??But when I remove the battery COMS, whoring after
Working after you remove the CMOS battery? What is the voltage of this CMOS battery?
See attached. Locate the diode mated to the CMOS / RTC battery. Remove all power. Meter in DIODE mode. Connect the meter leads across this part. The meter should tone beep and conduct in one direction (not the boy band; be a value of 0.3 to 0.6 volts) and will block when the meter leads are reversed. Confirm that this diode is not leaking.

I removed all the power, first diode 0.3v. Second diod 0.2, resistor is ok, but with battery computer It gives 3.3 volts but when I put the battery coms/rtc it gives 2.8 voltsAttached FilesComment

Hi,
I want to remove the Bios Password of my Lenovo IdeaPad U330p with the Lenovo autopatcher. I have the CH341A Black and I'm using NeoProgrammer. The Programmer has an LED that indecates when it reads or writes the Chip. When I try to Connect my Programmer to the Bios Chip (Winbond 25Q64FVSIQ) the LED lights up even though I didn't click on Detect botton in NeoProgrammer. If i click on Detect the LED still remains on and NeoProgrammer says "IC not responding".

Hello, this is a BIOS file for the Lenovo X270 laptop, read out through a CH341 programmer. I located error 1802 in the PE32 module. This is a detection for the network card's whitelist. How can I bypass or remove the whitelist check? My skills are limited, and I have tried many times but ended up with a black screen. How can I normally bypass this whitelist check? Please help me edit this BIOS file, thank you. It would be great if you could provide illustrations to guide me. Thank you very much!...
