CMOS checksum error on startup of hp laptop.

HP Recommended
HP Laptop 15-dy0xxx
Microsoft Windows 10 (64-bit)

The error message said there was a invalid CMOS checksum  when I punch in my serial to check for drivers I haven't put in it also says it is not compatible when it is the right serial.

Hi@sheeshsheesha, Welcome to the HP Support Community!

 

We reviewed your post and I understand that the  Notebook is not Powering ON,

 

Don’t worry, I assure you I will try my best to get this sorted.

 

I recommend you follow the below steps and check if it helps

 

Do you see a light at the place where the charger connects to the laptop? If yes then it indicates that the charger is all fine.

 

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.

Hope this helps! Keep me posted.
