Re: HP ZBook 17 G2 Locked BIOS Dump



Thanks for replying! About the original corrupted BIOS file, I just ordered CH314a to read my bios Winbond 25Q128FVSQ 1412. I'll keep you posted. I'll use this thread instead.

By the way, are you guys taking off the motherboard inside the laptop before you reflash or i just need to disconnect the CMOS batt and laptop batt?...

Re: HP Zbook 15 G1 LA-9241P BIOS +EC

Hello, I have HP Zbook 15 G1 that uses Winbond 25Q128FVSQ. Just recently, I disabled my Hybrid Graphics option through BIOS then after reboot, I'm getting 4 blinks of Capslock and numlock meaning I have Graphic interface controller error, from HP troubleshooting guide. I already removed the CMOS battery hoping it will reset to default but not working. I also tried to use their USB BIOS Recovery but to no avail.

Would reflashing BIOS dump will make this go away? or is there another way to restore my default settings?
