                                CH341A will be more convenient to program if it KB9012 but its quit slow
                                you can check here easy to program

                                  Use your original BIOS, this Dell System Disable 16-hex code generator code has been released not to long ago, post your code and someone will respond with the corresponding 8-digit password. Supposing the code is still the same, try the password below these lines:
                                  Dell, System Disable: [8AE97D87D91D7497]

                                  IMPORTANT: Type password followed by CTRL-ENTER-ENTER, if that does not work after 2-3 tries, reboot computer, then just try password+ENTER.

                                          Dell E6400 PT434 type Battery Charging Stuck at 1%. Battery Pinouts?

                                          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've been trying to reset the bios password on this god-forsaken laptop, and due to it being a 8FC8, i've had little to no success with online password generators like https://bios-pw.org , not to mention how I don't want to burn a hole in my wallet by paying like 80 bucks on a weird sketchy website. Im using a local bios tool, except it requires a BIOS file, and I'm not entirely sure how to retrieve it.

                                          Forgot to mention the motherboard is a Dell Inc. 004WC7, VER. A01

                                          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...
