The CMOS checksum is invalid.
The CMOS will be reset to the default configuration and will be rebooted.
Please check your BIOS Setup options to see if they changed.
CMOS Reset (502)
ENTER - Reboot the system

Press enter and flas original bios.

The original bios? you mean the original bios version ? or the last version but without your mod ? , and how can i flash the bios if the display is black when i press enter? i cant make nothing after pressing enter

Try to flash las unmodded version using recovery method.

where could i find that recovery method? i searched in google and found nothing

Format usb stick fat32, create HEWLETT-PACKARD folder on root, into it create BIOS folder, and into it another one named Current

Then take original bios and open with winrar, extract the file 01xxxx.bin into the Current folder

Power off notebook, remove battery and AC charger, insert the usb sitck, press and hold Win+b keys and connect ac charger and power on while the keys are pressed.

Wait a couple of minutes and notebook should flash the bios and rebbot.
