I just recently replaced 3 capacitors on the power supply board on my Dell 1905FP and it seemed to be working okay, being a neebie I read that all capacitors should be replaced just to be safe. So I changed out all the caps and now it will not turn on at all. I have checked all caps to make sure they have correct polarity. Can anybody give me a list or picture of all the cap values and locations so I can make sure I haven't mixed anything up. Thanks

Re: Dell 1905FP Capaitor Layout
1) Double check all your internal connections.
2) Does the power LED come on?
3) If you have a multimeter, check to see if the secondary DC voltages are present between the power board and logic board. At least one of them should be 5V DC.--- begin sig file ---

Re: Dell 1905FP Capaitor Layout
3 caps on the +5volts are 1000uf @ 16v and there is a 4.7uf on the +5 volts supply too
4 caps on the +24volts are 470uf @ 35v
1 cap that feed the +12 external power jack is 1000uf @ 25v
the two caps near the inverter transformers are 220uf @ 50v
hope this help

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... -
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... -
Hello,
My Dell Precision 5530 turned off suddenly when I was running Matlab and wouldn't turn on, show any lights, fans, and/or any signs of activity at all. I opened the case, removed the battery and looked at the board with a thermal camera while the AC adapter was connected. I saw that PU1252 was >120C so figured the chip had died on me Got the part number off the attached schematic (see Mouser link below) and replaced the chip. After replacing the chip the board (connected to AC adapter) was able to briefly power on, spin the fans a little bit, and turn on the front led lights.... -

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...
