The SSD drive was faulty. The new SATA drive i installed is working fine!

 

Strange that it passed the system tests :S :S :S

Removing the RTC battery was the method formally uised to remove BIOS passwords. It has not been that way for quite a few years now. 

 

It would have been far simpler to provide the system lock code to one of here in the forum so we could have given you an unlock code.

 

I suggest replacing the RTC battery.

That model laptop produces a HEX code.

 

Removing and replacing the RTC battery will work.

 

Removing the RTC battery may have changed the SATA settings???

That is good to know info. Thanks. There is no manual for this model in the support portal.

 

He should probably enter the BIOS and check to see if the SATA drive is the boot device and consider loading defaults.

Tried the setup defaults that didn't work.

 

Tried re-assembly to check all cables, but everything is connected well.

 

The laptop starts with the HP Logo and after a few seconds it goed black and then fully black for reboot. Then reboots to HP logo and reboots again.

 

I can enter menu trough ESC key and have run a system check. All devices are fine :S :S :S

 

Did get a new code in the log 0021

I have just noticed in the system check that RAM Slot 1 is Empty and and RAM Slot 2 has a module in it.

 

Maybe one is broken? And because it sees the first slot as empty it is not booting?????
