Do battery charger for Dell Laptop Short Circuit

ukcharger.co.uk I have a Dell laptop computer from that does not obtain electricity from your power adapter (Targus brand with interchangeable finishes). My suspicion is in the end-piece that will come using the ability adapter; each of the other components clearly show a suitable voltage change amongst favourable and floor, nevertheless the a single for my notebook displays zero (or very near). Even so, I want to rule out any problems with the power jack over the computer itself. I recently swapped out the factory jack for just a sturdier a single from Radio Shack. At the time, all of the connections have been soldered appropriately, and it worked without the need of incident till some months in the past, when all of a sudden it stopped getting energy. I have taken the pc apart and, up to now, very little appears from the standard; I recognize no scorch marks within the MOBO, as well as the soldering continue to seems good (great conductivity between the wires as well as real contact points over the jack). My issue is in truly screening for any brief employing the jack. Together with the set up, I read through close to 12kOhms on the jack... but this is often applying the ground lead within the multimeter on the good pin in the jack, along with the constructive guide to the ground part with the jack. If I check out it the right way, I get 0 (or quite modest) Ohms. When i try to go through the voltage, the correct polarity is preserved; roughly eight V when browse together with the beneficial direct to the pin and the detrimental lead on the ground, and -8 V oppositely. Eliminating the battery provides the resistance and voltage variance to close to zero in spite of where I place the qualified prospects. I believe that the frequent comments concerning the chargers being unable to cope is wrong and misleading, and should be ignored. Left plugged into the mains with computer switched off it will charge - if all other things are good - if the charger can power the computer, it can definitely charge the battery while the computer is off. No question. The computer draws much more current than is required to charge a battery alone. The problem lies elsewhere. Don't immediately rush out and buy a new charger based on this spurious claim.
