I forgot/lost the password to access the bios.
Tried to google troubleshooting. None of them worked, even took the laptop apart but could not find the CMOS. Is there a simple solution to this?

Leave it blank and hit Enter. After 3 times it will give you a halt code to post here.

Unfortunately, no passcode generator for hexadecimal halt codes. Most halt codes are numbers only.

None of the members here can generate a passcode to get you past the password prompt. Only "official" HP Support can help and they will probably tell you it requires motherboard replacement.
Unless @DavidPK has had any luck there is nothing we can do. Sorry.

There may be a small window of opportunity, however this does depend on the current revision of the AMI bios you're running.
Remove the rtc cell ( leave the power board connected ) then hold down the power button for 60 seconds - leave the machine like this for a couple of hours before re-inserting the rtc and re-assembling.
The bad news is that the rtc is on the 'wrong' side of the system board so will require quite a lot of disassembly - see Page 82 of your Maintenance & Service Guide.
