their support section. They normally have links to that system and a download site for the manual, even if it is an older "legacy" model that is no longer manufactured.

Dell inspiron elec cord isn't firm so power turns off


Maybe it's the DC Jack that the power cord plugs into. If the jack is loose then you will experience the issue you are having.

Maybe your DC Power Jack which is where the power cord plugs into the computer is bad. Take an ink pen and push the tip inside the jack and see if the little pin wiggles, if so the jack is bad. You'll have to take the laptop apart to fix it. Most times it is soldered onto the motherboard, so you will have to desolder the old and solder a new one.

My LG M2362D keeps turning off automatically while I'm on the computer and then comes back on again within 10secs. Why does this happen intermittently?


Check the monitor cord to the PC, tighten them as also check the mother board for any loose connections. If possible try with an another monitor to confirm that the fault is with the monitor or not. If so open the monitor after disconnection of mains and solder all the suspected joints , seen to look dry. Check for loose components, capacitors, IC or resistor that detach the soldering connection when it is hot.

The power to my car radio cuts out then comes back on especially at stops


After time, the power output transistors heat-up and develop loose solder connections around the areas of the circuit board that draw high current - thus the signal becomes intermittent. Open the case and closely inspect the solder connections for partial or cold solder connections - re-solder the connection. Also, check for loose cables.

My computer will not turn on anymore


Try connecting the power-cord to a different wall-plug.

Look on the back for a "rocker" switch.
Flip it to the other side, and try the ON/OFF button.
If nothing, flip it back.

Open the case, and look for any small lamp on the motherboard.
If it is not lit, then the motherboard is not getting any power from the power-supply. Try a different power-supply.

Open the case, and look at the wires coming from the back of the front-panel to the motherboard. Look for any loose or non-connected wires. If one pair of "loose" wires is labelled 'POWER SW(itch)', then reconnect it to the appropriately-labelled pins on the motherboard.

If all else fails, take the computer to a qualified technician, for "hands-on" trouble-shooting.

Not charging battery. Dell lap top not recognizing ac adapter


The female power pin on the motherboard is probably loose and not making connection with the power cord. In that case, you would need to take it to someone that knows how to solder it back onto the board.

Dell inspiron 6000 power supply shot...


There are no internal power supplies in laptops. What has most likely happened is as your laptop fell it either landed on the part of the power cord that was sticking out the back/side of the computer or the tension was so great on the plug from it falling that the power supply connector on the motherboard has broken loose from the motherboard. I have seen this happen a lot. This is not a job for an amatuer. It takes someone with knowledge of laptop repair and motherboard repair. In your best case scenarios either the little strip that contains the power button has popped loose and is not making contact (seen this happen in one case) or the power supply adapter (not part of the laptop) has been damaged and torn some wires. In the first case just try to push that power button strip down on the laptop first to see if it will snap back in place. If you can find someone else that has the same adapter you can ask to borrow theirs for a few minutes. Medium case scenario is that it has broken the solder loose and just needs to be resoldered or a new power plug soldered in. Worst case scenario is that it has cracked the motherboard, which will be expensive to fix (it would have to be replaced). Continuing to try and use it in this state (unless it is the best case scenario) will further damage the motherboard as the electricity will start jumping to places it should not go and eventually destroy the motherboard.

Power cord shorts out


Hello,

Three possible issues,

1. the cord is bad, to test this go to local PC shop and buy a universal power cord test it with this cord. If it works then your cord was bad and you have purchased the correct part. If it doesnt work return cord for a refund.

2. The connector inside the laptop that the power cord connects to is loose and has a short in it. If its loose take it to a PC Shop that knows how to solder and have them reconnect it securely.

3. The laptop has incurred internal damage possibly from a fall or ruff handling. If this is the case the Motherboard may need to be replaced. If this is the case consider purchasing a new laptop.

Hope this helps,

A broken power pin is quite common on laptop computers. The pin gets damaged from plugging and unplugging the cord plus all the daily tugs and pulls on the cord. The cumulative damage breaks the connection from the power pin connector to the motherboard.

If you are mechanically inclined the repair can be made pretty easily. The pin usually runs anywhere from $5 - $15. It's the labor at a shop that is expensive ($99 - $250 or more).

Once you get the system repaired get a Cable Retention device and use it religiously so the problem doesn't reoccur.

Here's a video about the problem and the JerkStopper AC Cable Retention kit.
