Hello everyone! I soldered the chip, but the laptop does not boot. When I press the button, everything starts working, all voltages rise, the keyboard backlight switches, but there is no image. You can turn it off by long pressing. I tried to make a flash drive with BIOS, but in recovery mode nothing happens, the power light blinks orange, but there are no sound signals. I have a programmer, and I can solder, but the BIOS downloaded from the official site in the unpacked folder weighs 24 megabytes, and besides, there are two BIOS chips on the board. Can someone make two BIOS files? Thanks!

Hello! Need help with laptop repair. I am an amateur myself, sometimes I repaired electronics for myself. In general, the laptop is new, on the 13th generation of Intel and graphics 40xx. A drop of liquid leaked through the keyboard, and as I understand it, it rotted away from the microcircuit. I got out my hair dryer to lift the microcircuit and try to solder it, but it does not work. And I can not find such a microcircuit to buy. Can you help? Thank you

Same issue bro, take 1 minute to get picture, after that FANs at full speed, than goes off. In your files, ME region is cleaned? If so, I have to look for hardware failure.

Find hardware issues , this is an origin bios.

Hi masters, anyone can help me with BIOS? Long story short, spilled unit, did not start at all. Found two burned resistors in 3.3/5V step down controler. Now unit start, but it takes 30-40 second to get a picture and than FANs start run at full speed and turn off after 20 seconds, so could be ME corrupted...

S/N: PF4MN0RM
Board: NM-F091

i9-13th + RTX 4070

Both dumps attached. I tried to clean, but I am not getting picture at all, even after minute.

There is no boardview and schematic, so would like to try BIOS first, BIOS area has been spilled anyway.

Thanks for any help.
