Specifically I enter with the connector very damaged, from another service it did not start correctly, I redid the BIOS now it turns on normal, it only generates image through the HDMI port it does not generate image in the display which I already discarded by placing the eDP cable and the LCD new

Hello. I need help with removing a BIOS password. I would appreciate your assistance.

Hi,

I have 2 x Lenovo Thinkbook G2 ITL laptops. They seems to be identical specs, both 11th gen, 1135G7 cpu, both 12gb ram and both 256gb M.2 ssd.
I have ensured both have the same latest bios and ec firmware.

One of them works totally fine however the other has charging issues.

I have compared both motherboards in diode mode and cannot find much of a difference anywhere.
I have swapped the motherboards over to the other casings and the issue transfers.

It's behaviour is it will connect at 20v on USB-C and always start to charge....

No power led blinking, just a black screen and fans spin after some time. I tried doing hard reset and CMOS and everything but nothing worked. Can you tell me what you did to fix it?...
