    DELL GX280 problem-help!!

    Just got one from auction, after power on, can see DELL logo, then screen has little flick and become blank after 10 seconds. Checked google, and opened the case found three nichicon 820uf, 6.3V caps near RAM slot, they all bulged. all other capacitors are fine, they are panasonic or rubycon with flat top. I replaced three nichicon caps with other three caps which are 1000uf 6.3V, 105C, but still has same symptom-blank screen after boot up.
    Question is, do I need to sold the exactly same parameter caps? Do I need to sold a some kind of low ESR caps? Because the size of new one is even smaller than bad nichicon one.

    Thanks in advance for any good comments.

          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.
          I have tried multiple different Dell power adapters. My Dell...

          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...

          Dell Inspiron 5590 Board 18778-1 no charging, charging not possible
          by master3112
          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...

          Dell Latitude 3440 - Service tag ending in 0001 - Locked!
          by dell_sadness
          BIOS password locked Dell Latitude 3440 (Service tag B4HNJX3)
          Have extracted the BIN and want to know how to rebuild a clean BIOS

          I have come across the 8F8C patcher but not sure if that would work in my case as the service tag ends in 0001.
          I tried it and although the log states it patched several mentions of 8F8C in the BIN, I haven't flashed it yet in case such a patch wouldn't work.

          Have also tried to extract a clean BIN file from Dell's .exe BIOS updates using 'Dell PFS Extractor', but not confidently; Ended up with a 25MB file instead of the same 32MB...
