Hello,

I have disassembled the HP laptop and removed the RC battery. Now there is no more BIOS password.

But when turning on the laptop it keeps rebooting itself, i have checked the system logs and got the following error codes.

0xc000025

In sytem log

0502

03F0

Please help! 🙂

Best Regards

Does the laptop start to boot but Blue Screens and then tries to reboot???

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?????

@smimpi

That is it.

Try switching the memory from one slot to the other.

Dis-assembled again.. was only 1 memory slot inside and switched them without any result.

I connected the accu, cd drive but in system recovery i still get the notice.

Error you PC needs to be repaired.

0xc0000225 a device is not connected or missing

But when i do the system test all devices are working and connected :S :S :S

have now removed the SSD Drive and replaced it with an SATA will update
