      Boot from a Linux live cd like Puppy and check to see if the flash drive works. That will rule out a driver issue if an external keyboard and mouse work on it.

              Flash BIOS. If it still doesn't work i would suspect the southbridge. Although rare, they do fail in weird ways sometimes.

                  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 optiplex 7090 boot problem
                  by mpower1226
                  Hi masters, need your help in solving this mystery.

                  i have a dell optiplex 7090 micro that i bought from local kijiji.

                  when i turn it on, error comes out saying no hard disk.
                  i go to bios to check the boot option, only httpboot shows. If i try to add boot option, it only shows file search but nothing happens when i click.

                  i took out the ssd and put it into old laptop and format and installed the windows 10 and put it back into the desktop. It boots up and same error again no hard disk.
                  it seems as if the computer doesnt recognize the ssd...

                  **Need Help Unlocking BIOS and Hard Drive on Dell Precision 5820 Tower**
                  by federalhouse
                  Hi everyone,

                  I'm in need of assistance with a Dell Precision 5820 Tower. The BIOS is locked with "Dell Security Manager," preventing access to the HDD-1 hard drive.


                  **Background:**

                  I recently purchased this Dell Precision 5820 Tower from a recycler who salvages equipment from abandoned office spaces. The computer was left behind by its previous owner and was password locked. Given that it can run Windows 11, I saw this as an opportunity to upgrade my setup.


                  **What I've Tried So Far:**


                  1. I accessed                  ...
