When connected with battery only, when you press the power off button, it turns on again after 10 seconds. With the AC power supply this does not happen.nds. With the AC power supply this does not happen. I have updated bios on official HP.

I updated the BIOS to an older version and the power on was fixed. Now the only thing I have left is that there is an error in the post, it does not detect official HP battery, error 605. Could you help me?
Thank you so much
