Microsoft Windows 10 (64-bit)

Last night upon shutting down my laptop windows showed a update.  I accepted and instead of this being a software update it proceeded to flash a bios update.   Never seen this before from windows?  The bios flash did not work and now I have a dead machine. I have tried the following:

 

1) BIOS reset holding the windows and b key then pressing the power button 1 to 3 seconds. 

2) Holding the power button for 15 seconds.

3) Downloading and making a USB disk to recover the bios.

4) Opened up the case looking for a CMOS battery. (Could not find one?) So I disconnected the internal laptop battery for about five minutes thinking it uses the battery instead of a small CMOS battery you normally see.

The caps lock on the keyboard flashes a 53 which means "Embedded controller times out waiting for bios"

Its as if the keyboard is not even being recognized?  I am lost at this point? Any help would be greatly appreciated

Welcome to the HP support community.

 

I understand that the BIOS update failed to update, follow these steps to fix the issue.

I recommend you to perform the following steps to isolate the issue and arrive at a fix:   

  • Remove the battery out. If the battery is integrated and does not have a latch to release it then leave the battery inside the laptop.    Disconnected AC adapter from the laptop.
  • Press and hold the power button for 15 seconds.  
  • Reconnect the battery and plug the AC adapter.
  • F6 + Power Button.
  • CMOS Rest ( combination of windows button and letter 'V' then push the power button ones and release the windows and letter 'V' after 5sec
  • If the laptop does not power on then please continue with the below steps:   
  • Disconnect the charger and remove the battery out.
  • Connect only the battery and check if the laptop powers on. Likewise, remove the battery out (if removal battery ) and connect only the charger and check if that helps.

Let me know how it goes.

To thank me for my efforts to help you, please mark my post as an accepted solution so that it benefits several others.

Cheers.
