    elitebook 840 G2 bios not charging

    Hello,

    I faced an issue with my HP EliteBook 840 G2 (motherboard chiclet), where the BIOS battery is not receiving any charge.

    The laptop is functioning properly, but when the main battery runs out of charge and I power on the laptop again, it resets the BIOS.

    Let me know if you need any further assistance or clarification.

    Thank you.

      The right BIOS Programmer - The right software (HP Elitebook 820 G1, 840 G2) no soldering, EC, DMI, ME
      by STKR123
      Greetings badcaps community,

      I havent done this for a long time and want to start it all again, after some evil and annyoing illness.
      So I apologize in advance, if some phrases might sound a bit like gibberish or illogical to you.

      Im trying my best to fully describe what I plan to achieve and hope I was choosing the right sub-forum for my new adventure.

      I have a Elitebook 820 G1 and a Elitebook 840 G2 here.

      These ask for a password when entering the BIOS, but boot just fine from the internal SSD.

      I learned that desoldering...

      Elitebook 850 G5 BIOS bricked
      by Guest
      Hello,

      I have an EliteBook 850 G5. After a Windows update, including a BIOS update, the notebook turns on, but the screen remains black, and the fans spin at high speed—nothing else happens.

      I assume the BIOS update failed, so I searched for the BIOS chip.

      I found a Winbond chip located between the RAM and the hard drive, which has a size of 32 MB.

      However, the BIOS update available on HP's website is only 17 MB in size. I used the update version that was previously installed when the notebook was still working.

      Can the corrupted...

      ASUS X54H laptop thinks it's always charging even with charger unplugged
      by flat-earther
      The charging indicator light on my ASUS X54H laptop is always on even when the charger is disconnected.

      Windows also shows ''Plugged in'' when charger is not connected.

      This problem started year ago gradually, when unplugging the charger the charging light took several seconds to disappear, then minutes, and now almost always on even when unplugged for an entire day.
      Strangely, before sometimes immediately when plugging in the charger the charging light went away, and later came back with it connected.
      If I let battery run out and say it has 3% Windows will...

      ASUS TP500LA BIOS request/repair/merge?
      by jbonavita
      Hi, my laptop wont boot at all
      With original bios no POST, only LED lights
      With alternative BIOS from model TP500LN (flashed via programmer) the notebook works again
      Some issues
      A- with bios from 500LN, it won't update from bios of model 500LA (from 500LN v203 to 500LA v300)
      B- If updated from 500LN version 203 to 300, the battery stops being recognized

      Things I tried

      1- Update / clear ME: Took the non working bios, made a backup, and did this: https://www.badcaps.net/forum/troubl...theory/trouble...
