    Stubborn Dell SX280

    Hi guys, I have an SX280 that is giving me some trouble. I've repaired these before with great success and know they are a troublemaker, but the one i have now i just can't figure out. When the board came in, it had a few bulging caps - the usual suspects 2200s etc. Those were replaced with no problems. But now when I turn it on, the power light clicks between green and amber off and on and the computer will keep restarting. The weird thing is that eventually after it reboots a few times, it will turn on for good and will run perfect after that. I can reboot it numerous times and it still works, but if i unplug the power and let the board drain then it starts doing its clicking thing again on boot.

    Any ideas on what could be the culprit? Time is kind of tight so I would rather not replace them all if I can avoid it - just looking for a place to start. Thanks.

      The small caps can dry out too in hot boxes.

          yeah, complete the recap... partial recapping in a hot-box like that is never a good idea.

              Dell E6400 PT434 type Battery Charging Stuck at 1%. Battery Pinouts?
              by Bowline
              My question pertains to understanding the control circuity inside a Dell PT434 type battery used in Dell E6400, E6410 and other Dell notebooks?

              Does anyone have a circuit diagram for the inside of a Dell PT434 battery and/or a description of how the control lines work to control this battery?

              My reason for asking is I have a battery which I cannot get to charge beyond 1% in a Dell E6410 or E6400.
              The LED bar graph charge indicator on the battery shows one LED lighted when the info button is pressed.

              Dell Pro 13 Plus PB13250 Bios Unlock
              by Akhlz001
              Hi,

              Could someone help trying to unlock this BIOS, seems that Dell have changed the layout of new Dell Pro 8FC8 bioses from checking HXD - 4000 bits do not need changing, only 2000. However after FF the section starting from '01000' upto 2000 bits and then soldering the chip back it seems that the microchip on the motherboard is recovering the bios back to original settings after first boot. Has anyone found a way to crack this extra layer of security Dell have implemented? Seems both HP and Dell have upped bios security to match Lenovo by implementing extra measures on a separate...

              I would like to share my experience about charging issues with Dell power supplies with the tech community. I am working on a Dell Inspiron 5590, Mainboard 18778-1 with charging problems. The device can be switched on and works so far, only the message appears at startup:

              Alert! The AC power adapter wattage and Type cannot be determined. The battery may not change. The System will adjust the performace to match the power available.

              The power supply unit is not recognized in the Bios and the charging process is set to "idle". I use original Dell battery, type...
