    Dell 2407WFPB

    Hi

    My Dell has this problem, it keeps rebooting repeating the same pattern.
    I can see a blue line but it is not able to display the word DELL and then reboot again. It keeps repeating.

    Can anyone tell to to troubleshoot the power supply board or the inverter board? Thanks.

      What does the power light do while this is happening?

      Sounds like a power supply issue so far....
      36 Monitors, 3 TVs, 4 Laptops, 1 motherboard, 1 Printer, 1 iMac, 2 hard drive docks and one IP Phone repaired so far....

              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 XPS Plus 9320 blue screen and rebooting
              by siuras676
              Hi everyone,
              I have a Dell XPS 9320 in for repair, and the machine has a strange issue.

              First, a bit of history: the laptop came in after liquid damage and was completely dead. I've repaired all the broken traces, replaced the damaged components, and it now powers on.

              However, it's now showing a Windows blue screen related to hardware (as seen in the picture), along with another Dell error I've never seen before.

              Has anyone encountered this issue on a Dell machine before and could point me in the right direction? I've checked the power rails around...

              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...

              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 thunderbolt firmware, extracted from dell firmware update exe. Padded to 1MB.

              Some models have a choice of 2 different firmwares, it depends on the dell SKU.
              The SKU is in brackets (****)
