Hi everyone im having trouble with this Laptop, i've replaced the old HDD (i cannot access it and i cant enter the BIOS with this HDD on) for an SSD but im not able to do any action: the BIOS keep resetting every time i disconnect it from the power supply (already changed and tested 2 different CMOS batteries) and i can't even change any settings, when i came to check if the settings are being modified everything is just like before (default settings). Ive tried to flash the Bios (USB flash win+B) with the correct one (HP support) for my Board ID (8330) but i get the "image verification failed" at the end. I cant boot from USB nor DVD with F9 (only EFI options) with supplies that work on other PCs. Any advice is welcome. Thank you for your patience, regards.
